The group of Prof. Dr. Hans-Ulrich Humpf is interested in the biosynthesis, toxicity and (intestinal) metabolism of mycotoxins as well as the thermal stability during food processing. Further focus is given to the development of human biomonitoring methods (HBM) to evaluate the exposure to mycotoxins and metabolomics-based approaches to analyze nutritional habits. Moreover the transfer of food constituents across the intestinal barrier (Caco-2 model) as well as the blood-brain-barrier is studied.
