摘要
采用喷雾干燥法对富含亚麻酸枳椇籽油进行微胶囊化研究?峁砻鳎罴盐⒔耗以吓浞阶榉郑海?明胶:Mβ-环糊精1:6,M壁材:M水15:85,M芯材:M壁材1:3.5、复合剂加入量10%;最佳微胶囊化加工参数为:超声乳化10min、均质压力30MPa、进口温度160℃、出口温度80℃。所得微胶囊的包埋率为88.89%,微胶囊化效率为90.83%。经优化配比和工艺制成的枳椇籽油的微胶囊产品颗罭蛐危笮≡冢浮保唉蹋?之间,颗粒表面平整光滑、层次清晰,大小分布均匀,包埋效果好。
Spray-drying was employed for microencapsulation of Hovenia dulcis Thunb. seed oil in this study. The results showed that the best material compositions for the microencapsulation are as follows： mass ratio of gelatin to β-cyclodextrin 1： 6, wall material to water 15：85 and core material to wall material 1：3.5 as well as complex additive amount 10%. The optimum processing parameters for the microencapsulation are as follows： ultrasonic emulsification time 10 min, homogeneous pressure 30 MPa, outlet temperature 160℃ and inlet temperature 80℃. Under the optimal conditions, the embedding rate is 88.89%, and microencapsulation efficiency is 90.83%. The microcapsule particles ofHovenia dulcis Thunb. seed oil are spherical, smooth, evenly distributed and orderly arranged, with sizes between 8μm and 10μm.
