The antimutagenic effects of insoluble dietary fibers(IDF) extracted from some green-yellow vegetables(kale, carrot, spinach, broccoli and soybean sprout) and soybean by binding the carcinogens of MeIQ (2-amino-3,4- dimethyl-imidazo(4,5-f) quinoline) and Trp-P-2(3-amino-1-methyl-5H-pyrido[4,3-b] indole) in Salmonella tylhimirium TA100 and TA98 were studied. All of the insoluble dietary fiber samples which binded MeIQ exhibited high antimutagenic effects by removing the mutagen. Among the samples, IDFs from kale and soybean showed strong binding capacity fo the carcinogen and revealed about 90% of the antimutagenic activity. the IDF samples showed somewhat lower binding capacity to the Trp-p-2. The lignin which extracted from kale, soybean and carrot, and the cellulose strongly removed the mutagenicity of MeIQ by the binding. Among the samples, the level of lignin in kale revealed the highest(about 10%), and it seemed that the higher content of lignin in kale is one of the reasons to increase its antimutagenic effect.

Over the last decade, Sick Building Syndrome has become a significant social issue in Korea and many methods have been considered to maintain comfortable indoor air quality. To reduce toxic substances emitted from wood composite products, the source control is an efficient method through the reduction of formaldehyde content by using natural material-based adhesives for composite wood products production. Among alternative materials, soybean protein is considered an appropriate natural material to replace formaldehyde-based resin and many efforts have been made to produce new products, such as soap, shampoo, ink, resin, adhesive and textile through changing the chemical or physical properties of soybean. To process soybeans into these useful products, the beans are dehulled and the oil is removed by crushing at very high pressure or by solvent extraction. For use soybean as an adhesive, it is processed at temperatures below $70^{\circ}C$ to preserve the alkaline solubility of the proteins. In addition, soybean-based adhesive is undergone treatment process to improve mechanical properties using urea, urease inhibitor N-(n-butyl) thiophosphoric triamide and sodium dodecyl sulfate. The modified soybean-based adhesive exhibited sufficient mechanical properties to use as an adhesive for composite wood products. This paper is a review article to discuss the possibilities of soybean-based adhesive for environment-friendly furniture materials.

Antioxidant activity or green tea extracts (GTE) was evaluated in soybean oil (SBO), rice bran oil (RBO) and winterized rice bran oil (WRBO) stored at 63$^{\circ}C$ for 36 days. Lipid oxidation of the oils was determined using the active oxygen method (AOM), peroxide value (POV), change in unsaturated free fatty acid concentrations and by sensory evaluation. SBO had a higher concentration of the polyunsaturated fatty acids, linoleic and linolenic acid than RBO and WRBO. WRBO and RBO were more stable against lipid oxidation than SBO. Addition of GTE (200 ppm) to the stored oils, increased the induction period (IP) in AOM, reduced the increase in POV, and lessened the change in unsaturated fatty acids. Furthermore, GTE prevented the development of rancid flavors resulting from storage, all of which demonstrate the protective antioxidative activity of GTE. However, oil color became darker in the GTE treated oils. The antioxidant protection of GTE was most effective in RBO.

본 연구는 국내 농산부산물을 이용하여 in vitro 반추위 발효 특성을 조사하고 에너지 사료인 농후사료와 유사한 반추위 발효특성을 나타내는 농산부산물을 선정하여 최적배합수준을 통한 농후사료 대체 효과를 규명하기 위하여 수행하였다. 본 연구를 수행하기 위하여 국내에서 다량 생산되는 9점의 부산물(소맥피, 단백피, 제빵 부산물, 비지, 미강, 청치, 대두피, 주정박, 버섯배지)을 선발하였다. 1차 실험에서는 in vitro 배양을 통해 각각 원료사료의 시간대별(0, 3, 6, 12, 24, 48 h) 반추위 발효특성을 평가하였으며, 옥수수 및 대두박과 유사한 발효특성을 나타내는 원료사료 2종류를 선발 하였다. 최종적으로 선발된 2종류의 원료사료는 다른 원료사료와 혼합한 조합구를 만들어 in vitro 배양을 통한 옥수수와 대두박의 대체효과를 평가하였다. 실험설계는 옥수수와 대두박을 기본배합으로 하여, 알팔파, 티머시 건초 및 옥수수사일리지를 조사료로 사용하였다(T1). T2구는 대두박을 비지로 2.5% 대체, T3구는 옥수수를 청치로 15% 대체하였으며, T4구는 옥수수와 대두박을 청치와 비지로 각각 10 및 5% 대체하여 in vitro 반추위 발효특성을 평가하였다. 각 원료사료와 농산부산물의 in vitro 반추위 발효 특성을 조사한 결과, 옥수수 및 대두박과 유사한 발효특성을 나타내는 농산부산물로 청치와 비지를 선정하였다. 2차 실험에서는 pH의 경우, T4구에서 T1구와 비교하여 유의하게 낮았으며, 가스발생량은 T3 구에서 T1구와 비교하여 유의하게 높았다(p<0.05). 또한 건물 분해율은 3 및 24시간에 T4구에서 T1구와 비교하여 높았다(p<0.05). 결과적으로 농산부산물인 청치와 비지의 사용은 옥수수와 대두박을 일부 대체하기 위해 사용가능할 것으로 판단된다.

