  • This study was carried out to evaluate the nutritional value of soybean sprouts cultured in water with germanium. In the germanium treated soybean sprouts (GSP), the contents of moisture and ash were higher than those of control group (germanium non-treated soybean sprouts), with 88.7~90.2% and 16~24%, respectively. The contents of dietary fiber, vitamin C and total phenol of GSP were also higher than those of control group especially with more than 20~40% in total phenol being contained. Minerals of soybean sprouts were considerably increased during S-day cultivation. Of minerals, the contents of calcium and iron in GSP were higher than in the control. In particular there was no germanium in control group, but on the other hand, GSP had germanium of 159 ppm. Therefore, it may be suggested that, soybean sprout with germanium is better than soybean sprout without germanium in terms of nutrition.

  • To investigate the effect of the electrolyzed acidic water for soybean sprouts growth, the responses of characteristics of soybean sprouts were evaluated. Soybean sprouts grown by the electrolyzed acidic water showed shorter length in total body, root, and hypocotyl, etc. but they were evaluated to be increased in hypocotyl diameter and weight per sprout. Total length of soybean sprouts grown for 5 days by electrolyzed acidic water were much shorter than those by tap water. Soybean sprouts grown by tap water showed rapid growth in length even after 5 days but no more growth in length for those grown by electrolyzed acidic water. The growth of hypocotyl showed the same tendency as total length. No difference in root length among the soybean sprouts grown for 4 ~ 11 days by electrolyzed acidic water while those grown by tap water showed continuous rapid growth in length. The diameter of hypocotyl was thicker in those grown by electrolyzed acidic water than those grown by tap water and increased up 5 days. The weight of cotyledon grown by electrolyzed acidic water showed the proportional increase to the growing days but those grown by tap water showed no increase in hypocotyl weight up to 7 days, but a little bit increase after 11 days with the growth of new buds. The fresh weight per sprout was higher in those grown by electrolyzed acidic water until 7 days than tap water but it was the same weight in 11 days cultivation. The electrolyzed acidic water effected on shortening of hypocotyl and root length, thickening of hypocotyl diameter, and enlarging of cotyledon during soybean sprout cultivation.

  • The physicochemical and sensory properties of bean sprouts with different namulkong cultivars were examined. The five namulkong cultivars included were as follows : Nokchaekong, Dawonkong, Seonamkong, Orialtae, and Pungsannamulkong with light green, black, yellow, dark green, and yellow seed coats, respectively. The bean sprouts were cultivated in a lab and were used for analyses. The instrumental textural hardness and lipoxygenase activity of the heads were higher than those of the stems in both fresh and boiled bean sprouts. The 3 minutes of boiling caused a decrease in the hardness and lipoxygenase activity of the heads and the stems. The chlorophyll a and b contents in the heads were higher than those in the stems, and they decreased with boiling. The fresh bean sprouts with Dawonkong, Seonamkong and Pungsannamulkong showed higher acceptability than those with Nokchaekong and Orialtae. The higher acceptability was observed in the boiled and flavored bean sprouts with Seonamkong and Pungsannamulkong.

  • The physicochemical and sensory characteristics of Kongnamulguk with commercial film-packed soy sprouts from domestic cultivars were investigated. The color determination showed that the solid part of Kongnamulguk had a light green color and did not change even when cooking for 9 minutes. The solid part of Kongnamulguk was much higher in insoluble dietary fiber than soluble dietary fiber. Soluble and insoluble dietary fiber of the soy sprout tended to increase upon cooking. The acceptability of the solid part of Kongnamulguk was negatively correlated with a bean odor and flavor, and a grassy odor and flavor, but positively correlated with a nutty odor and flavor. In addition, the acceptability of the liquid of Kongnamulguk was negatively correlated with a bean odor, a grassy and bitter flavor, while it was positively correlated with a sweet flavor. These results suggest that soy sprout with a less bean odor and flavor would be highly acceptable, so it would probably be suitable for Kongnamulguk.

