Proposal title: Direct Ambient Ionization Mass Spectrometry for real time classification of food quality
The frequent occurrence of food scandals in the world has led to an increase in the public awareness of food safety and quality. All over the world, competent authorities implement strategies to up-grade the food supply system to a high food safety standard. In particular, regarding chemical risks, such strategy relies on laboratory testing services for the detection and quantification of food contaminants. While being extremely efficient, those are limited by sophisticated sample preparation procedures, long analysis time, large (expensive) instruments and experienced staff. Thus, to face the increasing demand, fast and accurate analytical platforms are required. To that end, metabolomics offers a promising approach. Developing a high-throughput metabolomics workflow directly applicable for sampling food items, empowering immediate prediction of its quality or chemical status would be considered a major breakthrough. Recent developments in ambient ionization mass spectrometry, such as Atmospheric Solids Analysis Probe (ASAP) or Rapid Evaporative Ionization Mass Spectrometry (REIMS) open a whole new dimension for rapid (sec) screening of food samples. Both technologies enable point-of-control analysis. In proof of concept studies, ASAP has for example demonstrated to segregate solid or liquid samples based on their chemical profile. For solids samples, REIMS was proposed as a new analytical approach for in-situ detection of a number of food anomalies or chemical residues.
Main objective of the program: The current project aims at confirming, REIMS and ASAP, as valuable in-situ high throughput monitoring tools, whereby rapid characterization of food products is a requisite. Three different applications related to food quality issues will be evaluated (pig meat quality / forbidden residues in livestock / historical and emerging contaminant (PCBs & BPA) exposure in livestock)