We profiled the health-promoting bioactive components in nine types of soybean seeds with different seed coat colors (yellow, green, brown, and black) and investigated the effects of different extraction solvents (methanol, ethanol, and water) on their antioxidant activities. The carotenoid and anthocyanin compositions varied greatly by seed color, and the phenolic acids, total phenol, and total flavonoid contents differed by genotype. The carotenoid content was relatively higher in soybean seeds with green and black seed coats than in those with a yellow seed coat while lutein was the most plentiful. The anthocyanin content was considerably higher in the soybean seed with the black seed coat. The results of the DPPH assay showed strong antioxidative activities in the methanol- and water-extracts compared to the ethanol-extract, irrespective of the seed coat colors. Moreover, the soybean seeds with the black seed coat exhibited the highest antioxidant activity among the samples, regardless of the extraction solvent used. Eighteen bioactive compounds were subjected to data-mining processes including principal component analysis and hierarchical clustering analysis. Multivariate analyses showed that brown and black seeds were distinct from the yellow and green seeds in terms of the levels of carotenoids and anthocyanins, respectively. These results help our understanding of the compositional differences in the bioactive components among soybean seeds of various colors, providing valuable information for future breeding programs that seek to enhance the levels of compounds with health benefits.

Purpose: Green soybeans (edamame) are now an economically important and popular food product in Japan. In order to shorten breeding time and to decide an optimal harvest time, we have been developing a dedicated NIRT spectrometer since 2004 for the determination of constituent content such as sucrose and free amino acids, which are two major contributors to the eating quality, in a single pod green soybean. Methods: The obtained models showed that the developed NIRT instrument had reasonable accuracy for the determination of these two components. Then we carried out the investigation into the change in two components during a few days storage using these models with changing time, variety/cultivar, packaging and temperature. Results: The result showed that the most affecting factor on decreasing both sucrose content and free amino acids was variety/cultivar. The time, packaging and temperature also affected significantly in most cases.

콩[Glycine max (L.) Merr. 2n=40]은 국내에서 벼 다음으로 많이 재배되고 있는 식량작물이며 성숙 콩 종실에는 3대 영양소외 페놀성 화합물, 이소플라본, 사포닌, 루테인 토코페롤, 피틴산, 루테인, 안토시아닌등 생리활성 물질이 다양하게 존재하지만 기능성과 가공 적성 및 품질을 저해시키는 성분들도 다수 존재한다. 성숙 콩 종실에서 품질, 기능성 및 가공 적성을 저하시키는 KTI 단백질이 없으면서 난소화성 올리고당인 stachyose 함량이 낮은 속 푸른 검정콩 유전자형을 육성하기 위하여 진행되었다. 3개의 모본으로 육종집단을 창성하여 검정종피, 녹색자엽 및 KTI 단백질이 없는 11개의 $F_2$ 종자를 얻었고 stachyose 함량이 낮은 2개의 계통을 선발하여 농업형질 평가를 통하여 검정 종피, 녹색자엽, stachyose 함량이 낮은 titirs2rs2 유전자형을 가진 계통을 선발하였다. 선발된 계통의 초장은 66 cm 정도였으며 백립중은 28.4 g으로 대립이었으며 종피색과 제색은 모두 검정색이었고 성숙 자엽색은 녹색이었다. 선발된 계통의 stachyose 함량은 일반품종(13.01-16.81 g/kg)보다 매우 낮은 2.59(g/kg)이었다. 본 연구를 통하여 선발된 계통은 Kunitz Trypsine Inhibitor (KTI) 단백질이 없으며 난소화성 올리고당인 stachyose 성분의 함량이 낮고 검정종피와 녹색자엽을 가진 기능성 고품질 유색콩 육성을 위한 중간모본으로 이용될 수 있을 것으로 사료되었다.

1. 콩나물을 25℃ 및 30℃에서 재배한 경우 17℃ 및 20℃로 재배한 경우에 비하여 발아일수에 따른 콩나물의 수율 및 콩나물의 특성들이 증가되지만 7일차 콩나물부터 부패가 시작하므로 콩나물의 재배에는 20℃가 적절한 것으로 판단되었다. 2. 재배토양에 따른 푸른콩나물의 생육시험은 밭 흙, 모래, 피트모스+펄라이트, 황토, 황토+활성탄에서 각각의 생육을 측정한 결과, 일반 모래땅에서 850g으로 생장량이 가장 좋았다. 3. BA 첨가에 따른 푸른콩나물의 몸통의 직경은 BA처리구에서 길어져서 무처리 1.4mm에 비해 BA 240, BA 80배에서는 2.0, 2.2mm로 증가하였고 BA 40배에서는 1.8mm로 다시 억제되는 경향을 보였다. 4. 푸른콩나물과 일반콩나물을 비교하면 탄수화물은 푸른콩나물의 섬유질이 0.9g으로 일반콩나물 0.6g보다 많았으나 당질은 0.81g으로 일반콩나물 2.9g보다 적었다. Vitamin은 푸른콩나물에서 Vitamin B가 일반콩나물에 비해서 2배 이상 높았으나 Vitamin C의 함량은 일반콩나물에 비해 적었다.
