The present invention relates to flavored water with an enhanced sweetness and a method for producing such flavored water. The present invention also relates to a method for enhancing a degree of sweetness of flavored water and a concentrate for providing flavored water.
The present invention also relates to a sparkling beverage with an enhanced sweetness and a method for producing such a sparkling beverage. The present invention also relates to a method for enhancing a degree of sweetness of a sparkling beverage and a concentrate for providing a sparkling beverage.
Humans have five sensory systems, and the sense of taste is one of the sensory systems of humans. The taste receptor organ to receive tastes is called taste buds, which exist on the fungiform papillae existing over a wide area, mainly on the tip of the tongue, on the vallate papillae existing on a limited area of the back of the tongue, and on the foliate papillae. The taste buds are a cell assembly composed of elongate cells, called taste cells, and basal cells. The taste cells protrude microvilli toward the tongue surface, and form synapses at bottom of the cells with taste nerve fibers entering the taste buds. Tastes we usually sense are transmitted as taste information via the taste nerves to the brain, where the tastes are perceived. Known taste receptors of sweetness include T1R2 and T1R3. T1R2 and T1R3 are reported to form hetero-dimers (Non-patent Literatures 1 to 3).
Although various studies have been made on the sense of taste, little has been revealed yet in this field. We usually experience various tastes of foods. Foods that seem to be tasty have appropriately mixed and well-harmonized tastes. The taste of foods may be tasted as a single taste in some cases, but is often tasted as a mixed taste of various tastes, which are associated with one another.
Meanwhile, foods have been required to have lower calories in addition to a good taste in recent years. This relates to a fact that lifestyle-related diseases such as obesity and diabetes are regarded as a problem.
However, to produce lower-calorie foods, their sugar concentration has to be maintained low. This is an obstruction in the case of providing foods that exhibit low calories and a good taste.
As an example of a contrast effect, which is an interaction of tastes, there has been long known a phenomenon in which addition of salt to sweet red-bean soup enhances sweetness. There is an example that reports the interaction between saltiness and sweetness by focusing on this phenomenon, and it is concluded that the interaction between sweetness and saltiness requires sweetness that is strong to a certain degree (a 15% solution) and a salt concentration that is high to a certain degree (0.1 to 0.2%) (Non Patent Literature 4).
Further, studies have been also made on the increase of a sweetness by adding sodium in a low concentration to a natural sugar and a specific high-intensity sweetener (Patent Literature 1).
Under the above circumstances, the development of a novel method capable of enhancing a sweetness of beverage containing a sweetener has been much awaited.
The present inventors succeeded for the first time in enhancing a sweetness of flavored water containing a sweetener by containing a sweetener, and an amino acid or a derivative or a salt thereof in a concentration so low as to not be detectable by the human, or containing a sweetener, and sodium and an amino acid or a derivative or a salt thereof in concentrations so low as to not be detectable by the human.
The present inventors succeeded for the first time in enhancing a sweetness of a sparkling beverage containing a sweetener by containing a sweetener, and an amino acid or a derivative or a salt thereof in a concentration so low as to not be detectable by the human, or containing a sweetener, and sodium and an amino acid or a derivative or a salt thereof in concentrations so low as to not be detectable by the human.

The flavored water of the present invention has an enhanced sweetness as having been already mentioned. Whether or not the sweetness of the flavored water of the present invention is enhanced can be evaluated by panelists who received sensory trainings. Further, for the sweetness intensity of the flavored water of the present invention, each standard flavored water to be the sweetness standard is prepared with each of sucrose concentrations assigned as sweetness intensities 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, and 15 and panelists compare the sweetness of the flavored water of the present invention with the sweetness of such each standard flavored water thereby to measure the sweetness of the flavored water of the present invention. Note that such each standard flavored water having a sweetness intensity of 1, 2, . . . 15 is prepared by adding sucrose in such a way that a sucrose content is 1 g/100 g, 2 g/100 g, . . . 15 g/100 g to the flavored water to which sucrose is not added.
Furthermore, of such standard flavored water having a lower sweetness than the flavored water of the present invention in the above measurement, the standard flavored water having the closest sweetness to that of the flavored water of the present invention is selected and adjusted in such a way as to have the same sweetness as that of the flavored water of the present invention by adding sucrose to the selected standard flavored water, during which a sweetness intensity of the flavored water of the present invention can also be measured from a sucrose content in the adjusted standard flavored water.
Other examples of the method for measuring a sweetness of the flavored water of the present invention include a sweetness intensity rating using Visual Analogue Scale (VAS method). For the VAS method, literatures in The journal of Japanese Society of Stomatognathic Function (2014) 20 pp. 115-129 (“Construction of a Screening Test for Gustatory Function in Four Basic Tastes” by Toyota et al.) and the like can be referred. Specifically, in the measurement of sweetness intensity by the VAS method, for example, evaluators define sweetness intensities as “not sweet at all” at the lower end and “nothing is sweeter than this” at the upper end and, using a piece of paper on which a vertical line indicating the intensities of sweetness on the straight line, assess a sweetness intensity sensed at that time by showing a position on the straight line.
The sweetness intensity of the flavored water of the present invention is not particularly limited as long as it is acceptable as flavored water and may be, in terms of the degree of sweetness, for example, 4.0 to 20, 4.0 to 15, 4.0 to 12.5, 4.0 to 10, 4.5 to 20, 4.5 to 15, 4.5 to 12.5, 4.5 to 10, 5.0 to 20, 5.0 to 15, 5.0 to 12.5, 5.0 to 10, 5.5 to 20, 5.5 to 15, 5.5 to 12.5, 5.5 to 10, 6.0 to 20, 6.0 to 15, 6.0 to 12.5, 6.0 to 10, 6.5 to 20, 6.5 to 15, 6.5 to 12.5, 6.5 to 10, 7.0 to 20, 7.0 to 15, 7.0 to 12.5, 7.0 to 10, 7.5 to 20, 7.5 to 15, 7.5 to 12.5, 7.5 to 10, 7.5 to 9, 7.5 to 8, 8.0 to 20, 8.0 to 20, 8.0 to 15, 8.0 to 12.5, 8.0 to 10, 8.5 to 20, 8.5 to 15, 8.5 to 12.5, 8.5 to 10, 9.0 to 20, 9.0 to 15, 9.0 to 12.5, 9.0 to 10, 9.5 to 20, 9.5 to 15, 9.5 to 12.5, 9.5 to 10, 10.0 to 20, 10.0 to 15, 10.0 to 12.5, 10.5 to 20, 10.5 to 15 or 10.5 to 12.5.

Further, an energy (total energy, TE) of the flavored water of the present invention may be, depending on an embodiment (for example, an embodiment containing a caloric sweetener), 0<TE≤50 Kcal/100 ml, 0<TE≤45 Kcal/100 ml, 0<TE≤40 Kcal/100 ml, 0<TE≤35 Kcal/100 ml, 0<TE≤30 Kcal/100 ml, 0<TE≤24 Kcal/100 ml, 0<TE≤22 Kcal/100 ml, 0<TE≤20 Kcal/100 ml, 0<TE≤15 Kcal/100 ml, 0<TE≤10 Kcal/100 ml or 0<TE≤5 Kcal/100 ml (that is, it never is completely 0)
The components (a) and (b) can be in any combinations. As shown in examples to be described later, the addition of the component (b) to the component (a) enables to provide a sweetness intensity Xb, which is higher than the sweetness intensity Xa of the component (a) alone. That is, the sweetness of the component (a) can be enhanced by the component (b). For this reason, flavored water can be produced without using or with a reduced amount of highly caloric sucrose while maintaining the sweetness equal to flavored water containing sucrose. Thus, the design of new low-caloric flavored water is enabled. In the case of designing zero-calorie flavored water, a high-intensity sweetener having particularly good-taste quality such as rebaudioside D (hereinafter, rebaudioside is sometimes abbreviated as “Reb”) and rebaudioside M is used for the component (a) and D-allulose or erythritol is used as an additional sweet substance thereby to improve a sweetness with a low-concentration amino acid. In the case of adjusting flavored water to be not zero calories but a low calorie, a caloric sweetener such as sucrose, glucose, fructose, or sorbitol can be contained as an additional sweet substance.
The high-intensity sweetener (hereinafter, sometimes abbreviated as the “sweetener (a)!” or “component (a)!”) means a compound having a more intense sweetness than sucrose and encompasses naturally occurring compounds, synthetic compounds, and combinations of naturally occurring compounds and synthetic compounds. The high-intensity sweetener has, in the same amount as sucrose, a sweetness 5 times or more, 10 times or more, 50 times or more, 100 times or more, 500 times or more, 1000 times or more, 5000 times or more, 10000 times or more, 50000 times or more or 100000 times or more, of that of sucrose.

In a preferable embodiment of the present invention, the high-intensity sweetener is selected from a high-intensity sweetener having a good taste quality. As used herein, the “high-intensity sweetener having a good taste quality” means a high-intensity sweet substance having one or more taste qualities selected from, when compared with rebaudioside A (RebA), (1) less astringent taste, (2) less metallic taste, (3) less aftertaste of sweetness, and (4) less bitterness. Whether or not a certain sweet substance has the above taste quality is already known or can be determined based on a sensory evaluation. Nonrestrictive examples of the high-intensity sweetener having a good taste include RebD, RebM, a luo han guo extract, a mogroside (for example, mogroside V), thaumatin, brazzein or a combination thereof.
In an embodiment of the present invention, the high-intensity sweetener may be those naturally occurring in plants and the like or those artificially produced (for example, bioconversion or chemosynthesis) but is preferably a naturally occurring sweetener. As used herein, the “naturally occurring” does not mean that a high-intensity sweet substance contained in the flavored water of the present invention is a natural product but a high-intensity sweet substance contained in the flavored water of the present invention may be a product artificially (for example, by bioconversion) produced (non-naturally occurring product) as long as the same substance naturally occurs.
Nonrestrictive examples of the sweetener (a) include rebaudioside A (RebA), rebaudioside D (RebD), rebaudioside M (RebM), neohesperidin dihydrochalcone, glycyrrhizin, thaumatin, monellin, mogroside, rubusoside, curculin, mabinlin, brazzein, pentagin, phyllodulcin, hernandulcin, miraculin, Stevia rebaudiana plant-containing sweet components, Siraitia grosvenorii plant-containing sweet components, Glycyrrhiza glabra plant-containing sweet components, Rubus suavissimus S. Lee plant-containing sweet components, Hydrangea macrophylla var. thunbergii plant-containing sweet components, Sclerochiton ilicifolius plant-containing sweet components, Thaumataococcus daniellii Benth plant-containing sweet components, Dioscoreophyllum volkensii plant-containing sweet components, Curculigo latifolia plant-containing sweet components, Richardella dulcifica plant-containing sweet components, Pentadiplandra brazzeana plant-containing sweet components, Capparis masaikai plant-containing sweet components, Lippia dulcis plant-containing sweet components and derivatives thereof, and combinations thereof. In a specific embodiment, the sweetener (a) contains RebA, RebD, RebM, a mogroside (for example, mogroside V) or a combination thereof. In another specific embodiment, the sweetener (a) contains RebD, RebM, a mogroside (for example, mogroside V), thaumatin or a combination thereof. In a preferable embodiment of the present invention, a high-intensity sweetener having a good taste quality contains at least one selected from the group consisting of RebD, RebM, mogroside V, a luo han guo extract, and a combination thereof. In an embodiment of the present invention, the sweetener (a) consists essentially of a sweetener other than major components of Stevia sweeteners such as RebA and stevioside. As used herein, the “consists essentially of . . . ” means that the sweetener used in the present invention may contain major component(s) of Stevia sweeteners as long as the effects of the invention are not affected. For example, preferably 90% or more, more preferably 95% or more, or further preferably 98% or more of the sweetener (a) for use in the present invention consists of a sweetener other than RebA and stevioside.
RebA, RebD and RebM may be directly extracted from Stevia, or may be obtained by adding glucose to a compound having another structure, contained in a Stevia extract.
The Luo han guo extract as a sweetener is an extract of Luo han guo containing a sweet substance derived from Luo han guo, approved in various countries including Japan as a food additive and commercially available. Examples of the sweet substance derived from Luo han guo include mogroside V, mogroside IV, 11-oxo-mogroside V, and Siamenoside I.
Mogroside V is a kind of the major mogrol glycosides contained in Luo han guo and documented to have a good-quality sweetness property close to sucrose when compared with rebaudioside A. Mogroside V may be obtained from a luo han guo extract (for example, an alcohol extract of Luo han guo) by purification with chromatography or the like. Alternatively, mogroside V may be obtained by adding glucose to a compound having another structure, contained in a luo han guo extract.
The luo han guo extract preferably contains mogroside V and the ratio thereof is not limited and may be 10 wt % or more, 15 wt % or more, 20 wt % or more, 25 wt % or more, 30 wt % or more, 35 wt % or more, 40 wt % or more, 45 wt % or more, 50 wt % or more, 55 wt % or more, 60 wt % or more, 65 wt % or more, 70 wt % or more or 75 wt % or more, of the total dry weight of a luo han guo extract. The content of mogroside V may be determined by a known technique such as liquid chromatography. The luo han guo extract may be obtained by extracting a fruit of Luo han guo (Siraitia grosvenorii) with a suitable solvent (for example, an aqueous solvent such as water, an alcohol solvent such as ethanol or methanol, or a mixed solvent of an aqueous solvent and an alcohol solvent such as water-containing ethanol or water-containing methanol), and then optionally carrying out a treatment such as degreasing, purification, concentration, and drying.
Mogroside V may be one having a high purity, and may be, for example, one having a purity of 80% or more, 85% or more, 90% or more, 91% or more, 92% or more, 93% or more, 94% or more, 95% or more, 96% or more, 97% or more or 98% or more. Mogroside V obtained by purification of a luo han guo extract, of course, has a smaller amount of incorporation of a luo han guo extract component other than mogroside V, as it has a higher purity.
In other embodiments of the present invention, mogroside V may also be one having a lower purity, and may be, for example, one having a purity of 50% or more, 55% or more, 60% or more, 65% or more, 70% or more or 75% or more. For example, when the sweetness intensity of sucrose per unit concentration Brix 1 is defined as a degree of sweetness of 1, the degree of sweetness of Mog V having a purity of about 65% is about 175. In other embodiments of the present invention, a luo han guo extract containing about 30 wt % of Mog V may be used as the high-intensity sweetener, and, when the sweetness intensity of sucrose per unit concentration Brix 1 is defined as a degree of sweetness of 1, the degree of sweetness of the luo han guo extract is about 100.
The high-intensity sweetener is contained in an amount corresponding to a sweetness intensity Xa, as described above. When the sweetness intensity of sucrose per unit concentration Brix 1 is defined as a degree of sweetness of 1, a degree of sweetness of rebaudioside D is about 225, a degree of sweetness of rebaudioside M is about 230, a degree of sweetness of rebaudioside B is about 325, a degree of sweetness of rebaudioside A is 200 to 300 (median value 250), a degree of sweetness of rebaudioside N is 200 to 250 (median value 225), a degree of sweetness of rebaudioside O is 200 to 250 (median value 225), a degree of sweetness of rebaudioside E is 70 to 80 (median value 75), a degree of sweetness of a luo han guo extract (containing 40% of Mog V) is about 130, a degree of sweetness of mogroside V is about 270, a degree of sweetness of thaumatin is 2,000, and a degree of sweetness of brazzein is 500 to 2000 (median value 1250). The numerical value obtained by multiplying these degrees of sweetness by a concentration (w/v % (considered to be the same as w/w % in the case of a beverage)) of the high-intensity sweetener in the flavored water is a sweetness intensity of the high-intensity sweetener. When Xa of such a sweetener is herein determined, the above degree of sweetness (median value when a numerical value range is shown) is used. A relative ratio of a degree of sweetness of each sweetener to a degree of sweetness of 1 of sucrose can be determined from, for example, a known sugar sweetness conversion table (for example, information “Beverage term dictionary”, page 11, Beverage Japan, Inc.). When a numerical range of a degree of sweetness is herein shown, a median value is adopted. Herein, in the case of a sweetener whose degree of sweetness is different with respect to each literature, a relative ratio of a degree of sweetness to a degree of sweetness of 1 of sucrose can be determined by a sensory test. Examples of such a sensory test include a method involving preparing samples where sucrose is added to pure water so that Brix is 3.0 to 5.0 by 0.5, and selecting a sample where sucrose is added, having a sweetness intensity equal to that of an aqueous solution having a predetermined concentration of a sweetener, among such samples.

