Abstract
Shrimp chitin and chitosan with improved characteristics were isolated from black tiger shrimp waste pretreated with 0.04 M Salicylic acid for ten hours. The pretreated shrimp shells could be efficiently demineralized and deproteinized at ambient temperature using 0.680 M HCl and 0.620 M NaOH, respectively. The duration of the treatments was 8 hours, the ash and protein residues in the final chitosan were about 0.48% and 0.51% respectively; the viscosity was 4800 cps; the solubility was up to 98%. In comparison with treatment at ambient temperature (30oC) without pretreatment, the chemical consumption, the duration of the treatment, ash and protein residues was reduced to 75-20%, whereas viscosity and absence of insolubles improved by a factor of 2.5.
Keywords: Chitin, chitosan, membrane, pretreated, Salicylic acid, wound healing management.
