Volatile components were isolated from freshly harvested and market samples of coriander herb (cilantro) by direct solvent extraction with dichloromethane and analyzed by gas chromatography (GC)-mass spectrometry, GC-olfactometry, and aroma extract dilution analysis (AEDA). Enzyme decompositon of volatiles was minimized by conducting extractions at reduced temperature and in the presence of saturated sodium chloride. Volatile components of both samples were composed mainly of (E)-2-alkenals and alkanals, with (E)-2-decenal and (E)-2-dodecenal, and (E)-2-tetradecenal being the most abundant compounds. Results of AEDA revealed that (Z)-3-Hexenal (green/cut-grass) and an unknown odorant (rancid/ sour/old cut-grass) had the greatest impact on the aroma of fresh-picked cilantro; however, in the market sample (Z)-3-hexenal was not detected and the unknown was at low odor intensity. (E)-2-Alkenals from C9-C 14 and decanal were predominant odorants in both samples. These odorant provided mainly green/cut-grass and fatty/waxy aroma notes. Three unknown odorants, having fresh/swimming pool-like notes, were also found a high intensity in both samples.
