Advantages of the Invention

[0008] According to the present invention, it is possible to provide a container-packed alcoholic beverage set that allows one to enjoy different flavors.

Embodiments for Carrying Out the Invention

[0009] The container-packed alcoholic beverage set of the present invention has a plurality of container-packed alcoholic beverages in which a plurality of alcoholic beverages are packed in respective containers, and the plurality of container-packed alcoholic beverages include a container-packed alcoholic beverage A1 in which a first alcoholic beverage is packed in a container and a container-packed alcoholic beverage A2 in which a second alcoholic beverage is packed in a container. The first alcoholic beverage and the second alcoholic beverage described above are at least one selected from sake, continuously distilled shochu, single-distilled shochu, whiskey, fruit wine, or mixed alcoholic beverages obtained by diluting these alcoholic beverages with water. The first alcoholic beverage and the second alcoholic beverage are characterized in that they satisfy the relationship between formulas (1), (2), and (3), or the relationship between formulas (1), (4), and (5).

[0010] X 1 ≤X 2 ...Equation (1) Y 1 >Y 2 ...Equation (2) Y 10 ≥20X 1 -85...Equation (3) Y 1 <Y 2 ...Equation (4) Y 10 ≥20X 2 -85...Equation (5) In the formula, X 1 This is the alcohol concentration (vol%) of the first alcoholic beverage, Y 1 This is the isoamyl acetate concentration (μg / L) of the first alcoholic beverage, X 2 This is the alcohol concentration (vol%) of the second alcoholic beverage. Y 2 This is the isoamyl acetate concentration (μg / L) of the second alcoholic beverage. Y 10 This is the difference in isoamyl acetate concentration between the first alcoholic beverage and the second alcoholic beverage, and is a positive real number.

[0011] Since the first and second alcoholic beverages satisfying the above relationship can be sufficiently distinguished by their flavor differences, the packaged alcoholic beverage set of the present invention can be a packaged alcoholic beverage set that allows consumers to enjoy the difference in taste.

[0012] In the packaged alcoholic beverage set of the present invention, it is preferable that each packaged alcoholic beverage is sealed within its respective container.

[0013] In the packaged alcoholic beverage set of the present invention, the first alcoholic beverage and the second alcoholic beverage are at least one selected from sake, continuously distilled shochu, single-distilled shochu, whiskey, fruit wine, or mixed alcoholic beverages obtained by diluting these alcoholic beverages with water. In these alcoholic beverages, isoamyl acetate is one of the important components that characterize the flavor. Preferably, the sake, continuously distilled shochu, single-distilled shochu, whiskey, and fruit wine are alcoholic beverages other than those to which flavorings have been added.

[0014] The above-mentioned alcoholic beverages are subject to restrictions on the ingredients that can be used under the Liquor Tax Law and various related laws and regulations (for example, the Liquor Tax Enforcement Order) and circulars, and the addition of flavorings and other substances generally permitted as food additives is not allowed. Therefore, it is preferable that the above-mentioned sake, continuously distilled shochu, single-distilled shochu, whiskey, and fruit wine are those defined under the Liquor Tax Law (particularly the Liquor Tax Law of Japan).

[0015] Given that isoamyl acetate is particularly important as a component that characterizes the flavor, in the packaged alcoholic beverage set of the present invention, the first alcoholic beverage and the second alcoholic beverage are preferably at least one selected from sake, continuously distilled shochu, single-distilled shochu, whiskey, or mixed alcoholic beverages obtained by diluting these alcoholic beverages with water, and more preferably sake. In the packaged alcoholic beverage set of the present invention, the first alcoholic beverage and the second alcoholic beverage are preferably of the same type, and more preferably both the first and second alcoholic beverages are sake.

[0016] Sake can be any beverage made by fermenting rice, rice koji, and water with yeast, but it is preferable that it be sake as defined by the Liquor Tax Law (especially the Liquor Tax Law of Japan). In the Liquor Tax Law and related laws and regulations (for example, the Liquor Tax Law Enforcement Order) and circulars, the ingredients that can be used for sake are limited to rice, rice koji, water, sake lees, brewing alcohol, shochu, and certain organic acids, and the addition of flavorings and other substances that are generally permitted as food additives is not allowed. Furthermore, the amount and use of enzyme preparations are also limited.

