FIELD: chemistry; biochemistry.
SUBSTANCE: invention relates to biotechnology and can be used in various industries. The method involves the following. Initial material, e.g. cartilaginous tissue of fish, bird, shellfish or mammals is ground up. The ground initial material immersed in a 0.0025-0.05 n solution of an alkali metal salt. The obtained extract is centrifuged to separate the solid and oil phase. The obtained liquid phase is centrifuged to obtain a filtrate. The obtained filtrate is washed with distilled water which is 6 times more than the volume of the filtrate with subsequent separation and concentration of the obtained end product.
EFFECT: invention enables production of proteoglycan in unaltered undecomposed form in a short period of time.
