Abstract:

The migration of phthalates from microwave paper to the food stimulant Tenax (modified polyphenylene oxide)
was determined through experiments. At the same time, prediction models were built, respectively, based on the Fick’s
second law and the Weibull distribution theory. The predicted values from the Fick’s migration model, which was based on
finite packaging volume, finite food volume and worst-case, were higher than the experimental data. The predicted result
could be used to assess food safety and provides a higher safety threshold. The predicted values from the Weibull migration
model, which was based on experimental experience, could describe effectively the actual migration process.

Key words: phthalates (PAEs), migration experiment, Fick’s second law, Weibull distribution, migration model
