Harmonized 1 H NMR Workflow Enables Quantitative Betaine Determination from Nontargeted Metabolite Profiling Using Internal and External Standards

Biagia Musio, Maria Trisolini, Rosa Ragone, Stefano Todisco et autres

High Resolution Image Download MS PowerPoint Slide Nontargeted metabolite profiling prioritizes robust comparisons of the analytical outcomes rather than absolute concentration measurement. In this work, it is shown that a harmonized 1D 1 H NMR workflow, originally adopted for nontargeted NMR analysis, …

An interlaboratory validation study for the assessment of low limits of quantification for PFAS in foods of plant origin

Consolato Schiavone, Francesco Romaniello, Christina Riemenschneider, Alexander Schächtele et autres

Per- and polyfluoroalkyl substances (PFAS) extensively contaminate the environment and can enter the food chain. Fruits and vegetables represent a significant, yet under-regulated, human exposure pathway due to the uptake of PFAS by plants from contaminated soil/water. PFAS exposure is linked to …

Reliable and sensitive ultra-short chain per- and polyfluorinated alkyl substances (PFAS) analysis in food: a polar reverse-phase chromatography approach

Consolato Schiavone, Francesco Romaniello, Paola Brizio, Michele Suman et autres

Food contamination by per- and polyfluoroalkyl substances (PFAS), especially ultra-short-chain (USC) compounds, poses a growing concern due to their environmental persistence and potential health risks. Despite the developing regulatory framework, analytical challenges persist in quantifying polar USC-PFAS in complex content food matrices. …
