The present invention relates to flavor in edible compositions.
There is an increasing demand worldwide to have broader available choices of reduced sugar content in foods and beverages, whether for taste preference, lifestyle reasons or for certain individuals (e.g., diabetic patients) for health-related goals. Accordingly, health benefits associated with the reduction of sugar content in foods and beverages is desirable. The use of non-caloric artificial and natural high-potency sweeteners to reduce the level of sweeteners such as caloric and non-caloric sweeteners in foods is limited due to temporal and/or flavor issues, e.g., slow onset of sweetness, sweetness linger, bitter, metallic or licorice taste. It is, therefore, desirable to provide compounds that may be added to food products, consumer products and pharmaceuticals which allow for the use of reduced amounts of caloric sweeteners (e.g., sugars) while maintaining desirable sweet taste and avoiding the flavor issues associated with sugar substitutes.
The present disclosure provides compounds that enhance sweet taste, edible compositions comprising such compounds, and methods of preparing such edible compositions. The present disclosure also provides methods of reducing the amount of a sweetener in an edible composition. The present disclosure further provides a method of enhancing, modulating or potentiating the sweet taste of an edible composition, such as a food, consumer or pharmaceutical product, in a subject. The present disclosure also provides a method of modulating, particularly enhancing or potentiating the activation of a sweet taste receptor. A further aspect of the present disclosure provides compounds, or mixtures thereof for masking or reducing unpleasant taste sensations, in particular for masking or reducing the bitter taste sensation of a bitter-tastant.
One aspect of the present disclosure provides compounds for modulating sweet taste (e.g., enhancing sweet taste) of a sweet tastant. In some embodiments, the compound is a flavonoid compound. In some embodiments, the flavonoid is a flavan. In some embodiments, the flavonoid compound has a molecular weight less than about 1000, 500, or 300 Daltons. In certain embodiments, the flavonoid compound is a compound of Formula (I), comestibly or biologically acceptable salts or derivatives thereof, enantiomers thereof, or combinations thereof. In certain embodiments, the flavonoid compound is any one of Compounds 1-6 or combinations thereof, or comestibly or biologically acceptable salts or derivatives thereof. The present disclosure also includes edible compositions comprising sweet taste modulating compounds such as the compounds of Formula (I). In addition, the present disclosure also includes edible compositions comprising sweet taste modulating compounds such as any one of Compounds 1-6, or combinations thereof.
Such taste modulators may be combined with any suitable sweetener, such as a natural caloric sweetener, a natural high-potency sweetener, a synthetic sweetener including a synthetic high-potency sweetener, sugar alcohols, rare sugars, sweetener enhancers or combinations thereof, to provide a composition having enhanced sweetness. In some embodiments, the compound of Formula (I), comestibly or biologically acceptable salts or derivatives thereof, or enantiomers thereof, or combinations thereof is present in the composition in an amount at or below its inherent sweetness threshold. In other embodiments, any one of Compounds 1-6 or combinations thereof, or comestibly or biologically acceptable salts or derivatives thereof is present in the composition in an amount at or below its inherent sweetness threshold. In embodiments wherein the compound is present in the composition in an amount at or below its inherent sweetness threshold, the compound does not act as a sweetener. The compositions may further comprise at least one sweet taste improving composition.

As defined herein, the compounds of the invention are intended to include all stereochemical forms of the compound, including geometric isomers (i.e., E, Z) and optical isomers (i.e., R, S, (+), (−)). Single stereochemical isomers as well as enantiomeric mixtures of the present compounds are within the scope of the invention and are specifically contemplated. Unless otherwise stated, formulas depicted herein are also meant to include compounds which differ only in the presence of one or more isotopically enriched atoms. For example, compounds having the present formulas except for the replacement of a hydrogen by a deuterium or tritium, or the replacement of a carbon by a 13C- or 14C-enriched carbon are within the scope of this invention.
One aspect of present invention provides edible compositions comprising a sweet taste modulator of the present invention, including food products, consumer products, and pharmaceutical compositions comprising said compounds, and methods of preparing a such compositions. The present invention also provides methods of reducing the amount of a sweetener in an edible composition, methods for reducing caloric intake, methods of enhancing or potentiating sweet taste of a sweetener, methods of blocking a bitter taste, methods of enhancing or potentiating the activity of a sweet taste receptor, and methods of synthesizing sweet taste modulators. The present invention also includes reducing the amount of a sweetener in an edible composition or diet by replacing an amount of sugar or the other sweetener with an amount of one or more compounds or one or more extracts containing compounds of the present invention.
According to one aspect, the invention provides compounds for modulating sweet taste (e.g., enhancing or potentiating the sweet taste of a sweetener).
The term “sweet flavor” or “sweet taste” refers to the taste elicited by, for example, sugars. Non-limiting examples of compositions eliciting a sweet flavor include glucose, sucrose, fructose, saccharin, cyclamate, aspartame, acesulfame potassium, sucralose, alitame, and neotame. The amount of sweet flavor or the sweetness of a composition can be determined by, e.g., taste testing.
As used herein, the term “sweet taste modulators” refers to flavor substances with taste modifying properties. Sweetness enhancers are understood to be a type of “sweet taste modulator” where perception of sweetness is increased in a manner not solely attributable to the inherent sweetness of the sweetness enhancer alone. The term “sweetness enhancer” is understood to include at least compositions capable of enhancing or intensifying the perception of sweet taste of sweetener compositions or sweetened compositions. The term “sweetness enhancer” is synonymous with the terms “sweet taste potentiator,” “sweetness potentiator,” “sweetness amplifier,” and “sweetness intensifier.” Generally, the sweet taste modulating compounds provided herein (which serve to enhance the perception of sweetness) may enhance or potentiate the sweet taste of sweeteners without providing any noticeable sweet taste by themselves at acceptable use levels; however, the sweetness enhancers may themselves provide sweet taste at concentrations above a sweetness threshold level. It is noted that the sweetness enhancers may be effective as enhancers even if present at concentrations above their sweetness threshold level. In such embodiments, there is major contribution of the sweetness enhancer to the sweetness of the composition via enhancement of the inherently sweet taste attributed to a sweetener, where the sweetener is also present in the composition. As used herein, the term “sweetness threshold level” is understood to include at least the concentration at which the sweetness is perceptible as sweet in the edible compositions. The sweetness threshold level varies for different edible compositions (e.g., in different matrices), and may be varied with respect to the individual perceiving the sweetness.
In all embodiments of the present invention, the sweet taste modulator(s) of the present invention is a different compound from any sweetener. Accordingly, although an ingredient may be characterized as both a sweet taste modulator and a sweetener, in all embodiments of the disclosure, the sweet taste modulator and the sweetener are different ingredients, i.e., the sweet taste modulator and the sweetener are not the same compound.
Each embodiment of the invention described herein may be taken alone or in combination with one or more other embodiments of the invention.
The present invention provides flavonoid compounds for modulating or potentiating the sweet taste of a sweetener. The flavonoid compounds of this invention are capable of modulating or potentiating the sweet taste of a sweetener. The flavonoid compound may have a molecular weight less than about 1000, 500, or 300 Daltons. The flavonoid compound may have a molecular weight less than 1000, 500, or 300 Daltons. In some embodiments, the flavonoid is a flavan. In certain embodiments, the flavonoid compound is a compound of Formula (I):
or a comestibly or biologically acceptable salt or derivative thereof, or an enantiomer thereof,
wherein, as valence and stability permit:
R1 to R6 are each independently H, OH, C1-C6 alkyl, or C1-C6 alkoxy, provided that at least one of R4 and R6 is not H.
In some embodiments of Formula (I),
R1 and R2 are each independently OH or OMe; and
R3-R6 are each independently H, OH, C1-C6 alkyl, or C1-C6 alkoxy,
provided that at least one of R4 and R6 is not H.
In some embodiments of Formula (I),
R1,R2, and R5 are each independently OH or OMe; and
R3,R4, and R6 are each independently H, OH, C1-C6 alkyl, or C1-C6 alkoxy,
provided that at least one of R4 and R6 is not H.
