Propose method to analyze chemical markers of mineral oil aromatic hydrocarbons (MOAH) from printing inks in food packaging; present workflow that includes in silico prediction tools to identify nonvolatile migrates from food packaging; evaluate efficiency and reliability of methodology for non-target identification of volatile substances
Oligomers from plastic FCMs reviewed
The diversity of oligomeric migrants increases with new (co)monomer varieties used in plastic production; quantitative analysis and toxicological evaluation are challenging
New research on chemical migration from plastic, paper, can coating, and reusables
Recent reports investigate whitening agents’ migration from disposable plastic containers; characterize 153 chemicals migrating from paper packaging and show estimated dietary exposure for children to per- and polyfluorinated alkyl substances (PFAS) exceed safety threshold; detect brominated flame retardants in repeat-use food contact articles; review metal can coating literature concerning coatings types, chemical migrants, detection methods, dietary exposure, and regulatory
New NIAS detected in polyester-phenolic can coating extracts
Scientists analyze non-intentionally added substances (NIAS) extracted from six model polyester-phenolic can coatings; identify cyclic polyester oligomers and new aldehydes
Studies investigate extractable and leachable FCCs, present collision cross section database
Scientists develop collisions cross section (CCS) database for leachable and extractable food contact chemicals (FCCs) to help in chemical identification during targeted and untargeted analysis; database covers 1038 CCS values; study tentatively identifies >100 migrants from 24 plastic food packaging articles including 11 that are of potential concern or are priority hazardous substances
How much styrene is contained in packaged food: A scientific review
Systematic literature review identifies eight studies analyzing styrene levels in food; reports average level of 91.53 µg styrene/kg food; highlights knowledge gaps on other foodstuff besides dairy products
Scientists propose and apply NIAS identification approaches
Review provides guidance to select analytical technique for non-intentionally added substances (NIAS) identification and quantification in food contact materials (FCMs); scientific studies analyze NIAS migrating from FCMs; develop model to predict collision cross-section values to identify NIAS in FCMs; detect polyethylene terephthalate (PET) oligomers in post-mortem blood samples
Hundreds of chemicals migrate from reusable plastic bottles
Scientific study compares chemicals migrating from new plastic sport bottles and bottles after dishwashing and one year in use; detects over 400 plastic-related compounds including oligomers and aromatic amines; finds dishwashing to increase migration
Peer-reviewed study finds chemicals in plastics induce adipogenesis
Researchers analyze plastic extracts for their chemical composition and promotion of obesity; find one-third induce fat production (adipogenesis); detect several thousand chemicals in the extracts, including known metabolism-disrupting chemicals
Several studies determine chemical migration from food packaging
Researchers from several European and Chinese institutions develop methods to explore chemicals in food contact materials (FCMs); report styrene migration from different polystyrene FCMs into several food matrices; detect photoinitiators in paper FCMs and chlorinated paraffins in green tea and its packaging; find irradiation treatment of metalized polypropylene to reduce migration of tested chemicals
