During the fermentation of Korean traditional soy sauce, pH and the reducing sugar content constituently decrease while total acidity increases (Lee et al., 2006a; Kim and Lee, 2008). As shown in
Table 1, the pH levels of soy sauce prepared with different salt concentrations (no inoculum) were 5.2e5.7, and S8 showed significantly lower pH compared to S11 and S14 (p < 0.05). Also, S8
had significantly higher total acidity (p < 0.05). Su et al. (2005) reported that decreasing the salt concentration leads to higher reducing sugars with lower pH, whereas our results revealed that total soluble solids and residual sugars were decreased by salt reduction (p < 0.05).
