摘　　要：为优化以麦芽糊精为壁材制备中链甘油三酯微胶囊的工艺条件,在单因素试验的基础上,选取芯材与壁材质量比、乳化剂用量、乳状液固形物质量分数为自变量,微胶囊化效率为响应值,根据Box-Benhnken中心组合试验设计原理采用三因素三水平的响应面试验,依据回归分析确定最佳制备条件。结果表明,中链甘油三酯微胶囊最佳制备条件为:芯材与壁材质量比3.56:6.44,乳化剂用量3.59%,乳状液固形物质量分数27.6%。在此条件下微胶囊化效率预测值为96.58%,验证值为96.53%。Response surface methodology （RSM） was used to optimize the preparation conditions of medium - chain triglycerides （MCT） microcapsules. Base on single factor tests, a series of Box - Benhnken design experiments were used to obtain a mathematical regression model for encapsulation efficiency as response of three variables. The results indicated that the optimum preparation conditions were as follows： mass ratio of core material to wall material 3.56 ： 6.44, emulsifier dosage 3.59%, and the solid mass fraction of emulsion 27.6%. Under the optimum conditions, the predicted encapsulation efficiency was 96. 58% and the verified value was 96.53%.
