This study was carried out to investigate the effects of addition ratio(0, 5, 10 and 20%) of various minor ingredients(prosomillet, glutinous barley, oat, wheat, yellow and black soybean, safflower seed, chocolate etc.) on mechanical and sensory characteristics of Sulgiduk. In mechanical evaluation, hardness, cohesiveness and gumminess were increased with increasing the content of prosomillet, glutinous barley, oat and wheat to be added, and did not show any relationship the content of them to be added on yellow and black soybean, safflower seed and chocolate. In sensory evaluation, quality characteristics of Sulgiduk added with prosomillet, oat, yellow and black soybean and chocolate with 5∼10%, respectively was better than those of Sulgiduk without the minor ingredients. Change of hardness on Sulgiduk added with oat, yellow soybean, black soybean and chocolate was lower than those of Sulgiduk without them during storage of room temperature.

Background : The fruit of Lycii fructus (Gugija) has beeen used as a tonic medicine and a long-term healthy food without side effect in Asia. An increase in the demand for natural healthy food, Gugija has been thought as a source of healthy foods, and then the extracts of dried Gugija have been frequently used as food ingredients. But, its extracts with Gugija alone has a slightly bad taste. Physiological characteristics of Gugija extracts were investigated by adding white ginseng (WG) and red ginseng (RG) to enhance taste. Methods and Results : Gugija extract were prepared by adding 0, 20, 40, 60, 80 and 100% of ginseng (WG and RG) to the weight of Gugija, respectively. Antioxidant activities of Gugija extracts were investigated DPPH and ABTS radical scavenging activity, SOD-like activity, FRAP, activity. As the amount of WG added increased, DPPH, ABTS radical scavenging activity, and FRAP activity of Gugija extract decreased. On the other hand, the physiological activity of Gugija extract increased with increasing amount of RG. The SOD-like activity of Gugija extract added up to 60% of WG and to 40% of RG was continuously lowered, in the addition amount thereafter, the activity increased as the addition amount increased. In components, As the amount of WG and RG added increased, the ginsenosides content of Gugija extract increased, the content of ginsenosides was higher in extract added RG than WG, but betaine and total flavonoid content decreased. Conclusion : From the above results, we may suggest that Gugija extracts by adding RG increased the antioxidant activities, SOD-like activity, and the preference degree.

국산 콩 재배를 장려하고 메주 및 된장가공용으로 적합한 우수 콩품종을 선발하고자 충남도내에서 주로 재배되고 있는 대원, 소담, 진품 및 황금 콩을 이용하여 메주 및 된장을 제조한 후 품종간 품질의 특성을 조사하였다. 원료 콩들의 일반성분 중 조지방은 16.89∼19.31%, 조단백질은 26.7∼30.5%,이었고 품종별 총 유리당함량은 4.99∼5.26%로 주된 유리당은 stachyose으로서 2.59∼3.51%를 함유하고 있었고 그 다음은 raffinose와 sucrose순이었다. 메주의 조지방은 16.2∼21.0%로 황금콩이, 조단백질은 32.2∼36.4%로 대원과 소담콩이, 가용성무질소물은 23.5∼26.62%로 진품콩이 각각 함량이 높았으며 아미노태 질소함량은 266∼ 371 ㎎%로 대원콩이 가장 높았다. 메주의 총 유리당은 2.10∼2.66%로 주된 유리당은 glucose이었으며 대원콩이 유리당함량이 높았다. 메주덩어리의 색도를 본 결과 황금콩이 밝기가 가장 감소하였으며 적색도는 대원콩과 황금콩이 높았고 황색도는 소담콩이 가장 높게 나타났다. 또 메주를 분쇄하여 메주분으로 조사한 결과 소담콩이 밝기값이 가장 높았고 적색도가 가장 낮았으며 황색도는 황금콩이 가장 높았다. 발효된장의 조지방은 7.90∼9.71%로 진품콩이, 조단백은 9.67∼13.50%로 대원콩이, formol태 질소함량은 2739∼3825㎎%로 소담콩이, 조사포닌 함량은 6.88∼8.36%로 대원콩이 각각 함량이 가장 높았으며 총유리당 함량은 1.88∼2.22%으로 황금콩이 가장 높았으며 된장의 주된 유리당은 fructose와 glucose이었다. 된장제품의 색도 중 밝기와 황색도는 소담콩이 가장 높았으며 적색도는 황금콩이 가장 높았다. 된장제품의 관능검사결과 소담콩이 색깔면에서는 우수하였으나 맛, 질감 및 전반적인 기호도를 볼 때 황금콩이 가장 좋은 것으로 평가되었다. In order to selection of the suitable soybean varieties, the quality characteristics of meju and doenjang on 4 domestic soybean cultivars(Daeweon, Sodam, Jinpeum and Hwangkeum) were evaluated. Crude protein and lipid content was 26.7∼30.5% and 16.89∼19.31%. The content of total free sugar among 4 soybean cultivars were 4.99∼5.26% and composed mainly stachyose(2.59∼3.51%), raffinose and sucrose. The content of total free sugar of meju were the highest in Jinpeum among 2.10∼2.66% and composed mainly glucose. The lightness of meju lump in Hwangkeum was larger decrease than the others, the redness were higher in Daeweon and Hwangkeum, the yellowness was the highest in Sodam. The lightness of meju powder was the highest in Sodam, the redness was the lowest in Sodam, the yellowness was the highest in Hwangkeum. The chemical composition of doenjang were that : was the highest in Jinpeum among the 7.90∼9.71% crude lipid, in Daeweon among 9.67∼13.50% crude protein, in Sodam among 2739∼3825 ㎎% Fromol nitrogen and in Daeweon among 6.88∼8.36% crude saponin, respectively. The content of total free sugar of doenjang were the highest in Hwangkeum among 1.88∼2.22% and composed mainly fructose and glucose. The lightness and yellowness of doenjang was the highest in Sodam, the redness was the highest in Hwangkeum. Doenjang by Hwangkeum had good score for taste, texture and overall quality in sensory evaluation.

