Description

[Technical Field]

[0001] The present invention relates to a carbonated alcoholic beverage, particularly a carbonated alcoholic beverage that combines the drinking taste of carbonation with the inherent flavor and taste of an alcoholic beverage (alcohol), and a method for improving the drinking taste and flavor of a carbonated alcoholic beverage. [Background technology]

[0002] Carbonated alcoholic beverages can provide a stimulating, refreshing or cool feeling due to the carbonation, as well as a flavor (aroma or taste) due to flavoring, and in recent years, there has been growing interest and preference for strongly carbonated alcoholic beverages with a high carbon dioxide content.

[0003] Bottled carbonated alcoholic beverages, such as shochu highballs (chuhai) and carbonated cocktail drinks, are produced by adding carbon dioxide (water) to drinking alcohol or by filling the drink with carbon dioxide gas. Distilled alcohol is mainly used as the drinking alcohol used in (bottled) carbonated alcoholic beverages because it has a mild flavor and is inexpensive.

[0004] In order to meet consumer preferences, carbonated alcoholic beverages are required to achieve the inherent flavors and aromas of alcoholic beverages (alcoholic drinks), such as a mellow taste, richness, umami, and a matured feel. However, since brewed alcohol, which is widely used in carbonated alcoholic beverages, has almost no inherent flavor or aroma of its own, it has sometimes been impossible to impart a sufficient flavor or aroma derived from alcoholic beverages (alcoholic drinks) to carbonated alcoholic beverages.

[0005] In response to this, Japanese Patent Laid-Open Publication No. 2002-330735 (Patent Document 1) proposes that adding water-soluble dietary fiber such as indigestible dextrin to an alcoholic beverage can impart a mellow (creamy) and rich flavor. However, the present inventors have confirmed that when water-soluble dietary fiber is added to a carbonated alcoholic beverage, it becomes difficult to sense the stimulating, refreshing, and cool flavors of carbonation.

[0006] Of course, it was thought that increasing the carbon dioxide pressure in a carbonated alcoholic beverage containing water-soluble dietary fiber would be sufficient to maintain or improve the drinking taste, such as the stimulating, refreshing, or cool sensation caused by the carbon dioxide. However, in reality, in the case of a carbonated alcoholic beverage containing water-soluble dietary fiber, simply increasing the carbon dioxide pressure improved the drinking taste caused by the carbonation to a certain extent, but it was confirmed that sensory or preference aspects such as mellowness (creamyness) and richness were reduced, and as a result, the inherent flavor or taste of an alcoholic beverage (alcohol), such as mellowness, richness, umami, and a matured flavor, were not fully achieved. In other words, it was recognized that in a carbonated alcoholic beverage containing water-soluble dietary fiber, there is a trade-off between improving the drinking taste caused by carbonation and improving the inherent flavor and aroma of an alcoholic beverage (alcohol).

[0007] In addition, Patent Document 2 (JP 2006-166870 A) proposes a method of enhancing or maintaining the carbonation sensation of a carbonated beverage by adding spilanthol (a pungent component contained in plants such as Amanita acmella of the Asteraceae family) to the carbonated beverage.Furthermore, Patent Document 3 (JP 2013-94129 A) proposes a method of enhancing the carbonation sensation of a carbonated beverage by adding hydroxy acid esters (bitter components).

[0008] However, when the specific ingredients proposed in Patent Documents 2 and 3 were added to carbonated alcoholic beverages, although the carbonation stimulant effect was indeed improved, the carbonated alcoholic beverages were given the pungent taste and bitterness derived from the specific ingredients, and the original drinking taste and flavor of the carbonated alcoholic beverages were not fully achieved. However, we were unable to achieve this goal. [Prior art documents] [Patent documents]

[0010] Therefore, there is still a demand for the development of carbonated alcoholic beverages that synergistically combine the stimulating, refreshing, and cool taste of carbonation with the flavor and aroma of alcoholic beverages (alcoholic drinks), such as mellowness, richness, umami, and a sense of maturity, at a high level.

[0011] Therefore, the present inventors have come to the realization that it is necessary to develop a carbonated alcoholic beverage that synergistically combines the characteristics of both the drinking taste due to carbonation and the inherent flavor and taste of alcoholic beverages (alcoholic beverages) at a high level. The present invention was made based on this realization.

