AROMA OF WHITE VINE BLOSSOMS - CORRELATION OF SENSORIC DATA WITH HEADSPACE CONSTITUENTS

Using headspace-analysis in combination with gaschromatographic-spectroscopic methods (GC-FID and GC-FTIR-MS) as well as with the GC-sniffing-technique it was possible to correlate blossoms of 7 different vine-varieties by means of the composition of odor compounds in their headspace considering only odor-dominant sesquiterpenes and odor-assistant monoterpenes. - All investigated vine-blossoms possess a mignonette-like, pleasant, floral, dusty, dry, interesting, green, fresh, intense and sweet odour and with regard to the vine-species they only differ in the intensity of single odournotes, but not in the direction of the total odour. The odour-profiles and the corresponding multivariate data analysis of these profiles showed a significant agreement with those results, which were obtained by correlations of headspace constituents. - The possibility of further connectivities with the corresponding ampelographic aspects of the investigated vine-species is also discussed.
