It is clear that active packaging solutions that do not depend on sachets would be an improvement. There have been attempts to disperse ferrous iron compounds directly into polymer matrices; however, this causes their effectiveness to diminish as the active compound is poorly dispersed or quickly deactivated. The development of new active oxygen scavenging packaging materials with higher levels of efficacy would be of benefit to the food industry. Some oxygen scavenging films have been developed by adding titanium dioxide (TiO2) nanoparticles to different polymers, but since TiO2 acts by a photocatalytic mechanism, its major drawback is the requirement of UV light for activation.4,5 Aerobic microorganisms have also been used as oxygen-scavenging ‘active compounds’ in hydroxyethyl cellulose and PVOH active coatings for high humidity foods,6 but their efficiency is restricted by the hydration conditions and the matrices in which they are entrapped.
