摘　　要：壳聚糖是自然界中存量巨大的多糖类物质,在食品、医药、农业、环保等领域发挥着许多重要的作用。其脱乙酰度是评判其性能的重要指标之一,这使得在实际应用中对脱乙酰度检测方法的便利性和准确性提出较高的要求。本文综述了化学分析方法、光谱学分析方法、破坏性分析方法和电特性分析方法,探讨各种分析方法及其改进方案的优缺点,发现化学分析法和光谱分析法不仅检测效果好,应用范围也更广,电特性分析方法则具有广阔的发展前景。高脱乙酰度的壳聚糖的抗菌保鲜能力受到重视,中低脱乙酰度的壳聚糖则在医学和环保领域发挥重要作用,通过对不同脱乙酰度的壳聚糖在食品工业中抗菌、保鲜和包装等方面的应用以及环保和组织工程等领域的功能展开讨论,为壳聚糖脱乙酰度的测定及其多方面的应用提供参考依据。Chitosan are abundant polysaccharides in nature,which play many important roles in food,medicine,agriculture,environmental protection and other fields.The deacetylation degree of chitosan is also one of the most important indexes to evaluate their performance.Therefore,the convenience and accuracy of deacetylation degree detection method are highly required in application.In this paper,the chemical analysis methods,spectral analysis methods,destructive analysis methods and electrical characteristics analysis methods are summarized,and the advantages and disadvantages of various methods and their improvement schemes are discussed.It is found that chemical analysis and spectroscopy have not only good detection results,but also a wider range of applications,while electrical characteristics analysis methods have broad prospects for development.The antibacterial and fresh-keeping ability of chitosan with a high degree of deacetylation is valued,while chitosan with a low degree of deacetylation plays an important role in medicine and environmental protection.The functions of chitosan of antibacterial,preservation and packaging in the food industry and application in environmental protection and tissue engineering were introduced to provide reference for the determination of the deacetylation degree of chitosan.
