FIELD: nanotechnology.
SUBSTANCE: method for obtaining nanocapsules of a dry extract of Jerusalem artichoke in a shell of pectin is described. As a nanocapsule, a low-esterified and highly esterified apple and citrus pectin is used, as a core - a dry extract of Jerusalem artichoke. Nanocapsules are prepared by mixing a mixture of pectin in toluene with 0.01 g of E472c as a surfactant, then adding a dry extract of Jerusalem artichoke into the mixture, precipitating with diethyl ether, followed by filtering out the resulting suspension and drying the nanocapsules. Mass ratio in nanocapsules core: shell is 1:3 or 5:1. The process of obtaining nanocapsules is carried out at 25°C for 15 minutes.
EFFECT: simplification and acceleration of the nanocapsules production process and increase in yield by weight.
