This study was carried out in order to analyze the changes in general compounds and sugars of traditional Korean soy sauce with varying Meju concentrations (Meju-water ratios of 1 : 4 and 1.3 : 4) and ripening periods (up to 2 years). Along with ripening period, pH decreased and titratable acidity, total acidity and crude protein contents increased, which were higher in 1.3 : 4 than in 1.4. Buffering power increased significantly with increasing ripening period. Crude fat content was higher in 1.3 : 4 than 1 : 4. Moisture content decreased and pure extract content increased significantly with increasing ripening period, which was high in 1.3 : 4. Salt contents increased with increasing ripening period, but decreasd in soy sauce ripened for 2 years. As the result of sugar analysis, reducing sugar showed slow increase with increasing ripening period. Among detected free sugars, galactose was present in the highest concentration and the rest were in the sequence of glucose, fructose. Total free sugar content was highest in soy sauce ripened for 150days in 1 : 4 and 210 days in 1.3 : 4.
