Migration of mineral oils and DIPN from paperboard into dry foods

Swiss and Italian researchers publish new study comparing the effect of different testing and storage conditions on migration behavior of MOSH, MOAH and DIPN from paperboard into non-fatty dry foodstuffs. Observed levels of migration were in the part per million (ppm) range (mg/kg food). Migration levels were highest for egg pasta packaged in paperboard and enclosed in an outer polypropylene bag.

Chemical characterization of post-consumer and recycled plastics

Scientists perform target and non-target screening of recycled plastics and provide recommendations on methods; detect >280 organic chemicals and metals in 21 plastic flakes and pellets used in recycling; analyze several recycled polymers and find polyethylene terephthalate (PET) the only one currently complying with European circular economy requirements; compare analytical methods to assess the chemical composition of recyclates giving their strenghts and limitations

Plastic recycling: company commitments and chemical safety challenges

Scientists report most large companies commit to reducing plastic pollution but focus on recycling; extrusion of recycled materials and legacy compounds in recycled materials as safety challenge; some substances increase others decrease with the increase in recycled content in polyethylene terephthalate (PET) bottles; tentatively identify 212 volatile chemicals in 57 different recycled PET flakes available in China; present migration model to characterize the exposure and risk of PET oligomers

EFSA assesses 2 substances for use in FCMs

EFSA’s CEF Panel considers α-tocopherol acetate safe for use in polyolefins and concludes that migration of zinc from nanoparticles in non-plasticized polymers complies with the current SML, however concerns exist over dietary exposure from other sources
