摘　　要：研究了不同的壁材组合对复合凝聚薄荷油微胶囊形态的影响,比较了3种可食用固化剂的固化效果,通过正交实验优化了转谷氨酰胺酶的固化工艺参数。实验结果表明:当以明胶/阿拉伯胶为壁材时,能够制备球状多核结构的复合凝聚微胶囊;转谷氨酰胺酶具有很好的固化效果,正交实验得到的最佳固化工艺参数为酶浓度7.5U/g明胶、反应时间12h、温度为15℃;转谷氨酰胺酶能够替代甲醛作为复合凝聚微胶囊的固化剂。The effect of different kinds of wall material on the morphology of microcapsule by coacervation was investigated. The hardening effects of three edible agents were compared. The hardening process parameter of transglutaminase was optimized by orthogonal experiment. The results of the experiment showed that the special multinuclear microcapsules by coacervation was produced when gelatin/gum arabic were used as wall material. Transglutaminase possesses excellent hardening effects. The optimal hardening process parameters by orthogonal experiment were as follows： hardening for 12 h at 15℃ with a TG concentration of 7.5U/g gelatin. Transglutaminase can be applied as hardening agent of microcapsules by coacervation instead of formaldehyde.