As used herein, the threshold of amino acids means a detection threshold or a taste recognition threshold. The detection threshold means a minimum concentration at which the difference from water can be clearly identified but a type of the taste (for example, bitterness, sourness, and sweetness) does not have to be always recognized, and the taste recognition threshold means a minimum concentration at which a taste can be recognized (for example, Eur J Clin Nutr (2004) 58, 629-636). The threshold (detection threshold) of amino acids is organized by Susan S. Schiffman et al. in “Comparison of Taste Qualities and Thresholds of D- and L-Amino Acids”, Physiology & Behavior, Vol. 27, pp. 51-59 (1981). For example, a detection threshold of each amino acid is as follows: glycine (30.9 mM), L-threonine (25.7 mM), L-serine (20.9 mM), L-alanine (16.2 mM), L-proline (15.1 mM), L-glutamine (9.77 mM), L-isoleucine (7.41 mM), L-phenylalanine (6.61 mM), L-leucine (6.45 mM), L-valine (4.16 mM), L-methionine (3.72 mM), L-tryptophan (2.29 mM), L-asparagine (1.62 mM)), L-histidine (1.23 mM)), L-arginine (1.20 mM)), L-lysine (0.708 mM)), L-aspartic acid (0.182 mM), L-glutamic acid (0.063 mM), L-cysteine (0.063 mM). Additionally, the taste recognition threshold is known to be about 1.5 to 2 times the detection threshold (Yuki Yamauchi et al., “WHOLE MOUTH GUSTATORY TEST (PART1)—BASIC CONSIDERATIONS AND PRINCIPAL COMPONENT ANALYSIS—”, Journal of The Oto-Rhino-Laryngological Society of Japan, vol. 98 (1995) No. 1, p. 119-129, and Reiko Ohmori, “Comparisons of the taste sensitivity between three generations”, The bulletin of the Faculty of Education, Utsunomiya University, Section 1 (2013) Vol. 63 p. 201-210)).
In the present invention, it is preferable that a measured value be used as the taste recognition threshold of an amino acid. A taste recognition threshold of an amino acid can be determined by preparing amino acid-containing aqueous solutions in several concentration levels and tasting in the order from low concentrations to high concentrations to carry out a sensory test by which the taste can be sensed or not. A concentration at which a difference from water is detected is defined as a detection threshold and a concentration at which a taste is recognized is defined as a recognition threshold. For example, for an amino acid for which a theoretical value (a literature value) is already established, aqueous solutions in several concentration levels close to such a concentration are prepared and several persons who received sensory trainings carry out the test thereby to determine these thresholds. In the case of L-alanine, a detection threshold described in literatures is 16.2 mM and a theoretical recognition threshold calculated from such a detection threshold is 32.4 mM, and a sensory test using aqueous solutions in several levels selected from 5 mM, 10 mM, 15 mM, 20 mM, 25 mM, 30 mM, and 35 mM is carried out thereby to measure a recognition threshold.

The flavored water of the present invention may contain a sweetener other than the high-intensity sweetener of the component (a). In the present description, the “sweetener” means any substance or a substance group which causes a sweetness response. Sweeteners can be classified into carbohydrate sweeteners and non-carbohydrate sweeteners based on structural characteristics and also into low-intensity sweeteners and high-intensity sweeteners based on the degree of sweetness. Further, sweet substances can also be classified based on the energy (calorie) into caloric sweeteners and non-caloric sweeteners. Further, sweet substances can also be classified based on the availability into natural sweeteners and artificial sweeteners. Note that, when the flavored water comprises a fruit juice and the fruit juice contains a fruit-derived sweetener (fructose or the like), such a sweetener is also encompassed in the sweetener here described. Also when the flavored water contains an extract and the extract contains a sweetener, the above may apply.
The carbohydrate sweetener is not limited and examples include starch sugars such as sucrose, lactose, glucose, maltose, starch syrup, a high-fructose corn syrup, and fructose, sugar alcohols such as erythritol, sorbitol, mannitol, maltitol, xylitol, and palatinit, sucrose, palatinose, fructooligosaccharide, Coupling Sugar®, galactooligosaccharide, lactosucrose, raffinose, soyoligosaccharide, and honey. Further, the carbohydrate sweetener includes rare sugars.
The rare sugar refers to a monosaccharide that occurs in very small quantities in nature and derivatives thereof. For example, the rare sugar includes naturally occurring aldoses other than D-glucose, D-galactose, D-mannose, D-ribose, D-xylose, and L-arabinose, naturally occurring ketoses other than D-fructose, and naturally occurring sugar alcohols other than D-sorbitol. Nonrestrictive examples of the rare sugar include ketoses such as D-tagatose, D-sorbose, D-allulose (D-psicose), L-fructose, L-allulose (L-psicose), L-tagatose, and L-sorbose, aldoses such as altrose and D-allose, and sugar alcohols such as xylitol, erythritol, and D-talitol.
The caloric sweetener typically means sweet substances having an energy of 4 kcal/g. An energy of a sweet substance is already known or can be determined by measuring a content by HPLC or the like and calculating by multiplying the content by an energy conversion factor, or measuring a heat of physical combustion using a calorie meter (for example, bomb calorimeter) and correcting the heat with a digestion-absorption rate, an excreted heat or the like. Nonrestrictive examples of the caloric sweetener include sucrose, lactose, glucose, maltose, starch syrup, a high-fructose corn syrup, and fructose.
The non-caloric sweeteners typically refer to those having the nature of being difficult to be digested in the body and consequently having a reduced energy to be taken into and means sweet substances having an energy of less than 2 kcal/g, preferably less than 1 kcal/g, and further preferably less than 0.5 kcal/g. Nonrestrictive examples of the non-caloric sweetener include non-caloric hexoses such as allulose (psicose) and allose, non-caloric pentoses such as xylose and arabinose, non-caloric tetroses such as erythrose and threose, and non-caloric sugar alcohols such as erythritol and allitol.
Further, the sweet substances can also be classified based on the energy (calorie) level. For example, the sweet substances can be classified into sweet substances having an energy of 4 kcal/g or more and sweet substances having an energy of less than 4 kcal/g. The sweet substances having an energy of less than 4 kcal/g can further be classified into sweet substances having an energy of less than 3 kcal/g, sweet substances having an energy of less than 2.5 kcal/g, sweet substances having an energy of less than 2 kcal/g, sweet substances having an energy of less than 1.5 kcal/g, sweet substances having an energy of less than 1 kcal/g, sweet substances having an energy of less than 0.5 kcal/g, sweet substances having an energy of 1 kcal/g or more and less than 4 kcal/g, sweet substances having an energy of 2 kcal/g or more and less than 4 kcal/g, sweet substances having an energy of 3 kcal/g or more and less than 4 kcal/g, sweet substances having an energy of 2 kcal/g or more and less than 3 kcal/g, sweet substances having an energy of 1 kcal/g or more and less than 2 kcal/g, sweet substances having an energy of 0 kcal/g or more and less than 2 kcal/g, or sweet substances having an energy of 0 kcal/g or more and less than 1 kcal/g. Examples of the sweet substance having an energy of 4 kcal/g or more include sucrose, lactose, glucose, maltose, starch syrup, a high-fructose corn syrup, and fructose, examples of the sweet substance having an energy of 2 kcal/g or more and less than 4 kcal/g include sorbitol, xylitol, D-xylose, D-ribose, D-tagatose, and arabinose, and examples of the sweet substance having an energy of 0 kcal/g or more and less than 2 kcal/g include D-allulose, erythritol, allose, erythrose, threose, and allitol.
The low-intensity sweetener means a compound having about the same degree of sweetness as that of sucrose (for example, less than 5 times, about 0.1 to 2 times, about 0.5 to 1.5 times that of sucrose). Nonrestrictive examples of the low-intensity sweetener include low-intensity sugar sweeteners such as sucrose, a high-fructose corn syrup, glucose, fructose, lactose, maltose, xylose, lactulose, fructooligosaccharide, maltooligosaccharide, isomaltooligosaccharide, galactooligosaccharide, Coupling Sugar®, and palatinose, and sugar alcohol low-intensity sweeteners such as maltitol, sorbitol, erythritol, xylitol, lactitol, palatinit, and reduced starch saccharified products. Further, the low-intensity sweetener includes rare sugars, caloric sweeteners, non-caloric sweeteners, carbohydrate sweeteners, non-carbohydrate sweeteners, natural sweeteners, and artificial sweeteners as long as the degree of sweetness is in the above range.
The flavored water in an embodiment of the present invention contains a low-intensity sweetener. In other embodiments of the present invention, the following flavored water (hereinafter also referred to as the flavored water of Embodiment A) is provided.

As used herein, the “sweetness intensity” means an intensity of sweetness of a substance. For example, when the sweetness intensity of sucrose per unit concentration Brix 1 is defined as a degree of sweetness of 1, a degree of sweetness of glucose is 0.6 to 0.7 (median value 0.65). A numerical value obtained by multiplying this degree of sweetness by a concentration Brix value of glucose is the sweetness intensity of glucose. Thus, when a concentration of glucose is Brix 1.5, the sweetness intensity of glucose is 0.65×1.5=0.975. The degrees of sweetness of common sweeteners are as shown in Table 1 described with respect to the A1-th embodiment.
The flavored water of the present invention contains, as described above, a high-intensity sweetener in an amount corresponding to a sweetness intensity X1 and has a sweetness of a sweetness intensity X2 exhibited by the components (a) to (c) and 0.1<X1<X2 is satisfied.

The flavored water of the present invention has an enhanced sweetness as having been already mentioned. Whether or not the sweetness of the flavored water of the present invention is enhanced can be evaluated by panelists who received sensory trainings. Further, for the sweetness intensity of the flavored water of the present invention, each standard flavored water to be the sweetness standard is prepared with each of sucrose concentrations assigned as sweetness intensities 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, and 15 and panelists compare the sweetness of the flavored water of the present invention with the sweetness of such each standard flavored water thereby to measure the sweetness of the flavored water of the present invention. Note that such each standard flavored water having a sweetness intensity of 1, 2, . . . 15 is prepared by adding sucrose in such a way that a sucrose content is 1 g/100 g, 2 g/100 g, . . . 15 g/100 g to the flavored water to which sucrose is not added.
Furthermore, of such standard flavored water having a lower sweetness than the flavored water of the present invention in the above measurement, the standard flavored water having the closest sweetness to that of the flavored water of the present invention is selected and adjusted in such a way as to have the same sweetness as that of the flavored water of the present invention by adding sucrose to the selected standard flavored water, during which a sweetness intensity of the flavored water of the present invention can also be measured from a sucrose content in the adjusted standard flavored water.
Other examples of the method for measuring a sweetness of the flavored water of the present invention include a sweetness intensity rating using Visual Analogue Scale (VAS method). For the VAS method, literatures in The journal of Japanese Society of Stomatognathic Function (2014) 20 pp. 115-129 (“Construction of a Screening Test for Gustatory Function in Four Basic Tastes” by Toyota et al.) and the like can be referred. Specifically, in the measurement of sweetness intensity by the VAS method, for example, evaluators define sweetness intensities as “not sweet at all” at the lower end and “nothing is sweeter than this” at the upper end and, using a piece of paper on which a vertical line indicating the intensities of sweetness on the straight line, assess a sweetness intensity sensed at that time by showing a position on the straight line.

