摘要:

通过对鲢鱼鱼糜凝胶特性和溶解率的测定及SDS-PAGE检测研究鸡蛋清蛋白改善鱼糜凝胶特性的机理及其对微生物转谷氨酰胺酶(MTGase)诱导鱼糜凝胶形成的影响。结果表明:鸡蛋清蛋白(EA)和MTGase均能显著提高鱼糜凝胶特性。EA会降低MTGase诱导鱼糜凝胶的形成,显著降低MTGase诱导鱼糜凝胶的凝胶强度和破断强度,但不阻碍MTGase对肌球蛋白重链(MHC)的交联。

关键词: 鸡蛋清蛋白, 转谷氨酰胺酶, 鱼糜凝胶

Abstract:

The formed silver carp surimi gels with the addition of egg albumin (EA), microbial transglutaminase (MTGase) or both of them were tested for their properties and SDS-PAGE patterns in order to examine the effect of EA on the properties of MTGase-induced silver carp surimi gels. EA or MTGase could significantly improve surimi gel properties. EA inhibited the formation of MTGase-induced surimi gels, and resulted in a noticeable decrease in their gel strength and breaking force, but had no inhibitory effect on cross-linking of myosin heavy chain.

Key words: egg albumin, transglutaminase, surimi gels
