چکیده مقاله :

The present study was carried out to investigate the preparation of chitosan-Ag nanocomposite film for food packaging. Since chitosan is a suitable alternative to produce packaging films due to favorable factors such as biodegradability and abundance in the world, therefore in this study, it was prepared chitosan-Ag nanocomposite with antibacterial properties for food packaging by combining chitosan and Ag nanoparticles. The produced nanocomposite was characterized by XRD and FESEM. Antibacterial activity of the produced film was studied at different concentrations of silver nitrate againstEscherichia coliandStaphylococcus aureus. The results showed high antibacterial activity in chitosan-Ag chitosan. It was also found that with an increase in the concentration of Ag nanoparticles in the nanocomposite to 0.03, the ant antibacterial effects increased and then remained constant.
