A real time monitoring of main volatile compounds released during cucumber and tomato fruit tissue disruption was measured by atmospheric pressure chemical ionization-mass spectrometry (APCIMS). This technique showed promise for simple, rapid, and artifact-free method for monitoring the rapid volatile release. The key volatiles of fresh cucumber were mainly attributed to C-6 aldehydes (hexanal and (E)-2-hexenal) and C-9 aldehydes ((E)-2,(Z)-6-nonadienal and (E)-2-nonenal) whereas only C-6 aldehydes were responsible for the predominant compounds of fresh tomato volatiles. Both C-6 and C-9 aldehydes were enzymatically produced through the fatty acid oxidation pathway during plant tissue disruption. The combination gas chromatograph (GC) with simultaneous electron impact (EI) and APCIMS was also used to confirm the identification of these volatile compounds in fresh cucumber and tomato fruits.
