响应面法优化大鲵油微胶囊制备工艺

Optimization of preparation process of giant salamander oil microcapsule by response surface methodology

为了提高大鲵油的稳定性,采用喷雾干燥法制备大鲵油微胶囊。对壁材进行选择后,以包埋率为指标,研究壁材配比、壁芯材质量比、壁材添加量和乳化剂添加量对大鲵油微胶囊化的影响。通过单因素实验,利用响应面软件Box-Behnken设计模型确定大鲵油微胶囊化的最佳工艺条件。结果表明:大鲵油微胶囊化的最佳工艺条件为壁材配比(β-环状糊精与阿拉伯胶质量比)3.44∶1、壁芯材质量比5.37∶1、壁材添加量6.46%、乳化剂添加量2%(以壁材质量计)。在最佳工艺条件下,大鲵油微胶囊包埋率为88.06%。

In order to improve the stability of giant salamander oil, giant salamander oil microcapsule was prepared by spray drying method. After selection of wall materials, with embedding rate as index, the effects of ratio of wall materials, mass ratio of wall material to core material, dosage of wall material and dosage of emulsifier on the microencapsulation of giant salamander oil were studied. Based on single fac- tor experiment, the optimal process conditions were determined by Box - Behnken design as follows ： ratio of wall materials 3.44： 1, mass ratio of wall material to core material 5.37 ： 1, dosage of wall material 6.46% and dosage of emulsifier 2% （based on the mass of wall material）. Under these conditions, the embedding rate of giant salamander oil microcapsule was 88.06%.