DETAILED DESCRIPTION OF THE INVENTION

[0014] [Definition] (1,1-diethoxyethane) "1,1-diethoxyethane" has the structural formula [CH3CH(OC2H5)2] and a molecular weight of 118.17. "1,1-diethoxyethane" is a chain organic compound represented by the following chemical formula (1), and is also known as acetal. "1,1-diethoxyethane" is a colorless, transparent liquid with a fruity fragrance. [ka]

[0015] (Alcoholic beverages) "Alcoholic beverages" are defined in the Liquor Tax Act as "drinks with one or more alcoholic beverages," and are also treated as foods under the Food Sanitation Act, and are subject to that law. "Alcoholic beverages" include brewed alcohol, distilled alcohol, other alcoholic beverages, and mixtures of one or more of these. As defined in the Liquor Tax Act, "alcohol content" refers to the volume of ethyl alcohol contained in a 100% original volume at a temperature of 15 degrees. "Alcohol content" refers to the volume concentration of ethanol in an alcoholic beverage expressed as a percentage (%).

[0016] (edible alcohol, brewer's alcohol) Edible alcohol refers to alcohol (ethanol) for consumption as defined by the Food Sanitation Act, etc. Distilled alcohol refers to alcohol obtained by fermenting starchy materials such as rice, sweet potato, and corn, or sugar-containing materials such as molasses, and distilling it in a continuous still.

[0017] (Pure alcohol equivalent) "Pure alcohol equivalent" refers to the concentration (mg / l) (= ppm) of a specific component (mg) contained in an alcoholic beverage (1 liter) divided by the alcohol content (v / v%) of the beverage, converted into a value per alcohol content (v / v%). For example, if a specific alcoholic beverage (alcohol content 10 (v / v%) contains 50 ppm of a specific aroma component, the content of the specific aroma component, converted into pure alcohol, is [50 ppm ÷ (10 ÷ 100)] = 500 ppm.

[0018] (gas volume) "Gas volume" refers to the ratio of the volume of carbon dioxide dissolved in a bottled carbonated alcoholic beverage under standard conditions to the volume of the beverage (using GV as the unit). In practice, 1 GV gas volume is obtained when 1 liter of carbon dioxide gas is dissolved in 1 liter of liquid under standard conditions (1 atmosphere, 25°C). "Gas volume" is calculated by dividing a carbonated alcoholic beverage sample into After stabilizing the pressure (1 atmosphere, 25°C), attach a gas pressure gauge, open the stopcock once to release the gas (sniff), immediately close the stopcock and shake vigorously, and the value when the pressure becomes constant can be obtained.

[0019] (Sweetness) "Sweetness" is a numerical value determined by the ratio of concentrations showing the same sweetness intensity as sucrose at a specific concentration, using sucrose as the standard substance, or the ratio to the threshold value of sucrose determined under other identical conditions. Specifically, when the sweetness of sucrose at a specific concentration is set to "1," the sweetness of the substance being measured can be expressed as "1" under the same measurement conditions. For example, if the sweetness is the same, the sweetness of the substance being measured can be expressed as "1." Specifically, if substance A has a sweetness of "10," this means that the sweetness of sucrose at a specific concentration is equivalent to that of substance A at 1 / 10 its concentration. "Sweetness" is the value listed in "A Comprehensive Guide to Sweeteners" (published May 1990) by the Sugar Refining Industry Association and "All About Sucralose, the High-Intensity Sweetener" (published May 2003) by Korin Co., Ltd.

[0020] [Carbonated alcoholic beverages] As one aspect of the present invention, we propose a carbonated alcoholic beverage that contains a specific content of 1,1-diethoxyethane, water-soluble dietary fiber, edible alcohol, and carbon dioxide as essential ingredients.

[0021] (1,1-diethoxyethane) The carbonated alcoholic beverage contains a specific amount of 1,1-diethoxyethane. By including a specific amount of 1,1-diethoxyethane together with water-soluble dietary fiber, it is possible to synergistically achieve a high level of both the stimulating, refreshing, and refreshing taste of carbonation and the inherent flavor and aroma of alcoholic beverages (alcoholic drinks), such as mellowness, richness, umami, and a matured feel. Furthermore, by suppressing, improving, or reducing the bitterness, spiciness, and spiciness derived from alcohol, it is possible to impart sweetness, richness, and a rich, full-bodied feel to the carbonated alcoholic beverage. As a result, it is possible to fully exhibit and enhance the drinking taste due to the carbonation, to bring out the inherent flavor and taste of alcoholic beverages (alcoholic drinks), and to achieve an excellent aftertaste. As a result, it is possible to provide a carbonated alcoholic beverage that achieves a high level of carbonation, achieves the inherent flavor and aroma of alcoholic beverages (alcoholic drinks), suppresses the bitterness, spiciness, and spiciness derived from alcohol, and has an excellent aftertaste.

[0022] <Content> The content of 1,1-diethoxyethane in carbonated alcoholic beverages is, as a lower limit, 20 ppm or more, and preferably 100 ppm or more, calculated as pure alcohol, and as an upper limit, 5000 ppm or less, and more preferably 2000 ppm or less, calculated as pure alcohol.

