20140193561
The present invention relates to an additive for carbonated beverages that comprises as the active ingredient spilanthol or a spilanthol-containing plant extract or plant essential oil, to carbonated beverages and flavorings for carbonated beverages that contain the aforementioned additive, and to a method of enhancing or maintaining the carbonated feel of carbonated beverages by addition of the additive.
Carbonated beverages such as soda pops and colas add pleasure to daily life and have long been popular types of soft drinks among children and adults. They are particularly enjoyed as thirst quenching beverages in hot summer periods or when perspiring after exercise. Carbonated beverages have a characteristic “carbonated feel” (an intense, refreshing stimulation on the throat produced by carbon dioxide gas, or a cool (refreshing) feel created by the combination of carbon dioxide gas and flavor) not shared by other types of soft drinks, which contributes to its effect of quenching thirst. However, carbonated beverages may not exhibit a satisfactory carbonated feel when prepared in combination with added substances such as juices, sweeteners, color additives, flavorings and the like. Furthermore, when rapid escape of carbon dioxide gas occurs after cap opening, resulting in “flatness”, the carbonated beverage loses the essential intense, refreshing stimulation of the carbon dioxide gas, thereby reducing the carbonated feel and quickly lowering the palatability after the cap has been opened.
Carbonated beverages hitherto proposed include carbonated beverages containing specific proportions of high-sweetness sweeteners in formulations containing relatively large amounts of carbon dioxide gas and plant components such as fruit juices, to provide a soothing, refreshing feel along with both the rich taste of the plant components and the stimulation of carbon dioxide gas (Patent document 1), and carbonated beverages with enhanced quality of taste including stimulation, creamy texture and rich taste, produced with addition of DE9-20 amylolysis product to the carbonated beverages (Patent document 2). However, no methods are yet known for enhancing the carbonated feel, including the stimulating and refreshing feel of carbon dioxide gas, which is reduced due to the effects of other materials in the beverage and escape of gas after cap opening.
It is an object of the present invention to solve the problems of reduced carbonated feel resulting from combination with added materials such as fruit juices, sweeteners, color additives and flavorings, of reduced carbonated feel caused by rapid escape of carbon dioxide gas after cap opening, and of accelerated loss of function or palatability as a thirst-quenching beverage after opening of the cap.
As a result of research on materials that enhance the carbonated feel of carbonated beverages with the aim of solving the problems described above, the present inventors have completed this invention upon discovering that addition of a small amount of spilanthol enhances the desirable stimulation of carbonation produced by carbon dioxide gas, thereby enhancing and maintaining the carbonated feel of beverages.
Specifically, the present invention provides an additive for carbonated beverages that comprises as the active ingredient spilanthol or a spilanthol-containing plant extract or plant essential oil, as well as an additive for carbonated beverages wherein the spilanthol-containing plant is Spilanthes acmella or Spilanthes acmella var. oleracea.
The invention further provides a flavoring composition for carbonated beverages characterized by containing the aforementioned additive for carbonated beverages. The invention still further provides carbonated beverages characterized by containing the aforementioned additive for carbonated beverages or flavoring composition for carbonated beverages, wherein the carbonated beverages contain spilanthol at 1-300 ppb. The carbonated beverages are also characterized by having citrus-based flavors.
The invention still further provides a method for enhancing or maintaining the carbonated feel of a carbonated beverage, by addition of the aforementioned additive for carbonated beverages or flavoring composition for carbonated beverages to a spilanthol content of 1-300 ppb in the carbonated beverage.
Addition of the additive for carbonated beverages of the invention to a carbonated beverage prevents loss of the carbonated feel that occurs by combination with materials such as fruit juices, sweeteners and the like. Moreover, loss of the carbonated feel due to escape of carbon dioxide gas after cap opening is minimized, and the intended function and palatability as a thirst-quenching beverage is maintained even after opening of the cap.
The spilanthol used for the invention is N-isobutyl-2,6,8-decatrieneamide, represented by the chemical formula shown below, which is a pungent component found in Spilanthes acmella, Spilanthes acmella var. oleracea, and other varieties.
