TECHNICAL FIELD The present invention relates to carbonated beverages containing water-soluble dietary fiber such as indigestible dextrin, and particularly to carbonated beverages substantially free of sugar (sugar-free carbonated beverages).

Foods and drinks containing various kinds of health functional substances have been developed in order to respond to the heightened awareness of health. Indigestible dextrin is known as one of health functional substances contained in such foods and drinks.
Indigestible dextrin is a water-soluble dextrin obtained from the hydrolyzate obtained by roasting starch obtained from plants such as corn and potato, followed by hydrolysis using a starch-digesting enzyme such as amylase. It is a dietary fiber and refers to an indigestible component that is difficult for humans to digest.
Indigestible dextrin has been reported to have many functionalities such as an intestinal regulation effect, an effect of suppressing an increase in postprandial blood sugar level, and an effect of lowering triglycerides and cholesterol in the blood. Therefore, foods and drinks containing indigestible dextrin have been proposed (for example, Patent Documents 1 to 3).

The present invention will be described in more detail with reference to the following examples, but the present invention is not limited to these.

[Preparation of beverage 1]
Indigestible dextrin (product name: Fibersol 2, manufactured by Matsutani Chemical Co., Ltd.) was dissolved in water at a concentration of 13 g/L, and citral and nootkatone, valencene or limonene were dissolved in water at concentrations shown in Table 1. let me Then, carbon dioxide gas was added by a post-mix method, and sealed in a colorless and transparent PET bottle (500 ml) to obtain packaged sugar-free carbonated beverages of Examples and Comparative Examples (gas volume: 3.5).

[Test Example 1]
The beverages of Examples 1 to 3 and Comparative Examples 1 to 4 obtained as described above were evaluated by five evaluation panels regarding the taste and the strength of the LED deterioration odor (resin odor, stinkbug odor). . Tasting samples were presented to the panel at 4°C. Each beverage was irradiated with an LED (5,000,000 lx·h) or a fluorescent lamp (500,000 lx·h) before being subjected to a sensory test. As a control, a carbonated drink prepared in the same manner except that the above four compounds were not contained was used.
Evaluation was performed on a 7-point scale from 1 to 7, with 4 points for deliciousness and 1 point for LED deterioration odor for a control beverage that was not irradiated with LED (deliciousness: 7 points for the most delicious one. LED degradation odor: 7 points were given for the one in which the LED degradation odor was felt most strongly).
The results are shown in Table 1 and FIGS.

From the results shown in Table 1 and FIG. 1, it can be understood that the LED deterioration odor is felt strongly due to the irradiation with the LED, and the taste of the beverage is also reduced. In the beverages of Examples containing citral and nootkatone, valencene, or limonene, the smell of LED degradation felt when drunk was suppressed.
In the case of irradiation with a fluorescent lamp, the degree of LED deterioration odor was smaller than in the case of irradiation with an LED (Fig. 2).

[Preparation of beverage 2]
Containerized sugar-free carbonated beverages of Examples and Comparative Examples were obtained in the same manner as in Preparation 1 above, except that the concentrations of citral and nootkatone, valencene or limonene were set to the values shown in Tables 2 to 4 (gas volume: 3 .5).

[Test Example 2]
As in Test Example 1, the beverages shown in Tables 2 to 4 were subjected to LED irradiation, and then evaluated by five evaluation panels regarding deliciousness and LED deterioration odor.
The results are shown in Tables 2-4 and Figures 3-5.

Regarding citral and nootkatone, valencene or limonene, even when the molar ratio was changed in the range of 10: 1 to 1: 100, as in Test Example 1, when each compound was added alone (Table 1 2.6, citral: 2.6, limonene: 4, nootkatone: 3.2, valencene: 2.6), LED deterioration odor was suppressed.
In addition, when citral and nootkatone, valencene or limonene are added in a molar ratio of 10:1 to 1:10, when each compound is added alone (as shown in Table 1, citral: 3.4, limonene: 2.8, Nootkatone: 2.8, Valencen: 3.0), the taste was also improved.
