The safe use of recycled paper and board material for food packaging applications is a major area of investigation. Studies on the migration of contaminants into foods and food simulants have been carried out to evaluate the suitability of recycled paperboard for direct food contact applications. In the present study, the kinetics of migration of selected model contaminants (surrogates) from paper packaging samples into an alternative or substitute fatty food simulant (Tenax) was studied with the aim of developing a rapid test method based on solvent extraction, gas chromatography (GC)-mass spectrometry (MS) identification and GC-flame ionization detector (FID) quantification. These tested substances represent a large number of molecular sizes and polarities and are among those that may be present in fiber material. Crucial data about the time needed to reach equilibrium between paper samples and the food simulant were obtained. The results of the study indicate that time and temperature conditions are the most important variables with respect to the actual mass transfer during contact with food simulants. The proposed quick test method seems to be suitable for compliance testing of paper and board samples if migration limits are applied in future legislation.
