转谷氨酰胺酶对乳蛋白质的改性作用

转谷氨酰胺酶是催化酰基转移反应的一种酶,可使蛋白质或多肽之间发生共价交联反应。本文介绍了转谷氨酰胺酶对牛乳蛋白质凝胶特性、乳化性、热稳定性、成膜性等特性的改性作用及其在乳品加工中的应用。

Transg lutaminase can catalyse the transfer reaction of acyl g roup,which introduce a covalent cross link between protein and peptide.In this paper,the enzymatic properties of transg lutaminase and its modification actions toward milk protein are reviewed.The enzyme can modify the milk protein functional properties of g elation,emulsification,thermostability and film -forming ability,thus can be used for milk processing .
