This study evaluated the quality characteristics of dried noodles prepared with doenjang powder (0, 3, 6, 9%) in order to determine the most preferred noodle recipe. The proximate composition of the composite doenjang powder-wheat flours was as follows: calories 365 kcal, carbohydrates 79 g, saccharides 3 g, protein 10 g, fat 0.8 g, and sodium 65 mg. As the level of doenjang powder increased, the content of total amino acids increased; aspartic acid, glutamic acid, tyrosine, and lysine contents increased, in particular. Water-binding capacity decreased as the level of doenjang powder increased. When viscosity of composite doenjang powder-wheat flours was measured by amylography, gelatinization point increased as the level of doenjang powder increased. As the level of doenjang powder increased, L value decreased, whereas a and b values increased. Weight, water absorption, and volume of cooked noodles decreased, whereas turbidity of soup increased. For textural properties, hardness decreased, whereas springiness increased as the level of doenjang powder increased. For overall preference according to the results of sensory evaluation, noodles added with 3% doenjang powder were the most preferred. According to the results, addition of doenjang powder positively affects the overall sensory evaluation of dried noodle, and 3% is the optimal level for addition.

Changes in the Qualify Properties of Doenjang Prepared using the Powder or extracts of Paecilomyces japonica were investigated during fermentation at 20$^{\circ}C$. The moisture content was increased during fermentation but was not significantly different in all treatments. The pH of Doenjang with p. japonica was lower than the control group and decreased with the fermentation time. The amino nitrogen content increased gradually for up to 60 days and decreased slightly at 90 days. The L, a and b value decreased in proportion to the fermentation period and those of Doenjang with P. japonica powder were the lowest. From the results of the sensory evaluation, the color of the control group was similar to "yellow" but that of the Doenjang made from powder of P. japonica was close to "dark brown" and those of the Doenjang made from the P. japonica extract were darker than that of the control group. The texture was "glossy and smooth" in all cases and preference about the texture was high. The Doenjang with added P. japonica Powder had a saltier taste and the Doenjang with P. japonica Powder had the least sweet taste. In the flavor and overall Preference, the Doenjang with P. japonica powder was the lowest.

Change in Quality Properties of Doenjang Prepared with the Powder of Paecilomyces japonica and extract of P. japonica by different solvents were investigated during 90 days of fermentation at 20$^{\circ}C$. The moisture content was not significantly different, pH of Doenjang made with P. japonica was lower than control group and decreased continuously according to the fermentation time. Amino nitrogen continuously increased till 60 days and decreased slightly on 90 days. Value of L, a, b in Color decreased with proportion to fermentation period and L, a, b value of Doenjang made with P. japonica was lower and in Particular that of Doenjang made with P. japonica powder was lowest. From the result of sensory evaluation test, the color of control group was similar to “yellow”but that of Doenjang made with powder of P. japonica was close to“dark brown”and that of Doenjang made with extract of P. japonica was darker than that of control group and the preference of dark color was low. Texture was“glossy and smooth”in all and preference was high. In salty taste, Doenjang by P. japonica addition was stronger and Doenjang made with extract was stronger than that made with powder. Doenjang made with powder of P. japonica was weaker than other groups in sweet taste. In flavor and overall Preference, Doenjang made with P. japonica was scored lower slightly in than control group and Doenjang made with powder of P. japonica was the lowest in score.

본 연구는 세이지의 다양한 생리적 기능성과 우리 전통된장을 접목하여 허브를 첨가한 된장을 개발하고자 된장의 염도와 세이지분말 첨가량을 달리한 후 반응표면분석법으로 최적조건을 얻고자 관능특성을 조사하였다. 그 결과, 색은 1.20~2.70, 냄새는 1.60~3.20, 맛은 1.40~3.50, 조직감은 1.60~3.50, 전반적인 기호도는 1.60~3.05의 값을 나타내어 실험구의 조건에 따라 차이를 보였다. 이차회귀식에 의하여 형성된 반응표면 분석 결과 색, 냄새, 맛, 조직감 및 전반적인 기호도의 $R^{2}$가 0.11~0.41로 낮은 편이었으며, 5% 이내에서 유의성이 인정되지 않았다. 관능검사에서 가장 높게 평가된 것은 색은 염도 21.50%, 세이지분말 첨가량 3.10%일 때 2.91, 냄새는 염도 22.52%, 세이지분말 첨가량 3.68%일 때 3.21로, 맛은 염도 8.62%, 세이지분말 첨가량 4.46%일 때 2.87으로, 조직감은 염도 8.00%, 세이지분말 첨가량 6.06%일 때 2.88로, 전반적인 선호도는 염도 20.40%, 세이지분말 첨가량 2.66%를 첨가하였을 때 2.74로 나타났다. 한국인에게 익숙하지 않은 허브이지만, 세이지를 첨가한 된장이 일반된장 보다는 높은 점수로 평가되어 기능성 된장으로의 가능성을 확인할 수 있었다.

