MetabolomicsEFFECT OF DIFFERENT POOLED QC SAMPLES ON DATA QUALITY DURING AN INTER-BATCH EXPERIMENT IN UNTARGETED UHPLC-HRMS ANALYSIS ON TWO DIFFERENT MS PLATFORMS
Quality control (QC) samples are commonly used in metabolomics approaches for three main reasons: (i) the initial conditioning of the column; (ii) the correction of analytical drift especially between batches; and (iii) the evaluation of measurement precision. In practice there are several ways to p...

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...

MetabolomicsStrong effect of Penicillium roqueforti populations on volatile and metabolic compounds responsible for aromas, flavour and texture in blue cheeses
Studies of food microorganism domestication can provide important insight into adaptation mechanisms and lead to commercial applications. Penicillium roqueforti is a fungus with four genetically differentiated populations, two of which were independently domesticated for blue cheese-making, with the...