In some embodiments of Formula (I),
R1 and R2 are each independently OH or OMe;
R3, R4, and R6 are each independently H, OH, C1-C6 alkyl, or C1-C6 alkoxy,
provided that at least one of R4 and R6 is not H; and
R5 is OH.
In some embodiments of Formula (I),
R1 and R2 are each independently OH or OMe
R3 is H, OH, C1-C6 alkyl, or C1-C6 alkoxy;
R5 is OH; and
R4 and R6 are Me.
In some embodiments of Formula (I) the Compound is
or a comestibly or biologically acceptable salt or derivative thereof.
In some embodiments, the compound according to Formula (I) has the following structure:
In some embodiments, the compound according to Formula (I) has the following structure:
The terms “comestibly or biologically acceptable derivative” or “comestibly or biologically acceptable salt” refer to any comestibly or biologically acceptable derivative or salt of a sweet taste modulator of the present invention, which, upon ingestion, is capable of providing (directly or indirectly) a sweet taste modulator or bitter blocker of the present invention, or a polymorph, metabolite, residue or portion thereof, characterized by the ability to enhance the perception of a sweet taste attributed to a sweetener or block the perception of bitter taste attributed to a bitter tastant. A “comestible product” is a product suitable for oral use, such as eating or drinking. Therefore, a comestibly acceptable compound is an edible compound.
If a comestibly or biologically acceptable salt of a compound of the present invention is used, such salt is preferably derived from inorganic or organic bases. Salts derived from appropriate bases include alkali metal (e.g., sodium and potassium), alkaline earth metal (e.g., magnesium), ammonium and N+(C1-4alkyl)4 salts. In some embodiments, the compounds of the present invention are present as sodium or potassium salts.
Sweet taste modulators synergize with sweeteners to enhance or potentiate the perception of sweet taste due to the sweetener. When sweet taste modulators are used above their sweetness threshold level, they synergize with sweeteners to enhance or potentiate the perception of sweet taste due to the sweetener. In such cases, the overall sweetness of a composition comprising a sweet taste modulator and a sweet compound is higher than the mere addition of inherent sweetness due to each of the sweet taste modulators and a sweet compound. For example, if a sweet taste modulator with a sweetness equivalent to 1% sucrose is added to a 5% sucrose solution, the perceived sweetness of the resulting composition would be greater than that of a 6% sucrose solution—with any perceived sweetness greater than a 6% sucrose solution being attributable to the sweetness enhancing properties of the sweet taste modulators. Such an increase in perceived sweetness may be referred to as synergistic, not additive.
The terms “sweetness threshold,” and “sweetness recognition threshold,” are used interchangeably, herein, and refer to the level at which the lowest known concentration of a certain sweet compound is perceivable as sweet by the human sense of taste. This sweetness recognition threshold also encompasses the sweetness detection threshold, referring to the level at which the lowest known concentration of a certain sweet compound is perceivable by the human sense of taste. The sweetness threshold can vary from person to person. The sweetness threshold can also vary from matrix to matrix (e.g., different sweetness thresholds in water and a carbonated beverage). For example, a sweetness threshold level for sucrose in water could be around 1% or 1.5%. In some embodiments, the sweetness enhancers of Formula (I), any one of Compounds 1-6, or combinations thereof are used at concentrations below their sweetness threshold.
The terms “effective concentration” and “effective amount” are used interchangeably herein and refer to an amount sufficient to produce a desired property or result. For example, an effective amount of a sweet taste modulator of the present invention is an amount capable of modulating (e.g., enhancing) the perception of sweet taste associated with a sweetener. The term “effective amount” of a sweet taste modulator of the invention also refers to an amount which, when added to an edible composition, enhances the sweet taste of, e.g., a sugar, thereby allowing for the maintenance of the perception of a desired sweet flavor of the edible composition. The term “effective amount” also refers to the amount of a sweet taste modulator of the present invention capable of modulating (e.g., enhancing) the perception of a sweet taste associated with either a sweetener in a food product or an inherently sweet food product. The sweet taste modulators of the present invention may impart a sweetness or taste at certain concentrations and no perceptible sweetness or taste at other concentrations. For example, the sweet taste modulator may be present in an amount such that the taste, such as sweetness, of the sweet taste modulator is imperceptible. The compositions discussed herein include an effective amount of the sweet taste modulator. An effective amount of the sweet taste modulator includes an amount sufficient to enhance the perception of sweetness intensity of a sweetener.

The terms “parts per million” and “ppm” are used in the food industry to refer to a low concentration of a solution. For example, one gram of solute in 1000 ml of solvent has a concentration of 1000 ppm and one thousandth of a gram (0.001g) of solute in 1000 ml of solvent has a concentration of one ppm. Accordingly, a concentration of one milligram per liter (i.e., 1 mg/L) is equal to 1 ppm. A concentration of 1 mg % is 1 mg/100mL. Accordingly, a concentration of 1 mg % is equal to 10 ppm.
The sweet taste modulators of the invention may be combined with known naturally occurring and/or synthetic sweet taste modulators when used in embodiments (e.g., edible compositions and methods) described herein.

NHPS also includes modified NHPSs. Modified NHPSs include NHPSs which have been altered naturally. For example, a modified NHPS includes, but is not limited to, NHPSs which have been fermented, contacted with enzyme, or derivatized or substituted on the NHPS. In one embodiment, at least one modified NHPS may be used in combination with at least one NHPS. In another embodiment, at least one modified NHPS may be used without a NHPS. Thus, modified NHPSs may be substituted for a NHPS or may be used in combination with NHPSs for any of the embodiments described herein. For the sake of brevity, however, in the description of embodiments, a modified NHPS is not expressly described as an alternative to an unmodified NHPS, but it should be understood that modified NHPSs can be substituted for NHPSs in any embodiment disclosed herein.
In some embodiments, the sweetener may be used individually or in combination with other sweeteners. For example, the sweetener composition may comprise a single caloric sweetener, a single NHPS or a single synthetic sweetener; a single caloric sweetener with a single NHPS; a single caloric sweetener with a single synthetic sweetener; one or more caloric sweetener with a single NHPS; one or more caloric sweetener with a single synthetic sweetener; a single caloric sweetener with one or more NHPS; a single caloric sweetener with one or more synthetic sweeteners; a single NHPS in combination with a single synthetic sweetener; one or more NHPSs in combination with a single synthetic sweetener; a single NHPS in combination with one or more synthetic sweeteners; one or more NHPSs in combination with one or more synthetic sweeteners; or one or more caloric sweetener with one or more NHPS and one or more synthetic sweetener. A plurality of natural and/or synthetic sweeteners may be used as long as the combined effect does not adversely affect the taste of the sweetener composition or orally sweetened composition.
One of ordinary skill in the art should appreciate that the sweetener composition can be customized to obtain a desired calorie content. For example, a low-caloric or non-caloric synthetic sweetener may be combined with a caloric sweetener and/or other caloric additives to produce a sweetener composition with a preferred calorie content.
The sweetener is present in the composition in an amount greater than its sweetness threshold level. In some embodiments, the sweetener may be present in an amount ranging from 0.01% to 99.9% by weight, relative to the total weight of the composition. For example, the at least one sweetener may be present in an amount ranging from 2% to 50%, or for example from 4% to 50% by weight, relative to the total weight of the composition. In some embodiments, the at least one sweetener may be present in about 5% to 20% by weight. In further embodiments, the at least one sweetener may be present in about 5% to 15% by weight. In yet further embodiments, the at least one sweetener may be present in about 5% to 12% by weight in beverages, for example, in non-alcoholic beverages. In some embodiments, the at least one sweetener may be present in 5% to 20% by weight. In further embodiments, the at least one sweetener may be present in 5% to 15% by weight. In yet further embodiments, the at least one sweetener may be present in 5% to 12% by weight in beverages, for example, in non-alcoholic beverages.
In accordance with the disclosure, the sweet taste modulator of the present invention potentiates or enhances the sweetness of the sweetener. The composition comprising the sweetener and the sweet taste modulator of the present invention has more sweetness intensity than a composition comprising the at least one sweetener without the sweet taste modulator.
