The chitin isolation process was carried out by a consecutive treatment that includes demineralization and deproteinization. On the other hand, the preparation of chitosan was conducted through alkaline hydrolysis, and the product was purified by using a membrane filters series to homogenize the size of the macromolecular chains. According to the methodology, the yield of chitin and chitosan was around 34 % and 20 % (dry weight), respectively. The materials were characterized by FTIR spectroscopy and thermogravimetric analysis. Also, the chitosan sample was analyzed by proximal test, viscometric-average molecular weight, and deacetylation degree. The products exhibited chemical structure and physicochemical properties comparable to biopolymers isolated from similar sources reported in the literature. Chitosan was found to have a degree of acetylation of 15.87 % (by 1H-NMR analysis) and Mv=170 kDa. The results suggest that the chitinous waste from the Sea of Cortes coast can be considered a promising source for the preparation of chitosan and used for several applications in the region. Este trabajo describe el aislamiento de quitina y optimización del proceso de desacetilación para obtener quitosana a partir del exoesqueleto de camarón café (Farfentepenaeus californiensis) recolectado del Golfo de California. La extracción se realizó a través de un proceso consecutivo de desmineralización y desproteinización. Por otro lado, la desacetilación se llevó a cabo por hidrólisis alcalina y el producto se purificó utilizando una serie de filtros de membrana para homogeneizar el tamaño de las cadenas macromoleculares. De acuerdo con la metodología seguida, se obtuvo rendimiento del 33 % y 23 % (base seca) de quitina y quitosana, respectivamente. Los materiales se caracterizaron por espectroscopía FTIR y análisis termogravimétrico. Asimismo, se evaluó el análisis proximal, peso molecular viscosimétrico y el grado de acetilación en la muestra de quitosana. Los productos obtenidos presentaron estructura química y propiedades fisicoquímicas comparables con los biopolímeros aislados por métodos similares reportados en la literatura. Se encontró que la quitosana pura tiene un grado de acetilación de 15.87 % (estimado por 1H-RMN) y . Los resultados obtenidos sugieren que los desechos quitinosos del Mar de Cortés pueden considerarse como una fuente importante para la preparación de quitosana y utilizarse para diversas aplicaciones de la región Universidad de Sonora 2022-05-31 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Original peer-reviewed articles Artículos originales evaluados por pares application/pdf text/xml https://biotecnia.unison.mx/index.php/biotecnia/article/view/1616 10.18633/biotecnia.v24i2.1616 Biotecnia; Vol. 24 No. 2 (2022): Mayo-Agosto; 28-35 Biotecnia; Vol. 24 Núm. 2 (2022): Mayo-Agosto; 28-35 1665-1456 1665-1456 eng https://biotecnia.unison.mx/index.php/biotecnia/article/view/1616/685 https://biotecnia.unison.mx/index.php/biotecnia/article/view/1616/752 Derechos de autor 2022 https://creativecommons.org/licenses/by-nc-sa/4.0 |