The components (a) to (c) can be in any combinations.
As shown in examples to be described later, the addition of the component (b) and the component (c) to the component (a) enables to provide a sweetness intensity X2, which is higher than the sweetness intensity X1 of the component (a) alone. That is, the sweetness of the component (a) can be enhanced by the components (b) and (c). For this reason, flavored water can be produced without using or with a reduced amount of highly caloric sucrose while maintaining the sweetness equal to flavored water containing sucrose. Thus, the design of new low-caloric flavored water is enabled. In the case of designing zero-calorie flavored water, a high-intensity sweetener having particularly good-taste quality such as rebaudioside D (hereinafter, rebaudioside is sometimes abbreviated as “Reb”) and rebaudioside M is used for the component (a) and D-allulose or erythritol is used as an additional sweet substance thereby to improve a sweetness with a low-concentration amino acid and low-concentration sodium. In the case of adjusting flavored water to be not zero calories but a low calorie, a caloric sweetener such as sucrose, glucose, fructose, or sorbitol can be contained as an additional sweet substance.

In a preferable embodiment of the present invention, the high-intensity sweetener is selected from a high-intensity sweetener having a good taste quality. As used herein, the “high-intensity sweetener having a good taste quality” means a high-intensity sweet substance having one or more taste qualities selected from, when compared with rebaudioside A (RebA), (1) less astringent taste, (2) less metallic taste, (3) less aftertaste of sweetness, and (4) less bitterness. Whether or not a certain sweet substance has the above taste quality is already known or can be determined based on a sensory evaluation. Nonrestrictive examples of the high-intensity sweetener having a good taste quality include RebD, RebM, a luo han guo extract, a mogroside (for example, mogroside V), thaumatin, brazzein or a combination thereof.
In an embodiment of the present invention, the high-intensity sweetener may be those naturally occurring in plants and the like or those artificially produced (for example, bioconversion or chemosynthesis) but is preferably a naturally occurring sweetener. As used herein, the “naturally occurring” does not mean that a high-intensity sweet substance contained in the flavored water of the present invention is a natural product but a high-intensity sweet substance contained in the flavored water of the present invention may be a product artificially (for example, by bioconversion) produced (non-naturally occurring product) as long as the same substance naturally occurs.
Nonrestrictive examples of the sweetener (a) include rebaudioside A (RebA), rebaudioside D (RebD), rebaudioside M (RebM), neohesperidin dihydrochalcone, glycyrrhizin, thaumatin, monellin, mogroside, rubusoside, curculin, mabinlin, brazzein, pentagin, phyllodulcin, hernandulcin, miraculin, Stevia rebaudiana plant-containing sweet components, Siraitia grosvenorii plant-containing sweet components, Glycyrrhiza glabra plant-containing sweet components, Rubus suavissimus S. Lee plant-containing sweet components, Hydrangea macrophylla var. thunbergii plant-containing sweet components, Sclerochiton ilicifolius plant-containing sweet components, Thaumataococcus daniellii Benth plant-containing sweet components, Dioscoreophyllum volkensii plant-containing sweet components, Curculigo latifolia plant-containing sweet components, Richardella dulcifica plant-containing sweet components, Pentadiplandra brazzeana plant-containing sweet components, Capparis masaikai plant-containing sweet components, Lippia dulcis plant-containing sweet components and derivatives thereof, and combinations thereof. In a specific embodiment, the sweetener (a) contains RebA, RebD, RebM, a mogroside (for example, mogroside V) or a combination thereof. In another specific embodiment, the sweetener (a) contains RebD, RebM, a mogroside (for example, mogroside V), thaumatin or a combination thereof. In a preferable embodiment of the present invention, a high-intensity sweetener having a good taste quality contains at least one selected from the group consisting of RebD, RebM, mogroside V, a luo han guo extract, and a combination thereof. In an embodiment of the present invention, the sweetener (a) consists essentially of a sweetener other than major components of Stevia sweeteners such as RebA and stevioside. As used herein, the “consists essentially of . . . ” means that the sweetener used in the present invention may contain major component(s) of Stevia sweeteners as long as the effects of the invention are not affected. For example, preferably 90% or more, more preferably 95% or more, or further preferably 98% or more of the sweetener (a) for use in the present invention consists of a sweetener other than RebA and stevioside.
RebA, RebD and RebM may be directly extracted from Stevia, or may be obtained by adding glucose to a compound having another structure, contained in a Stevia extract.
The Luo han guo extract as a sweetener is an extract of Luo han guo containing a sweet substance derived from Luo han guo, approved in various countries including Japan as a food additive and commercially available. Examples of the sweet substance derived from Luo han guo include mogroside V, mogroside IV, 11-oxo-mogroside V, and Siamenoside I.
Mogroside V is a kind of the major mogrol glycosides contained in Luo han guo and documented to have a good-quality sweetness property close to sucrose when compared with rebaudioside A. Mogroside V may be obtained from a luo han guo extract (for example, an alcohol extract of Luo han guo) by purification with chromatography or the like. Alternatively, mogroside V may be obtained by adding glucose to a compound having another structure, contained in a luo han guo extract.
The luo han guo extract preferably contains mogroside V and the ratio thereof is not limited and may be 10 wt % or more, 15 wt % or more, 20 wt % or more, 25 wt % or more, 30 wt % or more, 35 wt % or more, 40 wt % or more, 45 wt % or more, 50 wt % or more, 55 wt % or more, 60 wt % or more, 65 wt % or more, 70 wt % or more or 75 wt % or more, of the total dry weight of a luo han guo extract. The content of mogroside V can be determined by a known technique such as liquid chromatography. The luo han guo extract can be obtained by extracting a fruit of Luo han guo (Siraitia grosvenorii) with a suitable solvent (for example, an aqueous solvent such as water, an alcohol solvent such as ethanol or methanol, or a mixed solvent of an aqueous solvent and an alcohol solvent such as water-containing ethanol or water-containing methanol), and then optionally carrying out a treatment such as degreasing, purification, concentration, and drying.
Mogroside V may be one having a high purity, and may be, for example, one having a purity of 80% or more, 85% or more, 90% or more, 91% or more, 92% or more, 93% or more, 94% or more, 95% or more, 96% or more, 97% or more or 98% or more. Mogroside V obtained by purification of a luo han guo extract, of course, has a smaller amount of incorporation of a luo han guo extract component other than mogroside V, as it has a higher purity.
In other embodiments of the present invention, mogroside V may also be one having a lower purity, and may be, for example, one having a purity of 50% or more, 55% or more, 60% or more, 65% or more, 70% or more or 75% or more. For example, when the sweetness intensity of sucrose per unit concentration Brix 1 is defined as a degree of sweetness of 1, the calculated value of the degree of sweetness of Mog V having a purity of about 65% is about 175. In other embodiments of the present invention, a luo han guo extract containing about 30 wt % of Mog V may be used as the high-intensity sweetener, and, when the sweetness intensity of sucrose per unit concentration Brix 1 is defined as a degree of sweetness of 1, the calculated value of the degree of sweetness of the luo han guo extract is about 100.
The high-intensity sweetener is contained in an amount corresponding to a sweetness intensity X1, as described above. When the sweetness intensity of sucrose per unit concentration Brix 1 is defined as a degree of sweetness of 1, a degree of sweetness of rebaudioside D is about 225, a degree of sweetness of rebaudioside M is about 230, a degree of sweetness of rebaudioside B is about 325, a degree of sweetness of rebaudioside A is 200 to 300 (median value 250), a degree of sweetness of rebaudioside N is 200 to 250 (median value 225), a degree of sweetness of rebaudioside O is 200 to 250 (median value 225), a degree of sweetness of rebaudioside E is 70 to 80 (median value 75), a degree of sweetness of a luo han guo extract (containing 40% of Mog V) is about 130, a degree of sweetness of mogroside V is about 270, a degree of sweetness of thaumatin is 2,000, and a degree of sweetness of brazzein is 500 to 2000 (median value 1250). The numerical value obtained by multiplying these degrees of sweetness by a concentration (w/v % (considered to be the same as w/w % in the case of a beverage)) of the high-intensity sweetener in the flavored water is a sweetness intensity of the high-intensity sweetener. When X1 of such a sweetener is herein determined, the above degree of sweetness (median value when a numerical value range is shown) is used. A relative ratio of a degree of sweetness of each sweetener to a degree of sweetness of 1 of sucrose can be determined from, for example, a known sugar sweetness conversion table (for example, information “Beverage term dictionary”, page 11, Beverage Japan, Inc.). When a numerical range of a degree of sweetness is herein shown, a median value is adopted. Herein, in the case of a sweetener whose degree of sweetness is different with respect to each literature, a relative ratio of a degree of sweetness to a degree of sweetness of 1 of sucrose can be determined by a sensory test. Examples of such a sensory test include a method involving preparing samples where sucrose is added to pure water so that Brix is 3.0 to 5.0 by 0.5, and selecting a sample where sucrose is added, having a sweetness intensity equal to that of an aqueous solution having a predetermined concentration of a sweetener, among such samples.
In an embodiment of the present invention, the high-intensity sweetener comprises at least one selected from the group consisting of steviol glycoside, a luo han guo extract, mogrol glycoside, a Thaumataococcus daniellii Benth plant-containing sweet component, a Pentadiplandra brazzeana plant-containing sweet component, an artificial sweetener, and a combination thereof. In a preferable embodiment of the present invention, the high-intensity sweetener comprises at least one selected from the group consisting of rebaudioside A, rebaudioside B, rebaudioside C, rebaudioside D, rebaudioside E, rebaudioside F, rebaudioside I, rebaudioside J, rebaudioside K, rebaudioside M, rebaudioside N, rebaudioside O, rebaudioside Q, rebaudioside R, Dulcoside A, Dulcoside C, rubusoside, steviol monoside, steviol bioside, stevioside, a luo han guo extract, mogroside V, thaumatin, brazzein, aspartame, acesulfame K, sucralose, a Glycyrrhiza extract, saccharine, and a combination thereof.

As used herein, the threshold of amino acids means a detection threshold or a taste recognition threshold. The detection threshold means a minimum concentration at which the difference from water can be clearly identified but a type of the taste (for example, bitterness, sourness, and sweetness) does not have to be always recognized, and the taste recognition threshold means a minimum concentration at which a taste can be recognized (for example, Eur J Clin Nutr (2004) 58, 629-636). The threshold (detection threshold) of amino acids is organized by Susan S. Schiffman et al. in “Comparison of Taste Qualities and Thresholds of D- and L-Amino Acids”, Physiology & Behavior, Vol. 27, pp. 51-59 (1981). For example, a detection threshold of each amino acid is as follows: glycine (30.9 mM), L-threonine (25.7 mM), L-serine (20.9 mM), L-alanine (16.2 mM), L-proline (15.1 mM), L-glutamine (9.77 mM), L-isoleucine (7.41 mM), L-phenylalanine (6.61 mM), L-leucine (6.45 mM), L-valine (4.16 mM), L-methionine (3.72 mM), L-tryptophan (2.29 mM), L-asparagine (1.62 mM), L-histidine (1.23 mM), L-arginine (1.20 mM), L-lysine (0.708 mM), L-aspartic acid (0.182 mM), L-glutamic acid (0.063 mM), L-cysteine (0.063 mM). Additionally, the taste recognition threshold is known to be about 1.5 to 2 times the detection threshold (Yuki Yamauchi et al., “WHOLE MOUTH GUSTATORY TEST (PART1)—BASIC CONSIDERATIONS AND PRINCIPAL COMPONENT ANALYSIS—”, Journal of The Oto-Rhino-Laryngological Society of Japan, vol. 98 (1995) No. 1, p. 119-129, and Reiko Ohmori, “Comparisons of the taste sensitivity between three generations”, The bulletin of the Faculty of Education, Utsunomiya University, Section 1 (2013) Vol. 63 p. 201-210)).
In the present invention, it is preferable that a measured value be used as the taste recognition threshold of an amino acid. A taste recognition threshold of an amino acid can be determined by preparing amino acid-containing aqueous solutions in several concentration levels and tasting in the order from low concentrations to high concentrations to carry out a sensory test by which the taste can be sensed or not. A concentration at which a difference from water is detected is defined as a detection threshold and a concentration at which a taste is recognized is defined as a recognition threshold. For example, for an amino acid for which a theoretical value (a literature value) is already established, aqueous solutions in several concentration levels close to such a concentration are prepared and several persons who received sensory trainings carry out the test thereby to determine these thresholds. In the case of L-alanine, a detection threshold described in literatures is 16.2 mM and a theoretical recognition threshold calculated from such a detection threshold is 32.4 mM, and a sensory test using aqueous solutions in several levels selected from 5 mM, 10 mM, 15 mM, 20 mM, 25 mM, 30 mM, and 35 mM is carried out thereby to measure a recognition threshold. In an embodiment of the present invention, the taste recognition threshold of an amino acid means a taste recognition threshold in pure water. The taste recognition threshold in pure water means a minimum concentration at which such a taste can be recognized when only an amino acid is added to water without addition of any sweetener or the like.

