茴香油微胶囊化的喷雾干燥工艺研究

Study on the Microencapsulation for Aniseed Oil by Spray-Drying

研究了茴香油喷雾干燥微胶囊化的喷雾干燥工艺。研究表明 :选用大豆分离蛋白与多糖复合作壁材并采用气流式喷雾干燥设备 ;喷雾干燥条件应为 :进料浓度 3 0 %、进风温度 195℃、出风温度 10 0± 5℃。研究结果进一步表明 :如果壁材材料改变 。

The spray drying technology conditions for the aniseed oil microencapsulation was studied.The results showed that when soybean protein isolate and polysaccharides were used as wall materials and air flow type spray drying equipment was engaged,the optimal operation condition was:slurry concentration for inlet 30%,inlet air temperature 195 ℃,outlet air temperature 100±5 ℃.The optimal conditions for spray drying would vary with the wall materials.
