摘　　要：概述了近十年来壳聚糖化学改性方面取得的其它一些研究进展,主要包括酶改性、脱氧胆酸改性和树枝状高分子杂化改性等,并且对改性壳聚糖的生物降解性能进行了讨论。改性壳聚糖可广泛应用于食品、农业、医药及环保等领域。Several approaches toward the chemical modification of chitosan were demonstrated in this review, including enzymatic modification, deoxycholic-acid modification and dendrimer modification of chitosans. Biodegradation properties of modified chitosans were also discussed. These modified chitosans find intensive applications in the areas such as pharmaceutics, food, agriculture and environmental protection.
