        This study was conducted to investigate the antioxidant activity of Kochujang following the addition of Omija (Schizandra chinensis Baillon) by-product extract powder. This study specifically investigated the total levels of phenolics and flavonoids, the activities of DPPH and ABTS radical scavenging, and FRAP (ferric reducing antioxidant power). Our results showed that the total phenolic and flavonoid contents of unmodified Kochujang were 4.06 mg TAE/g and 2.87 mg TAE/g, respectively, and that the total phenolic and flavonoid contents of Kochujang with added Omija by-product extract powder were 3.89~5.19 mg TAE/g and 3.11~5.35 mg TAE/g, respectively. As more Omija by-product extract powder was added, the more the total levels of phenolic compounds and flavonoids increased. This study found that DPPH radical scavenging activity in unmodified Kochujang was 25.8% and that in Kochujang with added Omija by-product extract powder was 27.1~39.7% each. These results indicate that Omija by-product extract powder has possibility not only in Kochujang products but also as a functional food with antioxidant activity characteristics. These results also indicate that adding Omija by-product extract powder to Kochujang had significant effects on overall acceptability. Thus, the addition of 5 or 10% of Omija by-product extract powder is desirable for making Kochujang.

        The antiobesity effect of commercial kochujang and fermented wheat grains in Sprague-Dawley (SD) rats was studied. The experiment was consisted of 6 groups. Normal, high fat diet (HFD), HFD+raw wheat grains, HFD+first fermented wheat grains (FFWG, with Aspergillus oryzae) HFD+final fermented wheat grains (FiFWG, fermented more for 30~40 days), and HFD+ commercial kochujang. The results showed that final body weight, weight gain, food efficiency ratio, and adipose tissue weight were markedly decreased by the commercial kochujang and the fermented wheat grains, whereas non-fermented raw wheat grains had no such effect. Lipid contents such as total lipid, total triglyceride and total cholesterol decreased in the serum and organs of liver and adipose tissues by the commercial kochujang and the fermented wheat grains as well. These results also indicated that fermented wheat grains exhibited more suppressive effects on high fat induced-obesity than raw wheat grains. Increased fermentation time and adding the red pepper powder resulted in increased the anti-obesity effect. Especially, commercial kochujang showed higher antiobestic effects than fermented wheat grains. These in vivo findings suggested that well-fermented end products of the wheat grains and red pepper powder in kochujang could be useful in the prevention of obesity.

        The physicochemical and sensory properties of barley Kochujang added with germinated barley powder were periodically examined during storage at 20 for 40 days. The pH of barley Kochujang added with germinated barley powder increased gradually according to the level of added germinated barley powder, whereas it decreased gradually during storage. On the other hand, acidity showed the opposite relationship with addition level. Salinity of the samples decreased gradually according to the amount of added germinated barley powder. Amino nitrogen content of barley Kochujang increased gradually according to the amount of added germinated barley powder, whereas it increased gradually during storage. L-, a-, and b-values of samples increased gradually according to the amount of added germinated barley powder, whereas they decreased gradually during storage. As a result of the sensory evaluation, barley Kochujang added with 5% germinated barley powder was found to be superior in taste, viscosity, and overall preference. Sensory evaluation revealed that addition of 5% germinated barley powder was optimum for improving Kochujang quality.

        In this study, we aimed to increase the utilization of non-commercializable peach fruits collected during harvesting and distribution and to promote the transition of a high value-added industry. After producing pastes from the flesh of different peach varieties, we used these pastes as ingredients in the production of Kochujang. We then performed a comparative analysis on the quality characteristics of the peach-added Kochujang and commercially available Kochujang products. Peach-added Kochujang exhibited a lower pH and reduced sugar, salinity, reducing sugar, ash, and calorie content than those of commercially available Kochujang products. However, the Kochujang had slightly higher pH and moisture content than commercially available products due to high organic acid and moisture contents of peach flesh. In terms of content of inorganic elements, commercial Kochujang products exhibited higher sodium and magnesium content, whereas peach-added Kochujang had higher potassium content. In particular, the lower sodium and higher potassium content of peach-added Kochujang indicates that this product could be used as a functional food to prevent various diseases caused by excessive sodium intake among Koreans. After comparing the products in terms of phenol and flavonoid content, we concluded that ethanol extracts of peach-added Kochujang showed higher phenol content than those of the commercially available Kochujang products. In contrast, the distilled water extracts of peach Kochujang showed higher DPPH free radical scavenging activity than that of commercially available Kochujang products.

        Kochujang was prepared by replacement of rice (25%, control) with pumpkin or purple sweet potato by 0. 5, 10, and 15% (total addition ratio of rice and sweet potato=25% of sample). Effects of the addition of sweet potato on physiochemical properties of fermented Kochujang were investigated. Viable cells of yeast decreased in the sweet potato-added Kochujang at the later stage of fermentation, while there was no significant difference in the number of bacteria among the test groups. As the addition ratio sweet potato increased, α-amylase activity increased while protease activity decreased. Hunter L, a, and b values of Kochujang prepared with purple sweet potato were lower than those with pumpkin sweet potato. Changes in ΔE value was greater in Kochujang prepared with pumpkin sweet potato than that with purple sweet potato. Oxidation-reduction potential and water activity were higher in sweet potato-Kochujang than control, but reducing sugar content was higher in control. Alcohol and amino-type nitrogen contents were higher in Kochujang prepared with pumpkin sweet potato than that with purple sweet potato, but it was not significant. Overall sensory acceptability was highest in Kochujang prepared with 10% of purple sweet potato while that with 15% pumpkin sweet potato was the least preferred.

        본 연구에서 고추장 제조시 발효가 항돌연변이 효과와 in vitro 항암효과에 미치는 영향을 확인하기 위하여 고추장 제조 재료인 원료 밀, 1차발효밀, 2차발효밀, 최종발효밀, 고춧가루와 최종발효밀로 제조된 고추장의 Sal. Typhimurium TA100을 이용한 Ames test를 실시하여 MNNG에 대한 항돌연변이 효과를 살펴보았으며, HT-29 인체 대장암세포와 AGS 인체 위암세포의 성장 억제효과를 살펴보았다. 실험한 결과 원료 밀보다 1차발효밀, 2차발효밀보다 최종발효밀이 발효진행에 따라 점차 증진된 항돌연변이 효과와 in vitro 항암효과가 나타났으며 최종발효밀과 고춧가루로 제조된 고추장이 가장 높았다. 15, 30일 발효시킨 고추장이 발효되지 않은 고추장보다 더 높은 항암효과가 나타났다. 따라서 발효과정(기간)이 고추장의 항돌연변이 효과와 항암효과에 중요하게 관련되어 있다고 할 수 있으며 고추장의 주재료인 고춧가루의 capsaicin, 비타민C와 β-carotene 등의 작용만이 아닌 밀에서 온 발효 숙성 중에 많이 증식된 미생물 그리고 발효에 의한 생성된 다른 활성물질이 항돌연변이와 항암 효과에 관련되어 있다고 하겠다.
