叶醇微胶囊成壳过程的研究

Study on the shell-making process of geraniol microcapsule

以壳寡糖为壁材,对叶醇进行微胶囊化制备叶醇微胶囊,测试了叶醇微胶囊的粒径和包埋率,并利用元素分析法对叶醇微胶囊进行磷元素分析,确定了叶醇微胶囊壳中三聚磷酸钠的含量,从而进一步探索了叶醇微胶囊化过程.结果表明:使用阴离子分散剂,对微胶囊的粒径和包埋率影响较大,可以明显提高叶醇的利用率,而三聚磷酸钠仅起分散作用,并没有参与形成叶醇微胶囊壳.

Using chito-oligosaccharide as wall materials, geraniol microcapsule was prepared by making geraniol microencapsulate. The particle size and embedding rate of microcapsule was measured. The phosphorus content in the microcapsule was measured using elements analysis, thus the content of sodium tripolyphosphate in geraniol microcapsule shell was ascertained and the microencapsulation process of geraniol was further discussed. The result showed that anionic dispersant had much effect on the particle size and embedding rate of microcapsule, which could obviously increase the use ratio of geraniol. However, sodium tripolyphosphate only played dispersion role, it didn＇t participate in the formation of geraniol microcapsule shell.
