Evaluation of anti-bacterial property of modified Nano silver packaging with Photocatalyst TiO2 in sheep's head and trotters

Head and trotters sheep is traditional food in Iran. This product has very microbial load then for first time determine to done it. The current study was designed to evaluate application of silver nanoparticles, as an antimicrobial agent. Effect of Nano silver packaging in reduce microbial load in head and trotters compare with Control sample in the Refrigerator for 4°C for 1,2,3,4 days. Minced Head and trotters sheep (100g of product has 15 g fat, 90 ml⁄gr Cholesterol). this product has bought at Shahrvand mall. Nano - silver coating based on titanium dioxide was used to reduce the microbial load of the product. some Nano-coating of silver on titanium dioxide at a concentration of ppm 1000, 2000, 3000, 3500 and 4000 used at this study. For measurement nanoparticles size used Field Emission Scanning Electron Microscope (fesem) and to know Chemical bond used. The results showed The concentrations of silver nanoparticles ppm 4000 ppm 3500 on Escherichia coli maintaining the relative amounts of byproducts in four days of testing on impact (p
