Description

Beer-taste beverage with reduced flavor deterioration

The present invention relates to a beer-taste beverage in which flavor deterioration is suppressed.

Consumer demands for beer-taste beverages such as beer are diversifying. Along with this, the supply method of beer-taste beverages has also diversified.
Conventionally, beer-taste beverages are generally supplied on the premise that they are sealed in cans and bottles and can be consumed at one time. However, in recent years, supply using re-capable containers is also required. However, when it is supplied in such a container, it tends to take longer to finish drinking than in the case where it is supplied in a conventional container. Therefore, there is a possibility that flavor deterioration may occur due to oxidation or gas loss between the opening and the end of drinking. Specifically, there is a possibility that the refreshing aftertaste, sharpness, and irritation of beer-taste beverages may be impaired by oxidation and gas loss. As one means for suppressing such flavor deterioration, a beer-taste beverage containing a preservative has been studied (for example, Patent Document 1).

Japanese Patent No. 5249197

Measures for preventing flavor deterioration of beer-taste beverages include addition of antioxidants in addition to preservatives, but antioxidants may not be able to sufficiently suppress flavor deterioration due to oxidation. Furthermore, there is an increasing demand for PET bottles as re-pluggable containers. However, PET bottles are more likely to deteriorate in flavor due to more oxygen intrusion and gas loss into the container over time than when bottles are opened. There are challenges. Therefore, there is a beer-taste beverage that has an excellent flavor as a beer-taste beverage and can be prevented from deterioration due to oxidation and / or gas loss so that it can be used in a re-capable container such as a PET bottle. It has been demanded.

The present invention has been made to solve such problems. As a result of intensive studies by the present inventors, the present invention includes an acidulant and a pH within a predetermined range, and further includes a bitterness-imparting agent and a sweetener. It was found that by setting the concentration within a predetermined concentration range, it is possible to obtain a beer-taste beverage having excellent flavor as a beer-taste beverage and suppressing flavor deterioration due to oxidation and / or gas loss. .

By setting the total extract amount within the above range, a light drinking mouth can be provided. The “total extract amount” in the present specification is the amount of the non-volatile component contained in the original volume of 100 cubic centimeters when the alcohol content of the beverage is 0.005% or more, that is, the extract content in the Japanese liquor tax law, that is, when the temperature is 15 degrees. For beverages with an alcohol content of less than 0.005%, the extract value (% by weight) measured for the degassed sample according to the “Beer Analysis Method 7.2 Extract” established by the International Technical Committee of the Brewery Association (BCOJ) Say.

In the beer-taste beverage of the present invention, flavor deterioration due to oxidation and / or gas loss is suppressed. Suppression of flavor deterioration due to oxidation and / or gas loss can be evaluated by measuring a change in flavor before and after leaving a sample filled with the contents in a PET bottle container at a high temperature for a predetermined period. For example, it is possible to evaluate the degree of flavor deterioration due to oxidation and / or gas loss by filling beer-taste beverages with PET bottles and allowing them to stand at 45 ° C. for 3 days and measuring changes in flavor before and after that. The condition of 45 ° C. for 3 days corresponds to deterioration equivalent to 1 month at room temperature. The higher the temperature, the faster the deterioration due to oxidation and gas loss.

The beer-taste beverage of the present invention is suitable for containerized embodiments. Examples of containers include bottles, plastic bottles, cans (bottle cans), or barrels, but are particularly suitable for use in re-capable containers such as bottles, bottle cans and plastic bottles. When filling a re-capable container, it tends to take longer to finish drinking than when it is supplied in a conventional container. Therefore, there is a possibility that flavor deterioration may occur due to oxidation or gas loss between the opening of the bottle and the end of drinking, but the flavor deterioration due to oxidation and / or gas loss is suppressed in the beer-taste beverage of the present invention. Deterioration can be effectively suppressed.

The beer-taste beverage of Example 34 is prepared by adding each raw material to water so as to have the composition shown in Table 8 in the same manner as in Example A, adding carbon dioxide gas, and filling a plastic bottle container. In the same manner as in Example A, oxidation / gas loss treatment and evaluation were performed. Compared to Example 1, in Example 34, 250 mg / L of scented perfume (manufactured by San-Ei Gen FFI Co., Ltd.) was added as a bitterness-imparting agent instead of 10 mg / L isoα acid. The results are shown in Table 8.

From the above results, the content of the sweetener (acesulfame K), the sour agent, the pH and the content of the bitterness-imparting agent (isoalpha acid) are within the predetermined ranges, regardless of the type of the bitterness-imparting agent, It had a sufficient flavor, and there was little deterioration in flavor due to oxidation / gas loss treatment.

[Example G] Examination of effect by difference in content of sweetener The effect by difference in content of sweetener was examined.
In the same manner as in Example A, each raw material was added to water so as to have the composition shown in Table 9, carbon dioxide gas was added, and the bottles were filled into Examples 35 and 36 and Comparative Examples 5 and 6 A beer-taste beverage was prepared and subjected to oxidation / gas loss treatment and evaluation in the same manner as in Example A. The results are shown in Table 9.

From the above results, in beer-taste beverages with a fixed bitterness-imparting agent (iso-alpha acid) and pH, the content of sweetener (acesulfame K) is within a predetermined range, so that flavor deterioration is caused by oxidation and gas loss treatment. It was found that can be suppressed. Specifically, compared with Comparative Examples 5 and 6, Examples 35 and 36 had a sufficient flavor, and there was little deterioration of the flavor due to oxidation / gas loss treatment.

The present invention can provide a beer-taste beverage that has an excellent flavor as a beer-taste beverage and that suppresses flavor deterioration due to oxidation and / or gas loss.
