以植物甾醇酯和葛根素为芯材,阿拉伯胶和β-环状糊精为壁材,采用喷雾干燥法制备植物甾醇酯葛根素复合微胶囊。考察了乳化剂配比、乳化剂用量、固形物含量、芯壁比、壁材比对乳化液稳定性的影响,以及进风温度、出风温度、均质压力对微胶囊化效率的影响,通过单因素试验和正交试验,确定复合微胶囊的最佳工艺参数。结果显示,复合微胶囊的最佳工艺条件为:乳化剂(蔗糖酯-单甘酯)配比6∶4(g/g)、乳化剂用量0.7%(质量分数)、固形物含量20%(质量分数)、芯壁比0.25∶1(g/g)、壁材(阿拉伯胶和β-环状糊精)比5∶5(g/g)、进风温度180 ℃、出风温度75 ℃、均质压力25 MPa。在此工艺条件下复合微胶囊中植物甾醇...

Using gum arabic and β-cyclodextrin as wall materials, blend microcapsules of phytosterol esters and puerarin were prepared by a spray drying method. The influences of emulsifier composition, emulsifier dosage, solids content, core material-to-wall material ratio, and gum Arabic-to-β-cyclodextrin ratio on emulsion stability were investigated as well as the influences of inlet temperature, outlet temperature and homogenization pressure on microencapsulation efficiency. The optimum processing parameters for the preparation of composite microcapsules were determined by combined use of s...
