dc.description.abstracttAn antimicrobial packaging material was developed by uniformly embedding 1, 3 and 5% chitosan (w/w)in low density polyethylene matrix using maleic anhydride grafted LDPE as a compatible agent. Thematerials were mixed by compounding and blown into monolayer films via blown film extrusion. Thedeveloped films showed good barrier properties against oxygen. Characterization of the composite filmswith Fourier transform infrared spectroscopy revealed that chitosan and LDPE interacted well with eachother. Overall migration showed better release of chitosan adduct from the LDPE matrix which enhancedthe antibacterial properties of the films. The interaction between the LDPE/CS and maleic anhydridegrafted LDPE had a decreasing effect on the tensile strength and heat sealing properties. Investigationon antimicrobial properties of LDPE/CS films showed 85–100% inhibition of Escherichia coli. Efficacy ofLDPE/CS films was evaluated by using them as packaging material for chilled storage of Tilapia (Ore-ochromis mossambicus). Analysis of storage quality indices (peroxide value, free fatty acid, total volatilebase nitrogen and aerobic plate count) revealed good antibacterial property and extension of shelf life ofTilapia in the chitosan incorporated novel composite films compared to virgin LDPE film.en_US
