Starch-chitosan bilayer films, containing or not essential oils in the casted chitosan layer were obtained by thermo-compression. Bilayer films exhibited a good interfacial adhesion and better mechanical resistance than starch monolayers, although they were less stretchable and less transparent. Starch-chitosan films were effective at controlling the bacterial growth in pork meat, but the thermal...
Active packaging from nanocomposite of chitosan and nanosized titanium dioxide (TiO2) to be used as an ethylene scavenging and antimicrobial film was developed. Chitosan films containing different TiO2 concentrations (0, 0.25, 0.5, 1 and 2% w/w) were fabricated and characterized for structural, mechanical, optical and barrier properties. The scanning electron microscope images showed that TiO2 nanoparticles...
