摘要:

将大豆11S 球蛋白用碱性蛋白酶酶解得到不同水解度的酶解产物,对酶解产物溶解度和微观结构进行分析,并将猪肉肌原纤维蛋白(MPI)与酶解产物按一定比例制备肌原纤维混合蛋白凝胶,研究混合蛋白的浊度、溶解度和疏水性。结果表明:酶解产物溶解度随水解度增大而递增,同时结构发生变化,不同水解度产物与肌原纤维混合蛋白的性质亦有一定的递变趋势。

关键词: 11S 酶解产物, 肌原纤维蛋白, 混合蛋白

Abstract:

A series of hydrolysates of 11S globulin were obtained through hydrolysis reaction by alcalase. The solubility and microstructure of these hydrolysates were analyzed. In addition, the turbidity, solubility and hydrophobicity of myofibrillar protein mixture generated through mixing between myofibrillar protein isolate (MPI) and hydrolysates were also investigated. Results indicated that the solubility of hydrolysates increased as the increasing of hydrolysis degree. Meanwhile, the structures of hydrolysates were also changed due to different hydrolysis degrees.

Key words: 11S globulin hydrolysates, MPI, myofibrillar protein mixture
