FIELD: nanotechnologies.
SUBSTANCE: invention relates to nanotechnology. Method for preparing nanocapsules of quercetin or dihydroquercetin in a coat of carrageenan is described. According to this method, quercetin or dihydroquercetin is added to a suspension of carrageenan in benzene in presence of 0.01 g of E472c as surfactant with stirring at 1000 rpm. Then, petroleum ether is added. Obtained suspension of nanocapsules is filtered off and dried at room temperature. Mass ratio of the core: the shell is 1:3 or 1:1.
EFFECT: method provides simple and fast process of producing nanocapsules and increases mass output.
