Modelling migration from paper into a food simulant

Abstract

a b s t r a c tThe migration of components from paper into Tenax Ò was studied to determine the influence of molecular size and chemical character of the migrant and the influence of paper characteristics in the migration process. The Weibull model was applied because Fick's 2nd law of diffusion gave poor fits in some cases. The migration pattern depended on the migrants molecular size and was independent of temperature in the studied range. The migration rate decreased with the migrant molecular size. The influence of the migrants character (polarity and vapour pressure) on the migration behaviour was also studied: nonpolar migrants with high vapour pressure presented low relative migration values and polar migrants presented high values of relative migration. Results indicated that the apparent partition coefficient between paper and the simulant Tenax Ò increased with the migrant vapour pressure and with both the paper grammage and the recycled pulp content.

Migration of two antioxidants from packaging into a solid food and into Tenax®

“…Equation (1) does not describe very well the migration at very early times at lower temperatures. Similar results were obtained in other studies of migration into Tenax Ò (Poças, Oliveira, Pereira, Brandsch, & Hogg, 2011). The standard error (ε) of the model is also presented.…”

Optimum pH for the determination of bisphenols and their corresponding diglycidyl ethers by gas chromatography–mass spectrometry. Migration kinetics of bisphenol A from polycarbonate glasses

“…If achieved, the resultant model would involve a more economical methodology that would reduce the time-consuming and laborious steps of sample treatment and analysis as much as possible by only knowing the number of migration tests performed and the concentration of BPA in the food simulant after the first migration test. Different mathematical functions have been proposed to describe the behavior of other migrants from plastic materials [19][20][21][22][23].…”

Potential Food Safety Concerns in Fried Potato Products in Kenya

“…Chemical migrants, however, will depend on the type and amount of food, temperature and molecular size of the chemical in packaging material [77] [78]. The negative effects of these migrants to food safety can no longer be over looked if safety of the food supply is to be assured [79].…”
