This study was conducted to improve the sensory acceptability of modified Kochujang added with Tofu powder(25%, 50%, 75%, 100%) instead of Meju powder. These Kochujang samples were fermented for 45 days and examined in physicochemical properties and sensory characteristics. The result was as follows. Moisture content of the control was higher than that of the other Tofu powder Kochujang samples, which lasted for 30 days of storage. Moisture contents of all samples were increased by storage time. The pH of Kochujang added with Tofu powder was higher than that of the control. In general, pH values were decreased by storage time. Acidity decreased with Tofu powder increased while it generally increased with more storage time. In the lightness(L value), redness(a value) and yellowness(b value), control Kochujang was the lowest. There were no significant differences in the reducing sugar contents except 45 days. In sensory evaluation, color of Kochujang was evaluated light and off-flavor got weaker with Tofu powder increased. In the sensory attributes of odor, taste, overall acceptability, Tofu powder added Kochujang had high scores than the control, and especially 100% TP Kochujang had the best score.

The contents of organic acids in traditional and modified fermented foods were compared, and propionic acid produced during fermentation was investigated. Organic acids in traditional and modified soy sauces were lactic acid, acetic acid, citric acid, formic acid, succinic acid and oxalic acid while propionic acid was found in traditional soy sauces only. Similarly, lactic acid, acetic acid, citric acid, oxalic acid, formic acid, succinic acid and propionic acid were found in traditional and modified soy paste. The organic acids in traditional and modified kochujang were citric acid, acetic acid, formic acid, lactic acid, malic acid, oxalic acid and succinic acid while propionic acid was not found in modified kochujang. The major organic acid in persimmon and commercial (fermented) vinegars was acetic acid. Propionic acid was uniquely found in persimmon vinegars. Also, content of tannic acid in persimmon vinegars was 366.9 ∼ 909.8 mg%.

Prior to 1970, it was known that Korean had our own red pepper named as Kochu and we used Kochu in preparing kimchi and kochujang. However, after Professor Lee insisted that Korean red pepper (Kochu) was transferred from Japan during the Seven Years War (Imjinwaeran(壬辰倭亂)), Japanese Invasion of Korea in 1592${\sim}$1598), it has been generally accepted without any criticisms. But many old literatures have shown that Korean Kochu already existed in Korea before the war. For example, the books, Kukubkanibang ((救急簡易方) published in 1489) and Hunmongjahoi ((訓蒙字會) published in 1527), demonstrated that Kochu was cultivated as food substances or medicinal purposes. In another old literature (1460), Siklyochanyo(食療撰要), kochujang was used as an uncomfort-stomach stabilizer. In addition, Korean red pepper was genetically different from South-Mid America's red pepper called as Aji. It has been also insisted by Professor Lee that Aji was transferred to Europe by Columbus in 1492 and then to Korea by Japanese Army in order to kill Korean during the war, and the Aji was modified to Korean Kochu. In conclusion, in Korea our own Kochu was cultivated and used in the Korean native fermented foods such as kimchi and kochujang.

Dietary intakes and sources of vitamin B$_{6}$ in 72 healthy Korean elderly subjects (29 men,43 women, $\geq$57 years of age) living in the Seoul area were estimated using a modified Korean vitamin B$_{6}$ database. The dietary vitamin B$_{6}$ intake and food sources were estimated by the three day recall method with the help of a trained interviewer. Food portion sizes were estimated using standard household measures and published average portion sizes. The average daily vitamin B$_{6}$ intake was 2.06$\pm$0.46 mg/d in elderly men, and 1.94$\pm$ 0.47 mg/d in elderly women. Less than 5% of elderly men and 15% of elderly women consumed less than the Korean Recommended Dietary Allowance (RDA) of vitamin B$_{6}$. The average ratios of vitamin Be intake to daily protein intake were 0.03 $\pm$ 0.01 mg/g in both elderly men and women. The intake of vitamin B$_{6}$ was significantly (p <0.01 ∼ p<0.001) and positively correlated to intakes of all other nutrients in elderly women, but was not significantly correlated to intakes of several nutrients in elderly men. Foods from animal and plant sources provided 24% and 76%, respectively, of the total vitamin B$_{6}$. Major dietary sources of vitamin B$_{6}$ in Korean elderly were rice, soybean sprout, kimchi, pork, beef, potatoes, garlic, onion, anchovy and kochujang. The major sources accounted for most of the vitamin B$_{6}$ intake with the top 20 foods providing nearly 75∼76% of the total vitamin B$_{6}$ in Korean elderly./ in Korean elderly.