The flavored water of the present invention may contain a sweetener other than the high-intensity sweetener of the component (a). In the present description, the “sweetener” means any substance or a substance group which causes a sweetness response. Sweeteners can be classified into carbohydrate sweeteners and non-carbohydrate sweeteners based on structural characteristics and also into low-intensity sweeteners and high-intensity sweeteners based on the degree of sweetness. Further, sweet substances can also be classified based on the energy (calorie) into caloric sweeteners and non-caloric sweeteners. Further, sweet substances can also be classified based on the availability into natural sweeteners and artificial sweeteners. Note that, when the flavored water comprises a fruit juice and the fruit juice contains a fruit-derived sweetener (fructose or the like), such a sweetener is also encompassed in the sweetener here described. Also when the flavored water contains an extract and the extract contains a sweetener, the above can apply.
The carbohydrate sweetener is not limited and examples include starch sugars such as sucrose, lactose, glucose, maltose, starch syrup, a high-fructose corn syrup, and fructose, sugar alcohols such as erythritol, sorbitol, mannitol, maltitol, xylitol, and palatinit, sucrose, palatinose, fructooligosaccharide, Coupling Sugar®, galactooligosaccharide, lactosucrose, raffinose, soyoligosaccharide, and honey. Further, the carbohydrate sweetener includes rare sugars.
The rare sugar refers to a monosaccharide that occurs in very small quantities in nature and derivatives thereof. For example, the rare sugar includes naturally occurring aldoses other than D-glucose, D-galactose, D-mannose, D-ribose, D-xylose, and L-arabinose, naturally occurring ketoses other than D-fructose, naturally occurring sugar alcohols other than D-sorbitol. Nonrestrictive examples of the rare sugar include ketoses such as D-tagatose, D-sorbose, D-allulose (D-psicose), L-fructose, L-allulose (L-psicose), L-tagatose, L-sorbose, aldoses such as altrose and D-allose, sugar alcohols such as xylitol, erythritol, and D-talitol.
The caloric sweetener typically means sweet substances having an energy of 4 kcal/g. An energy of a sweet substance is already known or can be determined by measuring a content by HPLC or the like and calculating by multiplying the content by an energy conversion factor, or measuring a heat of physical combustion using a calorie meter (for example, bomb calorimeter) and correcting the heat with a digestion-absorption rate, an excreted heat or the like. Nonrestrictive examples of the caloric sweetener include sucrose, lactose, glucose, maltose, starch syrup, a high-fructose corn syrup, fructose.
The non-caloric sweeteners typically refer to those having the nature of being difficult to be digested in the body and consequently having a reduced energy to be taken into and mean sweet substances having an energy of less than 2 kcal/g, preferably less than 1 kcal/g, and further preferably less than 0.5 kcal/g. Nonrestrictive examples of the non-caloric sweetener include non-caloric hexoses such as allulose (psicose) and allose, non-caloric pentoses such as xylose and arabinose, non-caloric tetroses such as erythrose and threose, and non-caloric sugar alcohols such as erythritol and allitol.
Further, the sweet substances can also be classified based on the energy (calorie) level. For example, the sweet substances can be classified into sweet substances having an energy of 4 kcal/g or more and sweet substances having an energy of less than 4 kcal/g. The sweet substance having an energy of less than 4 kcal/g can further be classified into sweet substances having an energy of less than 3 kcal/g, sweet substances having an energy of less than 2.5 kcal/g, sweet substances having an energy of less than 2 kcal/g, sweet substances having an energy of less than 1.5 kcal/g, sweet substances having an energy of less than 1 kcal/g, sweet substances having an energy of less than 0.5 kcal/g, sweet substances having an energy of 1 kcal/g or more and less than 4 kcal/g, sweet substances having an energy of 2 kcal/g or more and less than 4 kcal/g, sweet substances having an energy of 3 kcal/g or more and less than 4 kcal/g, sweet substances having an energy of 2 kcal/g or more and less than 3 kcal/g, sweet substances having an energy of 1 kcal/g or more and less than 2 kcal/g, sweet substances having an energy of 0 kcal/g or more and less than 2 kcal/g, and sweet substances having an energy of 0 kcal/g or more and less than 1 kcal/g. Examples of the sweet substance having an energy of 4 kcal/g or more include sucrose, lactose, glucose, maltose, starch syrup, a high-fructose corn syrup, and fructose, examples of the sweet substance having an energy of 2 kcal/g or more and less than 4 kcal/g include sorbitol, xylitol, D-xylose, D-ribose, D-tagatose, and arabinose, and examples of the sweet substance having an energy of 0 kcal/g or more and less than 2 kcal/g include D-allulose, erythritol, allose, erythrose, threose, and allitol.
The low-intensity sweetener means a compound having about the same degree of sweetness as that of sucrose (for example, less than 5 times, about 0.1 to 2 times, about 0.5 to 1.5 times that of sucrose). Nonrestrictive examples of the low-intensity sweetener include low-intensity sugar sweeteners such as sucrose, a high-fructose corn syrup, glucose, fructose, lactose, maltose, xylose, lactulose, fructooligosaccharides, maltooligosaccharides, isomaltooligosaccharides, galactooligosaccharides, Coupling Sugar®, and palatinose, sugar alcohol low-intensity sweeteners such as maltitol, sorbitol, erythritol, xylitol, lactitol, palatinit, reduced starch saccharified products. Further, the low-intensity sweetener includes rare sugars, caloric sweeteners, non-caloric sweeteners, carbohydrate sweeteners, non-carbohydrate sweeteners, natural sweeteners, and artificial sweeteners as long as the degree of sweetness is in the above range.

1-2. Sparkling Beverage with an Enhanced Sweetness
The present invention provides, as the C1-th embodiment, the following sparkling beverage (hereinafter also referred to as “the sparkling beverage C of the present invention”).
A sparkling beverage comprising:
In other words, in the sparkling beverage of the C1-th embodiment of the present invention, the component having a sweetness is (a) a high-intensity sweetener in an amount corresponding to a sweetness intensity Xa, and the sweetness of the sparkling beverage of the present invention is supposed to be a sweetness intensity Xa when calculated. However, the presence of (b) an amino acid or a derivative or a salt thereof in an amount less than a taste recognition threshold, in the sparkling beverage even in a low concentration enhances the sweetness of (a) a high-intensity sweetener in an amount corresponding to a sweetness intensity Xa, to a sweetness intensity Xb (0.1<Xa<Xb is satisfied herein). The present invention means to possibly include, in addition to these components (a) and (b), further a sweetener other than (a); and optional components, for example, other components such as an acidulant, a flavor, a vitamin, a coloring, an antioxidant, an emulsifier, a preservative, a seasoning agent, an extract, a pH adjuster, a quality stabilizer, a fruit juice, a plant extract, a milk content, and caffeine. The sparkling beverage in an embodiment of the present invention does not contain a substance having a sweetness, as a sweetener, other than the component (a).
Furthermore, the sparkling beverage in a preferable embodiment of the present invention exerts the effect of improving a taste, other than enhancing a sweetness. For example, in the sparkling beverage in an embodiment of the present invention, at least one of “total sweetness”, “reduced aftertaste of sweetness”, “body, thickness”, “flavor intensity”, “reduced unpleasant tastes (bitterness, astringency, and the like)”, “saltiness” and “carbonic acid feeling” is preferably improved.
In the present invention, the “sparkling beverage” is a beverage from which bubbles are generated, and encompasses, for example, a beverage which, when poured into a container, allows a bubble layer to be formed on a liquid surface of the beverage. Examples of the sparkling beverage of the present invention include a carbonated beverage. The carbonated beverage is a beverage containing a carbon dioxide gas, and such a carbon dioxide gas encompasses a carbon dioxide gas separately injected into the beverage, and a carbon dioxide gas generated by fermentation of some of raw materials. The carbonated beverage is not particularly limited, and examples thereof include soft beverages, non-alcoholic beverages, and alcoholic beverages. Specific examples include sparkly beverages, colas, diet colas, ginger ales, ciders, fruit juice flavor carbonated beverages, and carbonated water to which fruit juice flavors are imparted, but not limited thereto.
The gas pressure of the sparkling beverage of the present invention is not particularly limited, and can be 2.2 to 4.0 kgf/cm2, 2.2 to 3.5 kgf/cm2, 2.2 to 3.3 kgf/cm2, 2.2 to 3.2 kgf/cm2, 2.3 to 4.0 kgf/cm2, 2.3 to 3.5 kgf/cm2, 2.3 to 3.2 kgf/cm2, 3.0 to 4.0 kgf/cm2, or 3.0 to 3.5 kgf/cm2. The content of gas in the sparkling beverage can be determined by the gas pressure. As used herein, the “gas pressure” refers to, unless particularly noted, the gas pressure of a carbon dioxide gas in the sparkling beverage in a container. The gas pressure can be measured by fixing the beverage at a liquid temperature of 20° C., to a gas internal pressure meter, once draining a carbon dioxide gas in a headspace by atmospheric relief with opening of a stopper cock of the gas internal pressure meter and then closing again the stopper cock, and reading a value at which an indicator reaches a certain position during shaking and moving of the gas internal pressure meter. The gas pressure of the sparkling beverage is herein measured with the above method, unless particularly described.
The sparkling beverage of the present invention may contain an alcohol. The alcoholic beverage refers to an alcohol-containing beverage, and the alcohol as mentioned herein means ethyl alcohol (ethanol), unless particularly noted. The alcoholic beverage according to the present invention is not limited in terms of type thereof as long as it contains any alcohol. The alcoholic beverage may be a beverage having an alcohol content of 0.05 to 40 v/v %, such as a beer, a sparkling liquor, chuhai, highball, or a cocktail, or may be a beverage having an alcohol content of less than 0.05 v/v %, such as a non-alcoholic beer, a chuhai taste beverage, or a soft beverage. The sparkling beverage of the present invention preferably has an alcohol content of less than 0.05 v/v %, further preferably 0.00 v/v %. As used herein, the alcohol content is expressed by a percentage based on volume/volume (v/v %). The alcohol content in the beverage can be measured by any known method, and can be measured with, for example, an oscillating densitometer.
The flavor of the sparkling beverage of the present invention is not particularly limited, and may be adjusted to various flavors. For example, the sparkling beverage of the present invention may be an orange-flavored, lemon-flavored, lime-flavored, grape-flavored, ginger ale-flavored, energy drink-flavored, blackcurrant-flavored or cola-flavored beverage. The flavor of the sparkling beverage of the present invention can be adjusted by adding a component which is approved as a food additive such as a fruit juice, an acidulant, a flavor, a plant extract, a milk content, and other flavor, or which, even if not approved, has been eaten since early times and is commonly recognized to be safe. In an embodiment of the present invention, the sparkling beverage of the present invention is not a beer taste beverage.
The sparkling beverage of the present invention may be a jelly beverage.
The form of the sparkling beverage of the present invention is not limited, and may be, for example, a sparkling beverage form packed in a container, which is contained and packed in a container such as a may, a bottle or a PET bottle.
As used herein, the “sweetness intensity” means an intensity of sweetness of a substance. For example, when the sweetness intensity of sucrose per unit concentration Brix 1 is defined as a degree of sweetness of 1, a degree of sweetness of glucose is 0.6 to 0.7 (median value 0.65). A numerical value obtained by multiplying this degree of sweetness by a concentration Brix value of glucose is the sweetness intensity of glucose. Thus, when a concentration of glucose is Brix 1.5, the sweetness intensity of glucose is 0.65×1.5=0.975. The degrees of sweetness of common sweeteners are as shown in Table 1 described with respect to the A1-th embodiment.

The sparkling beverage of the present invention has an enhanced sweetness as having been already mentioned. Whether or not the sweetness of the sparkling beverage of the present invention is enhanced can be evaluated by panelists who received sensory trainings. Further, for the sweetness intensity of the sparkling beverage of the present invention, standard sparkling beverages to be the sweetness standards are prepared with sucrose concentrations assigned as sweetness intensities 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, and 15 and panelists compare the sweetness of the sparkling beverage of the present invention with the sweetnesses of these standard sparkling beverages thereby to measure the sweetness of the sparkling beverage of the present invention. Note that the standard sparkling beverages having a sweetness intensity of 1, 2, . . . 15 are prepared by adding sucrose in such a way that a sucrose content is 1 g/100 g, 2 g/100 g, . . . 15 g/100 g to the sparkling beverage to which sucrose is not added.
Furthermore, of the standard sparkling beverages having a lower sweetness than the sparkling beverage of the present invention in the above measurement, the standard sparkling beverage having the closest sweetness to that of the sparkling beverage of the present invention is selected and adjusted in such a way as to have the same sweetness as that of the sparkling beverage of the present invention by adding sucrose to the selected standard sparkling beverage, during which a sweetness intensity of the sparkling beverage of the present invention can also be measured from a sucrose content in the adjusted standard sparkling beverage.
Other examples of the method for measuring a sweetness of the sparkling beverage of the present invention include a sweetness intensity rating using Visual Analogue Scale (VAS method). For the VAS method, literatures in The journal of Japanese Society of Stomatognathic Function (2014) 20 pp. 115-129 (“Construction of a Screening Test for Gustatory Function in Four Basic Tastes” by Toyota et al.) and the like can be referred. Specifically, in the measurement of sweetness intensity by the VAS method, for example, evaluators define sweetness intensities as “not sweet at all” at the lower end and “nothing is sweeter than this” at the upper end and, using a piece of paper on which a vertical line indicating the intensities of sweetness on the straight line, assess a sweetness intensity sensed at that time by showing a position on the straight line.

Further, an energy (total energy, TE) of the sparkling beverage of the present invention may be, depending on an embodiment (for example, an embodiment containing a caloric sweetener), 0<TE≤50 Kcal/100 ml, 0<TE≤45 Kcal/100 ml, 0<TE≤40 Kcal/100 ml, 0<TE 35 Kcal/100 ml, 0<TE 30 Kcal/100 ml, 0<TE≤24 Kcal/100 ml, 0<TE≤22 Kcal/100 ml, 0<TE≤20 Kcal/100 ml, 0<TE≤15 Kcal/100 ml, 0<TE≤10 Kcal/100 ml or 0<TE≤5 Kcal/100 ml (that is, it never is completely 0)
The components (a) and (b) can be in any combinations. As shown in examples to be described later, the addition of the component (b) to the component (a) enables to provide a sweetness intensity Xb, which is higher than the sweetness intensity Xa of the component (a) alone. That is, the sweetness of the component (a) can be enhanced by the component (b). For this reason, sparkling beverages can be produced without using or with a reduced amount of highly caloric sucrose while maintaining the sweetness equal to a sparkling beverage containing sucrose. Thus, the design of new low-caloric sparkling beverages is enabled. In the case of designing a zero-calorie sparkling beverage, a high-intensity sweetener having particularly good-taste quality such as rebaudioside D (hereinafter, rebaudioside is sometimes abbreviated as “Reb”) and rebaudioside M is used for the component (a) and D-allulose or erythritol is used as an additional sweet substance thereby to improve a sweetness with a low-concentration amino acid. In the case of adjusting a food to be not zero calories but a low calorie, a caloric sweetener such as sucrose, glucose, fructose, or sorbitol can be contained as an additional sweet substance.
The high-intensity sweetener (hereinafter, sometimes abbreviated as the “sweetener (a)!” or “component (a)!”) means a compound having a more intense sweetness than sucrose and encompasses naturally occurring compounds, synthetic compounds, and combinations of naturally occurring compounds and synthetic compounds. The high-intensity sweetener has, in the same amount as sucrose, a sweetness 5 times or more, 10 times or more, 50 times or more, 100 times or more, 500 times or more, 1,000 times or more, 5,000 times or more, 10,000 times or more, 50,000 times or more, or 100,000 times or more, of that of sucrose.
Specific examples of the high-intensity sweetener include peptide-based sweeteners such as aspartame, neotame, and advantame; sucrose derivatives such as sucralose; synthetic sweeteners (including those naturally occurring but also those whose synthetic products are mostly distributed such as neohesperidin dihydrochalcone) such as acesulfame K, saccharine, saccharin sodium, sodium cyclamate, dulcin, disodium glycyrrhizin, trisodium glycyrrhizin, and neohesperidin dihydrochalcone; sweeteners extracted from plants such as thaumatin, monellin, curculin, mabinlin, brazzein, pentagin, hernandulcin, 4β-hydroxyhernandulcin, miraculin, glycyrrhizin, rubusoside, and phyllodulcin; and plant extracts containing a high-intensity sweetener component, for example, Stevia rebaudiana extract, Siraitia grosvenorii (Luo han guo) extract, Glycyrrhiza (licorice) glabra extract, Rubus suavissimus S.

