The seeds of the
Brassicaceae are used for edible oil production (rape) or as a pungent flavoring (mustard). Surprisingly by roasting of the seeds coffee-like and popcorn-like overall aroma impressions arise. However, this process is barely used so far. Applying the sensory science concept to characterize changes in aroma-active compounds induced by roasting of the raw seeds led to the characterization of the key odorants after the thermal treatment and their possible formation pathways. Especially high odor activity values were found for 2-furanmethanethiol, dimethyl trisulfide, 3-methylbutanal, and 2-acetyl-1-pyrroline in the roasted seeds.