As used herein, the term “sweetness intensity” is understood to mean any perceptible sweetness. The composition comprising the sweetener and the sweet taste modulator of the present invention is perceptibly sweeter than a composition comprising the sweetener without the sweet taste modulator. For example, a composition comprising the sweetener and the sweet taste modulator of the present invention may be slightly sweeter, moderately sweeter, or significantly sweeter than a composition comprising the sweetener without the sweet taste modulator. As discussed above, in embodiments where the sweet taste modulators of Formula (I), any one of Compounds 1-6, or combinations thereof are used above their sweetness threshold, the increase in sweetness intensity is synergistic, not additive.
The sweetness of a composition may be based on (i.e., relative to) a known sweet standard. Sweet compounds based on such sweet standards include, but are not limited to, for example natural, non-natural, or synthetic sweeteners. Non-limiting examples of such sweeteners include caloric carbohydrate sweeteners, natural carbohydrate sweeteners, non-natural carbohydrate sweeteners, natural high-potency sweeteners, non-natural high-potency sweeteners, synthetic high potency sweeteners, synthetic carbohydrate sweeteners, and combinations thereof. For example, the sweetness of a composition may be based on to a 5% sucrose solution. In such cases, a composition comprising the sweetener and a sweet taste modulator of the present invention may be perceived as having a sweetness equivalent to a 5.5% sucrose solution. In other embodiments, the composition comprising the sweetener and a sweet taste modulator of the present invention may be perceived as having a sweetness equivalent to a 6.0%, 6.5%, 7.0%, 7.5%, 8.0%, 8.5%, 9.0%, 9.5%, or 10% sucrose solution. Suitable sweet standards include, but are not limited to, sucrose standards, fructose standards and glucose standards. Each of these standards may be used at concentrations which include, but are not limited to, 0.5%, 1.0%, 1.5%, 2.0%, 2.5%, 3.0%, 3.5%, 4.0%, 4.5%, 5.0%, 5.5%, 6.0%, 6.5%, 7.0%, 7.5%, 8.0%, 8.5%, 9.0%, 9.5%, or 10% solution. In some embodiments, the sweetness intensity of the composition comprising the sweetener and a sweet taste modulator of the present invention increases the perceived sweetness based on a sweet standard by greater than 10%, by greater than 20%, by greater than 30%, by greater than 40%, greater than by 50% or greater than by 60% compared to a composition comprising the sweetener without the sweet taste modulator.
In some embodiments, the perception of sweetness intensity of the sweetener (i.e., the perception of sweet taste of the sweetener in the edible composition) is enhanced by up to 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100%. In some embodiments, the perception of sweetness intensity of the sweetener is enhanced beyond 100%, for example, by 125%, 150%, 175%, 200%, 225%, 250%, 275%, 300%, 325%, 350%, 375%, 400%, 425%, 450%, 475%, 500% or increments in between those recited. In some embodiments, the perception of sweetness intensity is enhanced by up to 25%. In other embodiments, the perception of sweetness intensity is enhanced by up to 50%. In other embodiments, the perception of sweetness intensity is enhanced by up to 75%. In other embodiments, the sweetness intensity is enhanced by up to 100%. In some embodiments, the perception of sweetness intensity is enhanced by about 5-100%, 5-90%, 5-80%, 5-70%, 5-60%, 5-50%, 5-40%, 5-30%, 10-30%, 10-25%. 20-80%, 20-70%, 20-60%, 20-50%, 20-40%, 20-30%, 25-80%, 25-70%, 25-60%, 25-50%, 25-40%, or 25-30%. In some embodiments, the perception of sweetness intensity is enhanced by 5-100%, 5-90%, 5-80%, 5-70%, 5-60%, 5-50%, 5-40%, 5-30%, 10-30%, 10-25%. 20-80%, 20-70%, 20-60%, 20-50%, 20-40%, 20-30%, 25-80%, 25-70%, 25-60%, 25-50%, 25-40%, or 25-30%. These amounts are not meant to be limiting, and increments between the recited percentages are specifically envisioned as part of the invention.

The edible composition may comprise (i) a sweet taste modulator of the invention, or combinations thereof and (ii) a sweetener. In some embodiments, the sweet taste modulating compound is a flavonoid compound having a molecular weight less than about 1000, 500, or 300 Daltons. In some embodiments, the sweet taste modulating compound is a flavonoid compound having a molecular weight less than 1000, 500, or 300 Daltons. In certain embodiments, the sweet taste modulating compound is a compound of Formula (I), comestibly or biologically acceptable salts or derivatives thereof, enantiomers or diastereomers thereof, or combinations thereof. In other embodiments, the sweet taste modulating compound is a compound of any one of Compounds 1-6, or combinations thereof, or comestibly or biologically acceptable salts or derivatives thereof.
In some embodiments, the edible composition naturally or inherently comprises a sweetener. For example, the sweetener may be an inherent component of a food product or of a food stuff, such as fruit or a fruit product (e.g., fruit sauce). Accordingly, the compounds of the present invention may be added to edible compositions to which no sweetener is added.
In another embodiments, the edible composition is a sweetened composition comprising (i) a sweet taste modulator of the invention (e.g., a compound of Formula (I), any one of Compounds 1-6, or combinations thereof); and (ii) a sweetener.
In some embodiments, the compound of Formula (I), or any one of Compounds 1-6, or combinations thereof may be used to enhance the sweet taste or perception of any suitable natural or synthetic sweetener, such as any suitable caloric, low-caloric or non-caloric sweetener. The compound of Formula (I), or any one of Compounds 1-6, or combinations thereof may have an inherent sweet taste and, in some embodiments, it is present at or above its sweetness threshold, but is not the primary sweetener in the composition. Rather, the compound of Formula (I), or any one of Compounds 1-6, or combinations thereof serves to enhance the sweet taste of the sweetener. The compound of Formula (I), or any one of Compounds 1-6, or combinations thereof may be present at or below its sweetness threshold. In such cases, the compound serves only to enhance the sweet taste of the sweetener. A person of skill in the art will be able to select the concentration of the sweet taste modulator so that it may impart the perception of enhanced sweetness to a composition comprising a sweetener. For example, a skilled artisan may select a concentration for the sweet taste modulator so that it does not impart any perceptible sweetness to a composition that does not comprise a sweetener. Non-limiting examples of such sweeteners include caloric carbohydrate sweeteners, natural carbohydrate sweeteners, non-natural carbohydrate sweeteners, natural high-potency sweeteners, non-natural high-potency sweeteners, synthetic high potency sweeteners, synthetic carbohydrate sweeteners, and combinations thereof.
In some embodiments, the edible composition further comprises functional ingredients. The term “functional ingredient” refers to compound which provide a real or perceived heath benefit to the composition. Functional ingredients include, but are not limited to, saponins, antioxidants, dietary fiber sources, fatty acids, vitamins, glucosamine, minerals, preservatives, hydration agents, probiotics, prebiotics, weight management agents, osteoporosis management agents, phytoestrogens, long chain primary aliphatic saturated alcohols, phytosterols, and combinations thereof.
In some embodiments the edible compositions are beverages. In further embodiments, the beverage can also contain one or more functional ingredients, which provide a real or perceived heath benefit to the composition. Functional ingredients include, but are not limited to, saponins, antioxidants, dietary fiber sources, fatty acids, vitamins, glucosamine, minerals, preservatives, hydration agents, probiotics, prebiotics, weight management agents, osteoporosis management agents, phytoestrogens, long chain primary aliphatic saturated alcohols, phytosterols and combinations thereof.
In certain embodiments, the functional ingredient is at least one saponin. As used herein, the at least one saponin may comprise a single saponin or a plurality of saponins as a functional ingredient for the edible compositions (e.g., beverages) provided herein. Generally, according to particular embodiments of this invention, the at least one saponin is present in the edible composition (e.g., beverage) in a concentration sufficient to promote health and wellness.
Saponins are glycosidic natural plant products comprising an aglycone ring structure and one or more sugar moieties. The combination of the nonpolar aglycone and the water soluble sugar moiety gives saponins surfactant properties, which allow them to form a foam when shaken in an aqueous solution.
