| Zusammenfassung: | Robust and reproducible models were developed to predict the sensory profile of espresso coffee from instrumental data using holistic and targeted approaches. The analytical data were obtained either by analyzing headspace constituents by proton transfer reaction mass spectrometry (PTRMS) or by quantifying selected aroma compounds with GC-MS techniques. In both cases the analytical data were correlated with sensory profiles from a trained panel. In the holistic approach, 16 ion traces in the head-space were monitored by PTR-MS. In the targeted approach, several of the 42 aroma compounds exhibited a good correlation to specific sensory descriptorsand may be used as chemical markers. In both approaches, the correlation is based on a knowledge-based standardization and normalization of both datasets that selectively extracts differences in the quality of samples, while reducing the impact of variations on the overall intensity of coffees. Such model is a very useful tool for future development of coffee blends with specific flavour profiles. The results represent a significant progress in correlating sensory with instrumental data exemplified on one of the most complex aromas, i.e. coffee. |
