This study was conducted to produce the high quality of chunggugjang. The taste compounds of chunggugjang produced with Bacillus subtilis DC-2, pigment producing bacterium, were analysed, and palatability of chunggugjang was compared to that of commercial chunggugjang. Among the volatile organic acids, the contentof acetic acid was contained more than any other volatile organic acid. The major nonvolatile organic acid was lactic acid, followed by oxalic acid and citric acid. Tartaric acid was not detected. In case of free sugars, raffinose was sharply decreased between 72 and 96 hours after fermentation. Free amino acid was increased to 20 folds at 48 hours after fermentation compared to that of stemed soybean. As a result of sensory test, it was founded that the chunggujang fermented by Bacillus subtilis DC-2 was suitable to produce for commercial purpose.