The saponins are grouped together based on several common properties. In particular, saponins are surfactants which display hemolytic activity and form complexes with cholesterol. Although saponins share these properties, they are structurally diverse. The types of aglycone ring structures forming the ring structure in saponins can vary greatly. Non-limiting examples of the types of aglycone ring structures in saponin for use in particular embodiments of the invention include steroids, triterpenoids, and steroidal alkaloids. Non-limiting examples of specific aglycone ring structures for use in particular embodiments of the invention include soyasapogenol A, soyasapogenol B and soyasopogenol E. The number and type of sugar moieties attached to the aglycone ring structure can also vary greatly. Non-limiting examples of sugar moieties for use in particular embodiments of the invention include glucose, galactose, glucuronic acid, xylose, rhamnose, and methylpentose moieties. Non-limiting examples of specific saponins for use in particular embodiments of the invention include group A acetyl saponin, group B acetyl saponin, and group E acetyl saponin.
Saponins can be found in a large variety of plants and plant products, and are especially prevalent in plant skins and barks where they form a waxy protective coating. Several common sources of saponins include soybeans, which have approximately 5% saponin content by dry weight, soapwort plants (Saponaria), the root of which was used historically as soap, as well as alfalfa, aloe, asparagus, grapes, chickpeas, yucca, and various other beans and weeds. Saponins may be obtained from these sources by using extraction techniques well known to those of ordinary skill in the art. A description of conventional extraction techniques can be found in U.S. Pat. Appl. No. 2005/0123662, the disclosure of which is expressly incorporated by reference.
In certain embodiments, the functional ingredient is at least one antioxidant. As used herein, the at least one antioxidant may comprise a single antioxidant or a plurality of antioxidants as a functional ingredient for the edible compositions (e.g., beverages) provided herein. Generally, according to particular embodiments of this invention, the at least one antioxidant is present in the edible composition (e.g., beverage) in a concentration sufficient to promote health and wellness.
As used herein “antioxidant” refers to any substance which inhibits, suppresses, or reduces oxidative damage to cells and biomolecules. Without being bound by theory, it is believed that antioxidants inhibit, suppress, or reduce oxidative damage to cells or biomolecules by stabilizing free radicals before they can cause harmful reactions.

In certain embodiments, the functional ingredient is at least one dietary fiber source. As used herein, the at least one dietary fiber source may comprise a single dietary fiber source or a plurality of dietary fiber sources as a functional ingredient for the edible compositions (e.g., beverages) provided herein. Generally, according to particular embodiments of this invention, the at least one dietary fiber source is present in the edible composition (e.g., beverage) in a concentration sufficient to promote health and wellness.
Numerous polymeric carbohydrates having significantly different structures in both composition and linkages fall within the definition of dietary fiber. Such compounds are well known to those skilled in the art, non-limiting examples of which include non-starch polysaccharides, lignin, cellulose, methylcellulose, the hemicelluloses, β-glucans, pectins, gums, mucilage, waxes, inulins, oligosaccharides, fructooligosaccharides, cyclodextrins, chitins, and combinations thereof.
Polysaccharides are complex carbohydrates composed of monosaccharides joined by glycosidic linkages. Non-starch polysaccharides are bonded with β-linkages, which humans are unable to digest due to a lack of an enzyme to break the β-linkages. Conversely, digestable starch polysaccharides generally comprise α(1-4) linkages.
Lignin is a large, highly branched and cross-linked polymer based on oxygenated phenylpropane units. Cellulose is a linear polymer of glucose molecules joined by a β(1-4) linkage, which mammalian amylases are unable to hydrolyze. Methylcellulose is a methyl esther of cellulose that is often used in foodstuffs as a thickener, and emulsifier. It is commercially available (e.g., Citrucel by GlaxoSmithKline, Celevac by Shire Pharmaceuticals). Hemicelluloses are highly branched polymers consisting mainly of glucurono- and 4-O-methylglucuroxylans. β-Glucans are mixed-linkage (1-3), (1-4) β-D-glucose polymers found primarily in cereals, such as oats and barley. Pectins, such as beta pectin, are a group of polysaccharides composed primarily of D-galacturonic acid, which is methoxylated to variable degrees.
Gums and mucilages represent a broad array of different branched structures. Guar gum, derived from the ground endosperm of the guar seed, is a galactomannan. Guar gum is commercially available (e.g., Benefiber by Novartis AG). Other gums, such as gum arabic and pectins, have still different structures. Still other gums include xanthan gum, gellan gum, tara gum, psylium seed husk gum, and locust been gum.
Waxes are esters of ethylene glycol and two fatty acids, generally occurring as a hydrophobic liquid that is insoluble in water.
Inulins comprise naturally occurring oligosaccharides belonging to a class of carbohydrates known as fructans. They generally are comprised of fructose units joined by β(2-1) glycosidic linkages with a terminal glucose unit. Oligosaccharides are saccharide polymers containing typically three to six component sugars. They are generally found either O- or N-linked to compatible amino acid side chains in proteins or to lipid molecules. Fructooligosaccharides are oligosaccharides consisting of short chains of fructose molecules.
Food sources of dietary fiber include, but are not limited to, grains, legumes, fruits, and vegetables. Grains providing dietary fiber include, but are not limited to, oats, rye, barley, wheat. Legumes providing fiber include, but are not limited to, peas and beans such as soybeans. Fruits and vegetables providing a source of fiber include, but are not limited to, apples, oranges, pears, bananas, berries, tomatoes, green beans, broccoli, cauliflower, carrots, potatoes, celery. Plant foods such as bran, nuts, and seeds (such as flax seeds) are also sources of dietary fiber. Parts of plants providing dietary fiber include, but are not limited to, the stems, roots, leaves, seeds, pulp, and skin.
Although dietary fiber generally is derived from plant sources, indigestible animal products such as chitins are also classified as dietary fiber. Chitin is a polysaccharide composed of units of acetylglucosamine joined by β(1-4) linkages, similar to the linkages of cellulose.
Sources of dietary fiber often are divided into categories of soluble and insoluble fiber based on their solubility in water. Both soluble and insoluble fibers are found in plant foods to varying degrees depending upon the characteristics of the plant. Although insoluble in water, insoluble fiber has passive hydrophilic properties that help increase bulk, soften stools, and shorten transit time of fecal solids through the intestinal tract.
Unlike insoluble fiber, soluble fiber readily dissolves in water. Soluble fiber undergoes active metabolic processing via fermentation in the colon, increasing the colonic microflora and thereby increasing the mass of fecal solids. Fermentation of fibers by colonic bacteria also yields end-products with significant health benefits. For example, fermentation of the food masses produces gases and short-chain fatty acids. Acids produced during fermentation include butyric, acetic, propionic, and valeric acids that have various beneficial properties such as stabilizing blood glucose levels by acting on pancreatic insulin release and providing liver control by glycogen breakdown. In addition, fiber fermentation may reduce atherosclerosis by lowering cholesterol synthesis by the liver and reducing blood levels of LDL and triglycerides. The acids produced during fermentation lower colonic pH, thereby protecting the colon lining from cancer polyp formation. The lower colonic pH also increases mineral absorption, improves the barrier properties of the colonic mucosal layer, and inhibits inflammatory and adhesion irritants. Fermentation of fibers also may benefit the immune system by stimulating production of T-helper cells, antibodies, leukocytes, splenocytes, cytokinins and lymphocytes.

In certain embodiments, the functional ingredient is chosen from at least one probiotic, prebiotic and combination thereof. As used herein, the at least one probiotic or prebiotic may be single probiotic or prebiotic or a plurality of probiotics or prebiotics as a functional ingredient for the edible compositions (e.g., beverages) provided herein. Generally, according to particular embodiments of this invention, the at least one probiotic, prebiotic or combination thereof is present in the edible composition (e.g., beverage) in a concentration sufficient to promote health and wellness.
Probiotics, in accordance with the teachings of this invention, comprise microorganisms that benefit health when consumed in an effective amount. Desirably, probiotics beneficially affect the human body's naturally-occurring gastrointestinal microflora and impart health benefits apart from nutrition. Probiotics may include, without limitation, bacteria, yeasts, and fungi.