CH3CH═CH—CH═CH(CH2)2CH═CHCONHCH2CH(CH3)2
Spilanthol can be obtained by extraction and purification from these plants, or it may be chemically synthesized. Spilanthol obtained by any such methods may be used for the invention, and it does not need to be a highly purified form. Spilanthol-containing plant extracts or essential oils may be used without purification so long as their tastes and odors do not adversely affect the flavor of the carbonated beverage. From the viewpoint of safety it is preferred to use extracts or essential oils obtained from proven edible plants, while from the viewpoint of supply, cost and other practical factors, it is particularly preferred to use extracts or essential oils of Spilanthes acmella or Spilanthes acmella var. oleracea, which have high spilanthol contents.
The spilanthol may be obtained by extraction or distillation from the total herb or flower head of Spilanthes acmella or Spilanthes acmella var. oleracea, which have high spilanthol contents. Using extraction for the sake of illustration, flower heads of Spilanthes acmella or Spilanthes acmella var. oleracea are dried and crushed and then subjected to extraction with an organic solvent to obtain a spilanthol-containing extract. The organic solvent used for extraction is not particularly restricted, and may be an alcohol such as methanol, ethanol, propanol or propylene glycol, a ketone such as acetone, an ester such as ethyl acetate, an ether such as diethyl ether or a hydrocarbon such as hexane or heptane, either alone or in admixture as appropriate. A polar organic solvent such as an alcohol is preferred, with ethanol being particularly preferred from the standpoint of safety. The solvent is distilled off from the obtained extract solution to obtain the spilanthol-containing extract.
The spilanthol-containing extract may be used directly as an additive for carbonated beverages according to the invention, but in cases where components other than the spilanthol in the extract may adversely affect the taste of the carbonated beverage, it is preferred to increase the spilanthol content by a purification method such as distillation.
The purification method may be molecular distillation, thin-film distillation or a chromatography method, and such purification methods may be used alone or in appropriate combinations to obtain an additive for carbonated beverages with a higher spilanthol content.
The additive for carbonated beverages of the invention may be added alone to a carbonated beverage, but it may also be combined with any other desired flavoring components for use in a flavoring composition for carbonated beverages. Flavoring components to be used in combination therewith are not particularly restricted, and as suitable examples there may be mentioned synthetic and natural-derived flavorings such as ethyl

When an additive for carbonated beverages or a flavoring composition containing an additive for carbonated beverages according to the invention is added to a carbonated beverage, it prevents loss of the carbonated feel that occurs by mixture with materials such as fruit juices, sweeteners and the like, while also preventing a reduced carbonated feel due to escape of carbon dioxide gas after opening of the cap.
There are no particular restrictions on the amount added to a carbonated beverage, but generally the spilanthol content in the final carbonated beverage product is preferred to be 1-300 ppb, more preferably 5-150 ppb and even more preferably 15-100 ppb. A spilanthol content of less than 1 ppb may not produce a sufficient effect, while a spilanthol content of greater than 300 ppb will tend to bring out the pungency of the spilanthol. Spilanthol is used in oral compositions such as dental pastes to enhance the refreshing feel of menthol and the like (JP S48-43870 B), but the amount of spilanthol added is 1 ppm or greater in such oral compositions; in contrast, the additive for carbonated beverages of the invention provides a maintaining and enhancing effect on the carbonated feel even with an addition amount of below 1 ppm.
The term “carbonated beverage” generally refers to beverages having carbon dioxide gas injected into water and beverages further containing sweeteners, acidulants, flavorings and the like, but according to the invention the term “carbonated beverage” also includes carbon dioxide-containing alcohol beverages.
As examples there may be mentioned carbonated water, carbonated beverages (soda pop, lemonade, etc.) with added flavors such as lemon, lemon-lime, lime, orange, grapefruit, grape, apple and the like, ginger ale, cola carbonated beverages, fruit juice-containing carbonated beverages, dairy product-containing carbonated beverages, carbon dioxide-containing liquors such as canned chu-hi, sparkling wine, beer, low-malt beer (Happoshu) and the like, although there is no limitation to these.
Also, as mentioned above, the term “carbonated feel” used for the purpose of the invention refers to an intense, refreshing stimulation on the throat produced by carbon dioxide gas, or a cool (refreshing) feel created by the combination of carbon dioxide gas and flavor, and the additive for carbonated beverages of the invention exhibits a particularly notable effect for soda pop beverages with citrus-based flavors, or cola carbonated beverages. Because the effect is particularly notable for enhancing citrus-based flavors, the additive is preferably used for carbonated beverages with citrus-based flavors.
The present invention will now be explained in greater detail through examples.
