It generally takes 6-10 months for traditional fermented
Chinese soybean pastes to achieve desirable flavor, which is timeconsuming.
Many efforts have been made to enhance the production
efficiency and quality consistency of Chinese soybean pastes,
including the development of inoculated fermentation process.
However, the flavor of Chinese soybean pastes from industrial
fermentation with inoculation is generally perceived to be less
intense in aroma when compared with natural fermented products.
In order to improve the aroma of the inoculated soybean pastes, the
aroma active compounds of traditional fermented Chinese soybean
pastes need to be identified prior to the modification of production
process. The objective of this study was to compare the aroma
active compounds of volatile extractions from traditional fermented
and inoculated Chinese soybean pastes with SPME-GColfactotion
(GC-O) dilution analysis.