[0017] Sake may be ordinary sake, or if it is taxed by the national government, it may be a specially designated sake that meets the "Standards for Labeling the Manufacturing Method and Quality of Sake" (standards for labeling alcoholic beverages as stipulated in the "Act on the Preservation of Liquor Tax and Liquor Industry Associations, etc."), such as ginjo-shu, daiginjo-shu, junmai-shu, junmai ginjo-shu, junmai daiginjo-shu, tokubetsu junmai-shu, honjozo-shu, or tokubetsu honjozo-shu.

[0018] In the packaged alcoholic beverage set of the present invention, the alcohol concentration of both the first and second alcoholic beverages is preferably 5 vol% or higher, more preferably 10 vol% or higher, even more preferably 10 to 22 vol%, and particularly preferably 10 to 20 vol%, for the reason that the effects of the present invention are more significantly exhibited. In this specification, the alcohol concentration of the alcoholic beverage refers to the ethanol concentration of the alcoholic beverage.

[0019] In the packaged alcoholic beverage set of the present invention, the difference in alcohol concentration between the first alcoholic beverage and the second alcoholic beverage is preferably 12 vol% or less, more preferably 10 vol% or less, and even more preferably 5 vol% or less, because this allows for a more pronounced recognition of the difference in flavor and enables a more pronounced effect of the present invention.

[0020] The isoamyl acetate concentration of the first alcoholic beverage and the second alcoholic beverage is preferably 200 mg / L or less, more preferably 150 mg / L or less, and even more preferably 50 mg / L or less.

[0021] The difference in isoamyl acetate concentration between the first alcoholic beverage and the second alcoholic beverage, i.e., Y in equations (3) and (5). 10 The isoamyl acetate concentration in alcoholic beverages can be measured, for example, by appropriately diluting the sample and using solid-phase microextraction-gas chromatography-mass chromatography (SPME-GC-MS) or headspace gas chromatography.

[0022] In the packaged alcoholic beverage set of the present invention, the amount of acetaldehyde leached from the container of packaged alcoholic beverage A1 and packaged alcoholic beverage A2 after being stored for 72 hours at room temperature (23°C) is preferably 0.1 ppm or less, and more preferably 0.06 ppm or less. If the amount of acetaldehyde leached from the container is 0.1 ppm or less, the flavor of the alcoholic beverage is less likely to be inhibited, and the subtle differences in flavor between the alcoholic beverages can be perceived more clearly.

[0023] The amount of acetaldehyde eluted from the container can be measured by methods such as high-performance liquid chromatography. For example, it can be measured by the following method: Take 1.0 mL of the solution from the container and add 0.2 mL of a 0.1% 2,4-dinitrophenylhydrazine phosphate solution. After 30 minutes, filter the solution through a 0.45 μm membrane filter and measure the filtrate using high-performance liquid chromatography (Agilent 1200 Infinity, manufactured by Agilent Technologies, Inc.).

[0024] The packaged alcoholic beverage set of the present invention may further include, in addition to the packaged alcoholic beverage A1 and packaged alcoholic beverage A2 described above, a packaged alcoholic beverage A3 in which a third alcoholic beverage is packaged in a container.

[0025] The packaged alcoholic beverage A3 may consist of only one type or two or more types.

[0026] Examples of the third type of alcoholic beverage include those mentioned above, and it is preferable that it be the same type of alcoholic beverage as the first or second alcoholic beverage. In one preferred embodiment, the first, second, and third alcoholic beverages are all sake.

[0027] The alcohol concentration of the third alcoholic beverage is preferably 1 to 50 vol%, more preferably 5 to 25 vol%, and even more preferably 7 to 22 vol%.

[0028] In the case of packaged alcoholic beverages, there are no particular limitations on the material of the container used to package the alcoholic beverage. For example, it may be glass, resin, paper, ceramic, metal, or a combination thereof. Examples of container types include glass bottles, cans, plastic bottles, paper containers, and pouches. Preferably, the container is a sealed container with a drinking spout or pouring spout.

[0029] The container volume is preferably 20 to 125 mL, more preferably 30 to 125 mL, and even more preferably 30 to 80 mL.

