  • In this study, ${\beta}$-carotene concentrations was determined in soybean cultivar according to seed size, usage, seed coat color and cotyledon color as well as the process of seed germination. The total average concentration of ${\beta}$-carotene was $6.6{\mu}g/g$ in soybean seed, $33.3{\mu}g/g$ in soybean sprout. According to seed size, the total ${\beta}$-carotene concentration of soybean was $6.9{\mu}g/g$ in large soybean seed, $6.7{\mu}g/g$ in medium soybean seed, and $6.31{\mu}g/g$ in small soybean seed. In soybean sprout, the total ${\beta}$-carotene concentration was $21.4{\mu}g/g$ in large soybean sprout, $30.5{\mu}g/g$ in medium soybean sprout, and $43.5{\mu}g/g$ in small soybean sprout. According to the utilization of seed, the total ${\beta}$-carotene concentration of soybean seed was $7.2{\mu}g/g$ in cooked with rice soybean seed, $6.1{\mu}g/g$ in paste and curd soybean seed, and $6.3{\mu}g/g$ in sprout soybean seed. In soybean sprout, the total ${\beta}$-carotene concentration was $25.9{\mu}g/g$ in cooked with rice soybean sprout, $32.4{\mu}g/g$ in paste and curd soybean sprout, and $41.9{\mu}g/g$ in sprout soybean sprout. When comparison with seed coat color, the total ${\beta}$-carotene concentration of soybean with brown seed coat ($8.8{\mu}g/g$) was slightly higher than those of soybean with yellow ($6.1{\mu}g/g$). In soybean sprout, the total ${\beta}$-carotene concentration was $21.8{\mu}g/g$ in black seed coat sprout, $38.7{\mu}g/g$ in brown seed coat sprout, $34.1{\mu}g/g$ in green seed coat sprout, $39.5{\mu}g/g$ in yellow seed coat sprout, and $30.5{\mu}g/g$ in mottle seed coat sprout. The results of this study suggested the functional characteristics of soybean through quantitative analysis of ${\beta}$-carotene.

  • Riptortus clavatus, one of the many insects in major crops, damages pods and seeds, which reduces seed vigor and viability in soybeans. This study was conducted to examine the effect of diversely damaged seeds by R. clavatus on seed germination and seedling emergence and to determine the association of damaged seed with quality and yield of soybean sprouts. All seeds damaged by R. clavatus significantly (P<0.05) reduced seed vigor as measured by the rates of seed germination, germination speed, and seedling emergence. Mean seed germination rate of non-damaged seeds in sprout-soybean varieties was 97.8%, whereas the rates of seeds damaged at different levels, 31-50% and 51-80%, were 23.0 and 5.4%, respectively. The rates of seedling rot and abnormal, incomplete germination significantly (P<0.05) increased as the amount of seeds damaged by R. clavatus increased to 5, 10 and 15% against the total seeds for sprout production. Yield of soybean sprouts from seeds damaged at different levels decreased up to 13% as compared to that in normal seeds. In customer preferences on soybean sprout produce, 84% of customers participated in survey preferred to purchase sprouts from seeds with 5% of damaged seeds, but sprouts produced from seeds with 15% of damaged seeds were intended to purchase only by 22% of the customers. Areas of the seed damaged by R. clavatus were readily infected by pathogens as the seed germinated, resulted in deteriorated quality and reduced yield of sprout produce.

  • This experiment was conducted to investigate the endophytic bacterium Herbaspirillum spp effect on seed germination and sprout growth of tartary buckwheat. Inoculant concentration (%v/v) and seed soaking time were applied 10, 20 and 40% and 0, 4, 8, 12 hour, respectively. The experiment was carried out in a growth chamber maintained temperature at 20, 25 and $30^{\circ}C$ without light for 7 days. Results showed that, 10 to 20% (v/v) inoculant concentration by 4 to 8 h seed soaking time at $20^{\circ}C$ temperature increased seed vigor rate and total seed germination rate 80-95% and 90-100%, respectively. On the other and, seed inoculation with Herbaspirillum spp. increased hypocotyl length (13-15 cm), root length (8-11 cm), total fresh weight (135-296 g) and total dry weight (7-10 g), compared to control. It is indicated that sprouts growth and yield depends on inoculation concentrations, seed soaking time and temperature. Therefore, it would be suggested that seed inoculation with Herbaspirillum spp. at concentration of 10 to 20% (v/v), soaking time 4 to 8 h and temperature $20^{\circ}C$ promote seed germinations and sprout growth rate of tartary buckwheat.

