TECHNICAL FIELD

The present invention relates to a pyrrole compound, an aroma composition, and a food and drink and a cosmetics containing the same.

BACKGROUND ART

Aroma and taste of food and drink having great influence on preference of consumers are considered as one of important factors that characterize the food and drink. In recent years, food and drink with various kinds of fragrance and flavor have been demanded with diversification of preference of consumers. Further, aroma is an important factor not only in food and drink, but also in the field of cosmetics. There is a growing need for products having fragrance and flavor with natural feeling with an increasing demand for high-end products.

Under such circumstances, an aroma component of food and drink and cosmetics is added as an aroma ingredient as a technique for enhancing or imparting desired flavor and fragrance.

In particular, food and drink and cosmetics to which savory roasting fragrance and flavor found in roasted food and drink are imparted are extremely highly preferred and considered as one of products which are expected to be in increasing demand for times to come.

For example, JP 2015-208286 A proposes a technique for adding roasted tea extract including various pyrazine-based compounds such as 2-methylpyrazine for the purpose of imparting natural roasting aroma to food and drink. Further, examples of a compound capable of imparting such roasting aroma include 2-ethyl-3,5-dimethylpyrazine, 2-vinyl-3,5-dimethylpyrazine, guaiacol, and the like (Yuzo Mizukami: Identification of key odorants in roasted green tea by using solvent-assisted flavor evaporation apparatus under high vacuum and application of the aroma extract dilution analysis. Tea Research Journal (2012), No. 113, 55-62).

SUMMARY OF INVENTION

However, there has been a demand for a means capable of easily obtaining savorier roasting flavor and imparting aroma excellent in natural feeling.

Thus, the present invention has been made in view of the above circumstances, and an object of the present invention is to provide a means highly effective in contributing to savory roasting flavor and capable of imparting fragrance with natural feeling.

As a result of conducting extensive studies to solve the aforementioned problems, the present inventors have found that a pyrrole analogous compound represented by the following formula (1) easily contributes to savory roasting flavor and has aroma with natural feeling, thereby completing the present invention.

Specifically, the above object can be achieved by the following means.

1. A compound represented by the following formula (1):



[wherein, R1is a linear or branched alkyl group having 1 to 3 carbon atoms or a hydroxyl group; and R2is a 1-pyrrolyl group, a 2-pyrrolyl group, or a 3-pyrrolyl group.]

2. An aroma composition including a compound represented by the following formula (1) as an active ingredient.

3. A food and drink including the compound according to 1. or the aroma composition according to 2;

4. The food and drink according to 3. being a tea beverage.

5. A cosmetics including the compound according to 1. or the aroma composition according to 2.

6. A method for imparting roasting aroma to a food and drink, including a step of adding the compound according to 1. or the aroma composition according to 2. to the food and drink.
