甲壳素(Chitin)又称甲壳质,是一种含氮多糖的高分子聚合物。在纺织、造纸、卷烟、塑料、食品、化妆品、医药、农业、环境保护等诸多领域有着广泛的用途。近十多年来,国外对其应用开发研究异常活跃。国内也引起各方面的注意和重视。甲壳素的原料主要来源于甲壳纲动物,昆虫等,自然界资源非常丰富。其中单以捕捞的虾蟹壳,每年就可提供4万吨。甲壳素化学名为聚N— Chitin, also known as chitin, is a kind of nitrogen-containing polysaccharide polymer. In the textile, paper, cigarettes, plastics, food, cosmetics, medicine, agriculture, environmental protection and many other fields have a wide range of uses. In the recent ten years, the overseas research and development of its application has been unusually active. Domestic also aroused the attention of all aspects and attention. Chitin raw materials mainly from crustaceans, insects, etc., is rich in natural resources. One of the shrimp and crab shell fishing alone, can provide 40,000 tons per year.
