摘　　要：以玉米低聚肽和小麦低聚肽为壁材,维生素D_(3)油为芯材,吐温-20为乳化剂,利用喷雾干燥法成功制备了2种低聚肽包埋维生素D_(3)微胶囊,对比分析了两类微胶囊单因素条件差异原因,并利用正交试验法筛选出玉米肽微胶囊和小麦肽微胶囊的最佳制备条件均为喷雾干燥温度150℃、芯材壁材比1∶20、固形物质量浓度0.15 g/mL,包埋率分别为75.8%和73.8%。微胶囊稳定性分析表明,两类微胶囊均有较好的热稳定性、溶解性和胃环境缓释作用。With corn oligopeptide or wheat oligopeptide as wall material,vitamin D_(3)oil as core material and Tween-20 as an emulsifier,two kinds of vitamin D_(3)microcapsules embedded with oligopeptide were successfully prepared by spray drying method.The reasons for the differences in single-factor conditions between the two kinds of microcapsules were analyzed.The optimal preparation conditions of corn peptide microcapsules and wheat peptide microcapsules were selected by orthogonal test,which was that the spray drying temperature was 150℃,the ratio of core material to wall was 1∶20,the solid concentration was 0.15 g/mL,and the embedding rates were 75.8%and 73.8%,respectively.The stability analysis of microcapsules showed that the two types of microcapsules had good thermal stability,solubility,and sustained release in the stomach environment.
