The volatile compounds from brown millet (BM), milled millet (MM) and millet bran (MB) were extracted using simultaneous distillation/extraction with a Likens-Nickerson apparatus. The extracts were analysed using gas chromatography coupled with mass spectrometry (GC-MS). A total of 65 volatile compounds were identified in all of the samples. Among these compounds, 51, 51 and 49 belonged to BM, MM and MB, respectively. Aldehydes and benzene derivatives were the most numerous among all of the compounds. Three compounds (hexanal, hexadecanoic acid and 2-methylnaphthalene) were dominant in the BM and MM materials. Eight compounds (hexanal, nonanal, (E)-2-nonenal, naphthalene, 2-methylnaphthalene, 1-methylnaphthalene, hexadecanoic acid and 2-pentylfuran) were dominant in the MB materials. Apart from the aromatic molecules, which were present in all fractions, compounds present only in BM, MM or MB were also identified. © 2012 by the authors.

The volatile compounds in foxtail millet sake were extracted by headspace solid-phase microextraction (HS-SPME) and analyzed using gas chromatography-mass spectroscopy (GC-MS). Different methods of sample preparation were used to optimize this method (SPME fiber types, sample amount, extraction time, extraction temperature, content of NaCl, and rotor speed). For final method of sample preparation, 8 mL of sake was placed in a 15 mL headspace vial with addition of 1.5 g of NaCl; a 50/30 m DVB/CAR/PDMS SPME fiber was used for extraction at 50°C for 30 min with 10 rpm continuous stirring. A total of 41 volatile compounds were identified from the sake sample, including 9 esters, 6 alcohols, 4 acids, 4 aldehydes, 9 hydrocarbons, 7 benzene derivatives, and 2 others. The main volatile compounds were ethyl acetate, phenylethyl alcohol, butanedioic acid diethyl ester, and hexadecane. According to their odors active values (OAVs), 10 volatile compounds were established to be odor active compounds and to contribute to the typical foxtail millet sake aroma. Hexanoic acid ethyl ester was the most prominent odor active compound. © 2015 Jingke Liu et al.

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.
