    摘要:

    我国每年因保鲜处理不善而造成的果蔬损失率达20%~40%。生理性衰老、病菌侵害及机械损伤等因素会引发果蔬腐烂变质。因此,根据不同果蔬产品的腐败机理,研发能减缓产品新陈代谢、创造储存保鲜微环境、延缓成熟和衰老、抑制微生物生长繁殖、延长采后寿命和货架期的绿色果蔬保鲜包装材料具有重要意义。从植物纤维、半纤维素、改性纤维素等方面梳理生物质基可降解果蔬保鲜包装材料的制备、机理及应用的研究进展,并对发展趋势进行了展望,为“禁塑令”和“双碳”社会背景下推广使用生物质基可降解果蔬保鲜包装材料提供借鉴。未来,果蔬保鲜包装材料向着低碳节能化、绿色安全化、便捷智能化的方向发展。

    Abstract:

    In China, the loss rate of fruit and vegetable caused by poor preservation treatment reaches 20%~40% every year. Several factors including physiological aging, germs infestation and mechanical damage will cause the decay and deterioration of fresh fruit and vegetables. Therefore, according to the spoilage mechanism of different fruit and vegetable products, it is of great significance to develop green fruit and vegetable preservation packaging materials that can slow down product metabolism, create storage and preservation microenvironment, delay maturation and aging, inhibit microbial growth and reproduction, and extend post-harvest life and shelf life. The recent research progress in the preparation, mechanism analysis and application of biodegradable fruit and vegetable preservation packaging materials were reviewed from the aspects of plant fiber, hemicellulose and modified cellulose. Moreover, an outlook on the development trend was prospected, providing references for promoting the usage of biomass-based functional fruit and vegetable preservation packaging materials under the background of “plastic ban” and “double carbon” society. In the future, fruit and vegetable fresh-keeping packaging materials will develop in the direction of low-carbon, energy-saving, green and safe, convenient and intelligent.
