Abstract
The objective of this study was to obtain basic data on Korean traditional meju collected in 17 regions of Korea, to define and control meju quality. The moisture, crude fat, crude protein, and amino nitrogen contents of meju were 9.83-36.24%(w/w), 17.46-28.74%(w/w), 42.00-45.54%(w/w), and 223.65-1137.68 mg%, respectively. Meju was the enzyme source which made the soy sauce and doenjang. The $\alpha$-amylase, $\beta$-amylase, and protease levels were 130.32-1254.45, 30.07-167.88 and 72.53-340.04 units, respectively. Regional enzyme activities differed widely. Bacterial levels were $4.8{\times}10^7-2.6{\times}10^{10}cfu/g$, and molds and yeasts were at $4.3{\times}10^4-7.9{\times}10^6cfu/g$.
