甲壳质又叫甲壳素、几丁质、壳多糖,它广泛存在于微生物、酵母、蘑菇的细胞壁中,昆虫的表皮、乌贼、贝壳等软体动物的骨骼内,尤其是虾子、螃蟹等甲壳类的甲壳富含甲壳质。每年其生物合成量约为100亿吨,产量仅次于纤维素,是地球上第二大再生资源。尽管甲壳质和植物纤维素的性质、作用有别,但由于二者的化学结构相似,故又有动物纤维素之称。 近年来国外十分重视甲壳质的开发利用,有关国际性学术会议相继召开;从20世纪80年代起,我国的研究也逐渐增多,但主要局限在化工、纺织、造纸、涂料、食品、化妆品等方面。20世纪90年
Chitin, also known as chitin, chitin, chitin, is widely present in the cell walls of microorganisms, yeast, mushrooms, the insect’s epidermis, cuttlefish, shells and other mollusks, especially shrimp, crabs and other crustaceans Chitin is rich in chitin. Its annual biosynthesis is about 10 billion tons, yield second only to cellulose, is the second largest renewable resource on Earth. Although the properties of chitin and plant cellulose, the role of different, but the chemical structure of the two are similar, so there are animal called cellulose. In recent years, foreign countries attach great importance to the development and utilization of chitin, the international academic conferences have been held; from the 1980s, China’s research has gradually increased, but mainly in the chemical, textile, papermaking, coatings, food, cosmetics and so on . 90 years of the 20th century
