  The present invention will be described more specifically with reference to the following examples, but the present invention is not limited thereto.

[Preparation of beverage 1]
12.5 g / L of indigestible dextrin (Product name: Fibersol 2, manufactured by Matsutani Chemical Co., Ltd.)
And dissolved in water. Next, carbon dioxide was contained by a post-mix method, and sealed in a colorless and transparent PET bottle (500 ml) to obtain a packaged sugar-free carbonated beverage of Examples and Comparative Examples.
Moreover, the gas volume of the obtained beverage was measured using a gas volume measuring device GVA-500B (Kyoto Electronics Industry Co., Ltd.). Tables 1 and 2 show the measurement results.

[Test Example 1]
With respect to the beverages of Examples 1 and 2 and Comparative Examples 1 and 2 obtained as described above, five evaluation panels evaluated the taste and the intensity of deterioration odor (resin odor, stink bug odor). Tasting samples were provided to the panel at 4 ° C. Each beverage was irradiated (5 million lx · h) with an LED or a fluorescent lamp before being subjected to the sensory test. In addition, a beverage prepared by the same method as in Comparative Example 1, which was not irradiated with the LED and the fluorescent lamp, was used as a control.
The evaluation was performed on a 7-point scale, from 1 to 7 points where the taste of the control beverage was 4 points and the deterioration odor was 1 point (delicious: 7 points were the most delicious one. Deterioration odor: the strongest deterioration odor) 7 points were felt.)
The results are shown in Tables 1 and 2 and FIGS.

  From the results shown in Tables 1 and 2, it can be understood that the deteriorated smell is strongly felt by the LED irradiation, and the taste of the beverage is also reduced. On the other hand, in the beverages of Examples 1 and 2 in which the gas volume was 4.0 or more, the deterioration odor caused by the LED irradiation felt when drinking compared to Comparative Examples 1 and 2 was suppressed, The taste was also maintained.

[Preparation of beverage 2]
Indigestible dextrin was dissolved in water at the concentrations shown in Table 4. Next, carbon dioxide was contained by a post-mix method, and sealed in a colorless and transparent PET bottle (500 ml) to obtain a packaged sugar-free carbonated beverage of Examples and Comparative Examples.
The gas volume of the obtained beverage was measured. Table 4 shows the values.

[Test Example 2]
The beverages having the indigestible dextrin concentration and gas volume shown in Table 4 were evaluated for aftertaste strength and palatability by five evaluation panels without irradiation with LED illumination.
The evaluation was performed on a 7-point scale of 1 to 7 with 4.0 points for those having an indigestible dextrin concentration of 10 g / L (aftertaste strength: 7 points with the strongest aftertaste. Sa: The best thing was 7 points.)
The results are shown in Tables 3 and 4. FIG. 3 shows the indigestible dextrin concentration (g / L, X) and gas volume (Y).

From Tables 3 and 4 and FIG. 3, the relationship between the indigestible dextrin concentration (g / L, X) and the gas volume (Y) was Y ≧ 0.1867X + 1.0667 and Y ≧ 0.28X−0.8. It can be understood that the beverage of the example that satisfies the relationship is also improved in the taste and the intensity of the aftertaste as compared with the beverage of the example that does not satisfy the relationship.
In addition, all panels judged that the thing with the aftertaste intensity | strength larger than 5 points or the thing with less than 3 points was unacceptable about a flavor point. As can be understood from FIG. 3, Y ≧ 0.1867X + 1.0667 of the above two relational expressions is derived from whether or not the intensity of the aftertaste is 5 points or less, and Y ≧ 0.28X−0.8. It was guided by whether the taste was 3 or more.
