Abstract: Oil bodies are the important oil storage organelles in plant seeds， particularly in oil plant seeds. Oil bodies have strong physical and chemical stability and are easily separated by centrifugation. Studies showed that oil bodies have a spherical or ellipsoid shape and are composed of outer phospholipid, integral proteins and inner liquid matrix (mostly triacylglycerol). To date，three types of integral proteins have been found in plants and are mainly localized on the surface of oil bodies. In view of the unique structures of oil bodies and integral proteins，both of them have been widely applied in the field of biotechnology. This review summarized advantages and strategies of using oil bodies in expression and purification of recombinant proteins，as well as its applications in the fields of production of pharmaceutical protein，preparation of immobilized enzymes，affinity capture of antibodies and pharmaceutical enzymes，production of nutraceuticals，enhancement of plant resistance against pathogen. The development and applications of artificial oil bodies and oil-body-emulsifying-agents were also discussed.
