摘    要:转谷氨酰胺酶可以催化肌原纤维蛋白发生交联反应。随着交联程度的增加,鱼糜凝胶从弹黏体变为弹脆体,风味也随之改变。风味物质的扩散、释放与凝胶网络的交联程度密切相关,因此深入了解交联程度与食品品质的关系及风味物质在凝胶网络中的扩散行为显得尤为重要。本文总结转谷氨酰胺酶催化肌原纤维蛋白的交联机理,归纳了国内外对肌原纤维蛋白交联程郭彩霞度的测定方法与影响因素,探讨交联程度对鱼糜蛋白的凝胶特性与风味释放的影响,并对今后的研究方向提出思考与展望。

关 键 词:转谷氨酰胺酶  肌原纤维蛋白  交联程度  检测方法  鱼糜凝胶  影响因素

Abstract:Transglutaminase catalyses the cross-linking of myofibrillar proteins. Textural properties of surimi gel can
be transformed from elastico-viscous body to elastico-crisp body in response to an increase in cross-linking degree,
accompanied by an obvious change in its flavor. The flavor diffusion and release are closely related to the degree of
compactness and interactions of gel structure. So it is very meaningful to study the relationship between the cross-linking
degree and texture properties of foods, and the diffusion behavior of flavor compounds in gel networks. In this paper, the
mechanism of transglutaminase-catalyzed cross-linking of myofibrillar protein is summarized. Existing assay methods for
the cross-linking of myofibrillar protein and its influencing factors are also reviewed. The effects of cross-linking degree on
surimi gelation and flavor are discussed. Moreover, further research directions are proposed.
Keywords:transglutaminase  myofibrillar proteins  cross-linking degree  assay methods  surimi gelation  influencing factors
