Estudio Fisicoquímico de Quitina y Quitosana obtenidas a partir del exoesqueleto de camarón café (Farfantepenaeus californiensis)

This work describes the obtention of chitin and chitosan from brown shrimp exoskeleton (Farfentepenaeus californiensis), which is collected Gulf California. The isolation process was carried out by a consecutive treatment that includes demineralization deproteinization. On other hand, preparation conducted through alkaline hydrolysis, product purified using membrane filters series to homogenize size macromolecular chains. According methodology, yield around 34 % 20 (dry weight), respectively. materials were characterized FTIR spectroscopy thermogravimetric analysis. Also, sample analyzed proximal test, viscometric-average molecular weight, deacetylation degree. products exhibited chemical structure physicochemical properties comparable biopolymers isolated similar sources reported in literature. Chitosan found have degree acetylation 15.87 (by 1H-NMR analysis) Mv=170 kDa. results suggest chitinous waste Sea Cortes coast can be considered promising source for used several applications region.
