冷水可溶性多孔淀粉制备VE微胶囊的研究

Preparation of VE Microcapsules by Cold-water-soluble Microporous Starch

以冷水可溶性多孔淀粉为壁材,采用超声波法制备VE微胶囊,以包埋率为评价指标,对VE微胶囊制备工艺进行优化。结果表明,VE微胶囊制备的最佳条件为超声时间30 min,超声温度45℃,壁芯比为2.0∶1(g∶g),制得VE微胶囊包埋率为80.06%±0.23%,VE微胶囊呈淡黄色。

Cold-water-soluble porous starch was used as wall material,and VE microcapsule was prepared by ultrasonic treatment.The encapsulation efficiency was used as evaluation index to optimize the preparation process of VE microcapsule.The results showed that the best conditions for the preparation of VE microcapsules were ultrasonic time 30 min,ultrasonic temperature 45℃,and wall core ratio 2.0∶1(g∶g).The encapsulation efficiency of VE microcapsules was 80.06%±0.23%,and VE microcapsules was light yellow.