According to particular embodiments, the probiotic is a beneficial microorganisms that beneficially affects the human body's naturally-occurring gastrointestinal microflora and imparts health benefits apart from nutrition. Examples of probiotics include, but are not limited to, bacteria of the genus Lactobacilli, Bifidobacteria, Streptococci, or combinations thereof, that confer beneficial effects to humans.
In particular embodiments of the invention, the at least one probiotic is chosen from the genus Lactobacilli. Lactobacilli (i.e., bacteria of the genus Lactobacillus, hereinafter “L.”) have been used for several hundred years as a food preservative and for promoting human health. Non-limiting examples of species of Lactobacilli found in the human intestinal tract include L. acidophilus, L. casei, L. fermentum, L. saliva roes, L. brevis, L. leichmannii, L. plantarum, L. cellobiosus, L. reuteri, L. rhamnosus, L. GG, L. bulgaricus, and L. thermophilus.
According to other particular embodiments of this invention, the probiotic is chosen from the genus Bifidobacteria. Bifidobacteria also are known to exert a beneficial influence on human health by producing short chain fatty acids (e.g., acetic, propionic, and butyric acids), lactic, and formic acids as a result of carbohydrate metabolism. Non-limiting species of Bifidobacteria found in the human gastrointestinal tract include B. angulatum, B. animalis, B. asteroides, B. bifidum, B. bourn, B. breve, B. catenulatum, B. choerinum, B. coryneforme, B. cuniculi, B. dentiurn, B. gallicum, B. gallinarum, B indicum, B. longum, B. magnum, B. merycicum, B. minimum, B. pseudocatenulatum, B. pseudolongum, B. psychraerophilum, B. pullorum, B. ruminantiurn, B. saeculare, B. scardovii, B. simiae, B. subtile, B. thermacidophilum, B. thermophilum, B. urinalis, and B. sp.
According to other particular embodiments of this invention, the probiotic is chosen from the genus Streptococcus. Streptococcus thermophilus is a gram-positive facultative anaerobe. It is classified as lactic acid bacteria, commonly found in milk and milk products, and is used in the production of yogurt. Other non-limiting probiotic species of this bacteria include Streptococcus salivarus and Streptococcus cremoris.
Probiotics that may be used in accordance with this invention are well-known to those of skill in the art. Non-limiting examples of foodstuffs comprising probiotics include yogurt, sauerkraut, kefir, kimchi, fermented vegetables, and other foodstuffs containing a microbial element that beneficially affects the host animal by improving the intestinal microbalance.
Prebiotics, in accordance with the teachings of this invention, are compositions that promote the growth of beneficial bacteria in the intestines. Prebiotic substances can be consumed by a relevant probiotic, or otherwise assist in keeping the relevant probiotic alive or stimulate its growth. When consumed in an effective amount, prebiotics also beneficially affect the human body's naturally-occurring gastrointestinal microflora and thereby impart health benefits apart from just nutrition. Prebiotic foods enter the colon and serve as substrate for the endogenous bacteria, thereby indirectly providing the host with energy, metabolic substrates, and essential micronutrients. The body's digestion and absorption of prebiotic foods is dependent upon bacterial metabolic activity, which salvages energy for the host from nutrients that escaped digestion and absorption in the small intestine.
Prebiotics, in accordance with the embodiments of this invention, include, without limitation, mucopolysaccharides, oligosaccharides, polysaccharides, amino acids, vitamins, nutrient precursors, proteins and combinations thereof.
According to a particular embodiment of this invention, the prebiotic is chosen from dietary fibers, including, without limitation, polysaccharides and oligosaccharides. These compounds have the ability to increase the number of probiotics, which leads to the benefits conferred by the probiotics. Non-limiting examples of oligosaccharides that are categorized as prebiotics in accordance with particular embodiments of this invention include fructooligosaccharides, inulins, isomalto-oligosaccharides, lactilol, lactosucrose, lactulose, pyrodextrins, soy oligosaccharides, transgalacto-oligosaccharides, and xylo-oligosaccharides.
According to other particular embodiments of the invention, the prebiotic is an amino acid. Although a number of known prebiotics break down to provide carbohydrates for probiotics, some probiotics also require amino acids for nourishment.
Prebiotics are found naturally in a variety of foods including, without limitation, bananas, berries, asparagus, garlic, wheat, oats, barley (and other whole grains), flaxseed, tomatoes, Jerusalem artichoke, onions and chicory, greens (e.g., dandelion greens, spinach, collard greens, chard, kale, mustard greens, turnip greens), and legumes (e.g., lentils, kidney beans, chickpeas, navy beans, white beans, black beans).
In certain embodiments, the functional ingredient is at least one weight management agent. As used herein, the at least one weight management agent may be single weight management agent or a plurality of weight management agents as a functional ingredient for the edible compositions (e.g., beverages) provided herein. Generally, according to particular embodiments of this invention, the at least one weight management agent is present in the edible composition (e.g., beverage) in a concentration sufficient to promote health and wellness.
As used herein, “a weight management agent” includes an appetite suppressant and/or a thermogenesis agent. As used herein, the phrases “appetite suppressant”, “appetite satiation compositions”, “satiety agents”, and “satiety ingredients” are synonymous. The phrase “appetite suppressant” describes macronutrients, herbal extracts, exogenous hormones, anorectics, anorexigenics, pharmaceutical drugs, and combinations thereof, that when delivered in an effective amount, suppress, inhibit, reduce, or otherwise curtail a person's appetite. The phrase “thermogenesis agent” describes macronutrients, herbal extracts, exogenous hormones, anorectics, anorexigenics, pharmaceutical drugs, and combinations thereof, that when delivered in an effective amount, activate or otherwise enhance a person's thermogenesis or metabolism.
Suitable weight management agents include macronutrient selected from the group consisting of proteins, carbohydrates, dietary fats, and combinations thereof. Consumption of proteins, carbohydrates, and dietary fats stimulates the release of peptides with appetite-suppressing effects. For example, consumption of proteins and dietary fats stimulates the release of the gut hormone cholecytokinin (CCK), while consumption of carbohydrates and dietary fats stimulates release of Glucagon-like peptide 1 (GLP-1).
Suitable macronutrient weight management agents also include carbohydrates. Carbohydrates generally comprise sugars, starches, cellulose and gums that the body converts into glucose for energy. Carbohydrates often are classified into two categories, digestible carbohydrates (e.g., monosaccharides, disaccharides, and starch) and non-digestible carbohydrates (e.g., dietary fiber). Studies have shown that non-digestible carbohydrates and complex polymeric carbohydrates having reduced absorption and digestibility in the small intestine stimulate physiologic responses that inhibit food intake. Accordingly, the carbohydrates embodied herein desirably comprise non-digestible carbohydrates or carbohydrates with reduced digestibility. Non-limiting examples of such carbohydrates include polydextrose; inulin; monosaccharide-derived polyols such as erythritol, mannitol, xylitol, and sorbitol; disaccharide-derived alcohols such as isomalt, lactitol, and maltitol; and hydrogenated starch hydrolysates. Carbohydrates are described in more detail herein below.
In another particular embodiment weight management agent is a dietary fat. Dietary fats are lipids comprising combinations of saturated and unsaturated fatty acids. Polyunsaturated fatty acids have been shown to have a greater satiating power than mono-unsaturated fatty acids. Accordingly, the dietary fats embodied herein desirably comprise poly-unsaturated fatty acids, non-limiting examples of which include triacylglycerols.

In certain embodiments, the functional ingredient is at least one long chain primary aliphatic saturated alcohol. As used herein, the at least one long chain primary aliphatic saturated alcohol may be single long chain primary aliphatic saturated alcohol or a plurality of long chain primary aliphatic saturated alcohols as a functional ingredient for the edible compositions (e.g., beverages) provided herein. Generally, according to particular embodiments of this invention, the at least one long chain primary aliphatic saturated alcohol is present in the edible composition (e.g., beverage) in a concentration sufficient to promote health and wellness.
