FIELD: nanotechnology.
SUBSTANCE: invention relates to nanotechnology, medicine and food industry. Method of producing guarana dry extract nanocapsules is characterized by that guarana dry extract is added to a suspension of sodium alginate in methanol 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 a surfactant while stirring 900 rpm, then 6 ml of cyclohexane 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.
