Chitosan Oligosaccharide

Location:Home > Products

Chitin and Chitosan had been approved beneficial for human body, and popular in medicine,  nutrition, cosmetic, 

animal nutrition, agriculture and industry areas. Chitosan Oligosaccharide could be considered as water-soluble 

chitosan oligomer which is made from depolymerizing chitosan by enzyme. And its molecular weight (≤2kDa) is 

much lower than chitosan's (≥100KDa). The low molecular weight benefits prominent water solubility and 

bioactivities which haveattracted the interest of many researchers and companies to utilize chitosan oligosaccharide 

for various applications.
