Packaging based on Ag-Low Density Polyethylene for shelf-life extension of pasteurized and traditional butters at refrigerated temperature

This article focuses on increasing the shelf life of both pasteurized (Pa) and traditional (Tr) butters wrapped in Ag-Low Density Polyethylene (LDPE) film concentration 2.5%, 7.5%, 12.5%, 17.5% at refrigerated temperature up to one month. Silver nanoparticles were synthesized (20.63 nm) through chemical reduction followed by melt mixing method produce Ag-LDPE films. A mixed model-ANOVA Repeated Measurement presented that total bacteria, S. aureus E. coli eliminated from Pasteurized butter samples with Ag/LDPE In comparison, psychrophilic bacteria can be eradicated 2.5-17.5% films after 30d. Peroxide value showed a slight fall 0.50 0.28 meq/kg, respectively for Pa Tr 1st day control group 0.31 0.24 end storage no significant difference (p > 0.05) other treatments. Iodine was decreased It is concluded use as coating safely preserve least
