摘　　要：选用阿拉伯胶和麦芽糊精作壁材,研究了喷雾干燥法制备二氢杨梅素微胶囊的壁材组成及工艺条件.结果表明:最佳壁材组成为二氢杨梅素/壁材15/85,阿拉伯胶/麦芽糊精70/30;最佳喷雾干燥工艺条件为进风温度190℃,固型物20%,微胶囊的包埋效率可达95%.In this paper, the composition of wall materials and the technology of spray-drying for the microencapsulation of dihydromyritin have been studied, and arabic gum and maltedextrin have been used as wall material. The results show that the optimum microencapsulation technologies of dihydromyricetin are that the ratio of dihydromyricetin and wall materials is 15/85,the ratio of Arabic gum and mahedextrin is 70/30,the inlet air temperature is 190℃ and the solid raw content is 20%, thus the microencapsulation efficiency can reach to 95 %.