Long-chain primary aliphatic saturated alcohols are a diverse group of organic compounds. The term alcohol refers to the fact these compounds feature a hydroxyl group (—OH) bound to a carbon atom. The term primary refers to the fact that in these compounds the carbon atom which is bound to the hydroxyl group is bound to only one other carbon atom. The term saturated refers to the fact that these compounds feature no carbon to carbon pi bonds. The term aliphatic refers to the fact that the carbon atoms in these compounds are joined together in straight or branched chains rather than in rings. The term long-chain refers to the fact that the number of carbon atoms in these compounds is at least 8 carbons).
Non-limiting examples of particular long-chain primary aliphatic saturated alcohols for use in particular embodiments of the invention include the 8 carbon atom 1-octanol, the 9 carbon 1-nonanol, the 10 carbon atom 1-decanol, the 12 carbon atom 1-dodecanol, the 14 carbon atom 1-tetradecanol, the 16 carbon atom 1-hexadecanol, the 18 carbon atom 1-octadecanol, the 20 carbon atom 1-eicosanol, the 22 carbon 1-docosanol, the 24 carbon 1-tetracosanol, the 26 carbon 1-hexacosanol, the 27 carbon 1-heptacosanol, the 28 carbon 1-octanosol, the 29 carbon 1-nonacosanol, the 30 carbon 1-triacontanol, the 32 carbon 1-dotriacontanol, and the 34 carbon 1-tetracontanol.
In a particularly desirable embodiment of the invention, the long-chain primary aliphatic saturated alcohols are policosanol. Policosanol is the term for a mixture of long-chain primary aliphatic saturated alcohols composed primarily of 28 carbon 1-octanosol and 30 carbon 1-triacontanol, as well as other alcohols in lower concentrations such as 22 carbon 1-docosanol, 24 carbon 1-tetracosanol, 26 carbon 1-hexacosanol, 27 carbon 1-heptacosanol, 29 carbon 1-nonacosanol, 32 carbon 1-dotriacontanol, and 34 carbon 1-tetracontanol.
Long-chain primary aliphatic saturated alcohols are derived from natural fats and oils. They may be obtained from these sources by using extraction techniques well known to those of ordinary skill in the art. Policosanols can be isolated from a variety of plants and materials including sugar cane (Saccharum officinarium), yams (e.g. Dioscorea opposite), bran from rice (e.g. Oryza sativa), and beeswax. Policosanols may be obtained from these sources by using extraction techniques well known to those of ordinary skill in the art. A description of such extraction techniques can be found in U.S. Pat. Appl. No. 2005/0220868, the disclosure of which is expressly incorporated by reference.
In certain embodiments, the functional ingredient is at least one phytosterol, phytostanol or combination thereof. Generally, according to particular embodiments of this invention, the at least one phytosterol, phytostanol or combination thereof is present in the edible composition (e.g., beverage) in a concentration sufficient to promote health and wellness.
As used herein, the phrases “stanol”, “plant stanol” and “phytostanol” are synonymous.
Plant sterols and stanols are present naturally in small quantities in many fruits, vegetables, nuts, seeds, cereals, legumes, vegetable oils, bark of the trees and other plant sources. Although people normally consume plant sterols and stanols every day, the amounts consumed are insufficient to have significant cholesterol-lowering effects or other health benefits. Accordingly, it would be desirable to supplement food and beverages with plant sterols and stanols.
Sterols are a subgroup of steroids with a hydroxyl group at C-3. Generally, phytosterols have a double bond within the steroid nucleus, like cholesterol; however, phytosterols also may comprise a substituted sidechain (R) at C-24, such as an ethyl or methyl group, or an additional double bond. The structures of phytosterols are well known to those of skill in the art.
At least 44 naturally-occurring phytosterols have been discovered, and generally are derived from plants, such as corn, soy, wheat, and wood oils; however, they also may be produced synthetically to form compositions identical to those in nature or having properties similar to those of naturally-occurring phytosterols. According to particular embodiments of this invention, non-limiting examples of phytosterols well known to those or ordinary skill in the art include 4-desmethylsterols (e.g., β-sitosterol, campesterol, stigmasterol, brassicasterol, 22-dehydrobrassicasterol, and Δ5-avenasterol), 4-monomethyl sterols, and 4,4-dimethyl sterols (triterpene alcohols) (e.g., cycloartenol, 24-methylenecycloartanol, and cyclobranol).
As used herein, the phrases “stanol”, “plant stanol” and “phytostanol” are synonymous. Phytostanols are saturated sterol alcohols present in only trace amounts in nature and also may be synthetically produced, such as by hydrogenation of phytosterols. According to particular embodiments of this invention, non-limiting examples of phytostanols include β-sitostanol, campestanol, cycloartanol, and saturated forms of other triterpene alcohols.
Both phytosterols and phytostanols, as used herein, include the various isomers such as the α and β isomers (e.g., α-sitosterol and β-sitostanol, which comprise one of the most effective phytosterols and phytostanols, respectively, for lowering serum cholesterol in mammals).
The phytosterols and phytostanols of the present invention also may be in their ester form. Suitable methods for deriving the esters of phytosterols and phytostanols are well known to those of ordinary skill in the art, and are disclosed in U.S. Pat. Nos. 6,589,588, 6,635,774, 6,800,317, and U.S. Patent Publication Number 2003/0045473, the disclosures of which are incorporated herein by reference in their entirety. Non-limiting examples of suitable phytosterol and phytostanol esters include sitosterol acetate, sitosterol oleate, stigmasterol oleate, and their corresponding phytostanol esters. The phytosterols and phytostanols of the present invention also may include their derivatives.
Generally, the amount of functional ingredient in the edible composition (e.g., beverage) varies widely depending on the particular edible composition (e.g., beverage) and the desired functional ingredient. Those of ordinary skill in the art will readily ascertain the appropriate amount of functional ingredient for each beverage.
In some embodiments, the edible composition further comprises a solubilizing agent, as discussed herein. Compounds—such as sweet taste modulators—have a particular solubility in aqueous solutions. As would be evident to one of skill in the art, the solubility of a compound depends on a number of factors including, but not limited to, the chemical structure of the compound, the solvent, the pH of the solvent, etc. Solubilizing agents may be used to increase the amount of a compound, such as a sweet taste modulator, that may be dissolved in a particular amount of solvent. In some embodiments, a compound according to Formula (I) or Compounds 1-6, as defined herein, is solubilized by converting the compound into one or more crystalline forms, amorphous forms, one or more alcohol solvate forms, one or more hydrate forms, or mixtures thereof.
In some embodiments, the edible composition further comprises a surfactant to increase or decrease the effectiveness of the compounds of the present invention as sweet taste modulators. Suitable surfactants include, but are not limited to, non-ionic surfactants (e.g., mono and diglycerides, fatty acid esters, sorbitan esters, propylene glycol esters, and lactylate esters) anionic surfactants (e.g., sulfosuccinates and lecithin) and cationic surfactants (e.g., quaternary ammonium salts).
The rate of release of the sweet taste modulator of the present invention may be regulated. The release rate of the sweet taste modulator of the present invention can be altered by, for example, varying its solubility in water. Rapid release can be achieved by encapsulating the sweet taste modulator of the present invention with a material with high water solubility. Delayed release of the sweet taste modulator of the present invention can be achieved by encapsulating the sweet taste modulator of the present invention with a material with low water solubility. The sweet taste modulator of the present invention can be co-encapsulated with carbohydrates or masking tastants such as sweeteners. The rate of release of the sweet taste modulator of the present invention can also be regulated by the degree of encapsulation. In some embodiments, the sweet taste modulator of the present invention is fully encapsulated. In other embodiments, the compounds of the present invention are partially encapsulated. In some embodiments, the rate of release may be regulated so as to release with the sweet taste modulator. In some embodiments, the rate of release may be regulated in a manner that is dependent on the structure of the sweetener and sweet taste modulator.
The edible compositions of this invention are prepared according to techniques well-known in the art. In general, an edible composition of the invention is prepared by mixing a component or ingredient of the edible composition, such as a sweetener, with a sweet taste modulating compound of the invention. Alternatively, a sweet taste modulating compound of the invention can be added directly to the edible composition comprising a sweetener. In some embodiments, a sweetener is added simultaneously or sequentially with a sweet taste modulating compound of the invention. If sequentially, the sweetener may be added before or after the sweet taste modulating compound of the invention. In some embodiments, the edible composition is a food product. In some embodiments, the edible composition is a pharmaceutical composition. In some embodiments, the edible composition is a consumer product. In some embodiments, the edible composition is in the form of, for example, a gum, lozenge, sauce, condiment, meat matrix, meat slurry, paste, suspension, spread, coating, a liquid, a gel, an emulsion, granules, or seasoning.
