wheat soybean pastes. In our laboratory, we have successfully
applied headspace solid-phase microextraction (HS-SPME) and gas
chromatographyemass spectrometry (GCeMS) in the identification
of volatile compounds of natural fermented Chinese soybean paste
(Zhao, Gu, Liu, &Wang, 2006), inwhich wheat, instead of rice, is used
as fermentation ingredient. A Korean research group studied the
volatile compounds in Korean fermented soybean pastes by simultaneous
steam distillation and extraction (SDE) and GCeMS (Lee &
Ahn, 2009). However no detailed research has been conducted on
the difference in the aroma active compounds of traditional fermented
and inoculated fermented Chinese soybean pastes.
