Volatile compounds in the natto-fermentating room were absorbed to Tenax-GC in g1ass tube, desorpted by heating, and separated by gas chromatography with DB1 capillary column (60m×0.32mm i.d.; 5 μm film thickness). Each peak was identified by mass pectra of electron-impact ionization, and mass spectra of chemical ionization (methane). Eleven alcohols, 5 aldehydes, 13 ketones, 9 fatty acid esters, 4 pyrazines, 13 hydrocarbons, 5 sulfur compounds, 3 furans, ammonia, and pyrrol were identified.
