ABSTRACT
Chitosan is a natural polymer obtained from deacetylated chitin (Figure 33.1). It has been considered as a potential biomaterial for biomedical and pharmaceutical applications (Anitha et al., 2014) and also for food industry (Qin et al., 2012). Chitin is an important polysaccharide obtained from the exoskeleton of crustaceans such as insects, crab and fungi (Dash et al., 2011). It is a biodegradable aminopolysaccharide (Ravi and Baskaran, 2015), non-toxic and biocompatible (Mad Jin et al., 2015). Its interest as biomaterial relies on its antibacterial (Lu et al., 2014), antifungal (Qiu et al., 2014), immunity (Ma et al., 2015) and anti-tumor (Ma et al., 2015) activities.
