摘要
以姜为原料,经乙醇直接浸泡和索氏提取法获得的姜油树脂为心材,以β-环糊精和阿拉伯胶为壁材,经乳化、均质、喷雾干燥,制取姜油树脂微胶囊,并对其主要技术参数进行了测定。通过正交试验分析,以姜油树脂的包埋率为指标,确定了心壁材比、包接温度、搅拌时间、阿拉伯胶和β-环糊精比四个因素的最佳值,得出了姜油树脂微胶囊化的最佳工艺条件。
Microencapsulation of oleoresin ginger, which was extracted as core material from ginger with ethanol, was investigated. The β-cyclodextrin was selected as wall-material, and the ginger oil-resin extracted was microencapsulated through emulsion, homogenization and spray-drying. By way of the orthogonal experiment, the optimum technology conditions were： core-material： wallmaterial（mol/mol） of 1： 1.5, stirring time of 30min, stirring temperature of 30~C and arabic gum： β-cyclodextrin（w/w） of 3%.
