Abstract: As a natural antibacterial and antioxidant agent, plant essential oils had been studied and applied in the preservation of fruits and vegetables. Due to the long-term requirement for fresh-keeping, the microcapsule technology, which could effectively control the slow release of plant essential oils, has been aroused interests of researches. This paper mainly reviewed the structure, preparation and wall materials of plant essential oil microcapsules, as well as plant essential oil microcapsules application in fresh-keeping packaging of fruits and vegetables. This review aimed at providing research directions for plant essential oil microcapsules and had great significances for expanding the application of plant essential oils.
