OptiBarrier is a VIS-range around the central problem: on hold versus under packaging. The program consists of three sub-processes. In the first section, the effect of different levels of gas-barrier is studied, resulting in different dynamic oxygen concentrations on the shelf-life of foodstuffs. The second sub-project zooms in on the light-barrier packaging, and more concretely on the interaction between light exposure, light transmittance of the packaging, the dynamic oxygen concentration in the packaging Kung and the resultant shelf-life of foodstuffs. The third project is investigating how a functional barrier can be integrated into packaging materials (specific) migration (eg. Mineral oil) to reduce the food from these materials.
