  • This study investigated the quality characteristics of black soybean sediments to diversify the availability of soybean. The cooking method selected for black soybean sediment preparation was a pressure cooking process without soaking, considering the isoflavone content. The black soybean sediments were prepared by the addition of 0, 10, 30, 50 and 100% (w/w) black soybean. When 0% to 100% black soybean was added to the black soybean sediments, the moisture and crude protein contents increased from 53.17% to 54.41% and from 12.07% to 21.68%, respectively. The total isoflavone content of the black soybean sediments was increased from 2.69 ㎍/g to 696.09 ㎍/g, respectively, by the addition of black soybean. The anthocyanin content of the black soybean sediments ranged from 279.29 ㎍/g to 387.8 ㎍/g by the addition of black soybean. The total polyphenol content and the total flavonoid content of the black soybean sediments range from 1.72 mg/g to 2.00 mg/g and 0.89 mg/g to 0.92 mg/g, respectively, by the addition of black soybean. Given the isoflavones, total polyphenol, and anthocyanin content of the black soybean sediments, it is appropriate that the ratio of added black soybeans is at least 50% after the pressure-cooking process, regardless of soaking.

  • In order to determine the most effective ratio of black soybean powder as an ingredient in cake, black soybean power was added at ratio of 10, 20, 30, and 40% versus wheat flour set as 0(control). Black soybean powder consisted of moisture(8.44%), crude protein(31.34%), crude fat(6.64%), crude ash(3.88%) and carbohydrates(49.70%). The specific gravity, spreadability, and baking loss increased according to the amount of black soybean powder, although specific volume decreased. The chromaticity 'L' and 'b' values of sponge cake with black soybean powder showed an reducing trend while the 'a' value displayed an increasing trend with an increase in black soybean powder. The texture properties of sponge cake with added black soybean powder showed an increasing trend in hardness and stiffness when the cake contained more black soybean powder. The sensory test for sponge cake with added black soybean powder showed high preference for 20% added black soybean powder to sponge cake.

  • Baked black soybean has great nutritional value, so it is a great potential ingredient in cake. To find an acceptable ingredient ratio, baked black soybean powder was to wheat flour in different experimental groups. The control was pure wheat flour, and the experimental groups had 0 (control), 10%, 20%, 30%, and 40% baked black soybean powder added. The baked black soybean powder consists of moisture (4.88%), crude protein (34.46%), crude fat (11.35%), crude ash (4.84%), and carbohydrates (44.47%). The specific gravity, spreadability, and baking loss increased with an increase in the amount of baked black soybean powder, but specific volume decreased. The 'L' and 'b' chromaticity values of a sponge cake decrease with increased amounts of added baked black soybean powder. The texture becomes more hard and stuff with added baked black soybean powder, but springiness decreases. A sensory test found the best experimental group to be that of 20% powder added.

  • In this study, the effects of processed small black soybeans on the intestinal morphological characteristics of rats were examined. Adult male rats were fed diets containing raw, cooked, or acidified small black soybean powders for 4 weeks. The total short chain fatty acid (SCFA) level was significantly higher in the acidified small black soybean supplemented group than in the raw and cooked soybean diet groups. The major SCFAs found in the experimental groups were acetate, followed by propionate and butyrate. The duodenal villus height and colonic mucosal thickness were also significantly higher in the acidified small black soybean supplemented group than in the raw and cooked soybean diet groups. The acidified small black soybean supplemented group showed the densest colonic mucosa by staining with alcian blue (AB), as compared to the raw and cooked soybean diet groups. The acidified small black soybean supplemented group exhibited strongly stained $CD4^+$ in the mucosal lamina propria, while cooked and acidified diet groups were more strongly stained $CD8^+$ in the submucosal lamina propria than the raw diet group. These results suggest that acidified small black soybeans may help improve intestinal function.

  • The effects of black soybena extracts on enzymes activies of rat were evaluated in present study. Eighty-four male Sprague-Dawley rats weighing 100$\pm$10g were divided into twelve groups which consisted of black soybean extract, Pb and Cd solution, and black soybean extract plus Pb or Cd soln groups. The weight gain was increased in black soybean extracts and Pb soln solution group but decreased in Cd soln solution group. The results obtained form the experiment were as follows: Glutamate pyruvate trasaminase (GPT) and glutamate oxaloacetate oxaloacetate transaminase (GOT) activities were not significantly different among experimental groups. The lactate dehydrogenase (LDH) activities of black soybean extract administered groups were decreased than those of Pb and Cd solution group. Black soybean group increased cholinesterase (ChEase) activity as compared to administration of Pb and Cd soln group.

