🎓Microspectroscopic investigations for the determination of surface contamination on chemically complex background matrices in food safety (completed doctoral thesis)

Doctoral project at a glance

Raw meat quickly shows bacterial contamination. If the contaminated meat is consumed, it can be hazardous to health above a certain amount. That is why doctoral student DANIEL KLEIN has made contamination (e.g. bacteria) visible on complex surfaces (e.g. meat). To do this, he combined spectroscopic data from IR and Raman spectroscopy from the same measurement regions to show where contamination can be found. Combining the two methods increases the information content of the data set and at the same time reduces the error rate in contamination detection.