In order to develop of health-oriented convenience foods for rice consumption, functional Misutkaru drink was made by adding several medicinal herbs extracts to fundamental Misutkaru based cereal powder(rice, barley and soybean). Fundamental Misutkaru drink was prepared with the ratio of cereal mixed rice(5g), barley(5g) and soybean(5g) on water (100 mL) and several medicinal herbs extracts. Liriopis Tuber(50%), Omija(15%), Ginseng(10%) and Jujube(25%) were mixed to fundamental Misutkaru as functional Misutkaru. And then it was extracted to added water of 10times during 36hrs at 75℃. For instant Misutkaru drink of health-oriented convenience foods, mixture of them was made with fundamental Misutkaru drink(80%), extract of several medicinal herbs(20%), and it's sensory score was high. Autoclaved functional Misutkaru drink for long storage period was changed rheological type badly. Overall acceptability and storage period of nonautoclaved functional Misutkaru drink to added extract of several medicinal herbs was higher than fundamental Misutkaru drink.

Background : Korea ginseng root has been traditionally used as a tonic as it is stated to have the capacity to normalize body functions and strengthen systems that are caused by various stresses. But, white ginseng (WG) has lower antioxidant activity than other medicinal crops. Omija (Schisandra chinensis Baillon) has various physiological functionalities such as anti-cancer, anti-inflammatory, and antioxidant activities, which have the effective components of Omija are lignans (schizandrins and gomisins), and this components were contented mostly in seed part on Omija. Physiological characteristics of WG extracts were investigated by adding Omija to enhance functionality. Methods and Results : WG extract were prepared by adding 0, 20, 40, 60, 80 and 100% of Omija to the weight of WG. Physiological characteristics of WG extracts were investigated DPPH radical scavenging activity, FRAP, and nitrite scavenging activity. As the amount of Omija added increased, DPPH radical scavenging activity of WG extract increased proportionally. IC50 of 10 times water extracts were 0.455, 0.028 and 0.041 ml/ml on WG (100WG), WG added 50% Omija (50OM50WG), and Omija (100OM0WG), respectively. On the other hand, FRAP of extracts decreased slightly with increasing amount of Omija. Nitrite scavenging activity of Omija extract were significantly more active than WG extract, exhibited to 88.89% and 72.65% on WG extract added with 40% Omija (40OM60WG) and non added (100WG), respectively, pH 1.2. and then, to 33.45% and 1.38% with 40OM60WG and 100WG extract, respectively. Conclusion : From the above results, we may suggest that WG extracts by adding Omija increased the DPPH radical scavenging activity, nitrite scavenging activity and the preference degree on taste.
