Resumo
Chitosan is a polysaccharide obtained from chitin’s molecule deacetylation, which is the
main composition of certain fungi species and crustaceans and insects exoskeleton. The
amino groups present in chitosan give it important biological properties such as biodegradability
and biocompatibility, activity/immunological effects and antibacterial healing. The
deacetylation of chitin is an aggressive process, which reaction processes in 6 to 8 h under
hot concentrated alkali solution. In this work, Charybdis hellerii crab shells were fragmented
and pretreated for chitosan production and each conversion step, from in natura material
pretreatment to final chitosan,were investigated in detail. Itwas observed dose and dose rate
applied as in natura as pretreated chitin influence neither pretreatment process nor chitin
deacetylation step; at 20 kGy (from
or electron beam sources), the conversion process was
performed in 60 minutes. The obtained chitosan presented low weight and deacetylation
degree compared to standard chitosan, considering specific irradiation conditions.