[0023] When the 1,1-diethoxyethane content is less than 20 ppm in terms of pure alcohol, the effect of combining the carbonated taste with the flavor of an alcoholic beverage (alcohol) cannot be fully demonstrated, and when it exceeds 5000 ppm, the cosmetic-like scent specific to 1,1-diethoxyethane is strongly felt, resulting in a low overall evaluation of the taste as a beverage.

[0024] Therefore, by ensuring that the content of 1,1-diethoxyethane is within the above range, it is possible to achieve a high level of balance between the drinking taste due to the carbonation and the inherent flavor and taste of the alcoholic beverage (alcohol), while masking the bitterness and other tastes derived from alcohol and achieving an excellent aftertaste.

[0025] 1,1-diethoxyethane is preferably used in the form of a plant or the like containing a significant amount of 1,1-diethoxyethane, or an extract or chemically synthesized product from such a plant or the like. 1,1-diethoxyethane may also be chemically synthesized by a method acceptable in food chemistry. The extraction or chemical synthesis is carried out using a method acceptable under the Food Sanitation Act.

[0026] (Water-soluble dietary fiber) Carbonated alcoholic beverages contain water-soluble dietary fiber. By adding water-soluble dietary fiber to carbonated alcoholic beverages, it is possible to impart a mellow (creamy) and rich flavor, and it is also possible to exert pharmacological effects such as lowering blood cholesterol, improving blood sugar levels, and inhibiting fat absorption in the small intestine. In particular, in carbonated alcoholic beverages containing water-soluble dietary fiber, by combining them with a specific content of 1,1-diethoxyethane, it is possible to significantly resolve the problems (trade-offs) of the prior art and synergistically achieve both the drinking taste of the carbonation and the inherent flavor and aroma of alcohol (alcohol).

[0027] The term "water-soluble dietary fiber" refers to water-soluble polymeric components, primarily polysaccharides, that are indigestible by human digestive enzymes. The water-soluble dietary fiber may be, for example, one or a mixture of two or more selected from the group consisting of indigestible dextrin, polydextrose, isomaltodextrin, pectin, alginic acid, laminarin, hydrolyzed guar gum, glucomannan, carrageenan, and fucoidin, and is preferably indigestible dextrin and / or polydextrose.

[0028] The "resistant dextrin" may be a reduced product of resistant dextrin produced by hydrogenation (reduced resistant dextrin), or a commercially available product. "Polydextrose" is an artificially synthesized product, for example, obtained by mixing glucose, sorbitol, and citric acid and polymerizing them at high temperature, or a commercially available product.

[0029] <Content> The content of water-soluble dietary fiber is not particularly limited and can be determined as appropriate, but the upper limit is preferably 80 g / L or less, more preferably 50 g / L or less, based on the total amount of the carbonated alcoholic beverage. By setting the upper limit of the water-soluble dietary fiber content within the above range, the effect of adding a specific amount of 1,1-diethoxyethane can be more effectively achieved.

[0030] The concentration of water-soluble dietary fiber in a beverage can be calculated based on the raw materials used in production, or it can be measured using high-performance liquid chromatography (enzyme-HPLC), which is a method for analyzing dietary fiber as described in Eishin No. 13, April 26, 1999 ("Methods for analyzing nutritional components, etc. in the Nutrition Labeling Standards").

[0031] <Alcohol content> The carbonated alcoholic beverage preferably has an alcohol content of at least 1 v / v%, preferably at least 3 v / v%, and at most 20 v / v%, preferably at most 10 v / v%, based on the total volume of the carbonated alcoholic beverage. By having the alcohol content within the above range, the effects of adding a specific amount of 1,1-diethoxyethane can be more effectively achieved.

[0032] (carbonated water) Carbonated water can be any carbonated water commonly produced in the beverage industry. Carbonated water can generally be produced by a method called carbonation, in which a carbonated alcoholic beverage is cooled to below room temperature as needed, and carbon dioxide gas is pressurized into the beverage. In the present invention, after preparing an alcoholic beverage, the carbonated alcoholic beverage can be produced by the carbonation method. Carbonated water can also be prepared by dissolving a carbonate salt (e.g., sodium carbonate, potassium carbonate, calcium carbonate, magnesium carbonate) in drinking water to produce carbonated water. This prepared carbonated water can also be further subjected to the carbonation method.

[0033] <Gas volume: GV> The gas volume of a carbonated alcoholic beverage can be specified as appropriate, but the lower limit is 2.0 GV or more, preferably 2.5 GV or more, and the upper limit is 3.5 GV or less, preferably 3.3 GV or less, and more preferably 3.0 GV or less. By ensuring that the "gas volume: GV" value is within the above range, the effect of adding a specific amount of 1,1-diethoxyethane can be more effectively achieved.

