FIELD : nanotechnologies; medicine; food industry.SUBSTANCE : invention relates to nanotechnology, medicine and food industry. Method for producing nanocapsules of a dry extract of cordyceps is characterized by that nanocapsules are represented by kappa-carrageenan, a core of dry extract of Cordyceps, wherein the dry extract of Cordyceps is added to the suspension of kappa-carrageenan in petroleum ether in presence of 0.01 g of glycerol ester with one or two molecules of food fatty acids and one or two molecules of citric acid as a surfactant while stirring at 800 rpm, then 6 ml of 1, 2-dichloroethane is added, obtained suspension of nanocapsules is filtered and dried at room temperature, wherein weight ratio of core : shell is 1 : 1, 1 : 2 or 1 : 3.EFFECT : disclosed is a method for producing nanocapsules of dry extract of cordyceps in kappa-carrageenan.1 cl, 3 ex
