The microencapsulation of sea buckthorn oil was prepared with the spray drying method using sea buekthorn oil as core material and flaxseed gum as wall material. The effect factors of preparing sea buckthorn oil microcapsule had been investigated in detail according to microencapsulation efficiency and the ratio of oil content. The results showed that the optimal spray drying processing conditions were determined as follows, the air temperature at the inlet was 180℃, and at the exit was 80℃, the rotating speed of centrifugal atomizer was 24000r/min, and liquid feed rate was 40.21mL/min. The content of microencapsulation efficiency was87.12% and the ratio of oil content was 45.09%.
