Professor Ernst Rank and the TUM-IAS team invite the scientists of TUM and their guests for coffee each Wednesday. Just come over to the TUM-IAS after lunch between 1:00–2:00 pm and have a coffee with us, meet other scientists and listen to a short talk (10-15 mins) on a recent major TUM publication or issue – aimed specifically at a non-expert audience.
On November 27, Andreas Dunkel (Leibniz-Institute for Food Systems Biology at TUM) will talk about „New High-Throughput Tools for Volatile Metabolite Quantitation in Food Analysis and Nutrition Science“.Whether a food tastes good or not is essentially determined by the interaction of odors and tastants. A few trillionths of a gram per kilogram of food is enough to perceive some odorants. Tastants, on the other hand, humans only recognize at significantly higher concentrations. In order to guarantee consistent sensory quality, it is very important for manufacturers to know and control the characteristic odor and taste profiles of their products from the raw material to the finished product. This requires a fast but precise food analysis. The new and time-saving feature of the developed approach is that volatile odorous substances can now also be analyzed by means of an upstream enrichment or substance conversion step using this method, which is otherwise not used for aromatic substances.
