Review summarizes per- and polyfluoroalkyl substances (PFAS) migration from paper food packaging into food and food simulants and identifies dietary exposure of PFAS as potential human health risk; study highlights need to further evaluate organophosphate esters (OPEs) and prohibited PFAS in paper and aluminum foil food packaging; scientists analyze and recommend extraction method to assess plasticizers in recycled paperboard.
Lerch and co-authors evaluated the methodological approaches scientists apply to analyze PFAS migration from paper FCMs. They summarized that most studies looked at PFAS in real food or food simulants and quantified certain PFAS by liquid chromatography followed by tandem mass spectrometry (LC-MS/MS). While in Europe currently no regulations exist on how to perform migration experiments on paper FCMs the Council of Europe recommended deploying those developed for plastic FCMs. This approach is also the one chosen most commonly in scientific analysis. Lerch et al. pointed out that “knowledge regarding the migration behavior of PFAS from paper-based FCMs is scarce” especially concerning factors potentially influencing PFAS migration such as material properties (e.g., thickness), composition, and unintended or misuse of packaging. Moreover, they emphasized, “that the use of food simulants (especially Tenax®) in migration tests lead to an underestimation of PFAS exposure from FCMs.”
