Abstract: Lauraceae plants are widely distributed in China, and their essential oils have many biological activities, such as bacteriostasis, antioxidant and insect repellent activities. They are ideal natural preservatives, effective antioxidants, and green insect repellent. Therefore, they have certain research significance and broad application prospects. The effects of the growth cycle, extraction organs, extraction methods, and geographical environment on the main components of essential oils from Lauraceae plants (LEO) have been reviewed. Also, the antimicrobial, antioxidant, and repellent biological activities and the corresponding mechanisms of LEO have been emphatically analyzed. In addition, the edible coating, microcapsule embedding, and nano-emulsion technologies of LEO commonly used in food packaging and preservation fields were summarized. All these aim to lay a theoretical foundation for the applications of LEO to food preservation fields.
Key words: Essential oils of Lauraceae plants, anti-microbial, antioxidant, mechanism, food preservation applications
