Production Film based on LDPE / Ag / TiO2 nanoparticles by SOL-GEL method and evaluation of Sander Lucioperca fish shelf life

In this study, LDPE / Ag / Tio2 nanocomposite films were manufactured by solvent-soluble sol-gel (1% , 3% and 5% nano silver and 0.5%, 1.5% and 2.5% titanium dioxide) and then the prohibition of the growth of productive films investigated by test the inhibition zone of the bacterial indicators of Staphylococcus aureus, Escherichia coli, Candida albicans and Aspergillus niger. And then the shelf life of the Sufan fish with the cover of various films produced on days 0-5-10-15 And 20 days were evaluated, and finally the presence of nano materials was confirmed by FE-SEM. The results showed that the effects of different concentrations of silver nanoparticles and titanium dioxide on growth retardation of Staphylococcus aureus, Escherichia coli 0157, Candida albicans and Aspergillus niger showed significant results (P