Suaeda asparagoides (Miq.) is a salt marsh plant, long been prescribed in traditional medicine for the treatment of hypertension and liver toxification in Asian countries. The powder of S. asparagoides was added at the ratio of 0, 5, and 10%, respectively, of grain-type Meju to manufacture Doenjang in brine according to the salt concentration (8 and 12%). After 24 weeks of fermentation, the Doenjang samples were determined to have an anti-inflammatory effect on RAW 264.7 cells. Evaluation of the anti-inflammatory effect of Doenjang added S. asparagoides powder extracted using 80% EtOH, was performed to study the inhibition of pro-inflammatory factors such as NF-κB (nuclar factor κB), NO (nitric oxide), TNF-α (tumor necrosis factor alpha), IL-6 (interleukin-6), iNOS (inducible nitric oxide synthase), and COX-2 (cyclooxygenase-2) in lipopolysaccharide (LPS)-induced RAW 264.7 cells. The results showed that the Doenjang extracts reduced the production of NO, IL-6, COX-2, and iNOS increased in the LPS-stimulated RAW cell without cytotoxicity. In the case of the NF-κB and TNF-α there was no significant difference between the control and samples. In conclusion, these results suggest that Doenjang added with the S. asparagoides powder acts as functional fermented food with anti-inflammation effect.

This study investigated the changes in the quality of doenjang (a fermented bean paste) with the addition of Sea tangle Saccharina japonica powder fermented by lactic acid bacteria (FSP). Doenjang was prepared without or with FSP and with various amounts of doenjang (0, 0.25, 0.5, 1 and 3% by volume), and fermented at $25^{\circ}C$ for 12 weeks. After 12 weeks, the antioxidant activity, microbiological characteristics, and physicochemical parameters were examined. We detected no significant differences in the color profiles. However, following the addition of FSP to doenjang, the amino nitrogen content and antioxidant properties were enhanced. Furthermore, the FSP-doenjang contained higher levels of ${\gamma}$-aminobutyric acid (297.55-300.03 mg/100 g), a biofunctional ingredient. These results suggest the potential for developing a traditional Korean fermented food with enhanced antioxidant activity and ${\gamma}$-aminobutyric acid content using FSP.

생리활성이 우수하다고 알려진 된장의 소비확대를 위하여 시판 된장을 이스트 발효 식빵 제조에 이용하고자 식빵 배합비에 7종(A; 재래식 된장, B∼E; 시판 개량식 된장, F;시판 Miso type 된장, G; Japanese Miso)의 동결건조한 된장분말을 2.5∼10.0% 첨가하여 발효력과 오븐팽창력을 관찰하고 빵품질을 물리적 측면에서 조사하였다. 사용된 시판된장 7종의 이화학적 특성치로는 일반성분을 비롯하여 아미노태질소, 총산도, 환원당, 유리당, 염도, 유기산 함량 및 단백질분산지수(PDI)를 제시하였다. 빵 배합비에 된장분말 5.0% 이하의 첨가는 오븐팽창력의 현저한 증가로 모든 된장 첨가식빵 부피가 증가하여 무첨가구에 비하여 최대 13%까지 높게 나타났다. 또한 된장첨가로 기계적 조직감 측정치인 경도(hardness), 검성 (gumminess), 씹힘성(chewiness) 등이 감소하여 전반적으로 부드러워졌고, 빵의 색은 어두워졌다. 그러므로 식빵제조에 시판된장의 사용은 빵의 물리적 품질 향상에 매우 긍정적인 효과를 가져왔다. 이때 식빵의 부피나 조직감은 된장 종류나 첨가수준에 의하여 독립적으로 영향을 받을 뿐만 아니라 이들 처리조합의 상호작용에 의하여도 크게 영향을 받는 것으로 나타났다.

된장의 고유한 향미에는 영향을 미치지 않으면서 기능성이 향상된 유백피 된장 개발을 위해 유백피 된장의 물리화학적 분석을 통해 다음과 같은 결과를 얻었다. 유백피 된장은 일반 된장에 비해 pH와 염도가 낮으며, 관능검사에서는 단맛이 강하고 짠맛은 약하나 구수한 맛을 나타냄으로써 일반 된장에 비해 전체적으로 높은 기호 도를 확인하였다. 항산화 작용의 지표인 DPPH 소거 활성측정 결과 $IC_{50}$값이 일반된장($155.67{\mu}g/mL$)에 비해 훨씬 높은 항산화 활성($29.16{\mu}g/mL$)을 확인할 수 있었다. 연구 결과 기능성과 기호도 고려할 때 유백피가 1% 첨가된 된장이 가장 적합할 것으로 판단된다.
