目的 为多糖类可食性膜应用于鲜切果蔬保鲜包装提供理论依据。方法 综述国内外常见的几种多糖类可食性膜的特点及其在鲜切果蔬保鲜中的应用，并对其未来发展方向进行展望。结果 多糖类可食性膜具有良好的成膜性，涂膜于鲜切果蔬，降低了果蔬的呼吸及生理生化速率，减少了水分的损失，延缓了乙烯的生成，抑制了褐变的发生，是一种有效的鲜切果蔬保鲜方法。结论 多糖类可食性膜应用于鲜切果蔬的保鲜包装，对鲜切果蔬的外观、风味、质地和营养品质有一定的良好影响。目前多糖类可食性膜涂膜包装仍存在一些问题，并对问题的解决进行了展望。

The work aims to provide the theoretical basis for the application of polysaccharide edible film in the fresh-keeping package of the fresh-cut fruits and vegetables. The characteristics of several common polysaccharide edible filmsat home and abroad and their application in the preservation of the fresh-cut fruits and vegetables were reviewed, and the future development direction was discussed. The polysaccharide edible film had a good film forming ability. The fresh-cut fruits and vegetables wrapped with such film reduced the respiration and physiological and biochemical rate of the fruits and vegetables, reduced the water loss, delayed the production of ethylene and inhibitedthe browning. Such film was used as a method to effectively preserve the fresh-cut fruits and vegetables. The polysaccharide edible film applied in the fresh-keeping package of the fresh-cut fruits and vegetables has some good effects on the appearance, flavor, texture and nutritional quality. However, currently some problems still exist in the polysaccharide edible film package and the solutions for these problems are discussed.
