    ABSTRACT

    Background:The present work was conceded to know the improved and comparable properties with bio-nanocomposite films. The films were prepared by using blends of Carboxy Methyl Cellulose (CMC), a cellulose derivative; pectin by wet casting was used to create the films with incorporation of silver nanoparticles that had been produced.Materials and Methods:The silver Nanoparticles (AgNP’s) were synthesized by eco-friendly method by using Psidium guajava leaf extract. Incorporation of AgNP’s into CMC and pectin films (bio-nanocomposite films) was characterized by SEM. Also its mechanical properties, WVTR activity and anti- microbial studies were carried out in the present work.Results: SEM results have shown that formation of spherical shaped nanoparticles which is Ag nanoparticles coated bio-nanocomposite films. According to the WVTR results, adding more AgNP's to films decreased their humidity and ability of water absorption. The mechanical properties of the films were improved. The films showed remarkable antibacterial activity against E. coli, Bacillus, S. aureus, and Klebsiella pneumoniae. Conclusion:These characteristics imply that AgNP's-based bio-nano composite films find use in the food industry as an active packaging material.
