Description
DESCRIPTION OF EMBODIMENTS
[0015] Hereinafter, a beverage and a method of the present invention will be described.
[0016] The ppm as used herein means ppm by weight/volume (w/v) unless otherwise specified, and this is synonymous with mg/L. If a substance is described merely as alcohol herein, it means ethanol unless otherwise specified, and does not mean an aliphatic alcohol having 4 or 5 carbon atoms.
(Aliphatic Alcohol Having 4 or 5 Carbon Atoms)
[0017] The beverage of the present invention contains an aliphatic alcohol having 4 or 5 carbon atoms. The beverage may contain one of the aliphatic alcohols, or may contain two or more of the aliphatic alcohols. The total content of the aliphatic alcohol in the beverage is 1 to 300 ppm, preferably 1 to 200 ppm, and more preferably 3 to 80 ppm. Although having a low alcohol content or containing no alcohol, the beverage having a flavor typical of liquor can be provided due to this characteristic.
[0018] Examples of the aliphatic alcohol include 2-methyl-1-propanol, 1-butanol, 3-methyl-1-butanol, 2-methyl-1-butanol, 1-pentanol, and 2-pentanol. The aliphatic alcohol is preferably selected from the group consisting of 2-methyl-1-propanol, 3-methyl-1-butanol, and 2-methyl-1-butanol, and is more preferably 3-methyl-1-butanol.
[0019] The content of the aliphatic alcohol in the beverage of the present invention may be measured by any known method such as GC-MS or HPLC, and can be measured, for example, by GC-MS under the following conditions.

[0033] The beverage of the present invention is a low-alcohol beverage or a non-alcohol beverage, in other words, the beverage of the present invention has a low alcohol content or contains no alcohol. The alcohol content of the beverage of the present invention is specifically less than 3 v/v %. The content may be 2.0 v/v % or less, 1.0 v/v % or less, or 0.00 v/v %.
[0034] The non-alcohol beverage of the present invention does not exclude a beverage containing alcohol in so minute an amount as to be undetectable. The alcohol content of the non-alcohol beverage of the present invention is preferably 0.00 v/v %. In description for confirmation, 0.00 v/v % also includes numerical values such as 0.001 v/v % which can be rounded off to be 0.00 v/v %.
[0035] Examples of the non-alcohol beverage include alcohol-taste beverages having tastes like alcoholic beverages. Examples of the alcohol-taste beverage include, but not limited to, beer-taste beverages, chuhai-taste beverages, non-alcohol cocktails, sour-taste beverages, wine-taste beverages, and sake-taste beverages. When these beverages are described in more detail by giving chuhai-taste beverages, non-alcohol cocktails, and sour-taste beverages as examples, these beverages refer to beverages that are non-alcohol beverages and achieve flavors like chuhais (that mean alcoholic carbonated beverages in which distilled liquor is diluted with other beverages such as water, soft drinks, and teas with respect to the present invention), cocktails (that mean beverages each containing a spirit or a liqueur, acidulous fruit juice such as a citrus fruit, a sweet component, and optionally carbon dioxide with respect to the present invention), and sours (that mean beverages each containing a spirit, acidulous fruit juice such as a citrus fruit, a sweet component, and carbon dioxide with respect to the present invention) as the models.
[0036] Alcohol may be incorporated into the low-alcohol beverage of the present invention by any means. The low-alcohol beverage of the present invention typically contains alcohol raw material, and therefore contains alcohol.
[0037] Examples of the alcohol raw material include, but not particularly limited to, for example spirits (rum, vodka, gin, tequila, or the like), liqueurs, whiskey, brandy, and shochu. Furthermore, the alcohol raw material may be brewage such as beer or wine. These alcohol raw materials can be used alone or in combination.
[0038] The type of the low-alcohol beverage of the present invention may be, but not particularly limited to, preferably a chuhai, a cocktail, and a sour.
[0039] The alcohol content of the beverage herein can be measured by any known method, for example, with a vibrating densimeter. Specifically, carbon dioxide is removed from the beverage by filtration or ultrasonic waves as needed to prepare a sample. The sample is subjected to steam distillation. Then, the density at 15 C. of the resulting distillate is measured and converted to an alcohol content according to Table 2 Conversion among Alcohol Content, Density (15 C.) and Specific Gravity (15/15 C.) which is annexed to the Official Analysis Method of the National Tax Agency in Japan (National Tax Agency Directive No. 6 in 2007, revised on Jun. 22, 2007).

