FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing nanocapsules of tannin. Said method is characterized by that 1 g of tannin is added to a suspension of 1 g low-esterified apple pectin in petroleum ether in presence of 0.01 g glycerol ester with one or two molecules of edible fatty acids and one or two molecules of citric acid while mixing at 1,000 rpm, then 6 ml of ethyl acetate is added, produced suspension of nanocapsules is filtered and dried at room temperature.
EFFECT: invention provides faster and easier process of nanoencapsulation of tannin, as well as higher weight yield.
