The study is aimed to enhance the stability of poppy-seed oil by microencapsulation technology.Poppy-seed oil microcapsules were successfully prepared using arabic gum and gelatin as wall materials by complex coacervation and spray drying.The optimal formulation was determined by orthogonal test.The core/wall ratio（or different mass ratios of oil to arabic gum/gelatin）on the property of poppy-seed oil microcapsules were evaluated.The optimum preparation conditions of poppy-seed oil microcapsules were achieved when the wall material concentration was 2.0%，core/wall ratio 1∶3，pH 4.2，emulsifier concentration was 1.5%.The encapsulation efficiency was 76.9% at these conditions..The oxidation of encapsulated poppy-seed oil revealed that microcapsules can enhance the storage stability.The preparation of poppy-seed oil microcapsules by complex coacervation is simple，and the stability of poppy-seed oil is improved obviously.This methord has a good application prospect in food industry.
