With the rising demand for fresh and ready-to-eat foods, antimicrobial packaging has been developed to control or prevent microbial growth as well as maintain food quality and safety. Chitosan is an advanced biomaterial for antimicrobial packaging to meet the growing needs of safe and biodegradable packaging. The application of natural essential oils as antimicrobial agents effectively controls the growth of spoilage and pathogenic microbes. Thus, chitosan edible coatings and films incorporated with essential oils have expanded the general applications of antimicrobial packaging in food products. This review summarized the effect of essential oils on modifying the physicochemical characteristics of chitosan-based films. Notably, the antimicrobial efficacy of the developed composite films or coatings was highlighted. The advances in the preparation methods and application of chitosan films were also discussed. Broadly, this review will promote the potential applications of chitosan-essential oils composite films or coatings in antimicrobial packaging for food preservation.
随着人们对新鲜即食食品的需求不断增长，抗菌包装应运而生，以控制或预防微生物生长，同时保持食品质量和安全。壳聚糖是一种用于抗菌包装的先进生物材料，以满足对安全和可生物降解包装日益增长的需求。天然精油作为抗菌剂的应用可有效控制腐败和病原微生物的生长。因此，壳聚糖可食用涂层和薄膜中加入精油，扩大了抗菌包装在食品中的一般应用。本综述总结了精油对壳聚糖基薄膜物理化学特性的修饰作用。值得注意的是，强调了所开发的复合薄膜或涂层的抗菌功效。还讨论了壳聚糖薄膜的制备方法和应用的进展。总的来说，本综述将促进壳聚糖-精油复合薄膜或涂层在食品保鲜抗菌包装中的潜在应用。