The amount of both a sweet taste modulating compound of the present invention and a sweetener used in an edible composition depends upon a variety of factors, including the purpose of the composition and the desired or acceptable perception of sweetness. The amount may depend on the nature of the edible composition, the particular compound added, the sweetener, other compounds present in the composition, the method of preparation (including amount of heat used), and the pH of the edible composition. Those of skill in the art will know how to determine the amounts needed to produce the desired taste(s).

These amounts are not meant to be limiting, and increments between the recited percentages are specifically envisioned as part of the invention.
In some embodiments, the method of enhancing the sweet taste attributed to a sweetener in an edible composition further comprises adding at least one additional additive, such as a sweet taste improving composition, and/or a sweet taste improving additive.
Another aspect of the invention provides a method of enhancing or potentiating activation and/or signaling of a sweet taste receptor. In some embodiments, the method comprises contacting a sweet taste receptor with a compound according to Formula (I), or any one of Compounds 1-6, as described herein, or combinations thereof, in the presence of a sweetener.
In some embodiments, the method comprises contacting a sweet taste receptor with an edible composition comprising a compound according to Formula (I), or any one of Compounds 1-6, as described herein, or combinations thereof, in the presence of a sweetener. The edible composition may be a food product, a pharmaceutical composition, or a consumer product. In such methods, an amount of solubilizing agent may also be present in the edible composition, as described herein.
In various embodiments, the sweet taste receptor is an ex vivo or in vivo receptor present in, for example, an assay. The sweet taste receptor also may be an in vivo receptor present in a subject. In such embodiments, the sweet taste receptor is typically present in the oral cavity or gastrointestinal tract of the subject. In some embodiments, the sweet receptor is in the oral cavity of a human. Alternatively, the sweet receptor is in the oral cavity of a non-human animal, such as an animal model.
An in vivo sweet responsive assay means an assay where an assessment of increased perception of sweetness can be ascribed. Such an assay may be, for example, but not limited to, a human sensory descriptive analysis panel, a human sensory discriminative panel, and/or an expert flavorist assessment. Non-human assessments of sweet response include, but not limited to, operant conditioned animal studies of sweetness taste perception and/or lick rate/amount bottle preference tests
An in vitro sweet responsive assay refers to an assay where an assessment of increased sweet response or interaction can be ascribed. An example of such an assay may be, but is not limited to, in vitro receptor binding assays, in vitro receptor cell-based assays, and/or electronic tongue taste analysis.
In some embodiments, enhancement of a sweet taste receptor activation will affect a physiological process or condition. Non-limiting examples of physiological processes and conditions affected by the enhancement of sweet taste receptor activation include sweet taste, effects on the gastrointestinal tract, appetite, nutrition, nutrient absorption, satiety, hunger, diabetes, obesity, blood glucose levels, blood glucose regulation, metabolism, diet, and eating disorders.
In addition to sweetness modulation, compounds of Formula I, compounds 1-6 or combinations thereof, can be suitable for masking or reducing an unpleasant taste sensation, in particular a bitter taste sensation of a bitter-tasting substance. Compounds of Formula I, compounds 1-6 or combinations thereof, can both synergistically enhance the sweet taste sensation of sweeteners like steviol glycosides (for example occurring naturally in Stevia ssp.) and mask or reduce the bitter taste sensation of such steviol glycosides or other bitter tasting sweeteners such as acesulfame-K, saccharin, steviosides, or rebaudiosides. Preparations comprising the bitter blocking compounds of the invention can be made in the same or similar manner and concentration as the preparations comprising the sweet taste enhancing preparations of the invention.
In one embodiment, Compound 1 and Compound 4 are prepared by the multi-step sequences described below. One of skill in the art would be able to readily adapt the described conditions for the synthesis of any of the compounds of Formula (I).

Extraction from these natural sources may be done using mixtures of aqueous alcohol with the alcohol content ranging from about 10% to about 99%, or more usually, from about 50 to about 95%. In some embodiments, extraction from these natural sources may be done using mixtures of aqueous alcohol with the alcohol content ranging from 10% to 99%, or more usually, from 50 to 95%. Examples of alcohols suitable for use include but are not limited to methanol, ethanol, propanol, isopropanol, n-butyl alcohol or mixtures thereof. Examples of alcohol compositions for use in extractions may be 80:20 or 60:40 (volume/volume) methanol:water or ethanol:water. An example of purification involves partitioning the crude material between an aqueous alcohol and an organic solvent. The residue obtained by evaporation of the solvent into which the compound of interest is partitioned into is further purified by high performance liquid chromatography (HPLC), typically using reversed-phase support materials such as C-18 Hypersil. Gradients for use in HPLC are known, with an example of a typical gradient being 20% methanol in water, increasing to about 80-85% methanol in water over twenty minutes or 80-85% methanol in water over twenty minutes. Further examples of extraction, isolation and purification of compounds from naturally-occurring sources may be carried out using conventional techniques and procedures known in the art, such as “Natural Products Isolation”, in “Methods in Biotechnology”, Second Edition, Satyajit D. Sarker, Zahid Latif, Alexander I Gray (editors), Humana Press, 2006, Totowa, New Jersey. This reference is incorporated herein in its entirety.

In order that this invention be more fully understood, the following examples are set forth. These examples are for the purpose of illustration only and are not to be construed as limiting the scope of the invention in any way.
The test compounds used in the following examples may be obtained from the synthetic methods disclosed above.
The taste test panelists used in the Example 1 were selected using a sensory acuity screening program. Candidate taste panelists were recruited, with prescreening and personal interviews, and were assessed and for their ability to detect, recognize and differentiate basic taste attributes or mixtures thereof as part of a standardized acuity test. This included basic tastes of sweet, sour, salty, bitter and umami, as well as having the capacity to focus on specific aspects of sensory character such as ranking the various tastes perceived and identifying the basic tastes presented at threshold levels.
Due to the complex nature of taste perception in subjects and the inherently subjective nature of the following experiments, individual taste test trials may yield different results for a given compound. The data presented in the following Examples is illustrative of the taste testing results observed.
The taste testing experiments below were conducted with panels of varying size (i.e., panels comprising varying numbers of panelists).
Effect of test compounds on the perception of sweet taste of high fructose cornsyrup (HFCS) two-alternative forced choice method (2AFC).
The effect of the test compounds on the perception of the sweet taste of an aqueous solution of sweetener in humans was evaluated using a two-alternative forced choice “sip and spit” method (2AFC).
The aqueous sweetener solutions were prepared by adding sucrose equivalent (SE) quantities of high fructose corn syrup (HFCS) (by weight), to water to achieve the desired concentration. The aqueous solutions ranged in pH from pH 2.5-pH 7. Compounds of the invention were first prepared as a 500-fold concentrated stock solution in 100% ethanol. These concentrated stocks were then added to the aqueous sweetener solutions to result in a final ethanol concentration of 0.2%. The control (positive and negative) samples were also normalized to 0.2% ethanol. This level of ethanol was not seen to contribute any perceived sweetness.
The 2AFC test used for compound evaluation was a double blinded and randomized test where taste panelists (n≧15) evaluate a pair of sweetener solutions at a time—one sample contains aqueous sweetener solution plus compound (i.e. test) while the other contains aqueous sweetener solution at higher concentration without compound (i.e. positive control). Each test sample was compared against a positive control. For example, if the test sample contained 1× sweetener concentration with compound (e.g. 5brix HFCS with compound), the positive control sample contained a 1.1× sweetener concentration (e.g. 5.5brix HFCS without compound). In this manner, compounds were not assessed simply for an increase in perceived sweetness, but a significant increase in perceived sweetness above the positive control.
