FIELD: chemistry.

SUBSTANCE: invention relates to biotechnology and food industry. Disclosed is a kokumi-imparting agent which is γ-Glu-Abu. Also disclosed is a complex kokumi-imparting agent, which includes a combination of not less than 1000 ppm γ-Glu-Abu; and at least one or two amino acids or peptides selected from a group consisting of γ-Glu-X-Gly, where X is an amino acid or amino acid derivative, γ-Glu-Val-Y where Y is an amino acid or amino acid derivative, γ-Glu-Ala, γ-Glu-Gly, γ-Glu-Cys, γ-Glu-Met, γ-Glu-Thr, γ-Glu-Val, γ-Glu-Orn, Asp-Gly, Cys-Gly, Cys-Met, Glu-Cys, Gly-Cys, Leu-Asp, D-Cys, γ-Glu-Met (O), γ-Glu-γ-Glu-Val, γ-Glu-Val-NH2, γ-Glu-Val-"ол", γ-Glu-Ser, γ-Glu-Tau, γ-Glu-Cys (S-Me) (0), γ-Glu-Leu, γ-Glu-Ile, γ-Glu-t-Leu and γ-Glu-Cys (S-Me). Also disclosed is a seasoning composition which includes not less than 1000 ppmw γ-Glu-Abu. The invention also describes methods of producing a food product and a beverage, as well as intermediate products for producing said food product and beverage, which include a step of adding γ-Glu-Abu to other ingredients to obtain said end products containing more than 0.002 g/dl (20 ppm) γ-Glu-Abu. The invention also describes a food product, a beverage and intermediate products for producing said food product and beverage, obtained using said methods and containing more than 20 ppm (specifically less than 200 ppm) γ-Glu-Abu and optionally at least one edible organic acid or a salt thereof, table salt, along with a carrier acceptable for food products and/or at least one or two seasoning ingredients. The invention discloses methods of boosting taste of a food product or beverage, which include a step of adding not less than 400 ppmw γ-Glu-Abu to the food product or beverage.

EFFECT: invention enables to impart kokumi to food products and beverages.
