Description
Summary:Chitosan is widely known for its unique properties such as nontoxicity, biodegradability, antimicrobial and antifungal properties. It has been used widely in medicine, beverage purification, wastewater treatment, food, and allied industries. The most prevailing method for producing chitosan involve deproteinization, demineralization, decolorization and de-acetylation of chitin. Frequently, during the intermittent intervals of these processes (deproteinization, and demineralization), the products are washed to neutrality, dried before the next phase (discontinuous processes). In this work, we introduce a time and energy saving economic process of demineralization of the deprotenized snail shells through elimination of the drying stage. The yield, moisture content and degree of deacetylation of chitosan produced from the two processes were examined. The chitosan produced from the two processes had similar surface structure and matching FTIR bands. The higher chitosan yield of this energy saving process makes it more economic.