EXAMPLES
[0052] Although the present invention will be described based on Example hereinafter, the present invention is not limited to these Examples.
(Test Example 1) Influence of Aliphatic Alcohol Having 4 or 5 Carbon Atoms
[0053] The liquor-like taste imparting effect of the aliphatic alcohol having 4 or 5 carbon atoms was examined.
[0054] To an aqueous solution having an alcohol content (Alc.) of 0 v/v %, 3-methyl-1-butanol was added at the contents shown in the following table to prepare various samples.
[0055] Specifically, if the aliphatic alcohol content was 1 ppm, 0.1 mg of 3-methyl-1-butanol was weighed and added to 50 ml of ion-exchange water, the mixture was well stirred, followed by the visual confirmation that undissolved 3-methyl-1-butanol did not remain, ion-exchange water was further added to adjust the total volume to 100 ml with a volumetric flask, and this was used as a beverage model solution (sample beverage). Other beverage model solutions were prepared in the same way so that the contents were as shown in the following table. As a control, ion-exchange water (Sample No. 1) was used.
[0056] Four special panelists sensorily evaluated whether the effects of imparting a liquor-like taste (thickness typical of liquor; brewage-like depth, fullness, and aftertaste; and slight bitterness) in the obtained various samples were felt on a scale of one to six with felt very strongly evaluated as 6 points and not felt evaluated as 1 point. The evaluation results of the four panelists were totaled. If the average thereof was 1 or more and less than 2, the sample was evaluated as . If the average thereof was 2 or more and less than 3, the sample was evaluated as . If the average thereof was 3 or more and less than 4, the sample beverage was evaluated as +. If the average thereof was 4 or more and less than 5, the sample was evaluated as ++. If the average thereof was 5 or more, the sample was evaluated as +++.
[0057] The panelists established the common understanding of the relationship between the scores and the tastes beforehand to reduce the difference in evaluation between the individuals, and then performed the evaluation tests. The following table shows the results of the test.

[0058] A liquor-like taste was imparted by adding 3-methyl-1-butanol, and preferable results were obtained in a particular content range.
(Test Example 2) Influence of GABA
[0059] GABA was added to the beverage model solution Sample No. 6, prepared in Test Example 1 and containing 3-methyl-1-butanol at a content of 10 ppm, in various amounts to prepare samples as the beverage model solutions, and the effect of increasing a liquor-like taste with GABA was examined. The amount of GABA added is as shown in the following table.
[0060] The samples were subjected to sensory evaluation.
[0061] Four special panelists sensorily evaluated whether the effects of increasing the liquor-like taste were felt in the samples on a scale of one to six with felt very strongly evaluated as 6 points and not felt evaluated as 1 point using the sample not containing GABA as a control (Ctrl). The evaluation results of the four panelists were totaled. If the average thereof was 1 or more and less than 2, the sample was evaluated as . If the average thereof was 2 or more and less than 3, the sample was evaluated as . If the average thereof was 3 or more and less than 4, the sample was evaluated as +. If the average thereof was 4 or more and less than 5, the sample was evaluated as ++. If the average thereof was 5 or more, the sample was evaluated as +++. In this case, the panelists also established the common understanding of the relationship between the scores and the tastes beforehand to reduce the difference in evaluation between the individuals, and then performed the evaluation tests.
[0062] The following table shows the results of the test. It was confirmed that GABA can increase the liquor-like taste.

(Test Example 3) Influence of GABA and Aliphatic Alcohol Having 4 or 5 Carbon Atoms
[0063] Various samples as beverage model solutions were prepared in accordance with the methods described in Test Examples 1 and 2. The amounts of aliphatic alcohol (3-methyl-1-butanol) and GABA added are as shown in the following table.
[0064] The samples were subjected to the sensory evaluation in the same way as in Test Example 2 to confirm the effect of increasing a liquor-like taste. It is a sample containing 3-methyl-1-butanol at a content of 1 or 200 ppm and no GABA that is used as a control. The results of the test are shown in the following table. A high effect of increasing the liquor-like taste was perceived in a particular range.

(Test Example 4) Influence of Type of Aliphatic Alcohol Having 4 or 5 Carbon Atoms
[0065] In the same way as the beverage model solution of Sample No. 6 in Test Example 1, containing 3-methyl-1-butanol at a content of 10 ppm, samples containing 2-methyl-1-butanol or 2-methyl-1-propanol instead of 3-methyl-1-butanol in the same amount were prepared. The obtained two samples were subjected to the sensory evaluation in the same way as in Test Example 1, and the same results as the result of Sample No. 6 were obtained. Accordingly, it was found that a wide variety of aliphatic alcohols having 4 or 5 carbon atoms lead to the same effect of imparting a liquor-like taste.
[0066] GABA was then added to those two samples in various amounts to examine the effect of increasing a liquor-like taste. The same sensory evaluation as in Test Example 2 led to the results shown in the following table.
