摘要

摘要: 以阿拉伯胶和变性淀粉为壁材,采用超声辅助乳化和喷雾干燥法对番茄红素进行微胶囊包埋。通过单因素实验和均匀设计实验考察不同配方和工艺参数,采用正交实验设计优化各因素,得到包埋最优工艺为:阿拉伯胶与变性淀粉比例1∶2,固形物含量10%,芯壁比1∶1,吐温-80用量2%,在30℃,160W条件下超声乳化10min,喷雾干燥进风温度190℃,出风温度80℃,喷雾压力18MPa,微胶囊包埋效率可达85.12%,产率为60.50%;番茄红素载量为34.87mg/g,平均粒径为8.13μm,75%的粒径集中在5¹5μm间。

Abstract: Lycopene microcapsule was prepared by ultrasonic emulsification method and spray-drying using a wall system consisting of Arabic gum and modified starch.The formula and technology of microcapsule preparation was investigated by single factor and uniform design experiments, and the optimal preparation technology were optimized by orthogonal array design as following: the Arabic gum and modified starch as the wall material with its ratio at 1∶2, the solid content in the wall material 10%, the suitable proportion of core material and wall material 1∶1, the amount of tween- 80 2%, the time of ultrasonic- assisted emulsification 10min under the contitions of temperature 30℃ and ultrasonic power 160W.The optimum spray drying conditions for microencapsulation of one layer lycopene were: the inlet temperature was 190℃, and outlet temperature was 80℃, the inlet wind pressure was18MPa, and under these conditions the capsulation efficiency was 85.12% while its productivity reached 60.50%, quantity of lycopene carrying was 34.87mg /g.The average size of lycopene microcapsule was around 8.13μm, and the distribution of 75% particle size was 5¹5μm.
