摘　　要：采用喷雾干燥法制备以紫苏油为芯材,亚麻籽胶为壁材的微胶囊,并以微胶囊化效率和含油率为考察指标,考察了制备工艺。结果表明,最佳喷雾干燥工艺条件∶壁材与芯材比为2∶3(m/m),出风温度80℃,进风温度180℃,进料速度45.56mL/min,雾化器转速为24000r/min。运用此工艺条件制备的紫苏油的微胶囊化效率为92.36%,含油率可达55.45%。The microencapsulation of perilla seed oil is prepared with spray drying method using perilla seed oil as core material and flaxseed gum as wall material.The effect factors of preparing perilla seed oil microcapsule have been investigated in detail according to microencapsulation efficiency and the oil content.The results show that the optimal spray-drying processing conditions are determined as follows：the ratio of wall material and core material is 2 ∶ 3 （m/m）,the outlet temperature is 80 ℃,and the inlet temperature is 180 ℃,the liquid feeding rate is 45.56 mL/min,and the rotating speed of centrifugal atomizer is 24000 r/min.The microencapsulation efficiency is 92.36％ and the oil content is 55.45％.
