FIELD: nanotechnologies.
SUBSTANCE: invention relates to the field of nanotechnology, particularly to a method for the preparation of nanocapsules, and describes a method for preparing streptocide nanocapsules in a kappa-carrageenan coat. Invention is characterized in that the streptocide is added in portions to a suspension of kappa-carrageenan in ethanol containing the preparation E472c as a surfactant at a mass ratio of core:coat 1:1, or 1:3 or 5:1, the mixture is stirred, then 1,2-dichloroethane is added, the resulting nanocapsule suspension is filtered off and dried.
EFFECT: method ensures the nanocapsules producing process simplification and acceleration, reduction in losses during the nanocapsules production, and can be used in the pharmaceutical and food industries.
