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
