Resumen
Resumen. La industria camaronera y en particular la camaronicultura generan entre 180-400 toneladas anuales de biomasa que puede ser aprovechada para la generación de productos de mayor valor agregado. La extracción de quitina y su derivatización como quitosano, representan una oportunidad para aprovechar la biomasa de este tipo y generar un modelo de desarrollo bioeconómico. En el presente trabajo se reportan tres estudios donde se ha utilizado quitosano como base para el desarrollo de productos de alto valor agregado. Por ejemplo, la formulación de matrices para el encapsulamiento de agentes activos de interés biomédico, encapsulados naturales en forma de emulsiones para el sector agrícola y micropartículas biodegradables para el tratamiento de fuentes de agua contaminadas con metales pesados.
Abstract. The shrimp industry and in particular shrimp farming generate between 180-400 annual tons of biomass that can be used for the generation of products with higher added value. The extraction of chitin and its derivatization as chitosan, represent an opportunity to take advantage of biomass of this type and generate a bioeconomic development model. In this work, three studies are reported where chitosan has been used as a base for the development of high added value products. For example, the formulation of matrices for the encapsulation of active agents of biomedical interest, natural encapsulates in the form of emulsions for the agricultural sector and biodegradable microparticles for the treatment of water sources contaminated with heavy metals.