In a preferable embodiment of the present invention, the high-intensity sweetener is selected from a high-intensity sweetener having a good taste quality. As used herein, the “high-intensity sweetener having a good taste quality” means a high-intensity sweet substance having one or more taste qualities selected from, when compared with rebaudioside A (RebA), (1) less astringent taste, (2) less metallic taste, (3) less aftertaste of sweetness, and (4) less bitterness. Whether or not a certain sweet substance has the above taste quality is already known or can be determined based on a sensory evaluation. Nonrestrictive examples of the high-intensity sweetener having a good taste quality include RebD, RebM, a luo han guo extract, mogroside (for example, mogroside V), thaumatin, brazzein or a combination thereof.
In an embodiment of the present invention, the high-intensity sweetener may be those naturally occurring in plants and the like or those artificially produced (for example, bioconversion or chemosynthesis) but is preferably a naturally occurring sweetener. As used herein, the “naturally occurring” does not mean that a high-intensity sweet substance contained in the sparkling beverage of the present invention is a natural product but a high-intensity sweet substance contained in the sparkling beverage of the present invention may be a product artificially (for example, by bioconversion) produced (non-naturally occurring product) as long as the same substance naturally occurs.
Nonrestrictive examples of the sweetener (a) include rebaudioside A (RebA), rebaudioside D (RebD), rebaudioside M (RebM), neohesperidin dihydrochalcone, glycyrrhizin, thaumatin, monellin, mogroside, rubusoside, curculin, mabinlin, brazzein, pentagin, phyllodulcin, hernandulcin, miraculin, Stevia rebaudiana plant-containing sweet components, Siraitia grosvenorii plant-containing sweet components, Glycyrrhiza glabra plant-containing sweet components, Rubus suavissimus S. Lee plant-containing sweet components, Hydrangea macrophylla var. thunbergii plant-containing sweet components, Sclerochiton ilicifolius plant-containing sweet components, Thaumataococcus daniellii Benth plant-containing sweet components, Dioscoreophyllum volkensii plant-containing sweet components, Curculigo latifolia plant-containing sweet components, Richardella dulcifica plant-containing sweet components, Pentadiplandra brazzeana plant-containing sweet components, Capparis masaikai plant-containing sweet components, Lippia dulcis plant-containing sweet components and derivatives thereof, and combinations thereof. In a specific embodiment, the sweetener (a) contains RebA, RebD, RebM, a mogroside (for example, mogroside V) or a combination thereof. In another specific embodiment, the sweetener (a) contains RebA, RebD, RebM, a mogroside (for example, mogroside V), thaumatin or a combination thereof. In a preferable embodiment of the present invention, a high-intensity sweetener contains at least one selected from the group consisting of RebA, RebD, RebM, mogroside V, a luo han guo extract, and a combination thereof. In an embodiment of the present invention, the sweetener (a) consists essentially of a sweetener other than major components of Stevia sweeteners such as RebA, stevioside. As used herein, the “consists essentially of . . . ” means that the sweetener used in the present invention may contain major component(s) of Stevia sweeteners as long as the effects of the invention are not affected. For example, preferably 90% or more, more preferably 95% or more, or further preferably 98% or more of the sweetener (a) for use in the present invention consists of a sweetener other than RebA and stevioside.
RebA, RebD and RebM may be directly extracted from Stevia, or may be obtained by adding glucose to a compound having another structure, contained in a Stevia extract.
The Luo han guo extract as a sweetener is an extract of Luo han guo containing a sweet substance derived from Luo han guo, approved in various countries including Japan as a food additive and commercially available. Examples of the sweet substance derived from Luo han guo include mogroside V, mogroside IV, 11-oxo-mogroside V, and Siamenoside I.
Mogroside V is a kind of the major mogrol glycosides contained in Luo han guo and documented to have a good-quality sweetness property close to sucrose when compared with rebaudioside A. Mogroside V may be obtained from a luo han guo extract (for example, an alcohol extract of Luo han guo) by purification with chromatography or the like. Alternatively, mogroside V may be obtained by adding glucose to a compound having another structure, contained in a luo han guo extract.
The luo han guo extract preferably contains mogroside V and the ratio thereof is not limited and may be 10 wt % or more, 15 wt % or more, 20 wt % or more, 25 wt % or more, 30 wt % or more, 35 wt % or more, 40 wt % or more, 45 wt % or more, 50 wt % or more, 55 wt % or more, 60 wt % or more, 65 wt % or more, 70 wt % or more or 75 wt % or more, of the total dry weight of a luo han guo extract. The content of mogroside V can be determined by a known technique such as liquid chromatography. The luo han guo extract can be obtained by extracting a fruit of Luo han guo (Siraitia grosvenorii) with a suitable solvent (for example, an aqueous solvent such as water, an alcohol solvent such as ethanol or methanol, or a mixed solvent of an aqueous solvent and an alcohol solvent such as water-containing ethanol or water-containing methanol), and then optionally carrying out a treatment such as degreasing, purification, concentration, and drying.
Mogroside V may be one having a high purity, and may be, for example, one having a purity of 80% or more, 85% or more, 90% or more, 91% or more, 92% or more, 93% or more, 94% or more, 95% or more, 96% or more, 97% or more or 98% or more. Mogroside V obtained by purification of a luo han guo extract, of course, has a smaller amount of incorporation of a luo han guo extract component other than mogroside V, as it has a higher purity.
In other embodiments of the present invention, mogroside V may also be one having a lower purity, and may be, for example, one having a purity of 50% or more, 55% or more, 60% or more, 65% or more, 70% or more or 75% or more. For example, when the sweetness intensity of sucrose per unit concentration Brix 1 is defined as a degree of sweetness of 1, the calculated value of the degree of sweetness of Mog V having a purity of about 65% is about 175. In other embodiments of the present invention, a luo han guo extract containing about 30 wt % of Mog V may be used as the high-intensity sweetener, and, when the sweetness intensity of sucrose per unit concentration Brix 1 is defined as a degree of sweetness of 1, the calculated value of the degree of sweetness of the luo han guo extract is about 100.
The high-intensity sweetener is contained in an amount corresponding to a sweetness intensity Xa, as described above. When the sweetness intensity of sucrose per unit concentration Brix 1 is defined as a degree of sweetness of 1, a degree of sweetness of rebaudioside D is about 225, a degree of sweetness of rebaudioside M is about 230, a degree of sweetness of rebaudioside B is about 325, a degree of sweetness of rebaudioside A is 200 to 300 (median value 250), a degree of sweetness of rebaudioside N is 200 to 250 (median value 225), a degree of sweetness of rebaudioside O is 200 to 250 (median value 225), a degree of sweetness of rebaudioside E is 70 to 80 (median value 75), a degree of sweetness of a luo han guo extract (containing 40% of Mog V) is about 130, a degree of sweetness of mogroside V is about 270, a degree of sweetness of thaumatin is 2,000, and a degree of sweetness of brazzein is 500 to 2000 (median value 1250). The numerical value obtained by multiplying these degrees of sweetness by a concentration (w/v % (considered to be the same as w/w % in the case of a beverage)) of the high-intensity sweetener in the sparkling beverage is a sweetness intensity of the high-intensity sweetener. When Xa of such a sweetener is herein determined, the above degree of sweetness (median value when a numerical value range is shown) is used. A relative ratio of a degree of sweetness of each sweetener to a degree of sweetness of 1 of sucrose can be determined from, for example, a known sugar sweetness conversion table (for example, information “Beverage term dictionary”, page 11, Beverage Japan, Inc.). When a numerical range of a degree of sweetness is herein shown, a median value is adopted. Herein, in the case of a sweetener whose degree of sweetness is different with respect to each literature, a relative ratio of a degree of sweetness to a degree of sweetness of 1 of sucrose can be determined by a sensory test. Examples of such a sensory test include a method involving preparing samples where sucrose is added to pure water so that Brix is 3.0 to 5.0 by 0.5, and selecting a sample where sucrose is added, having a sweetness intensity equal to that of an aqueous solution having a predetermined concentration of a sweetener, among such samples.
In an embodiment of the present invention, the high-intensity sweetener comprises at least one selected from the group consisting of steviol glycoside, a luo han guo extract, mogrol glycoside, a Thaumataococcus daniellii Benth plant-containing sweet component, a Pentadiplandra brazzeana plant-containing sweet component, an artificial sweetener, and a combination thereof.

As used herein, the threshold of amino acids means a detection threshold or a taste recognition threshold. The detection threshold means a minimum concentration at which the difference from water can be clearly identified but a type of the taste (for example, bitterness, sourness, and sweetness) does not have to be always recognized, and the taste recognition threshold means a minimum concentration at which a taste can be recognized (for example, Eur J Clin Nutr (2004) 58, 629-636). The threshold (detection threshold) of amino acids is organized by Susan S. Schiffman et al. in “Comparison of Taste Qualities and Thresholds of D- and L-Amino Acids”, Physiology & Behavior, Vol. 27, pp. 51-59 (1981). For example, a detection threshold of each amino acid is as follows: glycine (30.9 mM), L-threonine (25.7 mM), L-serine (20.9 mM), L-alanine (16.2 mM), L-proline (15.1 mM), L-glutamine (9.77 mM), L-isoleucine (7.41 mM), L-phenylalanine (6.61 mM), L-leucine (6.45 mM), L-valine (4.16 mM), L-methionine (3.72 mM), L-tryptophan (2.29 mM), L-asparagine (1.62 mM)), L-histidine (1.23 mM)), L-arginine (1.20 mM)), L-lysine (0.708 mM)), L-aspartic acid (0.182 mM), L-glutamic acid (0.063 mM), L-cysteine (0.063 mM). Additionally, the taste recognition threshold is known to be about 1.5 to 2 times the detection threshold (Yuki Yamauchi et al., “WHOLE MOUTH GUSTATORY TEST (PART1)—BASIC CONSIDERATIONS AND PRINCIPAL COMPONENT ANALYSIS—”, Journal of The Oto-Rhino-Laryngological Society of Japan, vol. 98 (1995) No. 1, p. 119-129, and Reiko Ohmori, “Comparisons of the taste sensitivity between three generations”, The bulletin of the Faculty of Education, Utsunomiya University, Section 1 (2013) Vol. 63 p. 201-210)).
In the present invention, it is preferable that a measured value be used as the taste recognition threshold of an amino acid. A taste recognition threshold of an amino acid can be determined by preparing amino acid-containing aqueous solutions in several concentration levels and tasting in the order from low concentrations to high concentrations to carry out a sensory test by which the taste can be sensed or not. A concentration at which a difference from water is detected is defined as a detection threshold and a concentration at which a taste is recognized is defined as a recognition threshold. For example, for an amino acid for which a theoretical value (a literature value) is already established, aqueous solutions in several concentration levels close to such a concentration are prepared and several persons who received sensory trainings carry out the test thereby to determine these thresholds. In the case of L-alanine, a detection threshold described in literatures is 16.2 mM and a theoretical recognition threshold calculated from such a detection threshold is 32.4 mM, and a sensory test using aqueous solutions in several levels selected from 5 mM, 10 mM, 15 mM, 20 mM, 25 mM, 30 mM, and 35 mM is carried out thereby to measure a recognition threshold. In an embodiment of the present invention, the taste recognition threshold of an amino acid means a taste recognition threshold in pure water. The taste recognition threshold in pure water means a minimum concentration at which such a taste can be recognized when only an amino acid is added to water without addition of any sweetener or the like.

