| 摘 要： | 以草鱼鱼鳞为原料，在低于蛋白变性温度的条件下提取酸溶性胶原蛋白(ASC)和酶溶性胶原蛋白(PSC)，并对其理化性质进行系统测定。实验结果表明，ASC 和PSC 的热变性温度分别为30～35℃和28～35℃； PSC 在溶解性能、乳化性能和乳化稳定性方面优于ASC，而在溶液黏度、吸水性能、吸油性能、起泡性以及泡沫稳定性方面，ASC 明显好于PSC。

| Abstract: | Acid-soluble collagens (ASC) and pepsin-soluble collagens (PSC) were extracted from scale of grass carp at a temperature below their denaturation temperatures. The physico-chemical properties of ASC and PSC were analyzed systematically. The results showed that the denaturation temperatures of ASC and PSC were 30 － 35 and 28 － 35℃, respectively; the dissolubility, the emulsify capacity and the emulsifying stability of PSC all were better than those of ASC, while the latter had better solution viscosity, water absorption capacity, oil absorption capacity, foaming capacity and foam stability than the former. |
