Abstract:

The compositions of volatile compounds from congenetic proso millet including whole proso millet (WPM), milled proso millet (MPM) and proso millet bran (PMB) were determined by simultaneous distillation/extraction followed by gas chromatography-mass spectrometry (GC-MS). A total of 69 volatile compounds, including 20 aldehydes, 5 alcohols, 9 ketones, 11 hydrocarbons, 11benzene derivatives, 6 acids and 7 other compounds, were identified in all of the samples. Among these compounds, 50, 53 and 56 were found in WPM, MPM and MPB, respectively. Four compounds (hexanal, (E,E)-2,4-decadienal, hexadecanoic acid and (Z,Z)-9,12-octadecadienoic acid) were dominant among the WPM and MPM materials. Two compounds (hexadecanoic acid and (Z,Z)-9,12- octadecadienoic acid) were dominant among the MPB materials. In addition to the aromatic molecules, which were present in all fractions, compounds present only in WPM, MPM or MPB were also identified.