  • 콩나물의 생육부진과 부패는 콩나물 재배에 중요한 제한요인이다. 콩나물 부패 병원 진균으로 Fusarium moniliforme, F. oxysporum과 F. solani를 분리 동정하였다. 이들은 종자 발아 후 3∼5일이 지난후 콩나물의 중간 이하에 연한 갈색의 외부 병징을 만들며 발아 후 6∼7일 경에 병징이 더욱 진전하여 진한 갈색의 외부 병징을 나타냄으로써 콩나물에 대한 병원성이 인정되었다. Hand-section과 microtome-section에 의한 병태 조직학적 관찰에서 F. oxysporum 접종 후 4일이 경과하여 초기 병징을 보인 조직에서 균사가 피층, 세포간극, 목부, 사부, 수에 분포하고 있음이 관찰되었다.

  • Soy sprouts with Pungsannamulkong stored in covered polypropylene container with water(PCSS) or polypropylene film bag without water(PBSS) at $4^{\circ}C$ for 7 days. Changes in weight, instrumental textural hardness, color values and sensory attributes of soy sprouts were evaluated after 2, 4 and 7 day storage. Storage caused slight weight losses in PBSS, but not in PCSS. In the courses of storage the hardness of the heads decreased, while the stems maintained their hardness. The effect of storage periods on surface color changes were also determined. The stems of soy sprouts in PCSS had higher L values when stored for over 2 days. The b values of the stems in both PCSS and PBSS increased after over 2 day storage. The higher b values in the stems were found when kept in PBSS for 2 or 4 days, indicating more yellowish color. On the other hand, the heads and stems of soy sprouts had light green color. The soy sprouts in PCSS became greener with storage, but there was only small increase in greenness. Sensory panels perceived that the overall acceptability of soy sprouts decreased with storage. The overall acceptability of soy sprouts when kept in PCSS for 7 days were not as good as that of soy sprouts in PCSS for 4 days, although soy sprouts in PCSS had a significantly higher overall acceptability than those in PBSS when stored over 4 days(p<0.05). Therefore, PCSS could be possible to keep soy sprouts with good overall acceptability when stored 4 days at $4^{\circ}C$.

  • In order to cultivate the soybean sprout fortified with organogermanium, we observed growth characteristics and germanium content of soybean sprout watered with the aqueous organogermanium, Ge-132[bis(2-Carboxyethylgermanium sesquioxide)]. Soybean sprout did not show difference in growth when treated with different times and frequencies of organogermanium or different types of germanium. Growth of Orialtae soybean sprout was smaller in diameter of hypocotyledonary axis and longer in total length than that of Danyeob soybean sprout. Three hour's soaking was better in growth than half an boar's treatment. Germanium absorbed by soybean sprout was greater in content in Danyeob soybean sprout than in Orialtae soybean sprout and highest at 20 ppm in water. Prolonged period and increased frequency in treatments with organic germanium resulted in increase of germanium uptake. Germanium content in soybean sprout was greater with treatment of organic germanium than with inorganic germanium.

  • This study was conducted to determine the growth and properties of green soybean sprouts(Vigna umbellata Thunb.) in soil culture. Patkong which is a small grain variety was sawn on electric heated hot bed in the greenhouse. Temperature of the culture bed were respectively 17, 20, 25, and 30℃ and water temperature were respectively 14, 17, 20 and 25℃. The kinds of soil used for this study were upland soil, sand, peatmoss and Pearlite, loess, loess and activated carbon. BA was treated in the concentrations of 240 times, 80 times, 40 times besides control. High temperature of 25 and 30℃ increased sprout yield compared to lower temperature but caused to decay from 7 days after sawing. Thus, the most optimum temperature for soil culture was 20℃. The best soil was sand of which increased fresh weight of 850g during same period. Addition of BA was most effective to promote sprout growth in the concentration of 80 times. Compared to general soybean sprouts, green soybean sprouts were 50% higher in fiber but 72% lower in glucide. Vitamin B was 200% higher in green soybean sprouts but vitamin C was higher in general soybean sprouts.
