  • Propanethiol the main odor source: sulfurous, pungent, fresh-cut onion
  • Dipropyl disulfide mellower cooked-onion aroma with a slightly nutty undertone
  • Methyl propyl disulfide green, alliaceous note typical of cooked onion and scallion
  • Dimethylthiophene formed on frying: the characteristic fried, toasted onion aroma
