南极磷虾油微胶囊的制备

摘要

Microencapsulation of krill oil using sodium alginate and chitosan as wall materials by piercing method. Taking encapsulation efficiency as the main evaluating index, the optimum processing conditions of mi-croencapsulation of krill oil by L9(34) orthogonal test were determined as follows:sodium alginate solution con centration 1%, chitosan solution concentration 0.5%, CaCl2 solution 3%, core/wall mass ratio 1∶1,and the encapsulation efficiency was 86.45%.%以海藻酸钠与壳聚糖为壁材，采用锐孔法制备南极磷虾油微胶囊。以南极磷虾油微胶囊的包埋率作为指标，选取海藻酸钠溶液浓度、壳聚糖溶液浓度、氯化钙溶液浓度和芯壁质量比4个因素，采用四因素三水平正交试验确定最佳微胶囊化工艺。结果得到最佳工艺参数：海藻酸钠溶液浓度为1%，壳聚糖溶液浓度为0.5%，氯化钙溶液浓度为3%，芯壁质量比为1∶1，包埋率可达86.45%。
