The preparation of chitosan-Ag nanocomposite for food packaging
Authors
Abstract:
The present study was carried out to investigate the preparation of chitosan-Ag nanocomposite filmfor food packaging. Since chitosan is a suitable alternative to produce packaging films due to favorablefactors such as biodegradability and abundance in the world, therefore in this study, it was preparedchitosan-Ag nanocomposite with antibacterial properties for food packaging by combining chitosan andAg nanoparticles. The produced nanocomposite was characterized by XRD and FESEM. Antibacterialactivity of the produced film was studied at different concentrations of silver nitrate against Escherichiacoli and Staphylococcus aureus. The results showed high antibacterial activity in chitosan-Ag chitosan. Itwas also found that with an increase in the concentration of Ag nanoparticles in the nanocomposite to0.03, the ant antibacterial effects increased and then remained constant.
