Developments in Mycotoxins Analysis

This on-demand presentation will cover the use mass spectrometry for mycotoxin analysis, from multi-toxin methods to the most advanced methodologies. Challenges such as mycotoxin chemical diversity, the large number of isomeric forms, and the lack of analytical standards, will be addressed.

Mycotoxins are secondary metabolites produced by pathogenic fungi in crops worldwide. These compounds can undergo modification in plants, leading to the formation of a large number of possible modified forms, whose toxicological relevance and occurrence in food and feed is still largely unexplored. In this frame, liquid chromatography coupled with mass spectrometry has represented the golden standard for at least a decade. However, novel approaches based on HR-MS and ion mobility may offer new opportunities for method development and compound identification. The presentation, given by Chiara Dall’Asta (Department of Food and Drug, University of Parma, Italy), will cover the use mass spectrometry for mycotoxin analysis, from multi-toxin methods to the most advanced methodologies. Challenges such as mycotoxin chemical diversity, the large number of isomeric forms, and the lack of analytical standards, will be addressed. The potential benefits of high-resolution and ion mobility mass spectrometry as a tool for separation and structure confirmation of modified mycotoxins will be introduced.

The key learning outcomes from viewing this presentation are:

  • overview of common MS based approaches for (multi)toxin analysis
  • use of untargeted HR-MS for unknown identification
  • use of Ion Mobility for structural characterization and database acquisition

Prof. Chiara Dall’Asta is Associate Professor in Food Chemistry at the University of Parma. Her research activity is focussed on the MS-based investigation of the formation, stability and toxicological relevance of natural toxins in food, mostly mycotoxins. In this field, Chiara has published +130 papers and several book chapters. Since 2014 she has been involved as expert in several EFSA Working Groups, and has co-authored a number of scientific opinions on modified mycotoxins. Chiara is member of the editorial board of the World Mycotoxin Journal, of Scientific Reports, and of the International Journal of Food Science and Nutrition.
