Chitin was obtained from shrimp exoskeleton, with a yield of 27.5 %, identifying the average values for demineralization and deproteinization with a weight percentage of 97.80 ± 3.13 % and 32.18 ± 0.14 % respectively. The biopolymer obtained was characterized by infrared spectroscopy with the presence of link stretch bands –OH at 3386 cm-1, –NH at 3124 cm-1, –C = O at 1644 cm-1 in addition to the characteristic absorptions of bonds –Csp3H of the carbon chain, which match the structure of the repeating unit of the biopolymer. Chitin was obtained as a white solid in the form of sheets, insoluble in water and diluted
