Headspace-solid phase micro-extraction (HS-SPME) coupled to gas chromatography-mass spectrometry (GC-MS) was applied to analyze the volatile compounds of the fresh adlay seeds and those with off-flavor. The results showed: more than 85 of volatile compounds which belonged to distinct chemical families were analyzed. A total of 47 compounds in fresh adlay seeds were identified (including 12 alcohols, 11 aldehydes and ketones and 22 hydrocarbons), the major volatile components in fresh adlay seeds were (+)-Limonene, benzene, 2-pentyl furan, hexanal, 1-nonanal, n-octanal, 2-heptanone, 1-pentanol, 1-hexanol, 1-octen-3-ol and linalool; While, there were 58 compounds in adlay seeds with off-flavor (including 17 hydrocarbons, 8 …
