Attend the 2nd Chitin and its derivatives 360 Industry Fortum 2015

Posted by:bozhihuili    Published:2015-01-17 15:01

The 2nd Chitin and its derivatives 360° Industry Fortum 2015 was held on Jan 15th ~ 16th 2015 in Linyi city, 

Shandong province. As leading chitosan oligosaccharide researcher and manufacturer, the professor Zhao Xia from 

Ocean University of China and the president Zhang Bin of Qingdao BZ Oligo Biotech Co., Ltd attended this fortum. 

And prof. Zhao also lectured on test methods of chitosan & its derivatives. 

Prof. Zhao Xia

Chitin (Poly-N-acetyl-Glucosamine), is one of the second most abundant polymer after cellulose found in nature, present 

in the shells of all crustaceans and insects, and in certain other organisms including many fungi, algae, and yeast. The 

degree of acetylation (DA) is generally over 90%. 

The most important derivative of chitin is chitosan. Chitosan (Poly-D-Glucosamine), obtained by deacetylation of chitin 

which is removing the acetyl groups (CH3-CO-). The degree of acetylation is generally lower than 20%.

Chitooligosaccharides (Chitosan Oligomer), are the degraded products of chitosan by enzymatic hydrolysis, whose 

degrees of polymerization (DPs) are <20 and average molecular weight less than 3900Da. Unlike chitosan, COS is 

readily soluble in water due to its shorter chain lengths and free amino groups in D-glucosamine units. The low 

viscosity and greater solubility of COS at neutral pH have attracted the interest of many researchers to utilize 

chitosan in its oligosaccharide form.
