The main aim of the work of this PhD was to investigate the need and the applicability of a fast and easy method in order to define quantities when transport phenomena are under investigation. The outcome of this work is the proposal to go beyond the consideration of the diffusion process as being the single mechanism to describe the migration from packaging to foodstuffs, but rather to incorporate more complicated phenomena (sorption, surface reactions, etc.) to overcome the above‐mentioned discrepancies. Overall, in the present thesis the transport phenomena, were analytically studied from modelling point of view and it was proved that the use of simulation with a computerized mathematical model imitates the behavior of a real-world process or system over time. Simulations are used to describe and analyze the behavior of a system when asking "what-if" questions about real-life systems. Furthermore, mathematical models could be very helpful tools for designing artificial systems, while the easy and quick description of phenomena occurring in porous media could be feasible.
