FIELD: nanotechnology.
SUBSTANCE: for shells of nanocapsules sodium alginate is used, and the rosemary powder is slowly added to a suspension of sodium alginate in petroleum ether in the presence of 0.01 g E472c as a surfactant, and then stirred at 1000 r/min and the ethyl acetate is poured, the resulting suspension is filtered and dried at room temperature, wherein the weight ratio of core: shell in nanocapsules is 1:1 or 1:3.
EFFECT: simplification and acceleration of the process of producing the nanocapsules of rosemary, as well as increase their yield by weight.
