植物精油的抗氧化活性及其在果蔬保鲜上的应用研究进展

Research Progress on Antioxidant Activity of Plant Essential Oil and Its Application in Fresh-keeping of Fruits and Vegetables

植物精油种类繁多,在植物科属中分布也十分广泛,其中含量较为丰富的有松柏科、兰科、樟科、芸香科、伞形科、唇形科及姜科等。植物精油因其具有一定抗氧化活性和广谱抑菌作用被广泛应用于果蔬的贮藏保鲜中。本文综述了植物精油的抗氧化活性成分、抗氧化作用机制,并详细分析了精油熏蒸处理、精油微胶囊、精油复合涂膜和精油保鲜纸的保鲜原理及其在果蔬贮藏保鲜中的应用,旨在为植物精油在果蔬保鲜中的研究和应用提供理论基础。

There are many kinds of essential oils,which are also widely distributed in plant families and genera.Among them,coniferae,orchidaceae,lauraceae,rutaceae,umbelliferae,labiatae and zingiberaceae are rich in essential oils contents.Essential oil is widely used in the storage and preservation of fruits and vegetables because of its antioxidant activity and broad-spectrum bacteriostasis.In this paper,the antioxidant active components and antioxidant mechanism of essential oil are summarized,and the preservation principles of fumigation of essential oil,microcapsules of essential oil,composite coating of essential oil and preservative paper of essential oil and their applications in storage and preservation of fruits and vegetables are analyzed in detail,aiming to provide theoretical basis for the research and application of essential oil in the preservation of fruits and vegetables.
