Changes in chemical composition, viscosity and color during fermentation of improved Kochoojang from four starch sources (wheat, barley, rice and glutinous rice) were examined. Analyses included measurements of moisture, reducing sugars, amino nitrogen, pH, total acidity, viscosity, color and sensory panel scores for viscosity, color, odor and taste. Changes in chemical composition were similar for all Kochoojang products. Decrease in viscosity was greatest during the first 10 days of fermentation. Hunter tristimulus values decreased gradually during fermentation, and total color difference after 60 days was greatest for rice flour Kochoojang. Sensory evaluation showed that the viscosity of rice flour Kochoojang was less desirable than that of the others. However, no significant differences were found in color, odor and taste of all Kochoojang products. A high negative correlation was observed between Hunter a value and visual preference.
