Application of a sensomics approach on white asparagus (
Asparagus officinalis L.) as well as on pepper (
Piper nigrum L.), including instrumental analytical techniques combined with human sensory tools enabled the mapping of intense sensory-active nonvolatiles. Liquid chromatography/mass spectrometry as well as NMR experiments led to the discovery and structure determination of nine bitter tasting and two previously not reported glycosides, which evoke a new asparagus like mouthfeel as the key molecules imparting a sensory oral sensation of white asparagus spears. In addition, 25 sensory active amides were identified in black peppercorns in the present study. On the basis of these data, variety specific taste differences of both foodstuffs can be objectified and growing programs can be knowledge-based optimized.
