Abstract

Chitin and chitosan have become of great interest not only as underutilized resources, but also as new functional materials of high potential in various fields. The methods of isolating chitosan from different sources: shrimp (Panaeus monodon), crab (Scylla olivicea and Scylla serrata), locust (Schistocerca gregaria), honeybee (Apis mellifera), beelte (Calosoma rugosa) and fish (Labeo rohita) were compared. The same steps of demineralization and deproteinization were followed for the chemical extraction of chitin, but the concentration of reagents, the temperatures and reaction times were varied, which resulted in chitosans with different degrees of deacetylation.
