Safety of new food contact materials: Migration and sorption studies based on Tenax, powdered milk, baby cereal and oat flakes

This paper presents migration tests of environmental and production contaminants, migrating from food contact materials (FCMs) into Tenax. Migration tests were conducted under two time and temperature conditions (2 h, 70 °C, 10 days, 40 °C). Various chromatographic methods (GC/FID, GC/ECD, GC/MS, HPLC/DAD) were used to identify and quantify the migrants. The specific surface area and pore distribution of Tenax and food samples were also characterized. Plant-based FCMs do not pose a risk of phenanthrene and anthracene migration into Tenax. In turn, carbonyl compounds can migrate after short and long contact between the FCMs and food simulant. However, aldehydes may degrade with prolonged contact of food with FCMs. In addition, BPA, BPS, benzophenone derivatives and phthalates may migrate from the FCMs into Tenax. Moreover, some contaminants can migrate at concentrations above the specific migration limits (e.g. BPA). The intensity of migration process may depend on the structure of the molecule and the size of the substituents.
