摘　　要：本研究以壳聚糖、麦芽糊精和蔗糖等主要材料作为壁材通过乳化喷雾干燥法制备肉桂醛精油微胶囊。研究结果表明,壳聚糖、麦芽糊精和蔗糖等不同配比的初始液的粘度和乳化稳定性对微胶囊化效果影响较大。选择一定比例浓度的壳聚糖、麦芽糊精和蔗糖,使其混合液的总粘度在125～150mPa·s左右为宜。喷雾干燥时,壳聚糖和麦芽糊精、蔗糖进行合理配比有利于得到成囊率最高和产品质量相对较好的微胶囊,选择下列壁材浓度配比会得到较为理想的微胶囊化产品:1.0%壳聚糖、1.0%～1.5%蔗糖、1.0%～2.0%麦芽糊精。This paper studied microencapsulation of cinnarnaldehyde oil by spray-drying, selected mixtures of chitason, malt dextrin and sucrose as wall materials. The results showed that the composition of the mixture affected its viscosity and stability, and was important to production rate and quality of cinnamaldehyde oil microencapsulation. The viscosity of the mixture showed be kept at 125-150mPa·s. The optimum wall composition was 1.0% chitason, 1.0%-1.5% sucrose, 1.0%-2.0% malt dextrin.
