Spray drying was used to produce microencapsulated Wilson's dogwood (Swida wilsoniana) oil. The influences of the emulsifier and wall materials on the encapsulation were studied in order to produce high quality encapsulated S. wilsoniana oil. The emulsions were prepared by using lecithin (L) and Tween 80 (T) with different hydrophilic-lipophilic balance. Results indicated that the stable emulsion was obtained using T and L as the compound emulsifier at a ratio of 4/6 (w/w). By virtue of the compound emulsifier (T/L 4/6), the microencapsulation efficiency (MEE) reached 91%, and the oil loading up to 35% was achieved. We also examined the influence of the wall materials on the microencapsulation of S. wilsoniana oil. All the three wall materials exhibited high MEE (> 85%), and the highest MEE (95.20%) was obtained with sodium caseinate/lactose. All the S. wilsoniana oil encapsulated with the three wall materials exhibited nearly spherical microcapsules without pores or cracks, thus protecting the oil from oxygen.
