Study the Migration Process of Chemical Substances through the PackagingFood Interface during Microwave Treatment

Abstract EN

The diffusion of chemical substances from packaging into food endangers people’s health.

The migration amount of the chemical substances increases with the time and temperature, but the diffusion process for different kinds of packaging materials differs much.

Most recently, the research community showed a renewed interest on the diffusion process of chemical substances through packaging/food interface during microwave treatment.

In this study, the diffusion coefficient model is suggested and then the migration process is studied based on Fick’s diffusion law.

The results are finally compared with the experimental data, showing good agreement.
