Chitosan is a biocompatible and non-toxic polysaccharide obtained from chitin, found in the shells of crustaceans, insects, and fungi. Due to its greater solubility and adsorption capacity, chitosan has a wider range of applications than chitin. In this study, the use of chitin from lobster shells in the synthesis of chitosan was investigated. Throughout the production process, consisting of demineralization, deproteinization, and deacetylation stages, weight-loss-based yield calculations were carried out. In the experiments conducted with +18 mesh particle size, the calculated yield based on weight loss was recorded as 66.70% in the demineralization stage, where minerals were removed, 25.29% in the deproteinization stage, where proteins and color pigments were removed, and 14.47% in the deacetylation stage, where acetyl groups in chitin were converted to amine groups. The high concentration of calcium-based compounds in lobster shells explains the significant mass loss during the demineralization stage. At the end of the entire process, the total weight-loss-based yield was calculated as 78.72%.
