Abstract

The quality characteristics of doenjang which contained Astragalus membranaceus water extracts were investigated in this study. The contents of moisture, crude protein, and crude fat were not significantly different in the doenjang which contained Astragalus membranaceus water extracts. The crude ash content was significantly higher in the doenjang which contained Astragalus membranaceus water extracts. The doenjang which contained Astragalus membranaceus water extracts showed higher a-value. Antioxidative activity was evaluated by using the thiobarbituric acid reaction products assay and peroxide value. Antioxidative activity and hydrogen donating activity were increased in doenjang which contained Astragalus membranaceus water extracts. Doenjang which contained Astragalus membranaceus water extracts showed no differences with traditional doenjang in sensory profiles of taste, color, flavor, and overall quality. These result showed the applicability and higher quality of doenjang which contained Astragalus membranaceus water extracts.
