植物精油在果蔬保鲜领域的应用研究及展望

Research and Prospect of the Application of Plant Essential Oil in the Field of Fruit and Vegetable Preservation

新鲜采摘的果蔬受到各种环境因素的影响,导致水分散失、组织结构损伤、微生物侵入等。传统贮藏保鲜方式太过单一,效果不太理想。综述采用植物精油熏蒸法、浸泡法、精油-气调联用、精油-羧甲基纤维素钠(sodium carboxymethyl cellulose,CMC)/壳聚糖复配法、精油改性聚苯乙烯(polystyrene,PE)膜、精油涂布纸箱、精油微胶囊、精油保鲜纸和制备可食膜等方法对新鲜果蔬的保鲜作用研究现状,展望植物精油更为有效的保鲜应用方式。

Fresh harvested fruits and vegetables were affected by various environmental factors,resulting in water loss,tissue structure damage,microorganism invasion and so on.The traditional way of storage and preservation was too single,and the effect was not ideal.This paper reviewed the current status of the study on the preservation of fresh fruits and vegetables by plant essential oil,include plant essential oil fumigation,soaking methods,essential oil combined with gas adjustment,the compound method of essential oil and sodium carboxymethyl cellulose or chitosan,modified polystyrene(PE)film of essential oil,essential oil coated cartons,essential oil microcapsules,essential oil preservative paper and edible film preparation methods.we also look forward to the more effective applications of plant essential oil.
