Abstract

Способ получения нанокапсул танина, отличающийся тем, что в качестве оболочки нанокапсул используется каррагинан при их получении физико-химическим методом осаждения нерастворителем с использованием петролейного эфира в качестве осадителя.A method for producing tannin nanocapsules, characterized in that carrageenan is used as a shell of nanocapsules by their physicochemical precipitation with a non-solvent using petroleum ether as a precipitant.
