壳聚糖制备方法的比较研究

Chitosan,a deacetylated product of chitin,is a kind of natureal polysaccharide source which has shown important role in various areas.In this paper,in terms of cross test design we found the condition under which the chitosan with high deacetylation can be obtained.The effects of preparing way and material shapes on deacetylation were investigated.In addition,we found the way for lowing hydrolysis of chitosan by putting small molecules,such as methyl alcohol,alcohol and acetone into acetic acid solution.