The sparkling beverage of the present invention may contain a sweetener other than the high-intensity sweetener of the component (a). In the present description, the “sweetener” means any substance or a substance group which causes a sweetness response. Sweeteners can be classified into carbohydrate sweeteners and non-carbohydrate sweeteners based on structural characteristics and also into low-intensity sweeteners and high-intensity sweeteners based on the degree of sweetness. Further, sweet substances can also be classified based on the energy (calorie) into caloric sweeteners and non-caloric sweeteners. Further, sweet substances can also be classified based on the availability into natural sweeteners and artificial sweeteners. Note that, when other components including sweeteners such as fruit juices and milk contents are contained, such sweeteners are also encompassed in the sweeteners here described.
The carbohydrate sweetener is not limited and examples include starch sugars such as sucrose, lactose, glucose, maltose, starch syrup, a high-fructose corn syrup, and fructose, sugar alcohols such as erythritol, sorbitol, mannitol, maltitol, xylitol, and palatinit, sucrose, palatinose, fructooligosaccharide, Coupling Sugar®, galactooligosaccharide, lactosucrose, raffinose, soyoligosaccharide, and honey. Further, the carbohydrate sweetener includes rare sugars.
The rare sugar refers to a monosaccharide that occurs in very small quantities in nature and derivatives thereof. For example, the rare sugar includes naturally occurring aldoses other than D-glucose, D-galactose, D-mannose, D-ribose, D-xylose, and L-arabinose, naturally occurring ketoses other than D-fructose, and naturally occurring sugar alcohols other than D-sorbitol. Nonrestrictive examples of the rare sugar include ketoses such as D-tagatose, D-sorbose, D-allulose (D-psicose), L-fructose, L-allulose (L-psicose), L-tagatose, and L-sorbose, aldoses such as altrose and D-allose, and sugar alcohols such as xylitol, erythritol, and D-talitol.
The caloric sweetener typically means sweet substances having an energy of 4 kcal/g. An energy of a sweet substance is already known or can be determined by measuring a content by HPLC or the like and calculating by multiplying the content by an energy conversion factor, or measuring a heat of physical combustion using a calorie meter (for example, bomb calorimeter) and correcting the heat with a digestion-absorption rate, an excreted heat or the like. Nonrestrictive examples of the caloric sweetener include sucrose, lactose, glucose, maltose, starch syrup, a high-fructose corn syrup, fructose.
The non-caloric sweeteners typically refer to those having the nature of being difficult to be digested in the body and consequently having a reduced energy to be taken into and mean sweet substances having an energy of less than 2 kcal/g, preferably less than 1 kcal/g, and further preferably less than 0.5 kcal/g. Nonrestrictive examples of the non-caloric sweetener include non-caloric hexoses such as allulose (psicose) and allose, non-caloric pentoses such as xylose and arabinose, non-caloric tetroses such as erythrose and threose, and non-caloric sugar alcohols such as erythritol and allitol.
Further, the sweet substances can also be classified based on the energy (calorie) level. For example, the sweet substances can be classified into sweet substances having an energy of 4 kcal/g or more and sweet substances having an energy of less than 4 kcal/g. The sweet substance having an energy of less than 4 kcal/g may further be classified into sweet substances having an energy of less than 3 kcal/g, sweet substances having an energy of less than 2.5 kcal/g, sweet substances having an energy of less than 2 kcal/g, sweet substances having an energy of less than 1.5 kcal/g, sweet substances having an energy of less than 1 kcal/g, sweet substances having an energy of less than 0.5 kcal/g, sweet substances having an energy of 1 kcal/g or more and less than 4 kcal/g, sweet substances having an energy of 2 kcal/g or more and less than 4 kcal/g, sweet substances having an energy of 3 kcal/g or more and less than 4 kcal/g, sweet substances having an energy of 2 kcal/g or more and less than 3 kcal/g, sweet substances having an energy of 1 kcal/g or more and less than 2 kcal/g, sweet substances having an energy of 0 kcal/g or more and less than 2 kcal/g, and sweet substances having an energy of 0 kcal/g or more and less than 1 kcal/g. Examples of the sweet substance having an energy of 4 kcal/g or more include sucrose, lactose, glucose, maltose, starch syrup, a high-fructose corn syrup, and fructose, examples of the sweet substance having an energy of 2 kcal/g or more and less than 4 kcal/g include sorbitol, xylitol, D-xylose, D-ribose, D-tagatose, and arabinose, and examples of the sweet substance having an energy of 0 kcal/g or more and less than 2 kcal/g include D-allulose, erythritol, allose, erythrose, threose, and allitol.
The low-intensity sweetener means a compound having about the same degree of sweetness as that of sucrose (for example, less than 5 times, about 0.1 to 2 times, about 0.5 to 1.5 times that of sucrose). Nonrestrictive examples of the low-intensity sweetener include low-intensity sugar sweeteners such as sucrose, a high-fructose corn syrup, glucose, fructose, lactose, maltose, xylose, lactulose, fructooligosaccharide, maltooligosaccharide, isomaltooligosaccharide, galactooligosaccharide, Coupling Sugar®, and palatinose, and sugar alcohol low-intensity sweeteners such as maltitol, sorbitol, erythritol, xylitol, lactitol, palatinit, and reduced starch saccharified products. Further, the low-intensity sweetener includes rare sugars, caloric sweeteners, non-caloric sweeteners, carbohydrate sweeteners, non-carbohydrate sweeteners, natural sweeteners, and artificial sweeteners as long as the degree of sweetness is in the above range.

The present invention provides, as the D1-th embodiment, the following sparkling beverage (hereinafter also referred to as “the sparkling beverage D of the present invention”).
A sparkling beverage comprising:
In other words, in the sparkling beverage of the D1-th embodiment of the present invention, the component having a sweetness is (a) a high-intensity sweetener in an amount corresponding to a sweetness intensity X1, and the sweetness of the sparkling beverage of the present invention is supposed to be a sweetness intensity X1 when calculated. However, the presence of (b) an amino acid or a derivative or a salt thereof in an amount less than a taste recognition threshold and (c) 6 to 60 mg/100 ml of sodium, in the sparkling beverage even in low concentrations enhances the sweetness of (a) a high-intensity sweetener in an amount corresponding to a sweetness intensity X1, to a sweetness intensity X2 (0.1<X1<X2 is satisfied herein). The present invention means to possibly include, in addition to these components (a) to (c), further a sweetener other than (a); and optional components, for example, other components such as an acidulant, a flavor, a vitamin, a coloring, an antioxidant, an emulsifier, a preservative, a seasoning agent, an extract, a pH adjuster, a quality stabilizer, a fruit juice, a plant extract, a milk content, and caffeine. The sparkling beverage in an embodiment of the present invention does not contain a substance having a sweetness, as a sweetener, other than the component (a).
Furthermore, the sparkling beverage in a preferable embodiment of the present invention exerts the effect of improving a taste, other than enhancing a sweetness. For example, in the sparkling beverage in an embodiment of the present invention, at least one of “total sweetness”, “reduced aftertaste of sweetness”, “body, thickness”, “flavor intensity”, “reduced unpleasant tastes (bitterness, astringency, and the like)”, “saltiness” and “carbonic acid feeling” is preferably improved. In a preferable embodiment of the present invention, “carbonic acid feeling” is made mild by a combination of alanine and sodium. “Body, thickness” is improved by a combination of serine or glycine and sodium.
In the present invention, the “sparkling beverage” is a beverage from which bubbles are generated, and encompasses, for example, a beverage which, when poured into a container, allows a bubble layer to be formed on a liquid surface of the beverage. Examples of the sparkling beverage of the present invention include a carbonated beverage. The carbonated beverage is a beverage containing a carbon dioxide gas, and such a carbon dioxide gas encompasses a carbon dioxide gas separately injected into the beverage, and a carbon dioxide gas generated by fermentation of some of raw materials. The carbonated beverage is not particularly limited, and examples thereof include soft beverages, non-alcoholic beverages, and alcoholic beverages. Specific examples include sparkly beverages, colas, diet colas, ginger ales, ciders, fruit juice flavor carbonated beverages, and carbonated water to which fruit juice flavors are imparted, but not limited thereto.
The gas pressure of the sparkling beverage of the present invention is not particularly limited, and can be 2.2 to 4.0 kgf/cm2, 2.2 to 3.5 kgf/cm2, 2.2 to 3.3 kgf/cm2, 2.2 to 3.2 kgf/cm2, 2.3 to 4.0 kgf/cm2, 2.3 to 3.5 kgf/cm2, 2.3 to 3.2 kgf/cm2, 3.0 to 4.0 kgf/cm2, or 3.0 to 3.5 kgf/cm2. The content of gas in the sparkling beverage can be determined by the gas pressure. As used herein, the “gas pressure” refers to, unless particularly noted, the gas pressure of a carbon dioxide gas in the sparkling beverage in a container. The gas pressure can be measured by fixing the beverage at a liquid temperature of 20° C., to a gas internal pressure meter, once draining a carbon dioxide gas in a headspace by atmospheric relief with opening of a stopper cock of the gas internal pressure meter and then closing again the stopper cock, and reading a value at which an indicator reaches a certain position during shaking and moving of the gas internal pressure meter. The gas pressure of the sparkling beverage is herein measured with the above method, unless particularly described.
The sparkling beverage of the present invention may contain an alcohol. The alcoholic beverage refers to an alcohol-containing beverage, and the alcohol as mentioned herein means ethyl alcohol (ethanol), unless particularly noted. The alcoholic beverage according to the present invention is not limited in terms of type thereof as long as it contains any alcohol. The alcoholic beverage may be a beverage having an alcohol content of 0.05 to 40 v/v %, such as a beer, a sparkling liquor, chuhai, highball, or a cocktail, or may be a beverage having an alcohol content of less than 0.05 v/v %, such as a non-alcoholic beer, a chuhai taste beverage, or a soft beverage. The sparkling beverage of the present invention preferably has an alcohol content of less than 0.05 v/v %, further preferably 0.00 v/v %. As used herein, the alcohol content is expressed by a percentage based on volume/volume (v/v %). The alcohol content in the beverage can be measured by any known method, and can be measured with, for example, an oscillating densitometer.
The flavor of the sparkling beverage of the present invention is not particularly limited, and can be adjusted to various flavors. For example, the sparkling beverage of the present invention may be an orange-flavored, lemon-flavored, lime-flavored, grape-flavored, ginger ale-flavored, energy drink-flavored, blackcurrant-flavored or cola-flavored beverage. The flavor of the sparkling beverage of the present invention can be adjusted by adding a component which is approved as a food additive such as a fruit juice, an acidulant, a flavor, a plant extract, a milk content, and other flavor, or which, even if not approved, has been eaten since early times and is commonly recognized to be safe. In an embodiment of the present invention, the sparkling beverage of the present invention is not a beer taste beverage.
The sparkling beverage of the present invention may be a jelly beverage.
The form of the sparkling beverage of the present invention is not limited, and may be, for example, a sparkling beverage form packed in a container, which is contained and packed in a container such as a may, a bottle or a PET bottle.
As used herein, the “sweetness intensity” means an intensity of sweetness of a substance. For example, when the sweetness intensity of sucrose per unit concentration Brix 1 is defined as a degree of sweetness of 1, a degree of sweetness of glucose is 0.6 to 0.7 (median value 0.65). A numerical value obtained by multiplying this degree of sweetness by a concentration Brix value of glucose is the sweetness intensity of glucose. Thus, when a concentration of glucose is Brix 1.5, the sweetness intensity of glucose is 0.65×1.5=0.975.

The sparkling beverage of the present invention has an enhanced sweetness as having been already mentioned. Whether or not the sweetness of the sparkling beverage of the present invention is enhanced can be evaluated by panelists who received sensory trainings. Further, for the sweetness intensity of the sparkling beverage of the present invention, standard sparkling beverages to be the sweetness standards are prepared with sucrose concentrations assigned as sweetness intensities 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, and 15 and panelists compare the sweetness of the sparkling beverage of the present invention with the sweetnesses of these standard sparkling beverages thereby to measure the sweetness of the sparkling beverage of the present invention. Note that the standard sparkling beverages having a sweetness intensity of 1, 2, . . . 15 are prepared by adding sucrose in such a way that a sucrose content is 1 g/100 g, 2 g/100 g, . . . 15 g/100 g to the sparkling beverage to which sucrose is not added.
Furthermore, of the standard sparkling beverages having a lower sweetness than the sparkling beverage of the present invention in the above measurement, the standard sparkling beverage having the closest sweetness to that of the sparkling beverage of the present invention is selected and adjusted in such a way as to have the same sweetness as that of the sparkling beverage of the present invention by adding sucrose to the selected standard sparkling beverage, during which a sweetness intensity of the sparkling beverage of the present invention can also be measured from a sucrose content in the adjusted standard sparkling beverage.
Other examples of the method for measuring a sweetness of the sparkling beverage of the present invention include a sweetness intensity rating using Visual Analogue Scale (VAS method). For the VAS method, literatures in The journal of Japanese Society of Stomatognathic Function (2014) 20 pp. 115-129 (“Construction of a Screening Test for Gustatory Function in Four Basic Tastes” by Toyota et al.) and the like can be referred. Specifically, in the measurement of sweetness intensity by the VAS method, for example, evaluators define sweetness intensities as “not sweet at all” at the lower end and “nothing is sweeter than this” at the upper end and, using a piece of paper on which a vertical line indicating the intensities of sweetness on the straight line, assess a sweetness intensity sensed at that time by showing a position on the straight line.
The sweetness intensity of the sparkling beverage of the present invention is not particularly limited as long as it is acceptable as a sparkling beverage and may be, in terms of the degree of sweetness, for example, 4.0 to 20, 4.0 to 15, 4.0 to 12.5, 4.0 to 10, 4.5 to 20, 4.5 to 15, 4.5 to 12.5, 4.5 to 10, 5.0 to 20, 5.0 to 15, 5.0 to 12.5, 5.0 to 10, 5.5 to 20, 5.5 to 15, 5.5 to 12.5, 5.5 to 10, 6.0 to 20, 6.0 to 15, 6.0 to 12.5, 6.0 to 10, 6.5 to 20, 6.5 to 15, 6.5 to 12.5, 6.5 to 10, 7.0 to 20, 7.0 to 15, 7.0 to 12.5, 7.0 to 10, 7.5 to 20, 7.5 to 15, 7.5 to 12.5, 7.5 to 10, 7.5 to 9, 7.5 to 8, 8.0 to 20, 8.0 to 20, 8.0 to 15, 8.0 to 12.5, 8.0 to 10, 8.5 to 20, 8.5 to 15, 8.5 to 12.5, 8.5 to 10, 9.0 to 20, 9.0 to 15, 9.0 to 12.5, 9.0 to 10, 9.5 to 20, 9.5 to 15, 9.5 to 12.5, 9.5 to 10, 10.0 to 20, 10.0 to 15, 10.0 to 12.5, 10.5 to 20, 10.5 to 15, or 10.5 to 12.5.

