FIELD: nanotechnology.
SUBSTANCE: invention relates to encapsulation. Described is a method for producing tannin nanocapsules. Carrageenan is used as a shell of the nanocapsules. According to the method tannin is added to carrageenan suspension in benzene in the presence of E472c, at a weight ratio of tannin and carrageenan 1:3, or 1:1 or 1:2, respectively. Then petroleum ether is mixed and added. Obtained suspension of nanocapsules is filtered, washed and dried. Process of producing nanoncapsules is performed at 25 °C for 20 minutes.
EFFECT: invention provides a simpler and faster process of producing nanocapsules, reduces losses during production thereof (high mass output).
