Multifunctional Active Food Packaging Based on Bionanocomposite

To address the concerns of consumers for food safety and freshness, researchers have expanded thefunctions of biopolymer-based food packaging materials by fabricating active food packaging films.Recently, nanostructures and natural componds have received growing attentions in food packaging.In this work, novel active food packaging based on polyvinyl alcohol (PVA)/starch (St) withnanostructures such as zinc oxide, montmorillonite, titanium dioxide and green tea extract weredeveloped via solvent casting method. The structural characteristics of films using FTIR confirmedsuccessfully formation of films in the presence of NPs. The addition of nanoparticles enhanced theswelling and hydrophilicity of the films. Functional properties of the active films such as antioxidantactivity, antimicrobial peroperties, Water vapor barrier performance and degradation will beinvestigated.