  • The effects of raw and processed small black soybean powders on dietary fiber content and gastrointestinal function in rats were investigated. The crude oil, protein, and ash contents of raw small black soybean powder were not significantly different from those of processed small black soybean powders. The germination process increased soluble and insoluble dietary fiber contents significantly, as compared to raw small black soybean powder. The germinated small black soybean powder diet led to a significantly different food intake than the basal diet in both normal and loperamide-induced constipated rats. The body weight gains of the experimental groups, however, were not significantly different from that of the basal diet groups for both the normal and loperamide-induced rats. The gastrointestinal transit times and fecal weights for normal and loperamide-induced rats consuming the processed small black soybean powder diet were significantly different from those on a basal diet. These results suggest that the processes of cooking and germinating the small black soybean might contribute to acceleration of fecal excretion in both experimental normal and constipation model rats.

  • Lipoxygenase and Kunitz trypsin inhibitor protein of mature soybean [Glycine max (L.) Merr.] seed are main anti-nutritional factors in soybean seed. A new soybean cultivar, "Gaechuck#1" with the traits of black seed coat, green cotyledon, lipoxygenase2,3 and Kunitz trypsin inhibitor protein free was developed. It was selected from the population derived the cross of "Gyeongsang#1" and C242. Plants of "Gaechuck#1" have a determinate growth habit with purple flowers, brown pubescence, black seed coat, black hilum, oval leaflet shape and brown pods at maturity. Seed protein and oil content on dry weight basis have averaged 39.1% and 16.2%, respectively. It has shown resistant reaction to soybean necrosis, soybean mosaic virus, Cercospora leaf spot and blight, black root rot, pod and stem blight, and soybean pod borer. "Gaechuck#1" matured on 5-10 October with a plant height of 50 cm. The 100-seed weight of "Gaechuck#1" was 23.2g. Yield of "Gaechuck#1" was averaged 2.2 ton/ha from 2005 to 2007.

  • It has been believed that supplementation of human diets with soybean products markedly reduces human cancer mortality rates. Specifically the black colored soybean has been considered as having a medicinal effect since ancient times in Korea. Six genotypes of black colored soybean and a normal variety were investigated for their biological effect. While the isoflavone content of black colored soybean was higher than the normal soybean, saponin content of the seeds was not different among varieties. In the case of antioxidant activity, black colored soybean showed over 3 times increase in the active effect than the control variety. When feeding soybean extract, a general change of alcohol resolving effect, such as alcohol dehydrogenase activity, was observed in the blood and liver of rats.

  • For the purpose of developing a functional yogurt, a new type of yogurt was prepared. To manufacture this new yogurt, 12% skim milk was added to the hot water extract of black soybeans. The yogurt was then evaluated for its acid production(pH and titratable acidity), number of viable cells, viscosity, quality-retention properties, and sensory properties. The titratable acidity of the yogurt with the added 5% black soybean hot-water extract was higher(2.07%) than that of the yogurt without the added extract(1.80%). The viscosity of the yogurt made by adding 5% black soybean hot-water extract was higher(5,040 cps) than that of the yogurt made with only skim milk(2,740 cps). Lactic acid bacteria propagation was stimulated by the addition of the 5% black soybean hot-water extract. When the yogurt prepared with the black soybean hot-water extract was kept at $7^{\circ}C$ for 14 days, its quality-retention was comparatively good. Finally the overall sensory score of the yogurt made with the added 5% black soybean hot-water extract was slightly lower than that of the yogurt made with only skim milk.

  • Soybean curds were prepared by adding different levels (20, 40, and 60%) of small black soybean, and the quality characteristics of the soybean curds were investigated. The yield of soybean curd increased slightly with the increment of the levels of small black soybean, whereas L value (lightness) and b value (yellowness) decreased. Analysis of textural properties demonstrated that the addition of small black soybean lowered the hardness and chewiness of soybean curd, while it slightly increased the cohesiveness and adhesiveness. Antioxidant activities of soybean curd, soybean curd residue, and soybean curd whey were estimated by determining electron donating ability (EDA) to DPPH radical and superoxide dismutase (SOD)-like activity. These activities in all of the samples increased with the addition of small black soybean, especially in soybean curd residue and soybean curd whey; also, soybean curd whey containing small black soybean showed the highest activities.
