Due to their pleasant sulfury-roasty aroma, roasted sesame seeds are polpular as topping and flavoring for a variety of dishes in Asian cousines. In the western world, they are e.g. used as topping for bakery products and snacks. Using a molecular sensory science approach, 29 aroma-active substances were structurally characterized in freshly roasted sesame seeds. Among these, five odorants exhibited a sulfury-meaty odor together with a 1-alkene-1-thiol structure, thus constituing a new, previously unknown class of aroma compounds. A comparison of the concentrations of the individual odorants with their respective odor thresholds showed that particularly 2- and 3-methyl-1-butene-1-thiols are important for the overall aroma of roasted sesame seeds.
