FIELD: food industry.

SUBSTANCE: method for encapsulating dihydroquercetin by coacervation using natural biopolymers has been proposed. Pork gelatin and citrus pectin are used as biopolymers. Moreover, a solution of gelatin and a solution of pectin in distilled water are initially prepared, containing gelatin and pectin in each solution in an amount of 2 wt.% to the volume of distilled water at pH=7. Each solution is stirred at a temperature of 45°C a magnetic stirrer at 500 rpm for 30 minutes. Continuing stirring, dihydroquercetin is added to the gelatin solution in an amount of 1-2 wt.% by volume of the solution, continue stirring for 20 minutes at a temperature of 40°C. Add a pectin solution to the resulting mixture and mix for 5 minutes. Then reduce the pH value of the mixture to 2-4 units using 0.5 N hydrochloric acid, lower the temperature of the mixture to 10°C in an ice bath with mechanical stirring for 15 minutes. Then the resulting mixture is kept at room temperature for 24 hours.

EFFECT: preserving the antioxidant properties of dihydroquercetin.
