Biodegradable film production from agroforestry and fishery residues with active compounds

An increasing interest in food packaging materials without environmental impact and able to improve shelf life has emerged the last decade. The aim of this work was produce biodegradable films from agroforestry (pine stumps) fishery (chitosan) residues with active compounds. N-carboxybutylchitosan (CBC) were developed inclusion a reinforcing material (cellulose), plasticizers (silicone or glycerol) and/or an antioxidant extract pine stumps. These characterised terms physicochemical properties cytotoxicity. Films glycerol presented higher elasticity, while pure CBC showed most adequate water vapour barrier properties. had thickness values (55–70 ?m) similar commercial ones, slightly hydrophobic (contact angles ? 84–102 °). All revealed low cytotoxicity, exception extract-loaded films. However, these have potential increase decrease photo-oxidation, due their opacity/brown colour.