[0034] (optional ingredient) Carbonated alcoholic beverages may contain optional ingredients, as needed. These optional ingredients may include colorants, vegetable juices, fruit juices, extracts, flavorings, sweeteners, acidulants, pH adjusters, antioxidants, preservatives, vitamins, umami components, dietary fiber, stabilizers, and emulsifiers. These ingredients should be those specified in the guidelines established by the Ministry of Health, Labor, and Welfare, the Consumer Affairs Agency, and other organizations, as well as in related laws and regulations (such as the Food Sanitation Act).

[0035] <sweetener> Carbonated alcoholic beverages may contain sweeteners.

[0036] Sweeteners include carbohydrate-based sweeteners and non-carbohydrate-based sweeteners, such as sugars, sugar alcohols, and high-intensity sweeteners. "Carbohydrates" refers primarily to carbohydrates excluding dietary fiber, and "sugars" refers primarily to carbohydrates contained in monosaccharides and disaccharides.

[0037] Examples of "carbohydrate sweeteners" include sugars and sugar alcohols, and specifically include one or a mixture of two or more selected from the group consisting of glucose (grape sugar), galactose, mannose, fructose (fruit sugar), sucrose (cane sugar), lactose (milk sugar), lactose (maltose), high fructose corn syrup, and starch syrup, isomerized sugar, isomaltooligosaccharides, fructooligosaccharides, galactooligosaccharides, xylooligosaccharides, lactoferrin oligosaccharides, soybean oligosaccharides, raffinose, trehalose, sorbitol, mannitol, maltitol, reduced starch syrup, reduced palatinose, xylitol, and erythritol. The "non-sugar sweetener" is one or a mixture of two or more selected from the group consisting of natural sweeteners (stevia, licorice (glycyrrhizin), etc.) and artificial sweeteners (saccharin, aspartame, acesulfame potassium, sucralose, etc.). Examples of "high-intensity sweeteners" include aspartame, acesulfame potassium, and chitosan. The sugar is a mixture of one or more sugars selected from the group consisting of cylitol, disodium glycyrrhizinate, saccharin, calcium saccharin, sodium saccharin, sucralose, neotame, arabinose, licorice extract, xylose, stevia, thaumatin, swingle extract, rhamnose, and ribose. Examples of "high-intensity sweeteners" based on their "sweetness" include glycoside-based sweeteners such as stevioside (sweetness level 150), glycyrrhizin (sweetness level 300), thaumatin (sweetness level 2000), and monellin (sweetness level 3000); amino acid-based sweeteners such as aspartame (sweetness level 200) and neotame (sweetness level 10,000); saccharin sodium (sweetness level 500), cyclamate (sodium cyclamate) (sweetness level 30-80), acesulfame potassium (sweetness level 200), and sucralose (sweetness level 600).

[0038] <Sweetness> The sweetness index of the carbonated alcoholic beverage is 3.0 or less, preferably 2.0 or less, and more preferably 1.0 or less. By having the sweetness index within the above range, the effect of adding a specific amount of 1,1-diethoxyethane can be more effectively exhibited.

[0039] <Vegetable or fruit juice: Not included> In a preferred embodiment of the present invention, the carbonated alcoholic beverage may contain vegetable juice or fruit juice, but is preferably one that does not contain vegetable juice or fruit juice.

[0040] <Acidifier> Specific examples of acidulants include adipic acid, citric acid, trisodium citrate, glucono-delta-lactone, gluconic acid, potassium gluconate, sodium gluconate, succinic acid, monosodium succinate, disodium succinate, sodium acetate, DL-tartaric acid, L-tartaric acid, sodium DL-tartrate, sodium L-tartrate, carbon dioxide, lactic acid, sodium lactate, glacial acetic acid, fumaric acid, monosodium fumarate, DL-malic acid, sodium DL-malate, phosphoric acid, and salts thereof (potassium salts, sodium salts). Acidulants can also be used as pH adjusters.

[0041] (Physical properties of carbonated alcoholic beverages) pH The pH of the carbonated alcoholic beverage is 2.0 or higher, preferably 2.5 or higher, and 5.0 or lower, preferably 4.0 or lower. By maintaining the pH of the clear beverage within this range, it is possible to impart ease of drinking and sweetness to the carbonated alcoholic beverage, as well as to impart long-term storage stability and antifungal or antibacterial properties to the carbonated alcoholic beverage. The pH value can be measured, for example, in accordance with JIS Z 8802:2011, and may be measured using a pH meter (for example, the TTT-510 manufactured by DKK-TOA Corporation).
