The key-aroma compounds and the volatile constituents of the flowers of three different industrial hemp varieties (KC Virtus, Felina 32 and Santhica 70) grown during a field study in Switzerland, have been analysed by means of Gas Chromatography-Olfactometry (GC-O) and Gas Chromatography – Mass Spectrometry (GC-MS) in fresh flower samples at different time points of plant growth. The GC-O analysis revealed 33 different odour-active compounds, whereas most of these compounds were detectable in all three hemp cultivars, with different odour intensities. Not only terpenes but also compounds from other substance classes were detected as odour-active constituents. The GC-MS analysis of the terpene constitution in the same samples revealed cultivar-specific differences among the main volatile constituents. Furthermore, changes in the terpene profile could be observed during plant growth. Overall, it could be shown that the flowers of industrial hemp varieties can be regarded as a valuable source of aroma compounds for future food and beverage applications. |
