壳聚糖的应用

壳聚糖属于自然界中丰富的多糖类,也是迄今为止惟一被大量利用的多糖类。它主要来源于甲壳动物的外骨骼、菌类和昆虫的细胞壁。根据壳聚糖具有良好的抗菌活性、成膜性等性质,它可作为食品中较好的抗菌剂、果蔬保鲜剂、食品添加剂和澄清剂等;根据壳聚糖及其衍生物的螯合性质,它能解决工业污水处理中金属离子严重破坏生态平衡的问题;根据壳聚糖的生物相容性和可降解性,它还能在医学上作为外科手术缝合线使用。介绍了壳聚糖在食品领域、印染废水处理及在医药领域的应用。

Application of Chitosan

Chitosan which belongs to polysaccharides is abundant in nature,and it is the only polysaccharide which has been used much until now.It is mainly derived from crustacean exoskeleton as well as cell walls of fungi and insects.Due to its strong antibacterial activity,film-forming ability and other properties,it can be used as a good antimicrobial agent in food,fruit and vegetable preservative,food additive and clarifying agent.Because of the chelating properties of chitosan and its derivatives,it can be used to avoid serious damage to ecological balance caused by metal ions in industrial wastewater treatment.Due to the biocompatibility and degradability of chitosan,it can also be used as surgical suture in medicine.The application of chitosan in the food area,printing and dyeing wastewater treatment and medicine area was also introduced.
