A method for obtaining a functional additive provides for preparing grape seeds, obtaining an extract of polyphenol compounds and the further mixing thereof with a filler. The grape seeds are ground up to particle size of , then polyphenol compounds are extracted therefrom with an aqueous-alcohol solution at the simultaneous treatment with pulsed microwave field. A temperature of the medium is 47-. The polyphenol extract thus obtained is mixed with maltodextrine at a ratio of 1:(1-4), and the mixture is subjected to lyophilic drying at a temperature of 45-. |
