摘要
以反式叶黄素晶体为芯材,辛烯基琥珀酸酯化淀粉和蔗糖为壁材,通过乳化、均质、喷雾干燥等工艺,制备叶黄素微胶囊。通过单因素试验和正交试验确定叶黄素微胶囊化最优的工艺条件为蔗糖占总壁材质量为10%、壁材质量浓度0.15g/mL、芯壁材质量比1:15、乳化剂添加量为总壁材质量的0.6%、胶体磨均质两次、进料速度400mL/h、进风温度160℃、出风温度80℃,所得产品微胶囊效率和产率分别为92.35%和90.27%,且品质良好。
Lutein microcapsules were prepared sequentially by emulsification,homogenization and spray-drying using lutein crystal as the core material and octenylsuccinate starch in combination with sucrose as the wall material in this study.The processing technology was optimized by single factor and orthogonal array design experiments.The weight percentage of sucrose occupying the compound wall material of 10%,compound wall material concentration of 0.15g/mL,core material/wall material weight ratio of 1：15,the weight ratio of emulsifier to wall material of 0.6%,homogenization number with colloid miller of 2,feeding speed of 400 mL/h,air inlet temperature of 160℃and air outlet temperature of 80℃were found optimal,and the product obtained under these conditions presented 92.35%microencapsulation efficiency,90.27%yield and good quality.
