Considerable interest has emerged in developing biodegradable food packaging materials derived from polysaccharides. Phenolic compounds serve as natural bioactive substances with a range of functional properties. Various phenolic compounds have been incorporated into polysaccharide-based films and coatings for food packaging, thereby enhancing product shelf life by mitigating quality degradation due to oxidation and microbial growth. This review offers a comprehensive overview of the current state of polysaccharide-based active films and coatings enriched with phenolic compounds for preserving fruits and vegetables. The different approaches for the addition of phenols to polysaccharides-based packaging materials are discussed. The modifications in film properties resulting from incorporating polyphenols are systematically characterized. Then, the application of these composite materials as protectants and intelligent packaging in fruit and vegetables preservation is highlighted. In future, several points, such as the preservative mechanism, safety evaluation, and combination with other techniques along the whole supply chain could be considered to design polyphenol-polysaccharides packaging more in line with actual production needs.
人们对开发源自多糖的可生物降解食品包装材料产生了浓厚兴趣。酚类化合物作为具有一系列功能特性的天然生物活性物质。各种酚类化合物已被纳入用于食品包装的多糖基薄膜和涂层中，从而通过减轻因氧化和微生物生长导致的质量下降来延长产品保质期。本文综述了富含酚类化合物的多糖基活性薄膜和涂层在保鲜水果和蔬菜方面的研究现状。讨论了将酚类物质添加到多糖基包装材料中的不同方法。系统地表征了因掺入多酚而导致的薄膜性能变化。然后，重点介绍了这些复合材料在水果和蔬菜保鲜中作为保护剂和智能包装的应用。未来，在设计多酚 - 多糖包装以更符合实际生产需求时，可考虑几个方面，如保鲜机制、安全性评估以及在整个供应链中与其他技术的结合。
