FIELD: collagen extract production.
SUBSTANCE: invention relates to method for producing collagen extract from the legs of broiler chickens. The method provides for the purification of raw materials, washing, grinding, hydrolysis and extraction with acetic acid solution, centrifugation. Hydrolysis is carried out with a 2.0-2.5% solution of acetic acid with exposure for 6-10 hours at 18-25°C, and the extraction of raw materials is carried out with a 1.5-1.8% solution of acetic acid at temperature 50-55°С for 45-50 minutes with constant stirring.
EFFECT: provides high yield of collagen extract from broiler chickens legs and shortens the production cycle.
