摘要
以β-环糊精为壁材,阿拉伯胶为辅材,对克氏原螯虾壳虾青素进行微胶囊化包埋。通过单因素试验探讨壁材种类、壁材添加量、芯材添加量、搅拌时间、搅拌温度等因素对虾青素微胶囊制备效果的影响,并通过响应面法确定微胶囊制备工艺最佳条件为:80%β-环糊精+20%阿拉伯胶添加量0.19 g/m L、芯材添加量2.68%、搅拌时间50 min、搅拌温度40.9℃,在此条件下虾青素包埋率达到92.89%。
Procam barus clarkia shell astaxanthin microcapsules were prepared usingβ-cyclodextrin and arabic gum as wall material.The effects of difference of wall materials , concentration of wall material and astaxanthin , temperature and time of magnetic stirring on the microencapsulation efficiency of astaxanthin were discussed by the single factor experiments. The optimum microencapsulation conditions were concluded by Box-Behnken center-united experiment design and response surface methodology as follows:80%β-cyclodextrin+20%arabic gum 0.19 g/mL, 2.68%astaxanthin,time of magnetic stirring 50 min, temperature of magnetic stirring 40.9℃. Under the optimized conditions, the microencapsulation efficiency was 92.89%.
