FIELD: nanotechnologies.
SUBSTANCE: invention relates to nanotechnology, in particular to a method of producing nanocapsules, and describes a method of producing nanocapsules of a dry extract of propolis in a kappa-carrageenan shell. Method is characterized by that a dry extract of propolis is added to a suspension of kappa-carrageenan in ethanol in presence of 0.01 g of a glycerol ester with one or two molecules of edible fatty acids and one or two molecules of citric acid as a surfactant while mixing 800 vol/min, Then, coolant-112 is added, obtained suspension of nanocapsules is filtered and dried at room temperature, wherein weight ratio of core to shell is 1:1, 1:2 or 1:3.
EFFECT: method provides a simplification and acceleration of the process of producing nanocapsules, a reduction in losses in the preparation of nanocapsules and can be used in the pharmaceutical and food industries.
