Abstract
Bacterial-koji was prepared by using B. subtilis DJI and Doenjang was prepared by using the bacterial-koji and purified salt or solar salt at 12% (w/v) concentration. Characteristics of the Doenjangs were examined after 2 months of aging. Moisture contents of the purified salt-Doenjang was decreased from 51.55% to 45.38% whereas that of the solar salt-Doenjang was decreased from 51.88% to 47.90%. Acidities of the Doenjangs were gradually increased. Hunter's L (lightness) color values of the Doenjangs were decreased. Browning reaction rate of purified salt-Doenjang was faster than solar salt-Doenjang. The content of free amino acids in solar salt-Doenjang was higher than those in purified salt-Doenjang. The major free amino acids of the Doenjang were glutamic acid (252.34 mg%~284.07 mg%), phenylalanine (184.72 mg%~224.71 mg%), leucine, tyrosine and valine.
