- Abstract
The migration of chemicals from packaging materials into food is predictable by various mathematical models. However, the loss of chemicals makes the predictions more complicated. In this article, a mathematical model considering chemical instability is developed to quantify the release of chemicals through doublelayer packaging films based on Fick's diffusion and first order reaction. At the same time, two different loading modes are considered in the loss function. The release model is solved numerically to elucidate the effects of diffusivity value, distribution of chemical and mass transfer at the interface of material and food on the migration process, and the loss of the chemicals in food is also elucidated.
