FIELD: nanotechnologies; medicine; food industry.
SUBSTANCE: invention relates to nanotechnology, medicine and food industry. Method of producing guarana dry extract nanocapsules is characterized by that dry extract of guarana is added to a suspension of kappa-carrageenan in cyclohexane in presence of 0.01 g of glycerol ester with one or two molecules of edible fatty acids and one or two molecules of citric acid as surface-active substances while stirring at 900 rpm, then 7 ml of acetonitrile 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 guarana extract.
