Migration of Mineral Oil Saturated and Aromatic Hydrocarbons(MOSH, MOAH) through Multi-Layered Packaging into Food
Substances like Mineral Oil Saturated Hydrocarbons (MOSH) and Mineral Oil Aromatic Hydrocarbons (MOAH) are suspected to be carcinogenic. Furthermore, MOSH/MOAH migrate through the packaging into food stuff. This work aims at modelling, how much MOSH/MOAH migrates from the packaging into food to evaluate the exposure to toxic substances. The scope of the project is not to investigate one specific packaging, but to develop a tool that can be used for the simulation of a broad variety of packaging solution. Accordingly, instead of constructing the packaging consisting of several layers by hand, the LiveLink™ for MATLAB® is used to build a packaged food with an arbitrary number of layers. The migration of MOSH/MOAH can be described by Fick’ian diffusion. Within the packaging can be adsorbents for MOSH/MOAH which are considered by a reaction term. Because MOSH/MOAH are groups of chemically similar substances with different molecular weights, the transport of several representative species is computed. The diffusion coefficients are computed by empirical correlations in MATLAB®.