[0030] Alcoholic beverages, after opening, are prone to flavor deterioration due to oxidation and other factors, as some flavor components, such as aroma compounds, are removed along with the alcohol. Furthermore, when pouring into a glass or other drinking container, aroma compounds may be removed during the pouring process, preventing the full appreciation of the beverage's original flavor. This tendency becomes particularly pronounced with high-alcohol beverages (especially sake), as small amounts are often poured into drinking containers repeatedly. Alcoholic beverages with a volume of 10-90mL are relatively small, reducing food waste and the amount of pure alcohol consumed during taste tests. Moreover, they can be consumed quickly, allowing for a full appreciation of the beverage's original flavor.

[0031] The volume of each alcoholic beverage included in a packaged alcoholic beverage set is preferably 10-90 mL, more preferably 20-80 mL, and even more preferably 40-60 mL, from the viewpoint of ease of consumption.

[0032] The total volume of alcoholic beverages included in a packaged alcoholic beverage set (if the packaged alcoholic beverage set contains only packaged alcoholic beverage A1 and packaged alcoholic beverage A2, this is the total volume of the first alcoholic beverage and the second alcoholic beverage; if the packaged alcoholic beverage set also includes packaged alcoholic beverage A3, this is the total volume of the first alcoholic beverage, the second alcoholic beverage and the third alcoholic beverage) is preferably 270 mL or less, more preferably 240 mL or less, and even more preferably 180 mL or less, from the viewpoint of ease of consumption.

[0033] From the viewpoint of the health effects of drinking, the total amount of pure alcohol in each alcoholic beverage included in a set of packaged alcoholic beverages is preferably 40g or less, more preferably 30g or less, and even more preferably 20g or less.

[0034] In this specification, the amount of pure alcohol is defined as the value shown below. Amount of pure alcohol (g) = Volume of alcoholic beverage (mL) × (Alcohol concentration of alcoholic solution (vol%) / 100) × 0.8

[0035] One preferred embodiment of the packaged alcoholic beverage set of the present invention is a configuration in which each packaged alcoholic beverage is stacked on top of the others. In this embodiment, the container is preferably a sealable container having a drinking spout, a pouring spout, or a wide opening. The type of container is preferably a rigid or semi-rigid container, and examples include cans, plastic cups, portion packs, etc. Furthermore, in this embodiment, it is preferable that each container of alcoholic beverage is stacked and that each container of alcoholic beverage is wrapped in a packaging film such as shrink film to form a single unit.

[0036] Another preferred embodiment of the packaged alcoholic beverage set of the present invention is a configuration in which a plurality of packaged alcoholic beverages are arranged in a series, each containing one of the alcoholic beverages in a pouch container. [Examples]

[0037] The present invention will be described in more detail below with reference to examples. The materials, amounts used, proportions, processing content, and processing procedures shown in the following examples can be modified as appropriate, as long as they do not depart from the spirit of the present invention. Therefore, the scope of the present invention is not limited to the specific examples shown below.

[0038] <Method for preparing sample solutions> Alcohol solutions (blank solutions) with alcohol concentrations of 5-20 vol% were prepared by dissolving ethanol for precision analysis in ultrapure water (milli-Q water). Sample solutions were prepared by dissolving 1-520 μg / L of isoamyl acetate in each alcohol solution (blank solution). Alcohol solutions of each alcohol concentration without isoamyl acetate (blank alcohol solutions) and alcohol solutions containing a predetermined amount of isoamyl acetate (sample solutions) were each poured into a 103 mL polyethylene terephthalate cup at least one minute before the test. The amount of acetaldehyde leached from the cup used in the test was confirmed as follows: 15 mL of ultrapure water was poured into the cup and covered with a glass dish. After 72 hours of storage at room temperature (23°C), the amount of acetaldehyde leached from the cup was 0.1 ppm or less, and it was confirmed that this did not affect the evaluation. The amount of acetaldehyde leached was measured by the following method. 1.0 mL of the solution in the cup was taken, and 0.2 mL of a 0.1% 2,4-dinitrophenylhydrazine phosphate solution was added. After 30 minutes, the solution was filtered through a 0.45 μm membrane filter, and the filtrate was measured using high-performance liquid chromatography (Agilent 1200 Infinity, Agilent Technologies, Inc.).

