In order to better understand the performance of food products during the actual process of eating, it is important to develop techniques that allow exploring foods in-vivo and in real-time during consumption. Here we present first results on the simultaneous anal. of the eating process, combining two techniques. This includes real-time magnetic resonance imaging (MRI) to visualize the mastication, breakdown and swallowing and online nose-space anal. by proton-transfer-reaction mass-spectrometry (PTR-MS) to monitor the in-mouth aroma release