  • Isoflavone content in various parts of six soybean cultivars and soybean sprout during germination was analyzed by high performance liquid chromatography. The parts analyzed were seed coat, cotyledon, and axis for seeds and whole sprout, root, hypocotyl, and cotyledon for sprout. Two cultivars, Aga3 which is known to have the smallest seed size and the highest isoflavone content among the Korean soybean cultivars and Pungsannamulkong which is the most widely being used as soy-sprout, were selected for sampling from 1 to 10 days after germination. At the same weight, the order of isoflavone content increased from seed coat to cotyledon to axis. The highest total isoflavone(isoflavone$\times$dry weight) content was observed in the cotyledon and the lowest in the seed coat. The cotyledon of the Aga3 variety had the highest total isoflavone content and the lowest was measured in the Pungsannamulkong variety. The highest total isoflavone content, $10,788{\mu}g/g$, was observed in whole sprouts(cotyledon+hypocotyl+root) on day 7 for Aga3. After day 7, there was a decreasing trend in isoflavone content as the germination period increased. Total isoflavone content in the cotyledon of Aga3 significantly increased after seed germination, whereas the isoflavone content in the cotyledon of Pungsannamulkong decreased. However, total isoflavone content in the root of both varieties increased while isoflavone content in the hypocotyls decreased after seed germination.

  • The present study was conducted to determine a high-fiber variety of sprout bean and bean sprout. Sixty-six varieties of Korean sprout beans and thirty varieties of Korean bean sprouts were analyzed for their total dietary fiber (TDF) using a combination of enzymatic and gravimetric methods adopted by AOAC. The average and range of the TDF contents of the 66 varieties of sprout beans were 21.73$\pm$2.43% and 16.60~29.2% (dry basis), respectively. The top five types of sprout beans with high TDF anions the 66 samples were KLG10658 (29.2%), Dawonkong (28.46%), Sohokong (25.66%), Moohankong (25.465%) and Samnamkong (24.94%). The mean TDF content of sprout beans was relatively high in the variety with yellow seed coat color and a smaller seed size (<15 g/100 seeds) than the ones with other colors and of medium or large seed size. The average and range of the TDF content of the 30 varieties of bean sprouts were 24.48$\pm$3.9% and 18.3~33.38%, respectively. Dawonkong sprouts showed the highest TDF content (33.38%). The average TDF content of bean sprouts was 1.16 times higher than that of the corresponding seed beans. The TDF content of bean sprouts did not significantly change during the days of culture. The TDF content in the different parts of the bean sprout were high in the order of roots, hypocotyl and cotyledon.

  • Seed, stem and sprout of F. tataricum were separately milled using the ultra fine mill under the same condition to investigate the effect of roasting or extruding on the particle size, microstructure and water solubility of dietary fiber. The mean particle size of MR (roasting) is increased in stem and sprout, and that of ME (extruding) is increased in seed, compared to that of control. The microscopic views of seed show that control has the spherical shape but ME the larger and irregular shape, and those of stem and sprout show that control has the needle like shape but ME more rounded shape. Water solubility index of ME is much higher than that of control or MR in seed, stem and sprout. It shows that seed, stem and sprout are damaged more in extruding than in roasting, and the starch and cell wall structure must be destroyed to change the water insoluble dietary fiber into the water soluble dietary fiber.

  • Soybean sprouts have been a considered a nutrient-rich vegetable for hundreds of years. To evaluate the seedlot quality of soybean sprouts grown, and to evaluate a method for reducing the presence of improper seeds in soybean seedlots, microbes associated with soybean sprout rot were isolated from samples collected. Morphological characteristics and gas chromatography profiles of the cultured fungal and bacterial strains were identified. Eight types of improper seeds were identified: purple stain(Ps), black rot(Br), seed coat black spot(Cb), wrinkled seed(Ws), brown hilum(Bh), seed coat fracture(Cf), unripe seed(Us), and brown seed coat(Bc). The improper seeds were also dipped into 15%, 20%, and 25% NaCl solutions, as well as a saturated solution of NaCl, for 1min. As the NaCl concentration increased, the number of floating improper seeds increased as well. The highest floating rates were observed for the Cf seeds.
