摘　　要：目的 可生物降解材料具有高效和环保的特点,可以减轻传统石油基材料过度使用带来的环境污染问题,总结可生物降解材料及其制备技术的特点为进一步促进其在果蔬包装中的应用提供参考和基础。方法 首先对现有的可生物降解材料进行分类,其次探究其制备方法,然后对近年来可生物降解材料在生鲜果蔬包装中的应用,以及对生鲜果蔬保质期和质量的影响相关的研究进行总结和分析,最后对可生物降解材料的特点和应用前景进行归纳、分析和展望。结果 可生物降解材料具有良好的性能,适当的透气性和透湿性,较高的CO_(2)/O_(2)选择透过性,可大幅度地提高果蔬的货架期。结论 可生物降解材料相较于现有的保鲜包装材料有更好的保鲜效果,高效环保,能减轻不可降解材料对环境造成的污染问题。Biodegradable materials have the characteristics of high-efficiency and environmental protection. They can solve the problem of environment pollution for overuse of petroleum-based packaging materials. The work aims to summarize the characteristics of biodegradable materials and their preparation technology to provide reference for their further application in fruit and vegetable packaging. Firstly, the existing biodegradable materials were classified. Secondly,the preparation methods of biodegradable materials were introduced. And then the application of biodegradable materials in fresh fruit and vegetable packaging and their impact on the quality of fresh fruits and vegetables in recent years were summarized and analyzed. Finally, the characteristics and application prospects of biodegradable materials were summarized, analyzed and prospected. Biodegradable materials had good properties, proper air permeability and moisture permeability, and high CO_(2)/O_(2) selective permeability, which can greatly improve the shelf life of fruits and vegetables.Compared with the existing fresh-keeping packaging materials, biodegradable materials have better fresh-keeping effect, high efficiency and environmental protection, and can reduce the environmental pollution caused by non-degradable materials.
