对以β-环糊精为壁材、稀碱法提取鱼油为芯材,利用包络结合法制备鱼油微胶囊的工艺参数进行了研究。结果表明:以产率,效率,产品的外形和粒径大小作为评价指标,得出制备鱼油微胶囊的最佳工艺条件为:m(芯材)∶m(壁材)=1∶7,搅拌时间2h,搅拌温度45℃,乳化剂吐温80的使用量0.3 g/g鱼油。按此工艺得出的鱼油微胶囊,包埋率为90.75%,包埋效率为89.34%,电子扫描显微镜观察最终的微胶囊具有典型的柱状结构。

The microencapsulating technology parameters for fish oil encapsulation was studied.β-Cyclodextrin was selected as wall material to microencapsulate fish oil extracted by dilute alkali method.The results showed that the optimum processing parameters were: the ratio of fish oil toβ-cyclodextrint 1∶ 7,stirring time 2h,mixing temperature 45℃ and 0.15g of emulsifiers Tween 80.The embedding rate,and efficiency of the fish oil microcapsule were 90.75% and 89.34%,respectively.A typical columnar structure of microcapsule was observed by scanning electron microscope.
