鲢鱼肉冻藏期间理化特性的变化

Effect of Frozen storage on The Salt-Soluble Protein of silver Carp Muscle

本文研究了水洗和未水洗鲢鱼肉在－１０℃、－２０℃的冻藏中，盐溶性蛋白的变化规律及其变性的动力学方程。结果表明：未水洗的鲢鱼肉蛋白质比水洗的更易变性。－１０℃冻藏时盐溶性蛋白的变化速度常数明显高于－２０℃冻藏时的变化。盐溶性蛋白的下降主要发生在冻藏的前６周。

Abstract The paper studied the changes and dynamics of salt-soluble protein of wash and unwash silver carp muscle during -10℃ and -20℃ storage.The saltsoluble protein of unwash silver carp muscle decreased faster thean wash muscle.The rate constants of salt-soluble protein changes at -10℃ was more than that at -20℃.The saltsoluble protein decreased rapidly during first 6 weeks frozen storage.
