摘要

FIELD: biotechnology.SUBSTANCE: present invention can be used in cosmetic, medical and other industries. Method involves the following: an air bladder of a fish belonging to the sturgeon family is washed, mechanically cleaned from fatty impurities and slime, opened with an cut to wash the inner cavity of the air bladder. Muscular layer of the bladder is cut together with the outer membrane. Obtained collagen is dried at the temperatures not exceeding 25-30 °C during 72-80 hours. Dried collagen is milled into maximum 0.5 mm particles and is additionally subjected to mechanical activation in a planetary-type mill at the rotation speed of not less than 700 rpm for 10-15 minutes.EFFECT: invention prevents collagen structure destruction.1 cl
