There has been keen interest in developing biodegradable food packaging materials using polysaccharides. Plant polyphenols are natural antioxidants with many health effects. Different types of plant extracts rich in polyphenols have been formulated into polysaccharide based films and coatings for food packaging. The packaging increases the shelf life of food products by decreasing the quality loss due to oxidation and microbiological growth. The release of polyphenols from the films is modulated. Polysaccharide films incorporated with certain types of polyphenols can be used to indicate the freshness of animal based products. To formulate films with desirable mechanical and barrier properties, addition levels and types of plant extracts, plasticisers and composite polysaccharide materials used should be optimized. The potential of polysaccharide based films with added polyphenols to stop the SARS-CoV-2 transmission through food supply chain is discussed. Polysaccharide based films fortified with polyphenol extracts are multifunctional with potential for active and intelligent packaging.
人们一直热衷于开发使用多糖的可生物降解食品包装材料。植物多酚是具有多种健康功效的天然抗氧化剂。不同类型的富含多酚的植物提取物已被配制成基于多糖的薄膜和涂层，用于食品包装。包装通过减少因氧化和微生物生长导致的质量损失来延长食品的保质期。多酚从薄膜中的释放是可以调节的。添加某些类型的多酚的多糖薄膜可用于指示动物源性产品的新鲜度。为了配制具有理想机械和阻隔性能的薄膜，应优化添加的多酚、植物提取物、增塑剂和复合多糖材料的添加水平和类型。讨论了添加多酚的多糖基薄膜通过食品供应链阻止 SARS-CoV-2 传播的潜力。用多酚提取物强化的多糖基薄膜具有多功能性，具有主动和智能包装的潜力。
