| 摘 要： | 以肌动球蛋白的盐溶性、肌原纤维蛋白ATPase活性以及肌原纤维蛋白的巯基含量为指标,研究了鳙肌原纤维蛋白在-10℃,-20℃,-30℃和-40℃下冻藏时的变性情况。结果表明,在不同温度下冻藏时,鳙肌动球蛋白的盐溶性、肌原纤维蛋白的ATPase活性以及巯基含量随着冻藏时间的延长,均呈下降趋势。但是,鳙蛋白质的变性速度在不同冻藏温度下的差异是极其显著的(P<0.01)。冻藏温度越低,变性越缓慢。

| Abstract: | The denaturation of myof ibrillar protein of bighead carp ( Aristichthys nobilis) during frozen storage at
different temperatures ( - 10 e , - 20 e , - 30 e and - 40 e ) was studied by measuring the solubility of
actomyosin, ATPase activities and - SH content of myofibrillar protein. The results indicated that the solubility
of actomyosin, ATPase activities and-SH content of myofibrillar protein decreased as frozen storage progressed.
The temperature of frozen storage can significantly inf luence the rate of denaturation of myofibrillar protein ( P<
0. 01) . The lower the frozen storage temperature, the slower the rate of denaturation of protein is. |

| Keywords: | Aristichthys nobilis frozen storage myofibrillar protein denaturation |
