Chitosan is a bio-renewable natural polymeric material. The antibacterial and antioxidant activity of chitosan can be enhanced by grafting with phenolic acids to further expand its application in food. Therefore, this paper focuses on reviewing the structure, antimicrobial and antioxidant activities and their mechanisms with phenolic acid-g-CS, evaluating its cytotoxicity, and describing its application in various food preservation. In general, different reaction mechanisms of phenolic acid-g-CS synthesis lead to different product structures. Compared to chitosan, phenolic acid-g-chitosan exhibited enhanced antibacterial and antioxidant activities. The toxicity assessment showed that phenolic acid-g-CS is not cytotoxic. Moreover, phenolic acid-g-CS has been applied to a variety of food products such as fruits, vegetables and meat with good results. Overall, this review provides a certain reference for subsequent researchers to design phenolic acid-g-CS more rationally and for the subsequent development of phenolic acid-g-CS in food preservation.
壳聚糖是一种可再生的天然高分子材料。通过与酚酸接枝，可以提高壳聚糖的抗菌和抗氧化活性，进一步拓展其在食品中的应用。因此，本文重点综述了酚酸接枝壳聚糖的结构、抗菌和抗氧化活性及其机制，评估其细胞毒性，并描述其在各种食品保鲜中的应用。总的来说，酚酸接枝壳聚糖的合成反应机制不同，导致产物结构不同。与壳聚糖相比，酚酸接枝壳聚糖表现出增强的抗菌和抗氧化活性。毒性评估表明，酚酸接枝壳聚糖没有细胞毒性。此外，酚酸接枝壳聚糖已应用于多种食品，如水果、蔬菜和肉类，效果良好。总的来说，本综述为后续研究者更合理地设计酚酸接枝壳聚糖以及酚酸接枝壳聚糖在食品保鲜中的进一步发展提供了一定的参考。
