摘  要：
以水溶性大豆多糖为壁材,对喷雾干燥法番茄红素的微胶囊化工艺条件进行优化。通过单因素试验和正交试验考察壁材质量浓度、芯材壁材比、乳化剂含量、喷雾干燥进风口温度、出风口温度对番茄红素微胶囊效率的影响作用,同时用扫描电子显微镜法(SEM)对产品进行了形态观察。结果表明:最优工艺为壁材质量浓度0.28g/mL、芯材壁材比1:7、乳化剂质量分数2%、喷雾干燥进风口温度160℃、出风口温度88℃,所得微胶囊效率为91.8%,此番茄红素微胶囊产品膜结构致密完整。水溶性大豆多糖为壁材喷雾干燥法对番茄红素红素进行微胶囊包埋具有可行性。

摘  要：
Lycopene microcapsulation was prepared by spray-drying method using a wall system consisting of soluble soybean polysaccharides(SSPS).The microencapsulation efficiency was optimized by single factor and orthogonal array design experiments.Factors such as wall material concentration,ratio of core and wall material,contents of emulsifier,inlet temperature and outlet temperature were thoroughly studied.Scanning electron microscope was also employed to observe the product appearance.The optimal condition was determined to be 0.28 g/mL,1:7,2%,inlet temperature at 160 ℃,and outlet temperature at 88 ℃,respectively.The microencapsulation efficiency of products obtained under these conditions was 91.8%.The structure of the microencapsulated lycopene product is compact and complete.Microencapsulating by spray-drying of lycopene using SSPS is feasible.