Further, an energy (total energy, TE) of the sparkling beverage of the present invention may be, depending on an embodiment (for example, an embodiment containing a caloric sweetener), 0<TE≤50 Kcal/100 ml, 0<TE≤45 Kcal/100 ml, 0<TE≤40 Kcal/100 ml, 0<TE 35 Kcal/100 ml, 0<TE 30 Kcal/100 ml, 0<TE≤24 Kcal/100 ml, 0<TE≤22 Kcal/100 ml, 0<TE≤20 Kcal/100 ml, 0<TE≤15 Kcal/100 ml, 0<TE≤10 Kcal/100 ml or 0<TE≤5 Kcal/100 ml (that is, it never is completely 0)
The components (a) to (c) can be in any combinations. As shown in examples to be described later, the addition of the component (b) and the component (c) to the component (a) enables to provide a sweetness intensity X2, which is higher than the sweetness intensity X1 of the component (a) alone. That is, the sweetness of the component (a) can be enhanced by the components (b) and (c). For this reason, sparkling beverages can be produced without using or with a reduced amount of highly caloric sucrose while maintaining the sweetness equal to a sparkling beverage containing sucrose. Thus, the design of new low-caloric sparkling beverages is enabled. In the case of designing a zero-calorie sparkling beverage, a high-intensity sweetener having particularly good-taste quality such as rebaudioside D (hereinafter, rebaudioside is sometimes abbreviated as “Reb”) and rebaudioside M is used for the component (a) and D-allulose or erythritol is used as an additional sweet substance thereby to improve a sweetness with a low-concentration amino acid and low-concentration sodium. In the case of adjusting a food to be not zero calories but a low calorie, a caloric sweetener such as sucrose, glucose, fructose, or sorbitol can be contained as an additional sweet substance.
The high-intensity sweetener (hereinafter, sometimes abbreviated as the “sweetener (a)!” or “component (a)!”) means a compound having a more intense sweetness than sucrose and encompasses naturally occurring compounds, synthetic compounds, and combinations of naturally occurring compounds and synthetic compounds. The high-intensity sweetener has, in the same amount as sucrose, a sweetness 5 times or more, 10 times or more, 50 times or more, 100 times or more, 500 times or more, 1,000 times or more, 5,000 times or more, 10,000 times or more, 50,000 times or more, or 100,000 times or more, of that of sucrose.
Specific examples of the high-intensity sweetener include peptide-based sweeteners such as aspartame, neotame, and advantame; sucrose derivatives such as sucralose; synthetic sweeteners (including those naturally occurring but also those whose synthetic products are mostly distributed such as neohesperidin dihydrochalcone) such as acesulfame K, saccharine, saccharin sodium, sodium cyclamate, dulcin, disodium glycyrrhizin, trisodium glycyrrhizin, and neohesperidin dihydrochalcone; sweeteners extracted from plants such as thaumatin, monellin, curculin, mabinlin, brazzein, pentagin, hernandulcin, 4β-hydroxyhernandulcin, miraculin, glycyrrhizin, rubusoside, and phyllodulcin; and plant extracts containing a high-intensity sweetener component, for example, Stevia rebaudiana extract, Siraitia grosvenorii (Luo han guo) extract, Glycyrrhiza (licorice) glabra extract, Rubus suavissimus S.

In a preferable embodiment of the present invention, the high-intensity sweetener is selected from a high-intensity sweetener having a good taste quality. As used herein, the “high-intensity sweetener having a good taste quality” means a high-intensity sweet substance having one or more taste qualities selected from, when compared with rebaudioside A (RebA), (1) less astringent taste, (2) less metallic taste, (3) less aftertaste of sweetness, and (4) less bitterness. Whether or not a certain sweet substance has the above taste quality is already known or may be determined based on a sensory evaluation. Nonrestrictive examples of the high-intensity sweetener having a good taste quality include RebD, RebM, a luo han guo extract, mogroside (for example, mogroside V), thaumatin, brazzein or a combination thereof.
In an embodiment of the present invention, the high-intensity sweetener may be those naturally occurring in plants and the like or those artificially produced (for example, bioconversion or chemosynthesis) but is preferably a naturally occurring sweetener. As used herein, the “naturally occurring” does not mean that a high-intensity sweet substance contained in the sparkling beverage of the present invention is a natural product but a high-intensity sweet substance contained in the sparkling beverage of the present invention may be a product artificially (for example, by bioconversion) produced (non-naturally occurring product) as long as the same substance naturally occurs.
Nonrestrictive examples of the sweetener (a) include rebaudioside A (RebA), rebaudioside D (RebD), rebaudioside M (RebM), neohesperidin dihydrochalcone, glycyrrhizin, thaumatin, monellin, mogroside, rubusoside, curculin, mabinlin, brazzein, pentagin, phyllodulcin, hernandulcin, miraculin, Stevia rebaudiana plant-containing sweet components, Siraitia grosvenorii plant-containing sweet components, Glycyrrhiza glabra plant-containing sweet components, Rubus suavissimus S. Lee plant-containing sweet components, Hydrangea macrophylla var. thunbergii plant-containing sweet components, Sclerochiton ilicifolius plant-containing sweet components, Thaumataococcus daniellii Benth plant-containing sweet components, Dioscoreophyllum volkensii plant-containing sweet components, Curculigo latifolia plant-containing sweet components, Richardella dulcifica plant-containing sweet components, Pentadiplandra brazzeana plant-containing sweet components, Capparis masaikai plant-containing sweet components, Lippia dulcis plant-containing sweet components and derivatives thereof, and combinations thereof. In a specific embodiment, the sweetener (a) contains RebA, RebD, RebM, a mogroside (for example, mogroside V) or a combination thereof. In another specific embodiment, the sweetener (a) contains RebA, RebD, RebM, mogroside (for example, mogroside V), thaumatin or a combination thereof. In a preferable embodiment of the present invention, a high-intensity sweetener contains at least one selected from the group consisting of RebA, RebD, RebM, mogroside V, a luo han guo extract, and a combination thereof. In an embodiment of the present invention, the sweetener (a) consists essentially of a sweetener other than major components of Stevia sweeteners such as RebA, stevioside. As used herein, the “consists essentially of . . . ” means that the sweetener used in the present invention may contain major component(s) of Stevia sweeteners as long as the effects of the invention are not affected. For example, preferably 90% or more, more preferably 95% or more, or further preferably 98% or more of the sweetener (a) for use in the present invention consists of a sweetener other than RebA and stevioside.
RebA, RebD and RebM may be directly extracted from Stevia, or may be obtained by adding glucose to a compound having another structure, contained in a Stevia extract.
The Luo han guo extract as a sweetener is an extract of Luo han guo containing a sweet substance derived from Luo han guo, approved in various countries including Japan as a food additive and commercially available. Examples of the sweet substance derived from Luo han guo include mogroside V, mogroside IV, 11-oxo-mogroside V, and Siamenoside I.
Mogroside V is a kind of the major mogrol glycosides contained in Luo han guo and documented to have a good-quality sweetness property close to sucrose when compared with rebaudioside A. Mogroside V can be obtained from a luo han guo extract (for example, an alcohol extract of Luo han guo) by purification with chromatography or the like. Alternatively, mogroside V may be obtained by adding glucose to a compound having another structure, contained in a luo han guo extract.
The luo han guo extract preferably contains mogroside V and the ratio thereof is not limited and may be 10 wt % or more, 15 wt % or more, 20 wt % or more, 25 wt % or more, 30 wt % or more, 35 wt % or more, 40 wt % or more, 45 wt % or more, 50 wt % or more, 55 wt % or more, 60 wt % or more, 65 wt % or more, 70 wt % or more or 75 wt % or more, of the total dry weight of a luo han guo extract. The content of mogroside V can be determined by a known technique such as liquid chromatography. The luo han guo extract can be obtained by extracting a fruit of Luo han guo (Siraitia grosvenorii) with a suitable solvent (for example, an aqueous solvent such as water, an alcohol solvent such as ethanol or methanol, or a mixed solvent of an aqueous solvent and an alcohol solvent such as water-containing ethanol or water-containing methanol), and then optionally carrying out a treatment such as degreasing, purification, concentration, and drying.
Mogroside V may be one having a high purity, and may be, for example, one having a purity of 80% or more, 85% or more, 90% or more, 91% or more, 92% or more, 93% or more, 94% or more, 95% or more, 96% or more, 97% or more or 98% or more. Mogroside V obtained by purification of a luo han guo extract, of course, has a smaller amount of incorporation of a luo han guo extract component other than mogroside V, as it has a higher purity.
In other embodiments of the present invention, mogroside V may also be one having a lower purity, and may be, for example, one having a purity of 50% or more, 55% or more, 60% or more, 65% or more, 70% or more or 75% or more. For example, when the sweetness intensity of sucrose per unit concentration Brix 1 is defined as a degree of sweetness of 1, the calculated value of the degree of sweetness of Mog V having a purity of about 65% is about 175. In other embodiments of the present invention, a luo han guo extract containing about 30 wt % of Mog V may be used as the high-intensity sweetener, and, when the sweetness intensity of sucrose per unit concentration Brix 1 is defined as a degree of sweetness of 1, the calculated value of the degree of sweetness of the luo han guo extract is about 100.
The high-intensity sweetener is contained in an amount corresponding to a sweetness intensity X1, as described above. When the sweetness intensity of sucrose per unit concentration Brix 1 is defined as a degree of sweetness of 1, a degree of sweetness of rebaudioside D is about 225, a degree of sweetness of rebaudioside M is about 230, a degree of sweetness of rebaudioside B is about 325, a degree of sweetness of rebaudioside A is 200 to 300 (median value 250), a degree of sweetness of rebaudioside N is 200 to 250 (median value 225), a degree of sweetness of rebaudioside O is 200 to 250 (median value 225), a degree of sweetness of rebaudioside E is 70 to 80 (median value 75), a degree of sweetness of a luo han guo extract (containing 40% of Mog V) is about 130, a degree of sweetness of mogroside V is about 270, a degree of sweetness of thaumatin is 2,000, and a degree of sweetness of brazzein is 500 to 2000 (median value 1250). The numerical value obtained by multiplying these degrees of sweetness by a concentration (w/v % (considered to be the same as w/w % in the case of a beverage)) of the high-intensity sweetener in the sparkling beverage is a sweetness intensity of the high-intensity sweetener. When X1 of such a sweetener is herein determined, the above degree of sweetness (median value when a numerical value range is shown) is used. A relative ratio of a degree of sweetness of each sweetener to a degree of sweetness of 1 of sucrose can be determined from, for example, a known sugar sweetness conversion table (for example, information “Beverage term dictionary”, page 11, Beverage Japan, Inc.). When a numerical range of a degree of sweetness is herein shown, a median value is adopted. Herein, in the case of a sweetener whose degree of sweetness is different with respect to each literature, a relative ratio of a degree of sweetness to a degree of sweetness of 1 of sucrose can be determined by a sensory test. Examples of such a sensory test include a method involving preparing samples where sucrose is added to pure water so that Brix is 3.0 to 5.0 by 0.5, and selecting a sample where sucrose is added, having a sweetness intensity equal to that of an aqueous solution having a predetermined concentration of a sweetener, among such samples.

As used herein, the threshold of amino acids means a detection threshold or a taste recognition threshold. The detection threshold means a minimum concentration at which the difference from water may be clearly identified but a type of the taste (for example, bitterness, sourness, and sweetness) does not have to be always recognized, and the taste recognition threshold means a minimum concentration at which a taste can be recognized (for example, Eur J Clin Nutr (2004) 58, 629-636). The threshold (detection threshold) of amino acids is organized by Susan S. Schiffman et al. in “Comparison of Taste Qualities and Thresholds of D- and L-Amino Acids”, Physiology & Behavior, Vol. 27, pp. 51-59 (1981). For example, a detection threshold of each amino acid is as follows: glycine (30.9 mM), L-threonine (25.7 mM), L-serine (20.9 mM), L-alanine (16.2 mM), L-proline (15.1 mM), L-glutamine (9.77 mM), L-isoleucine (7.41 mM), L-phenylalanine (6.61 mM), L-leucine (6.45 mM), L-valine (4.16 mM), L-methionine (3.72 mM), L-tryptophan (2.29 mM), L-asparagine (1.62 mM), L-histidine (1.23 mM), L-arginine (1. 20 mM), L-lysine (0.708 mM), L-aspartic acid (0.182 mM), L-glutamic acid (0.063 mM), L-cysteine (0.063 mM). Additionally, the taste recognition threshold is known to be about 1.5 to 2 times the detection threshold (Yuki Yamauchi et al., “WHOLE MOUTH GUSTATORY TEST (PART1)—BASIC CONSIDERATIONS AND PRINCIPAL COMPONENT ANALYSIS—”, Journal of The Oto-Rhino-Laryngological Society of Japan, vol. 98 (1995) No. 1, p. 119-129, and Reiko Ohmori, “Comparisons of the taste sensitivity between three generations”, The bulletin of the Faculty of Education, Utsunomiya University, Section 1 (2013) Vol. 63 p. 201-210)).
In the present invention, it is preferable that a measured value be used as the taste recognition threshold of an amino acid. A taste recognition threshold of an amino acid can be determined by preparing amino acid-containing aqueous solutions in several concentration levels and tasting in the order from low concentrations to high concentrations to carry out a sensory test by which the taste can be sensed or not. A concentration at which a difference from water is detected is defined as a detection threshold and a concentration at which a taste is recognized is defined as a recognition threshold. For example, for an amino acid for which a theoretical value (a literature value) is already established, aqueous solutions in several concentration levels close to such a concentration are prepared and several persons who received sensory trainings carry out the test thereby to determine these thresholds. In the case of L-alanine, a detection threshold described in literatures is 16.2 mM and a theoretical recognition threshold calculated from such a detection threshold is 32.4 mM, and a sensory test using aqueous solutions in several levels selected from 5 mM, 10 mM, 15 mM, 20 mM, 25 mM, 30 mM, and 35 mM is carried out thereby to measure a recognition threshold. In an embodiment of the present invention, the taste recognition threshold of an amino acid means a taste recognition threshold in pure water. The taste recognition threshold in pure water means a minimum concentration at which such a taste can be recognized when only an amino acid is added to water without addition of any sweetener or the like.

