Toasted sesame seed oil was comprehensively analyzed. It was extracted using the SAFE (Solvent‐Assisted Flavor Evaporation) technique. The extract was analyzed by GC and GC‐MS on 2 phases and a total of 87 components were identified, confirmed, and are presented in this paper. The major components were methylpyrazine; 2,5‐dimethylpyrazine; 2,6‐dimethylpyrazine; 2‐ethyl‐3,6‐dimethylpyrazine; furfuryl alcohol; and guaiacol. In addition, as part of this analysis, 2‐ethyl‐4‐methyl‐3‐thiazoline and 2‐isopropyl‐4‐methyl‐3‐thiazoline were confirmed as being present in a natural product for the first time. Their identification, confirmation, and sensory evaluation have been documented here.
