摘要: 研究虾夷扇贝贝糜在不同温度冻藏过程中(-18℃和-35℃)肌动球蛋白的盐溶性、Ca2+-ATPase和Ca2+-Mg2+-ATPase活性及活性巯基与总巯基含量的变化。结果显示:-18℃条件下冻藏5个月时,贝糜蛋白已严重变性,其各指标值分别降至新鲜样品的11.28%、20.31%、30.36%、68.49%和83.67%。-35℃条件下冻藏10个月时,相应指标分别降至新鲜样品的60.01%、45.25%、48.17%、82.80%和88.71%。两种冻藏温度条件下,贝糜的各个指标均随冻藏时间的延长而呈下降趋势,且-35℃冻藏时,各指标值相对于-18℃冻藏时下降幅度较小,表明-35℃冻藏效果优于-18℃冻藏。

Abstract: The changes of biochemical properties, including the salt extractable protein content, Ca2+-ATPase activity, Ca2+-Mg2+-ATPase activity and the contents of total and active sulfhydryl groups, of scallop (Patinopecten yessoensis) mince during frozen storage (-18 or -35 ℃) were investigated. The results showed that the protein denaturation was very serious after 5 months of storage at -18 ℃. The solubility in salt solutions, Ca2+-ATPase and Ca2+-Mg2+-ATPase activity, total and sulfhydryl group contents of actomyosin decreased to 11.28%, 20.31%, 30.36%, 68.49% and 83.67% of their original values after 5 months of storage at -18 ℃ and to 60.01%, 45.25%, 48.17%, 82.80% and 88.71% after 10 months of storage at -35 ℃, respectively. Under each temperature condition, all the parameters showed a downward trend with prolonged storage period and decreased less at -35 ℃ than at -18 ℃. Therefore, -35 ℃ was more suitable for storing scallop mince than -18 ℃.
