ABSTRACT: Chitosan is one of the most studied polysaccharides
nowadays. Because it is non-toxic, widely used in food, pharmaceutical
processes, agricultural, and presents excellent biological properties such as
biodegradation in the human body, and antibacterial. In the present study we
reported the extraction of low cost chitosans (Cs1, Cs2, Cs3 and Cs4) from shrimp shells by
extraction of chitin (Egypt: case study), then alkaline deacetylation of
chitin with strong alkaline solution at different period of time. The different
prepared chitosans (Cs1, Cs2, Cs3 and Cs4) were characterized by FTIR
spectroscopy, thermal stability, morphology, crystallography, elemental
analysis and degree of deacetylation. The data showed that the prepared
chitosan Cs2 has the most thermal stability and the highest degree of
deacetylation.
