FIELD: nanotechnology.
SUBSTANCE: method of obtaining nanocapsules of a biopag-D mixture with a diamond green is proposed. The way is that to 2.5 grams Biopag-D is added 2.5 ml of brilliant green, the resulting mixture is added to the suspension 2.5 grams or 7.5 g Apple or citrus pectin in petroleum ether and 0.05 g Preparation E472c as a surfactant, the obtained mixture is put on a magnetic stirrer and stirring is carried out, the precipitated nanocapsule suspension is filtered on a 16 grade porous Schott filter, washed with petroleum ether, dried in a desiccator over calcium chloride. A distinctive feature of the proposed method is the use as an envelope of nanocapsules of apple or citrus pectins.
EFFECT: nanocapsules manufacture process simplification and acceleration and weight yield increase.
