In soy sauce preparation, a significant effect of salt concentration
on their physicochemical propertieswas clearly observed. Above all
things, some distinctive flavors were noticeably lower or not
detected by salt reduction, thereby, revealing a striking difference
between soy sauce with 8% salt and the other two salt concentrations.
Feng et al. (2014) reported that Chinese high-salt soy sauce
contains significantly higher levels of alcohols (especially ethanol
and 3-methyl-1-butanol) and esters (especially ethyl acetate),
whereas acids and aldehydes are lower than those of low-salt soy
