甲壳质又名甲壳素、几丁质、壳多糖等,学名为聚-N-乙酰-D-葡糖胺,广泛存在于甲壳纲动物、昆虫和霉菌中,是地球上最丰富的有机质之一。在蟹、虾、龙虾、蛤等水产品加工后的甲壳废弃物中含有10～30%的甲壳质。近年来国际上十分重视甲壳质及其衍生物的开发利用,先后在日本和美国召开过两次有关甲壳质开发利用的国际学术讨论会。在医药工业中甲壳质可以生产手术缝合线、医用纤维纸及其粘合剂、抗肿瘤剂、免疫促进剂、药物载体、埋置药物的包覆材料;用于人造泪、隐形眼镜清洗液、眼药膏和生化试 Chitin, also known as chitin, chitin, chitin and other scientific name is poly-N-acetyl-D-glucosamine, widespread in crustaceans, insects and molds, is the most abundant organic matter on Earth one. In the crab, shrimp, lobster, clams and other aquatic products after the processing of crustacean waste containing 10 to 30% of the chitin. In recent years, the international community attaches great importance to the development and utilization of chitin and its derivatives. It has successively held two international symposiums on the development and utilization of chitin in Japan and the United States. In the pharmaceutical industry, chitin can produce surgical sutures, medical fiber paper and its adhesives, antineoplastic agents, immunostimulants, drug carriers, drug-embedded coating materials; for artificial tears, contact lens cleaning fluids, Eye ointment and biochemical test
