FIELD: nanotechnology.
SUBSTANCE: dry extract of topinambur is added to a suspension containing sodium alginate in butanole and drug E472c as a surface-active substance, then petroleum-ether is added, the obtained suspension of nanocapsules is filtered, washed with petroleum-ether and dried. The ratio core: shell is 1:1, 1:3, 1:5 or 5:1.
EFFECT: method ensures simplification and acceleration of the nanocapsules production process, reduction of losses during the nanocapsules production and can be used in the pharmaceutical and food industries.
