Synthesis of Chitosan from Crab’s Shell Waste (Portunus pelagicus) in Mertasinga-Cirebon

Abstract: The crab shell waste contains many chitins. When it processed in several chemical processes, it can produce chitosan, which has many benefits and economic value. Chitosan is a linear polysaccharide that consists of N-acetyl glucosamine and D-glucosamine monomers. This study aims to determine the optimum condition of temperature and time of the deacetylation process from the chitin crab shell (Portunus pelagicus) to be chitosan. There are three stages of making chitosan; deproteination, demineralization, and de… Show more

“…Crab powder samples can be immersed in a 1:15 (w/v) solution of 1 M HCl to remove the mineral content. The use of an HCl solution is intended to cause minerals (inorganic compounds in the form of salts) to react with HCl to form a soluble chloride salt, resulting in a chitin precipitate, as shown in reaction Equation 2-6 [23]:…”

“…Utilization of crab in the form of whole crab products and crab meat. Blue Crab is one of the export commodities of the Indonesian fisheries sector, which is sold in the form of frozen or canned crabs [17]. Several groups of fishermen who process crab crabs and some are processing them into small crab crackers [18].…”

“…As a consequence of meat extraction from crustaceans, a great amount of shell waste is produced, which represents 40-60% of the total animal weight. As it is necessary to reuse the waste, among different strategies, chitin and chitosan extractions represent a good choice [2].…”
