The extensive usage of nonbiodegradable plastic materials for food packaging is a major environmental concern. To address this, researchers focus on developing biocompatible and biodegradable food packaging from natural biopolymers, such as polysaccharides, proteins, and polyesters. These biopolymer-based packaging materials extend the shelf life of food due to their inherent antimicrobial and antioxidant properties. An important additive that enhances these beneficial effects is gallic acid (GA), a naturally occurring phenolic compound. GA exhibits potent antioxidant activity by scavenging free radicals and excellent antimicrobial activity against a wide range of bacteria by disrupting cell membranes. These gallic acid based active packaging solutions have demonstrated remarkable abilities to inhibit lipid oxidation, enzymatic browning, and microbial contamination and even retard the ripening processes in mushrooms, walnuts, strawberries, fresh-cut apples, bananas, fish, pork, and beef. This review focuses on the antioxidant, antibacterial, and food preservation capabilities of GA-incorporated biodegradable food packaging materials as an eco-friendly alternative to conventional plastic packaging.
用于食品包装的不可生物降解塑料材料的广泛使用是一个主要的环境问题。为了解决这个问题，研究人员专注于用天然生物聚合物（如多糖、蛋白质和聚酯）开发生物相容性和可生物降解的食品包装。这些基于生物聚合物的包装材料因其固有的抗菌和抗氧化特性而延长了食品的保质期。一种增强这些有益效果的重要添加剂是没食子酸（GA），一种天然存在的酚类化合物。GA通过清除自由基表现出强大的抗氧化活性，并通过破坏细胞膜对多种细菌具有优异的抗菌活性。这些基于没食子酸的活性包装解决方案已显示出显著的能力，可抑制脂质氧化、酶促褐变和微生物污染，甚至延缓蘑菇、核桃、草莓、鲜切苹果、香蕉、鱼、猪肉和牛肉的成熟过程。本综述重点关注掺入GA的可生物降解食品包装材料作为传统塑料包装的环保替代品的抗氧化、抗菌和食品保鲜能力。
