摘要
以脱皮、低温压榨紫苏油为芯材,利用乳化和喷雾干燥相结合的方法制备紫苏油粉末。确定的最佳制备工艺条件为:壁材大豆分离蛋白与麦芽糖糊精的比例1∶1.2,乳化温度70℃,固形物含量25%,芯材壁材比40∶100;均质压力50 MPa,均质2次;喷雾干燥进风温度168℃,出风温度85℃。该条件下制备的紫苏油粉末微胶囊化效率达95%,表面油含量为1%左右。
Perilla seed oil powder was prepared by emulsification and spray drying from dehulled, low - temperature pressed perilla seed oil. The optimum processing conditions were as follows：soybean protein isolate and mahodextrin was in proportion of 1 ： 1.2 as the wall materials, ratio of perilla seed oil to wall materials was 40： 100, the solid content of emulsion was 25%, homogenizing pressure was 50 MPa （homogenizing two times）, temperatures of inlet and outlet of spray drying were 168℃ and 85℃ ,respectively. Under the optimum conditions,the embedding efficiency reached 95%, and the surface oil content was about 1%.
