摘要
以β-谷甾醇为芯材,明胶、阿拉伯胶为壁材,利用复凝聚法制备微胶囊,并用转谷氨酰胺酶(TG酶)进行固化。通过对微胶囊的芯材含量、包埋率和外观形态分析,得出优化的制备工艺条件为:壁材质量分数8%,芯壁比1∶2,复凝聚pH值4.2,TG酶∶明胶=0.2∶1。在此条件下制得的微胶囊外观圆整、大小均一,芯材含量为34.98%,包埋率为48.21%。
β-sitosterol microcapsules are prepared by complex coacervation with β-sitosterol as the core, the mixture of gelatin and gum acacia as the shell and curing with transglutaminase. In consideration of core content, encapsulation efficiency and morphological appearance, the preparation conditions are optimized as follows: 8% of the shell material, the core-shell ratio 1:2, pH value of 4.2 and the ratio of the gelatin to transglutaminase of 0.2 : 1. The prepared microcapsules feature regular ap- pearance and uniform size, the content of the core material is 34.98% and the embedding rate reaches 48.21%.
