Abstract
Volatile carbonyl components of the MUGI-CHA flavor were converted to mono 2, 4-dinitrophenylhydrazones (2, 4-DNPHs) and his 2, 4-DNPHs. The volatile mono 2, 4-DNPHs were subjected to gas chromatography and fourteen peaks were detected. Among those, twelve 2, 4-DNPHs were isolated in crystalline form by using column and thin-layer chromatographies. These compounds were identified by their IR, UV-spectra and mixed melting point test. Compounds identified are methanal, ethanal, propanone, 2-methyl propanal, 2-methylbutanal, 2-butanone, 3-pentanone, 2-methyl-3-pentanone, furfural (syn, anti), and 5-methylfurfural (syn, anti).<br> 2-Methyl-3-pentanone had a characteristic menthol-like flavor, but the dilute solution had sweet flavor which is one of characteristic flavors of roast barley.
