The potent odorants of boiled potatoes were screened by aroma extract dilut
ion analysis, aroma extract concentration analysis, and gas chromatography-
olfactometry of static headspace samples. Altogether 45 odorants were found
of which 42 were identified. trans-4,5-Epoxy(E)-2-decenal, methional, 2-ac
etyl-1-pyrroline, dimethyltrisulfide, 2,3-diethyl-5-methylpyrazine, vanilli
n, sotolon, decanal, (E,E)-2,4-nonadienal, (E,E)-2,3-decadienal, (E)-beta-d
amascenone, furaneol, methanethiol, 3-isopropyl-2-methoxypyrazine, dimethyl
sulfide appeared in at least one of the three screening experiments with a
higher flavour dilution factor.
