Correlating Consumer Sensory Experience of Apple Aroma with VOC Profiles Acquired by Automated TD–GC–MS

This study shows that data acquired using the new Centri^® automated multi-mode sampling and concentration system for gas chromatography–mass spectrometry (GC–MS) can be used to generate useful insights into the aroma profiles of foods. In the example investigated, the headspace profiles of two apple cultivars are sampled onto sorbent tubes, which are then analysed on Centri. The results of this analysis are then correlated with consumer sensory experience to highlight key volatiles of interest.
