摘　　要：研究双脱甲氧基姜黄素微胶囊化制备工艺。以双脱甲氧基姜黄素为芯材,以变性淀粉和蔗糖为壁材,通过乳化、均质、喷雾干燥制备双脱甲氧基姜黄素微胶囊。通过实验确定最优的工艺条件为:变性淀粉与蔗糖质量比6:1为壁材,芯壁材质量比1:20,包埋温度40℃,包埋时间2h;喷雾干燥参数为:进风温度160℃,出风温度80℃,进料速度800mL/h,雾化器转速50Hz,所得微囊包埋率≥95%,且品质良好。Bisdemethoxycurcumin microcapsules were prepared sequentially by emulsification,homogenization and spray-drying using bisdemethoxycurcumin as the core material and modified starch in combination with sucrose as the wall material in this study. Experiment results showed that the optimum conditions of microencapsulation were temperature 60℃ ,time 2h,the ration of core-material to wall-material 1：20,modified starch/ sucrose weight ratio of 6：1 ,feeding speed of temperature of 80℃. The microencapsulation yield of these conditions. 800mL/h,air inlet temperature of 160℃ and air outlet bisdemethoxycurcumin was not less than 95% under
