Prefa 80% and
low degree of polymerization, since low
molecular weight chitosan (LMWC) and
chitooligomers (COS) are responsible for
the chitosan biological activity.[3] Muzzarelli
et al.[4] demonstrated that chitosan with an
average molecular weight in the range of
1,000–10,000 Da is very interesting for a
number of medical and biotechnological
applications. Moreover, the low molecular
weight chitosan and chitosan oligomers
possess a high solubility in water. Thus the
development of efficient processes for
reducing the molecular size of chitosan,
without altering its chemical structure, are of
great interest. Like other polysaccharides,
