Abstract:

The flavor components in soybean tempeh and soybean-sorghum tempeh fermented by Rhizopus oligosporusaito
RT-3 were analyzed by SPME-GC-MS. Results showed that 18 volatile components were detected in soybean tempeh,
while 20 were detected in soybean-sorghum tempeh. 3-Hydroxy-2-butanone and trans-caryophyllene were detected
only in soybean-sorghum tempeh. 1-Octen-3-ol, which was responsible for a mushroom-like aroma was detected in both
kinds of tempeh.

Key words: Rhizopus oligosporusaito RT-3, soybean tempeh, soybean-sorghum tempeh, solid-phase micro-extraction(SPME)-gas chromatography-mass spectrometry (GC-MS), volatile components