The sparkling beverage of the present invention may contain a sweetener other than the high-intensity sweetener of the component (a). In the present description, the “sweetener” means any substance or a substance group which causes a sweetness response. Sweeteners can be classified into carbohydrate sweeteners and non-carbohydrate sweeteners based on structural characteristics and also into low-intensity sweeteners and high-intensity sweeteners based on the degree of sweetness. Further, sweet substances can also be classified based on the energy (calorie) into caloric sweeteners and non-caloric sweeteners. Further, sweet substances can also be classified based on the availability into natural sweeteners and artificial sweeteners. Note that, when other components including sweeteners such as fruit juices and milk contents are contained, such sweeteners are also encompassed in the sweeteners here described.
The carbohydrate sweetener is not limited and examples include starch sugars such as sucrose, lactose, glucose, maltose, starch syrup, a high-fructose corn syrup, and fructose, sugar alcohols such as erythritol, sorbitol, mannitol, maltitol, xylitol, and palatinit, sucrose, palatinose, fructooligosaccharide, Coupling Sugar®, galactooligosaccharide, lactosucrose, raffinose, soyoligosaccharide, and honey. Further, the carbohydrate sweetener includes rare sugars.
The rare sugar refers to a monosaccharide that occurs in very small quantities in nature and derivatives thereof. For example, the rare sugar includes naturally occurring aldoses other than D-glucose, D-galactose, D-mannose, D-ribose, D-xylose, and L-arabinose, naturally occurring ketoses other than D-fructose, and naturally occurring sugar alcohols other than D-sorbitol. Nonrestrictive examples of the rare sugar include ketoses such as D-tagatose, D-sorbose, D-allulose (D-psicose), L-fructose, L-allulose (L-psicose), L-tagatose, and L-sorbose, aldoses such as altrose and D-allose, and sugar alcohols such as xylitol, erythritol, and D-talitol.
The caloric sweetener typically means sweet substances having an energy of 4 kcal/g. An energy of a sweet substance is already known or can be determined by measuring a content by HPLC or the like and calculating by multiplying the content by an energy conversion factor, or measuring a heat of physical combustion using a calorie meter (for example, bomb calorimeter) and correcting the heat with a digestion-absorption rate, an excreted heat or the like. Nonrestrictive examples of the caloric sweetener include sucrose, lactose, glucose, maltose, starch syrup, a high-fructose corn syrup, fructose.
The non-caloric sweeteners typically refer to those having the nature of being difficult to be digested in the body and consequently having a reduced energy to be taken into and mean sweet substances having an energy of less than 2 kcal/g, preferably less than 1 kcal/g, and further preferably less than 0.5 kcal/g. Nonrestrictive examples of the non-caloric sweetener include non-caloric hexoses such as allulose (psicose) and allose, non-caloric pentoses such as xylose and arabinose, non-caloric tetroses such as erythrose and threose, and non-caloric sugar alcohols such as erythritol and allitol.
Further, the sweet substances can also be classified based on the energy (calorie) level. For example, the sweet substances can be classified into sweet substances having an energy of 4 kcal/g or more and sweet substances having an energy of less than 4 kcal/g. The sweet substance having an energy of less than 4 kcal/g can further be classified into sweet substances having an energy of less than 3 kcal/g, sweet substances having an energy of less than 2.5 kcal/g, sweet substances having an energy of less than 2 kcal/g, sweet substances having an energy of less than 1.5 kcal/g, sweet substances having an energy of less than 1 kcal/g, sweet substances having an energy of less than 0.5 kcal/g, sweet substances having an energy of 1 kcal/g or more and less than 4 kcal/g, sweet substances having an energy of 2 kcal/g or more and less than 4 kcal/g, sweet substances having an energy of 3 kcal/g or more and less than 4 kcal/g, sweet substances having an energy of 2 kcal/g or more and less than 3 kcal/g, sweet substances having an energy of 1 kcal/g or more and less than 2 kcal/g, sweet substances having an energy of 0 kcal/g or more and less than 2 kcal/g, and sweet substances having an energy of 0 kcal/g or more and less than 1 kcal/g. Examples of the sweet substance having an energy of 4 kcal/g or more include sucrose, lactose, glucose, maltose, starch syrup, a high-fructose corn syrup, and fructose, examples of the sweet substance having an energy of 2 kcal/g or more and less than 4 kcal/g include sorbitol, xylitol, D-xylose, D-ribose, D-tagatose, and arabinose, and examples of the sweet substance having an energy of 0 kcal/g or more and less than 2 kcal/g include D-allulose, erythritol, allose, erythrose, threose, and allitol.
The low-intensity sweetener means a compound having about the same degree of sweetness as that of sucrose (for example, less than 5 times, about 0.1 to 2 times, about 0.5 to 1.5 times that of sucrose). Nonrestrictive examples of the low-intensity sweetener include low-intensity sugar sweeteners such as sucrose, a high-fructose corn syrup, glucose, fructose, lactose, maltose, xylose, lactulose, fructooligosaccharide, maltooligosaccharide, isomaltooligosaccharide, galactooligosaccharide, Coupling Sugar®, and palatinose, and sugar alcohol low-intensity sweeteners such as maltitol, sorbitol, erythritol, xylitol, lactitol, palatinit, and reduced starch saccharified products. Further, the low-intensity sweetener includes rare sugars, caloric sweeteners, non-caloric sweeteners, carbohydrate sweeteners, non-carbohydrate sweeteners, natural sweeteners, and artificial sweeteners as long as the degree of sweetness is in the above range.

2-1. Method for Producing Flavored Water
The present invention provides, as the A2-th embodiment, the following method for producing flavored water with an enhanced sweetness (hereinafter also referred to as “the production method A of the present invention”).
A method for producing flavored water of the present invention, comprising, to a raw material,
The flavored water produced by the method of the present invention is the flavored water A of the present invention described in the above section “1-1. Flavored water with an enhanced sweetness.” Additionally, the “raw material” in the production method A of the present invention may be each material or a mixture thereof required for the production of the flavored water, and may further include any components such as a preservative, a flavor, a carrier. The “raw material” may be made up of several materials.
In the production method of the present invention, any of the following (a) and (b) may be carried out first.
Two steps may be carried out simultaneously. For example, (a) and (b) may be carried out simultaneously.
In Step (a), a high-intensity sweetener in an amount corresponding to a sweetness intensity Xa is added to the raw material but a high-intensity sweetener in an amount corresponding to a sweetness intensity Xa does not need to be added at once but may be added in several divided batches.
Similarly, when an amino acid of less than a taste recognition threshold is added in Step (b), the amino acid of less than a taste recognition threshold does not need to be added at once but may be added in several divided batches. The amino acid or a derivative thereof, or a salt thereof, added to the raw material in Step (b) may be selected from the amino acids or derivatives thereof, or salts thereof described in the A1-th embodiment of the above section “1-1. Flavored water with an enhanced sweetness.”

In the present description, the “mM” means a molar concentration and means 1×10−3 mol/L.
Hereinafter, the present invention will be specifically described in reference with examples but the present invention is not limited to the following examples.
Aqueous solutions of DL-alanine (purity 98% or more), L-serine (purity 98.5% or more), glycine (purity 98.5% or more), L-arginine (purity 98.5% or more), L-glutamic acid (purity 99% or more), L-valine (purity 98% or more) and L-glutamine (purity 98% or more) at the concentrations shown in Table 1 below were prepared with pure water. Each of the samples contained only water and the amino acid. These samples were evaluated by those (5 to 6 persons) who received sensory trainings as panelists using the criteria below.
Evaluation Criteria
The evaluation results are shown in Table 2 below.
Based on the results in the above table, a taste recognition threshold of each of the amino acids was calculated based on the concentration at which a half or more of the sensory testers sensed as “Taste is sensed” and shown in Table 3 below.
Several amino acids or salts thereof were actually measured for the taste recognition threshold by the same method as in Reference Example 1. Aqueous solutions of L-leucine (purity 98.0% or more), L-threonine (purity 98.0% or more), L-proline (purity 98.0% or more), L-asparagine (purity 99.0% or more) and L-lysine hydrochloride (purity 98.0% or more) at the concentrations shown in Table 4 below were prepared with pure water. Each of the samples contained only water and the amino acid. These samples were evaluated by those (6 to 7 persons) who received sensory trainings as panelists using the criteria below.
The evaluation results are shown in Table 4 below.
Based on the results in the above table, a taste recognition threshold of each of the amino acids was calculated based on the concentration at which a half or more of the sensory testers sensed as “Taste is sensed” and shown in Table 5 below.
Hereinafter, examples for evaluation on a taste quality improvement effect of the flavored water by an amino acid or an amino acid and sodium will be shown.
First, a measurement method of an amino acid is shown.
Seventeen amino acids of arginine, lysine, histidine, phenylalanine, tyrosine, leucine, isoleucine, valine, alanine, glycine, proline, glutamic acid, serine, threonine, aspartic acid, cystine and methionine were extracted by addition of a 10% sulfosalicylic acid solution to a sample, then a 3 mol/l sodium hydroxide solution was added to adjust a pH to 2.2, then a sodium citrate buffer (pH 2.2) was added for volume fixation, the resultant was subjected to filtration and thereafter appropriate dilution, and thus a test solution was adjusted. The test solution can be measured under the following two conditions, depending on a dilution factor and a type of an amino acid to be measured.
Condition 1
Condition 2
A test solution for tryptophan was adjusted in the same manner as in the above seventeen types, adjusted by an aqueous 3 mol/l sodium hydroxide solution so as to be slightly alkaline, subjected to volume fixation, and thereafter measured with high-performance liquid chromatography (LC-20AD, manufactured by Shimadzu Corporation). Measurement conditions were as follows.
Natural sugar {sucrose (manufactured by Pacific Sugar Mfg. Co., Ltd.), glucose (manufactured by Showa Sangyo Co., Ltd.)}, rebaudioside D (RebD) (purity 95% or more), sodium gluconate (purity 98% or more) and DL-alanine (purity 98% or more) were dissolved in sugar-free orange or peach-flavored water (sodium content: 0 (mg/100 ml), energy: 0 (kcal/100 ml)) in the ratios shown in Tables 6 and 7 below to prepare beverage samples (absorbance at a wavelength of 660 nm: 0.01 or less, ΔE value of transmitted light: 3.5 or less). The sugar-free orange or peach-flavored water contained an orange or peach flavor. A lemon-concentrated fruit juice and an acidulant were also added to the sugar-free orange or peach-flavored water. Further, Examples A1 and B1 were control samples to which neither alanine, nor sodium was added. In the present example and subsequent Example 2, a sodium content contained in a beverage serving as a base was measured by atomic absorption spectrometry with SpectrAA240FS (manufactured by Agilent Technologies Japan, Ltd.).
Contents of amino acids (eighteen amino acids of arginine, lysine, histidine, phenylalanine, tyrosine, leucine, isoleucine, valine, alanine, glycine, proline, glutamic acid, serine, threonine, aspartic acid, cystine, methionine and tryptophan) contained in a lemon-concentrated fruit juice used in a beverage base were calculated based on measurement values determined by measuring amino acids contained in a concentrated fruit juice before dilution, in an analytical institution by use of an amino acid automatic analysis method (in the case of tryptophan, high-performance liquid chromatography) under the above conditions. Contents of the above eighteen amino acids contained in the lemon-concentrated fruit juice were each less than 1.0 mg/100 g.
A content of sodium in each beverage in Tables 6 and 7 was measured by atomic absorption spectrometry with SpectrAA240FS (manufactured by Agilent Technologies Japan, Ltd.), a content of alanine was measured in an analytical institution by use of an amino acid automatic analysis method according to a known method, and an energy (kcal/100 ml) was calculated under the assumption that an energy of each component derived from an acidulant, a flavor, RebD and sodium was 0 (kcal/100 ml). Brix (amount of soluble solid) was calculated by determining a refractive index of a specimen with a digital refractometer manufactured by Atago Co., Ltd., and performing conversion into wt % of a sucrose liquid corresponding to the value.
A sweetness intensity of a low-intensity sweetener satisfies 1 (sucrose content (Brix))+3.5 (glucose content (Brix))×0.65 (coefficient of degree of sweetness of glucose to sucrose)=3.275, and a sweetness intensity of RebD satisfies 0.0208×225=4.68. Thus, sweetness intensities of an orange-flavored water and a peach-flavored water, to which Na and an amino acid were not added, were each 7.955.

2)a lower limit of quantitation of less than 1.0 mg/100 g.
The taste quality improvement effect by alanine or alanine and sodium was verified by the sensory comparison of taste qualities of these beverage samples. The taste qualities as sensory evaluation items were “total sweetness”, “reduced aftertaste of sweetness”, “body, thickness”, “flavor intensity”, “reduced unpleasant tastes (bitterness, astringency, and the like)!” and “saltiness”, and were verified by those (4 persons) who received sensory trainings as panelists. Further, sterilization was appropriately carried out before the sensory evaluation.
First, the “sensory evaluation score” with respect to each taste quality of each beverage sample was calculated based on the common taste quality determination criteria possessed by panelists due to routine trainings.
The “sensory evaluation score” is obtained by numerical conversion of the difference in taste quality from a control sample in a range from −3.0 to +3.0 under the assumption that the degrees of taste qualities in Example A1 and Example B1 (control samples for each flavored water sample) are each “0” (standard). The criteria of “sensory evaluation score” with respect to each item are as follows.
In view of the above criteria, for example, when a taste quality was determined to be rated between “+1.0” and “+2.0”, scoring was made by 0.5, for example, “+1.5”. For example, a higher score of “total sweetness” means a stronger sweetness, a higher score of “reduced aftertaste of sweetness” means a more suppressed aftertaste of sweetness, a higher score of “body, thickness” means increased body and thickness, a higher score of “flavor intensity” means a stronger flavor, a higher score of “reduced unpleasant tastes (bitterness, astringency, and the like)” means more suppressed unpleasant tastes, and a lower store of “saltiness” means more suppressed saltiness.
