Abstract: Hydrolysis products of channel catfish skin was extracted by using acetic acid method and acetic acid + papain method,and their physico-chemical properties were described.Results showed that the denaturation temperatures of acid-soluble hydrolysis products and acetic acid + papain hydrolysates were at 30~35 ℃ and 28~35 ℃ respectively.The dissolubility,emulsify capacity and emulsifying stability of products obtained by acetic+papain method were superior to that obtained by acetic acid method,but the latter produced a better water absorption capacity,oil absorption capacity,foaming capacity and foam stability than the former.

Key words: Channel catfish skin, hydrolysis products, physico-chemical properties
