Chitosan is a green, low-cost natural polymer material. The bioactivity of chitosan can be enhanced by coupling with essential oil chemicals, which can broaden the range of applications. Essential oil-chitosan (EOCS), the chitosan modified by essential oil components, which has been widely used as a multi-perspective in numerous filed of food and life in recent years. Herein, the synthesis, characterization, and recent application of EOCS are reviewed. Synthetic methods include 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC)-mediated modification, free radical-induced modification, enzyme-catalyzed modification, bromide-mediated modification, and method of forming Schiff-base directly. The successful synthesis of derivatives can be demonstrated by UV, FT-IR, TLC, and NMR. EOCSs can be used as preservative coatings, packaging materials, and antibacterial agents in the food industry, as well as drug delivery and wound treatment in biomedicine. In addition, EOCSs are also used in other industries, such as environmental protection, metal corrosion inhibition, as well as plant pest control.
壳聚糖是一种绿色、低成本的天然高分子材料。壳聚糖通过与精油化学物质偶联可以增强其生物活性，从而拓宽其应用范围。近年来，经过精油成分改性的壳聚糖（EOCS）作为一种多功能物质，已广泛应用于食品和生活的多个领域。本文综述了 EOCS 的合成、表征和最新应用。合成方法包括 1-乙基-3-(3-二甲基氨基丙基)碳二亚胺（EDC）介导的修饰、自由基诱导修饰、酶催化修饰、溴介导修饰和直接形成席夫碱的方法。通过 UV、FT-IR、TLC 和 NMR 可以证明衍生物的成功合成。EOCS 可在食品工业中用作防腐剂涂层、包装材料和抗菌剂，以及在生物医学中用作药物输送和伤口处理。此外，EOCS 还应用于其他行业，如环境保护、金属腐蚀抑制以及植物病虫害防治。
