摘要
采用两种辛烯基琥珀酸酯化淀粉HI-CAP100和N-LOK为壁材,薄荷油为芯材,通过喷雾干燥法制备微胶囊化薄荷油,研究了不同壁材和不同薄荷油载量对微胶囊化产品的产率、效率和保留率的影响。通过正交试验优化了微胶囊化工艺条件,结果表明,以HI-CAP100为壁材、薄荷油载量为质量分数40%的微胶囊化薄荷油产品的最佳工艺条件为:固形物质量分数45%,均质压力35 MPa、喷雾干燥进风温度195℃。采用差示扫描量热分析法测定HI-CAP100为壁材的微胶囊化薄荷油产品的玻璃化转变温度为53℃,因此以辛烯基琥珀酸酯化淀粉为壁材制备的微胶囊化薄荷油产品在室温下具有良好的贮存稳定性。
Two kinds of starch octenylsuccinates were used as wall material to prepare the microencapsulated mint oil by spray drying. The effects of different starch and mint oil loading capacity on yield and encapsulation efficiency were studied. The optimal parameters by orthogonal experiments were obtained as follows： solids content 45 %, homogenizing pressure 35 MPa and dryer inlet temperature 195 ℃. Furthermore, the glass transition temperature of microencapsulated mint oil measured by DSC was 53 ℃, which indicated that the microencapsulated mint oil with starch octenylsuccinate as wall material displayed good storage stability at room temperature.
