MetabolomicsUntargeted food contaminant detection using UHPLC-HRMS combined with multivariate analysis: Feasibility study on tea (Dataset 2 - Validation)
Powerful data pretreatment strategies inspired from the field of metabolomics were adapted to chemical food safety context to enable samples discrimination by multivariate methods based on low abundance ions. A highly automated workflow was produced. The open-source XCMS package was used and efficie...

MetabolomicsUntargeted food chemical safety assessment: A proof-of-concept on two analytical platforms and contamination scenarios of tea (Black tea study)
This study aims at assessing the capability of comparing and combining different instrumental platforms in an untargeted approach with a view of detecting chemical contaminants in food matrices at low levels. A strategy based on liquid chromatography-high resolution mass spectrometry (LC-HRMS) and c...

MetabolomicsFood Deprivation Enhances Disease Resistance: Underlying Mechanisms in Oysters Confronted with Pacific Oyster Mortality Syndrome

Variation in food availability can shape host susceptibility and pathogen virulence, thereby impacting disease outcomes. An ad libitum diet may enhance host physiology and immunity but it can also favor pathogen proliferation. Here, we investigated how food availability (ad libitum vs. starvation...

MetabolomicsThe metabolic response of marine copepods to environmental warming and ocean acidification in the absence of food
Marine copepods are central to the productivity and biogeochemistry of marine ecosystems. Nevertheless, the direct and indirect effects of climate change on their metabolic functioning remain poorly understood. Here, we use metabolomics, the unbiased study of multiple low molecular weight organic me...

MetabolomicsAntimicrobial Efficacy of Bifidobacterium longum FB1-4 Cell-Free Supernatant Against MRSA: Insights into Mechanisms and Food Matrix Application

The food safety landscape faces a significant challenge from methicillin-resistant Staphylococcus aureus (MRSA), a virulent and antibiotic-resistant foodborne pathogen. This study investigates the antimicrobial properties and mechanisms of cell-free supernatant (CFS) from Bifidobacterium longum F...

MetabolomicsTitanium dioxide in food induces sex- and microbiota-dependent metabolic disorders, and worsens high-fat diet outcomes
Ultra-processed food consumption has been linked to the rising global burden of metabolic diseases, but the specific contribution of additives commonly used in these products remains unclear. Given the bactericidal properties of the food-grade (fg) additive titanium dioxide (TiO2) and the key role o...
