En este trabajo se extrajeron quitina y quitosano de caparazones de crustáceos, principalmente de cangrejos, langostas y mejillones, variando algunos parámetros respecto a los protocolos reportados en la literatura. El procedimiento propuesto para la extracción desde los caparazones de crustáceos involucró procesos de desmineralización, desproteinización y desacetilación a las cuales se les ha adicionado una etapa de purificación. Los polímeros obtenidos fueron caracterizados por Microscopía Óptica (MO), Difracción de Rayos X (DRX), Espectroscopía de Infrarrojo con Transformada de Fourier (FTIR) y Análisis Termo Gravimétrico (TGA). Los productos obtenidos mostraron características comparables con los biopolímeros reportados en la literatura
