FAN Guo-zhi; WEI Yi-liang (Biological and Chemical Engineering Department; Wuhan Polytechnic University; Wuhan 430023; China)
Abstract:The chitin was distilled from the shell of cherax quadricarinatus with 18% yield.The chitosan was prepared from chitin by deacetylating and the degree of deacetylation was 83%. The effect of the soaking acid, temperature and the NaOH concentration on the product quality were studied. The results show that it is possible to prepare chitosan from the sheet of cherax quadricarinatus.
Key words:cherax quadricarinatus; chitin; chitosan; preparation
