    Desarrollo de films poliméricos biobasados con Eugenol y Acetileugenol: Inhibición del Crecimiento Bacteriano
    (AJEA - Acta de Jornadas y/o Eventos Académicos de UTN, 2024-12-27) Boriglio, Rocío; Córdoba Boschetti, Brisa; Bresán, Luisina; Taverna, María E.; Busatto, Carlos Alberto; Garnero, Paula Carolina
    El creciente interés por alimentos frescos sin conservantes sintéticos ha impulsado el desarrollo de envases activos para mejorar su conservación. El uso de antimicrobianos naturales, como el eugenol, es una alternativa prometedora debido a sus propiedades antisépticas y antibacterianas, aunque su volatilidad y sensibilidad al oxígeno y la luz limitan su aplicación. El acetileugenol, un derivado del eugenol, también ha demostrado actividad antimicrobiana. Incorporar estos compuestos en matrices poliméricas biobasadas es una solución eficaz para crear envases activos que prolongan la vida útil de los alimentos sin recurrir a conservantes sintéticos. El objetivo de este trabajo es la síntesis del acetileugenol, y el desarrollo de films de alginato y quitosano conteniendo eugenol y acetileugenol como agentes inhibitorios de bacterias como Escherichia coli y Staphylococcus aureus. Los resultados muestran que es posible obtener films biobasados con excelentes propiedades inhibitorias del crecimiento bacteriano.

    Bio-composite Films Based on Alginate and Rice Husk Tar Microparticles Loaded with Eugenol for Active Packaging
    (2022-01-29) Taverna, María E.; Busatto, Carlos Alberto; Saires, Paula J.; Bertero, Melisa Paola; Sedran, Ulises A.; Estenoz, Diana
    This work focused on the valorization of tar derived from rice husk pyrolysis as a precursor of matrices for the encapsulation of active principles. In this regard, the development of novel films based on alginate and eugenol-loaded tar microparticles with suitable mechanical properties and antibacterial activity was studied. Tar microparticles loaded with eugenol were incorporated into sodium alginate films and the effect on the mechanical, thermal and humidity resistance properties were determined, as well as the antimicrobial activity. Films with different crosslinking degrees were also prepared using CaCl2, and the eugenol controlled release profiles were evaluated. Crosslinked films exhibited improved mechanical and humidity resistance properties, as well as a lower release rate of eugenol in water. The antimicrobial studies showed that eugenol-loaded films present a higher antimicrobial activity against Staphylococcus aureus. Alginate/eugenol-loaded tar microparticles composites showed an enhancement of antibacterial properties and suitable physical characteristics to be used in active packaging applications.
