To develop tofu enhanced nutrition, storage stability and bioactivity, the soft tofu supplemented with red ginseng extract was prepared. Then, quality characteristics including storage stability, physical and chemical property, antioxidative activity, and sensory evaluation were measured. The pH and acidity of control tofu without red ginseng extract were not different from those of tofu supplemented with red ginseng extract during storage. The aerobic bacteria in the control tofu were detected from 10 days of storage whereas the number of total aerobic bacteria was reduced or not detected in the tofu added red ginseng extract during storage. The lightness and redness of the tofu supplemented with red ginseng extract were lower than those of control, but yellowness was higher. The addition of red ginseng extract did not also affect the texture of tofu, and increased lipid peroxidation inhibition and DPPH radical scavenging activity. Although the soft tofu manufactured with red ginseng extract showed a lower sensory preference in supplementation over 0.20% due to color, there was not much difference found until 0.18% red ginseng extract addition.