Panelists were instructed not to eat or drink (except water) for at least 1 hour before the test. During the test, panelists were instructed to sip each sample, swirl it around their mouth and then expectorate. After tasting each sample in the pair, panelists were instructed to record the sample that is “sweeter” in taste. Panelists cleansed their palates by rinsing with water, eating a cracker and waiting for an interval of about 5 minutes. All samples were tasted at ambient temperatures. Data were analyzed using binomial probabilities. The results of the 2AFC analysis are presented in Table 1, below.
Approximate levels of sweetness enhancement in column 5 of Table 2 were calculated as follows:
Approximate levels of sweetness enhancement=Sweetener concentration of positive control surpassed by the test sample, divided by sweetener concentration for compound-containing sample (e.g.1.3×=6.5brix HFCS/5brix HFCS). This only indicates that the perceived increase is greater than the positive control, but does not indicate the degree with which the positive control concentration was surpassed.
The aqueous sweetener solutions were prepared by adding sucrose equivalent quantities of HFCS (by weight), to water to achieve the desired concentration. The aqueous solutions ranged in pH from 2.5-pH 7.
Compounds were first prepared as a 500-fold concentrated stock solution in 100% ethanol. These concentrated stocks were then added to the aqueous sweetener solutions to result in a final ethanol concentration of 0.2%. The control (positive and negative) samples were also normalized to 0.2% ethanol. This level of ethanol was not seen to contribute any perceived sweetness
The intrinsic effect of test compounds on the perception of sweet taste, in an aqueous solution, in humans was evaluated using 2AFC methodology. This test was a double-blinded, randomized study where taste panelists (n≧20) evaluate a pair of sweetener solutions at a time—one sample contains aqueous solutions, without sweetener, plus compound (i.e. test) while the other contains aqueous solution containing 1.5% sucrose equivalent (SE), HFCS (i.e. control). Each test sample is compared against the sweetener control to observe if the test is significantly less sweet than the control sample.
Panelists were instructed not to eat or drink (except water) for at least 1 hour before the test. During the test, panelists were instructed to sip each sample, swirl it around their mouth and then expectorate. After tasting each sample in the pair, panelists were instructed to record the sample that is “sweeter” in taste. Panelists cleansed their palates by rinsing with water, eating a cracker and waiting for an interval of about 5 minutes. Each pair was tasted twice. All samples were tasted at ambient temperatures. Data were analyzed using binomial probabilities
The results of the inherent sweetness analysis are presented in Table 3, below.
For each compound listed in Table 3: The control sample of 1.5% SE HFCS is significantly sweeter than each of the test samples.
The effect of the test compound on the perception of the sweet taste in a flavored aqueous environment, in the presence of carbohydrate sweeteners, was evaluated using a descriptive analysis methodology with a group of trained panelists, as follows.
Candidate panelists were recruited, with prescreening and personal interviews, and were assessed for their ability to detect, recognize and differentiate basic taste attributes or mixtures thereof as part of a standardized acuity test. These candidate panelists were also assessed for their innate ability to identify flavors, and to rank on intensity scales. Other senses such as smell and vision were also included as part of the assessment. Candidates also were screened for their ability to use the language to describe and articulate ideas.
Selected candidates proceeded to training as a group in three phases: (1) Lexicon development, (2) Concept alignment, and (3) Scaling descriptors. During lexicon development, panelists evaluated products appropriate for use in the study to generate and align on terms describing the flavor, taste, aromatic, trigeminal, and temporal attributes. During concept alignment, the panel evaluated the products mentioned above to clarify and confirm the attributes that were generated during lexicon development using reference standards that appropriately define each attribute; these are either physical references (e.g. sucrose solutions) or verbal descriptions (e.g. overall flavor). Product terms and concepts were validated during this portion of the study.
In the last phase, scaling descriptors, the panel participated in a series of exercises focused on ordering and ranking samples according to relative attribute intensity, measuring attribute intensity using a defined length of line scale. Whenever possible, different levels or concentration of references were used as anchors to facilitate use of the scale. Panelists were provided with blinded references at this stage to evaluate their understanding and perception of the scale.
The panel used in this example was trained to reference sweet attributes in an absolute manner, such that a particular concentration of sweetener is always measured by the panelists at the same point using a 15 cm line scale where each cm represents a 1% increase in sucrose to cover the range of 0% to 15% sucrose. For the rest of the attributes, the panel was trained using a hybrid approach between descriptive analysis methods well-known to those skilled in the art. Panel performance was measured at regular intervals, and for data presented, the cohort of 12 panelists demonstrated good performance for reproducibility measured as a panel average of 81%, and defined as the number of attributes with reproducibility comparable to group performance (p<0.05), discrimination measured as a panel average of 93%, and defined as the number of attributes significantly different at a 90% confidence level individually (p<0.1), and agreement measured with a cohort average of 72% and defined as the number of attributes that correlate well to the panel consensus (R>0.7).
The trained panel was then used for a descriptive analysis assessment for Compound 2 and Compound 5 in flavored lemon lime matrix. Compound 2 was assessed at a dose of 50 ppm and Compound 5 was assessed at a dose of 20 ppm for sweetness enhancement in high fructose corn syrup (HFCS) sweetened lemon lime matrix.
The flavored sweetener solutions were prepared by adding sucrose equivalent quantities of HFCS (by weight), to lemon lime matrix to achieve the desired concentration. Compound was first prepared as a 500-fold concentrated stock solution in 100% ethanol. The concentrated stocks were then added to the flavored sweetener solutions to result in a final ethanol concentration of 0.2%. The control (positive and negative) samples were also normalized to 0.2% ethanol. This level of ethanol was not seen to contribute any perceived sweetness
Both control (flavored sweetener solutions without compound) and variant (flavored sweetener solutions with compound) samples were blinded and randomized. Samples were presented in monadic order and panelists were instructed to sip the sample, swirl it in their mouths and expectorate. A total of 7 attributes including sweet, bitter, sour, licorice and thickness were assessed for each sample. For the sweet attribute, panelists made an absolute scoring on a 15 cm line scale where each cm represents a 1% increase in sucrose to cover the range of 0% to 15% sucrose. After each sample assessment, panelists performed a standard palate cleansing protocol, and observed an inter-sample interval time (ISI). All samples were evaluated at ambient temperatures.
Data was collected and exported electronically utilizing FIZZ sensory software. Data analysis was conducted using SENPAQ version 5.0 software that uses tools such as ANOVA, Fisher's LSD, correlation to determine panel performance as well as significant differences between samples and attributes.
Illustrative results of this DA assessment are presented in Tables 4 and 5.
Sweetness intensities observed for compound-containing solution (i.e. variant) was significantly different from negative control solutions, as determined by ANOVA. The letter “a” indicates significant differences among the samples at 95% confidence level. Fold enhancement (increase in perceived sweetness) was calculated by dividing the DA panel average intensity score observed for a variant sample by that observed for the negative control sample.
The effect of the test compound on the perception of non-sweet taste attributes (such as bitterness) in a flavored aqueous environment, in the presence of carbohydrate sweeteners, was evaluated using a descriptive analysis methodology with a group of trained panelists, as follows. This occurred as part of DA assessment described previously in Example 3.
Candidate panelists were recruited, and trained as described previously, in Example 3, above.
The trained panel was then used for a descriptive analysis assessment for Compound 2 and Compound 5 in lemon lime flavored matrix, sweetened with high fructose corn syrup (HFCS), at a test dose of 50 ppm and 20 ppm, respectively.
All control and variant samples were prepared as described in Example 3. Both control (flavored sweetener solutions without compound) and variant (flavored sweetener solutions with compound) samples were blinded and randomized. Samples were presented in monadic order and panelists were instructed to sip the sample, swirl it in their mouths and expectorate. A total of 7 attributes including sweet, bitter, sour, licorice and thickness were assessed for each sample. After each sample assessment, panelists performed a standard palate cleansing protocol, and observed an inter-sample interval time (ISI). All samples were evaluated at ambient temperatures.
Data was collected and exported electronically utilizing FIZZ sensory software. Data analysis was conducted using SENPAQ version 5.0 software that uses tools such as ANOVA, Fisher's LSD, correlation to determine panel performance as well as significant differences between samples and attributes.
