Development of nanocomposite chitosan films with antimicrobial activity from agave bagasse and shrimp shells

In this study, the nanocomposite chitosan films with antimicrobial activity from agave bagasse and shrimp shells were developed. Chitosan was successfully extracted from shrimp shells waste and cellulose nanofibers were obtained from bagasse agave. To improve the antimicrobial activity, different...

Chitosan was successfully extracted from shrimp shells waste and cellulose nanofibers were obtained from bagasse agave. To improve the antimicrobial activity, different silver nanoparticle concentrations (2.5, 5, and 10% v/v) were added in the formulation. The films were prepared using the solvent casting technique and the film samples were characterized by Fourier transform infrared spectroscopy, thermogravimetric analysis, and scanning electron microscopy. The functional properties were also evaluated, including transparency, antibacterial activity (against Escherichia coli), water-solubility, swelling, and mechanical properties. The moisture content and water solubility decreased when the silver nanoparticles and nanofiber were added to the films. An increase in strength and modulus was determined when the nanofibers were added to the film. and with the addition of silver nanoparticles a decrease of the mechanical properties proportional to the nanoparticle content was observed. Therefore, there was an increase in the mechanical properties of chitin films with the incorporation of nanofibers and the addition of 2.5% and 5% of silver nanoparticles. Chitosan/nanofiber-based films displayed a total antibacterial activity against E.coli compared to chitosan-based films, with a synergistic effect between chitosan and cellulose nanofibers. This work highlights the potential of chitosan films reinforced with nanofibers and silver nanoparticles to act as green alternative for food preservation and packaging. En este estudio se utilizaron películas nanocompuestas de quitosano con actividad antimicrobiana a partir de bagazo de agave y cáscaras de camarón. fueron desarrollados. El quitosano se extrajo con éxito de los desechos de los caparazones de camarón y se utilizaron nanofibras de celulosa. obtenido del bagazo de agave. Para mejorar la actividad antimicrobiana, se utilizan diferentes concentraciones de nanopartículas de plata. (2,5, 5 y 10 % v/v) a la formulación. Las películas se prepararon utilizando la técnica de fundición con solvente. y las muestras de película se caracterizaron mediante espectroscopía infrarroja por transformada de Fourier, termogravimetría análisis y microscopía electrónica de barrido. También se evaluaron las propiedades funcionales, incluida la transparencia, actividad antibacteriana (contra Escherichia coli), solubilidad en agua, hinchamiento y propiedades mecánicas. El contenido de humedad y la solubilidad en agua disminuyeron cuando se agregaron nanopartículas de plata y nanofibras. Las películas. Se determinó un aumento en la resistencia y el módulo cuando se agregaron las nanofibras a la película. y con la adición de nanopartículas de plata una disminución de las propiedades mecánicas proporcional a la nanopartícula Se observó el contenido. Por lo tanto, hubo un aumento en las propiedades mecánicas de las películas de quitina con la incorporación de nanofibras y adición de 2,5% y 5% de nanopartículas de plata. A base de quitosano/nanofibras Las películas mostraron una actividad antibacteriana total contra E. coli en comparación con las películas a base de quitosano, con una acción sinérgica. Efecto entre quitosano y nanofibras de celulosa. Este trabajo destaca el potencial de las películas de quitosano reforzadas con nanofibras y nanopartículas de plata para actuar como alternativa verde para la conservación y envasado de alimentos.
