Migration per- und polyfluorierter Chemikalien aus Butterwicklern

Coatings of side-chain fluorinated phosphate esters and polymers on nonstick food contact materials could contain perfluorinated acids (PFAA) and fluorotelomer alcohols (FTOH), which may pose a possible route of contamination for food. This study assesses the impact of coated butter wraps on PFAA
and FTOH levels in butter. Butter was stored in butter wraps and analysed for their content of per- and polyfluoroalkyl substances (PFAS). An increase of the PFAA and FTOH levels in butter were
detected with 0.061 ng/g PFAA and 36.4 ng/g FTOH, respectively. Migration of PFAA was found to decrease with chain length indicating an inhibiting effect of higher molecular size.
