 "The volatile components of cucumbers and muskmelons were analyzed by a technique which reveals the odorants having the highest odor units (ratio of the concentration to the odor threshold). (E/Z)-2,6-Nonadienal, followed by (Z)-2-nonenal and (E)-2-nonenal were the most significant odorants of cucumbers." \\ "The volatile components of cucumbers and muskmelons were analyzed by a technique which reveals the odorants having the highest odor units (ratio of the concentration to the odor threshold).

 "The volatile (E,Z)-2,6-nonadienal (NDE) gives cucumber its 'fresh green' flavor and confers resistance to some bacteria and fungi. Lipoxygenase and one type of hydroperoxide lyase, 9-HPL, synthesize NDE from linolenic acid precursors. Genes encoding enzymes with 9-HPL activity are rarely found in other plants. However, cucumber contains two tandem HPL genes, one of which has been experimentally confirmed as encoding an enzyme with 9-HPL activity. The expansion of the LOX gene family and the duplicated HPL genes may be related to the high level of NDE synthesis in cucumber." \\ "The volatile (E,Z)-2,6-nonadienal (NDE) gives cucumber its 'fresh green' flavor and confers resistance to some bacteria and fungi.