[0039] <Testing Method> Two types of alcohol solutions were prepared, and a sensory evaluation was conducted using the three-point discrimination method. Three alcohol solutions were prepared in total, each with the same alcohol concentration, containing a predetermined amount of isoamyl acetate (sample solution) and not containing isoamyl acetate (blank alcohol solution). (For example, one alcohol solution with an alcohol concentration of 10 vol% and no isoamyl acetate (blank alcohol solution), and two alcohol solutions with an alcohol concentration of 10 vol% and an isoamyl acetate concentration of 90 μg / L (sample solution)). The three alcohol solutions included at least one blank alcohol solution and one sample solution of the same alcohol concentration. The configuration could be either one blank alcohol solution and two sample solutions, or two blank alcohol solutions and one sample solution, at the discretion of the participants. Additionally, to reset the panelists' senses before consumption, a 520mL polyethylene terephthalate cup filled with 400mL of ultrapure water was prepared. Each panelist was given three alcoholic solutions to drink and asked to select the alcoholic beverage with the different flavor. The correct answer rate was calculated using the following formula.

[0040] Correct answer rate (%) = (Number of panelists who answered correctly / Number of panelists who answered) × 100

[0041] For panelists who conducted a sensory evaluation of three alcoholic beverages with one blank alcohol solution and two sample solutions, the panelists who selected the blank alcohol solution were correct. Similarly, for panelists who conducted a sensory evaluation of three alcoholic beverages with two blank alcohol solutions and one sample solution, the panelists who selected the sample solution were correct.

[0042] The results are shown in the tables below. Table 1 shows the results of a sensory evaluation using an alcohol solution with an alcohol concentration of 5 vol%, Table 2 shows the results of a sensory evaluation using an alcohol solution with an alcohol concentration of 10 vol%, Table 3 shows the results of a sensory evaluation using an alcohol solution with an alcohol concentration of 15 vol%, and Table 4 shows the results of a sensory evaluation using an alcohol solution with an alcohol concentration of 20 vol%.

[0043] [Table 1] [Table 2] [Table 3] [Table 4]

[0044] As shown in the table above, alcohol solutions that satisfy the relationships of equations (1), (2), and (3) above, or the relationships of equations (1), (4), and (5) above, were able to clearly distinguish the differences in flavor.

[0045] Even when a sensory evaluation is conducted using the same method as above, with an alcohol solution having an alcohol concentration of 10 vol% and an isoamyl acetate concentration of 5 μg / L, and an alcohol solution having an alcohol concentration of 10 vol% and an isoamyl acetate concentration of 150 μg / L, the difference in flavor can be fully recognized.

[0046] Even when a sensory evaluation is conducted using the same method as above, with an alcohol solution having an alcohol concentration of 15 vol% and an isoamyl acetate concentration of 5 μg / L, and an alcohol solution having an alcohol concentration of 15 vol% and an isoamyl acetate concentration of 250 μg / L, the difference in flavor can be clearly perceived.

[0047] Even when a sensory evaluation is conducted using the same method as above, with an alcohol solution having an alcohol concentration of 20 vol% and an isoamyl acetate concentration of 24 μg / L, and an alcohol solution having an alcohol concentration of 20 vol% and an isoamyl acetate concentration of 520 μg / L, the difference in flavor can be clearly perceived.

[0048] Even when a sensory evaluation is conducted using the same method as above, with an alcohol solution having an alcohol concentration of 10 vol% and an isoamyl acetate concentration of 5 μg / L, and an alcohol solution having an alcohol concentration of 15 vol% and an isoamyl acetate concentration of 250 μg / L, the difference in flavor can be clearly perceived.

[0049] Even when a sensory evaluation is conducted using the same method as above, with an alcohol solution having an alcohol concentration of 10 vol% and an isoamyl acetate concentration of 150 μg / L, and an alcohol solution having an alcohol concentration of 15 vol% and an isoamyl acetate concentration of 5 μg / L, the difference in flavor can be clearly perceived.

[0050] Even when a sensory evaluation is conducted using the same method as above, with an alcohol solution having an alcohol concentration of 10 vol% and an isoamyl acetate concentration of 5 μg / L, and an alcohol solution having an alcohol concentration of 20 vol% and an isoamyl acetate concentration of 520 μg / L, the difference in flavor can be clearly perceived.
