Abstract: Inorder todevelop a photodynamically enhanced biodegradable packaging filmand to explore itsapplication inmeat preservation,gelatin,polyvinylalcohol (PVA),andchitosan wereusedasfilm-forming materials,andcurcuminchitosannanoparticles (CCN)asaphotosensitivesubstance.Theefectsofdiferentproportionsofcomponentsonthe tensile strength,elongation at break,and water vapor permeabilitywere investigated.Theeffectof the bilayered filmon fresh pork preservation was evaluated in terms of its mass loss,hardness, pH ,thiobarbituric acid reactive substances (TBARS) value,and totalviablecount (TVC).The results showedthatthefilm witha gelatin toPVAratioof 4:1(V/V),agelatin/PVA to chitosan ratio of 1:5 (V/V),and a CCN concentration of 2.5% (m/m) demonstrated outstanding mechanical and barrier properties. On the 9th day of storage at 4°C ,the TBARS value and TVC of pork wrapped with this film were both significantly lower than those of the control group (P<0.05 )
