FIELD: nanotechnology.
SUBSTANCE: method of production of nanocapsules of vitamin in sodium alginate is characterized in that the shell is used as sodium alginate, and the core - as the vitamin, in a weight ratio of core:shell as 1:3. According to the method of preparing the nanocapsules the vitamin is added to a suspension of sodium alginate in benzene in the presence of the preparation E472s while stirring at 1300 rev/sec. Then hexane is added, the resulting suspension is filtered and dried at room temperature.
EFFECT: simplification and acceleration of the process of production of the nanocapsules, and increase in the yield by weight.
