Chitin characteristics
WebChitin is natural, nontoxic, nonallergic, antimicrobial, and biodegradable, and it is insoluble in water. There are several reports in the literature about the extraction of nanochitin from different sources. Acid hydrolysis is a well-known procedure for extracting nanochitin from seafood wastes. WebChitin can be converted by using chemical and biological methods into prominent derivate chitosan. Numerous bacteria naturally have chitin degrading ability. Results: Chitin …

Web2009). The isolated chitin was characterized against several parameters such as: moisture content, ash content, protein content and degree of deacetylation. The characteristic values of isolated chitin were compared with standard chitin to determine whether the chitin approached or conformed to the characteristics of standard chitin. Chitin (C8H13O5N)n (/ˈkaɪtɪn/ KY-tin) is a long-chain polymer of N-acetylglucosamine, an amide derivative of glucose.
