摘要
通过碱溶酸沉法提取了南极磷虾蛋白质,研究了谷氨酰胺转氨酶的应用对蛋白质得率的影响。结果表明:碱溶酸沉法能够较好地回收南极磷虾蛋白质;在酸沉过程中,合理添加谷氨酰胺转氨酶能够提高蛋白质得率约5%。
Alkaline solubilization and acid precipitation method was employed to extract proteins from whole Antarctic krill（Euphausia superba）,and effect of transglutaminase on protein recovery yield was researched.Results indicated that the alkaline solubilization and acid precipitation method was good at recovering protein from whole Antarctic krill,and protein recovery yield was increased by approximate 5%,when transglutaminase was correctly applied during acid-induced protein precipitation.
