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

Studies report on oligomer migration from food packaging

Scientists perform migration experiments for oligomer analysis; one study detects eight chemicals including six non-intentionally added oligomers to migrate from multilayer biodegradable teacups; second study reports on oligomer migration from polycarbonate tableware as ‘hidden source’ of bisphenol A (BPA)

Two articles review oligomers and other chemicals migrating from bio-based products

Research study compares different techniques for oligomer detection and finds polyester oligomers migrate from biopolymers; book chapter discusses catalysts, volatile organic compounds, and additives in bio-based products, including their migration and safety

Measures to limit chemical migration from recycled paperboard

Review identifies and discusses three approaches to limit chemical migration from recycled paperboard to make it acceptable for food applications; considers internal bags with an incorporated barrier, barrier layers, and functional sorbents added to the board; study on migration from paper cups identifies exposures to vanadium and fluoride

Toxicological and chemical profiling of plastic migrates

Scientific study investigates in vitro toxicity and composition of chemical mixtures migrating from everyday plastic products made of eight polymer types; demonstrates that thousands of chemicals can leach under realistic use conditions, including compounds toxic in vitro that contribute to human exposure; emphasizes the importance to rethink and redesign plastics to achieve safe materials

NIAS migration from plastic wine corks

Scientific study uses non-targeted chemical analysis to provide an overview of chemicals migrating from 8 wine corks made of ethylene-vinyl acetate; identifies 50 compounds, 84% non-intentionally added substances (NIAS); finds one cork not suitable as food contact material

Bioassay-based analysis of chemicals in paper & cardboard

Scientific study evaluates presence of hazardous chemicals in methanolic extracts from paper and cardboard food contact materials (FCMs) using several bioassays; finds oxidative stress (52%), genotoxicity (100%), impacts on xenobiotic metabolism (74%), antiandrogenic (52%) and antioestrogenic effects (39%); recommends an effect-based approach for hazard identification of food contact chemicals
