  A method for improving the refreshing feeling and sharpness of a chu-hi or chu-hi-taste beverage has not been sufficiently studied. In particular, there is not enough means to achieve this object without impairing the original feeling of chu-hi and without greatly changing the liquid color of the beverage.

  An object of the present invention is to improve a refreshing feeling and sharpness in a packaged beverage without impairing the feeling of chu-hi and without greatly changing the liquid color of the beverage.

  In addition, when a food or drink containing oil or fat is ingested, the oil or fat remains in the oral cavity and gives an unpleasant feeling. And when the oil accumulates, discomfort increases. Therefore, it is required to wash away oils and fats brought by meals from the mouth. If you drink a beverage such as water, you can wash away the fat from your mouth to some extent, but this is not always sufficient.

  Another subject of this invention is providing the raw material which has the capability to wash away fats and oils from a mouth.

  As a result of intensive studies, the present inventors have found that a packaged beverage in which the total content of tea-derived polyphenols and the content of citric acid and / or malic acid are in a specific range is excellent in terms of refreshing feeling and sharpness. And the liquid color of the beverage was found not to be too dark.

  5 points: "Excellent" = 5 points, "Excellent" = 4 points, "Good" = 3 points, "Normal" = 2 points, "Bad" = 1 point, 3 people The average of the evaluation points was calculated. The average point is rounded off to one decimal place, and a five-point evaluation is made. Five points are “◎ +”, four points are “◎”, three points are “◯”, two points are “△”, one point is As “x”, 2 points (Δ) or more were accepted.

  The results are shown in the table below.

  As shown in these tables, good results were obtained with beverages containing a specific range of content of citric acid and a specific range of content of black tea-derived polyphenols.

  Next, it was confirmed whether the presence of citric acid had an effect on the effect. Specifically, a beverage of Sample 1-6 'was prepared with the same formulation as Sample 1-6 except that it did not contain citric acid, and the same test as above was performed. The formulation and results are shown below. As is clear from the test results, good results were obtained without citric acid.

(Test Example 2) Comparative evaluation of citric acid and malic acid A beverage (sample 1-12) was produced with the same formulation as sample 1-6 except that citric acid was replaced with malic acid. The formulation is as shown in the table below. The results obtained by conducting the same test as in Test Example 1 for the obtained sample are shown below.

  It was found that test results such as sensory evaluation were equivalent to those of citric acid even when malic acid was used at the same concentration as citric acid.

Test Example 3 Influence of Alcohol Beverages (Sample 1-13, Sample 1-13 ′, Sample 1-14) were produced with the same formulation as Sample 1-6 except that the alcohol content was changed. The formulation is as shown in the table below. The results obtained by conducting the same tests as in Test Example 1 for the obtained samples and comparative examples are shown below.

  Good results were obtained even in the absence of alcohol. Further, when alcohol was present, the effect of the present invention was excellent regardless of the amount.

(Test Example 4) Effect of sweetener Beverages (samples 1-15 to 1-17) were produced with the same composition as sample 1-6 except that fructose-glucose liquid sugar was changed to a high-intensity sweetener. The formulation is as shown in the table below. The sweetness in terms of sucrose of Samples 1-15 to 1-17 was 2.46%. The results obtained by conducting the same test as in Test Example 1 for the obtained sample are shown below.

  It was found that good results were obtained even if the sweeteners were different.

(Test Example 5) Effect of limonene Beverages (samples 1-18 to 1-21) were produced with the same composition as sample 1-6 except that a certain amount of limonene was added. The formulation is shown in the table below. The obtained sample was tested in the same manner as in Test Example 1. The results are shown below. In the presence of a specific amount of limonene, even better effects were obtained.