To 10 kg of dried flower heads of Spilanthes acmella (crushed to about 5 mm) there was added 100 kg of 99 volt ethanol, and extraction was carried out at 75° C. reflux temperature for 5 hours. After cooling the extract solution to 40° C., the solid and liquid portions were separated with a centrifugal separator and the extract was concentrated to 20 kg under reduced pressure. After adding 0.2 kg of active carbon to the concentrate and stirring for 1 hour, diatomaceous earth was added, pressure filtration was performed to remove the active carbon, and the extract was further concentrated under reduced pressure to obtain 0.43 kg of a Spilanthes acmella concentrate. Next, 2 kg of distilled water was added to the concentrate and extraction was performed three times with 2 kg of ethyl acetate.
The extracted ethyl acetate layers were pooled, diatomaceous earth was added, pressure filtration was performed, and the mixture was concentrated under reduced pressure to obtain 0.31 kg of a Spilanthes acmella crude extract. Yield: 3.1%. Spilanthol content: 12.4%.
After combining 100 g of the Spilanthes acmella crude extract to 100 g of fatty acid triglycerides, a reduced pressure thin-film distillation apparatus was used for distillation at a degree of vacuum of 3-5 Pa and a vaporization surface temperature of 110-150° C., to obtain 33.3 g of distillate. Yield: 33%. Spilanthol content: 38.0 wt %.
A 0.1 g portion of the distillate was diluted with 760 g of a 50 wt % ethanol aqueous solution, and after cooling to 5° C., diatomaceous earth was added and the mixture was filtered to prepare a crude spilanthol solution 1 with a spilanthol concentration of 50 ppm (w/w).
With 100 g of the Spilanthes acmella crude extract of Production Example 1 (spilanthol content: 12.4%) there was mixed 50 g of fatty acid triglycerides, and a reduced pressure thin-film distillation apparatus was used for distillation at a degree of vacuum of 4-5 Pa and a vaporization surface temperature of 120° C., to obtain 12.3 g of distillate. Yield: 12.3%. Spilanthol content: 67.3 wt %.
A 0.1 g portion of the distillate was diluted with 1346 g of a 50 wt % ethanol aqueous solution, and after cooling to 5° C., diatomaceous earth was added and the mixture was filtered to prepare a crude spilanthol solution 2 with a spilanthol concentration of 50 ppm (w/w).
A 300 g portion of dried flower heads of Spilanthes acmella was subjected to reflux extraction for 1 hour with 3200 g of 95 vol % ethanol. The extract solution was cooled, the solid and liquid portions were separated, and diatomaceous earth was added for filtration. The filtration was concentrated under reduced pressure to remove the ethanol, and then 300 g of water was added and extraction was performed three times with 300 ml of hexane. The extracted hexane layers were combined and concentrated under reduced pressure for removal of the hexane to obtain 8.4 g of a crude extract. Yield: 2.8% (spilanthol content: 9.5%).
An 8.4 g portion of the crude extract was fractionated (elution with n-hexane:ethyl acetate=8:2) by silica gel column chromatography (200 g of silica gel, φ5 cm), and the spilanthol fraction (Rf value=0.2-0.3, n-hexane:ethyl acetate=7:3) was separated off and the solvent was distilled off under reduced pressure to obtain 2.76 g of a crude spilanthol fraction 1. The crude spilanthol fraction 1 was then subjected to simple distillation and purification (180° C.) using a Kugel-Rohr distilling apparatus under reduced pressure (0.1 mmHg) to obtain 0.98 g of a crude spilanthol fraction 2. Yield: 0.33% (spilanthol content: 41.9%).
An 0.98 g portion of the crude spilanthol fraction was further fractionated (elution with n-hexane:ethyl acetate=95:5-90:10) by silica gel column chromatography (200 g of silica gel, (115 cm), and then the spilanthol fraction (Rf value=0.2, n-hexane:ethyl acetate=7:3) was separated off and the solvent was distilled off under reduced pressure to obtain 0.52 g of purified spilanthol. Yield: 0.17%. Spilanthol content: 98 wt %. The spilanthol structure was confirmed by proton and 13C NMR measurement in comparison with the known published data.
A 0.104 g portion of the purified spilanthol was diluted with 2000 g of a 50 wt % ethanol solution to prepare a purified spilanthol solution with a spilanthol concentration of 50 ppm (w/w).
