摘要
以辛烯基琥珀酸酯化(OSA)变性淀粉和麦芽糊精为壁材,采用喷雾干燥法对甜橙油进行微胶囊化研究。首先对壁材组成比例、壁芯比、固形物浓度等工艺参数进行研究,采用正交实验确定了最佳工艺条件,并对产品进行了扫描电镜观察和热失重分析。实验结果表明,辛烯基琥珀酸酯化淀粉和麦芽糊精的比例为3∶1,壁芯比为5∶1,固形物含量为25%,在此条件下甜橙精油的包埋率为82.1%。微胶囊为颗粒在10~20μm的球形,包埋效果良好,甜橙精油微胶囊在220℃以下质量较稳定。
In this study,octenyl succinic anhydride(OSA)modified starch and malt dextrin are used as the wall materials,the microencapsulation of sweet orange essential oil is studied by spray drying method.Firstly,the technological parameters such as composition proportions of wall materials,ratios of wall materials to core materials and content of solids are studied.The optimum technological conditions are determined by orthogonal experiment,and the product is observed by scanning electron microscope and analyzed by thermogravimetric analysis.The experimental results show that the ratio of octenyl succinic anhydride starch to malt dextrin is 3∶1,the ratio of wall materials to core materials is 5∶1,and the content of solids is 25%.Under such conditions,the embedding rate of sweet orange essential oil is 82.1%.The microcapsules are spherical in size of 10~20μm,and the encapsulation effect is good,the quality of sweet orange essential oil microcapsules is stable below 220℃.
