摘要
以阿拉伯胶和明胶为壁材的凝聚法生产茶油微胶囊的工艺过程及条件如下 :5 %阿拉伯胶和 5 %明胶与一定量油茶籽油在 6 0℃下乳化 1min,在 p H4.4下凝聚 0 .5 h,10℃下固化 1h,经离心和真空干燥即可 .该法制备的微胶囊 ,有较高的含油率和包埋率 .其粒径与凝聚时的搅拌速度密切相关 ,但其水溶性较差 .
The polymeric micro-encapsulation of oil-tea camellia seed oil(OCSO) by using gelatin and gum Arabic as wall material was prepared as the following technical flow shows: emulsifying 5% of gelatin, 5% of gum Arabic and some OCSO at 60℃ for 1 min; condensed at pH 4.0～4.5 for 0.5 h; solidified at 10℃ for 1h; centrifugalized and dried in a vacuum drying box. This microcapsule has high oil retention and oil content, but the solubility in water was low. The diameter of microcapsule is closely related to the stirring speed during condensation.
