Three research studies investigate the occurrence of chemicals in food packaging and migration into food; find average of 330 µg oligoesters migrating from cans per kg drained vegetables; report most extractable chemicals from low-density polyethylene Dahi curd packaging not included in India’s positive list; detect low levels of phthalic acid esters in coffee obtained from single-use capsules
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
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
Study analyzes unknown chemicals in recycled plastic
Scientists develop automated non-target approach to identify and risk assess unknown chemicals in food contact plastics; detect over 300 chemical features and tentatively identify 83 compounds in a recycled polyethylene film used as proof-of-concept
New Zealand symposium on food safety
First session of the New Zealand Food Safety Science & Research Centre annual symposium is a webinar on chemical contaminants in food; presentation on New Zealand-wide project to study impacts of microplastics on human health and natural resources; new project developing guidelines to help food industry navigate the use of food packaging containing recycled material
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
Third episode of ‘Unwrapping Food Packaging’ video blog released
Food Packaging Forum publishes third episode of video blog; discusses the presence of non-intentionally added substances in food packaging and the safety and circular economy challenges they pose; reviews the limited enforcement of known chemicals in marketed food packaging, challenges posed by biodegradable packaging, and the approach of prioritizing the most hazardous chemicals
Review investigates challenges of assessing NIAS in plastic FCMs
Literature review summarizes challenges regarding non-intentionally added substances (NIAS) in plastic food contact materials (FCMs); describes 52 studies with their applied methodologies for NIAS extraction and identification, plastic types analyzed, and NIAS detected; highlights NIAS assessment as a challenge for scientific community and industry due to lack of hazard data, a missing harmonized methodology, and outdated regulatory guidelines
Global Food Contact Conference: NIAS evaluation in recycled packaging
2021 Smithers Pira conference covers global developments in food contact regulations and materials including a session on the risk assessment of non-intentionally added substances (NIAS); Marco Zhong outlines efforts China is taking to assess NIAS in recycled and biodegradable materials for safe food contact application; Marinella Vitulli focuses on applied testing schemes for NIAS identification, stresses that the right analytical approach is key
