Chitosan [b-(1,4)-2-amino-2-deoxy-D-glucopyranose], which is
mainly made from crustacean shells, is the second most abundant
natural polymer in nature after cellulose (Shahidi, Arachchi, & Jeon,
1999). It has been widely used as a natural food additive in the
food industry due to its non-toxic nature, biocompatibility, antibacterial
and film-forming properties (Majeti & Ravi, 2000). Function
of chitosan differs from its molecular weight and degree of
deacetylation.
