FIELD: nanotechnology.SUBSTANCE: invention relates to a method of producing nanocapsules of green tea extract. Said method is characterised by adding green tea extract to a sodium alginate suspension in butanol in presence of glycerol ester with one or two molecules of edible fatty acids and one or two molecules of citric acid while mixing at 1,300 rpm, further, flushing ethyl acetate, obtained suspension of nanocapsules is filtered and dried at room temperature, wherein weight ratio of core: cladding of nanocapsules is 1:3, 1:1 or 1:5.EFFECT: invention simplifies and speeds up process of producing nanocapsules of green tea extract and increases mass output.1 cl, 1 dwg, 4 ex |
