Soybean and mungbean sprouts are vegetables indigenous to Korea which have been grown throughout the year from the most remote age. They had been called interchangeably as duchaeah or duah. Control method of environmental conditions for soybean or mungbean sprouts growing had been already appreciated from long time ago. A growing method once developed might have been handed over considerable period. Siroo (시루) and yongsoo (용수) had been the most common containers and the watering skill is of the utmost importance for soybean sprouts growing. As the demand of soybean sprouts in the market increased, a pit has been used for bean sprouts growing, and transformed into regular soybean sprouts factory. Now bean sprouts are international food and the demand of bean sprouts seems permanent in Korea. Accordingly the long-term policy concerned with the production of soybean sprouts should be prepared, placing emphasis on improved quality and safety.

In this study, isoflavone (genistein, genistin, daidzein, daidzin) contents in various parts of twelve soybean cultivars and three soy sprouts were determined by high performance liquid chromatography with UV detector. Three cultivars of soybean were selected and cultured in the lab to produce sprout for five days. Total isoflavone (Total IF) varied greatly among differnt breeds of soybean in range of 99 - 649.9 $\mu\textrm{g}$/g and 522.3 - 1,277.7 $\mu\textrm{g}$/g respectively, domestic and foreign cultivars. There were greatly difference in total IF of various parts of the soybean sprouts. Sprout from the Myunjunamul-kong appeared to have 69% genistein and 22% genistin in head part, and 30% and 62% of daidzin and daidzein, respectively, in root. Meanwhile, the sprouts from Junjori contains most (84%) of daidzein in its root. Sprout from chinese black-soybean had the largest amount of genistein among the sprouts but, there were no differences in the average genistein content between three selected black and non-black soys. The glycosidic form of IF were dominant compared to aglycone forms both in soybean and sprouts by 24 times and 12 times, respectively, suggesting that during the sprouts cultivation glycosidic forms could change to aglycone forms. There are no difference in total content between genistein + genistin and daidzein + daidzin in soy and soy sprout. Therfore, considering the total IF contents, the intake of 1 soy sprout is similer to 1.5 times as soybean.

The growth inhibitory effect of germanium, or soybean sprouts cultured with germanium, on cancer cells was determined in the cultured gastric cancer cell line, AGS. The growth of AGS was significantly inhibited by the addition of 0.01-1％ organic germanium (Ge-132) and germanium stone powder in MTT cytotoxicity assays. The juice from germanium treated soybean sprouts (GTS) inhibited the growth of AGS gastric cancer cells by 78-88％ at concentrations of 2.5 or 5${\mu}\ell$. The juice from Seomoktae GTS revealed an especially higher growth inhibitory effect than that from the control soybean sprouts (germanium non-treated soybean sprouts, GNTS) in AGS. The results suggest that soybean sprouts cultured with germanium may exert an anticancer effect against gastric cancer cells.

부패된 콩이나 콩나물에 존재하는 33종$(K-1{\sim}K-33)$의 각종 미생물로부터 콩나물 부패에 관여하는 세균(K-17)과 진균(K-28)을 각각 1종류씩 분리하였으며, 이들은 각각 Erwinia carotovora와 Fusarium sp.로 동정하였다. 콩나물 부패균에 길항하는 미생물은 각종 토양 균원시료로부터 분리한 350여종의 세균을 이용하여 콩나물 부패세균인 K-17 균주와 진균인 K-28 균주에 각각 길항력을 나타내는 J-232 세균을 최종 선발하였다. 길항균 J-232는 Pseudomonas fluorescens로 동정되었다. 콩나물 부패균 E. carotovora K-17과 Fusarium sp. K-28의 배양액으로 재배한 콩나물은 시루 아랫부분이 부패하였으나, 길항균 P. fluorescens J-232는 PDA 한천배지에서도 부패균들의 생육을 억제하였을 뿐만아니라 길항균 배양여액을 단독으로 콩나물재배에 처리할 경우에도 시루 내 콩나물은 부패되지 않았다. 콩나물 부패균 E. carotovora K-17과 Fusarium sp. K-28의 배양액에 길항균 P. fluorescens J-232의 배양액을 원액 또는 500배까지 희석하여 침지한 후 재배한 콩나물도 전혀 부패되지 않았으며 생육이 약간 촉진되는 경향이었다.

Most soybean sprouts grown in factories are sold on the market. When the soybean sprouts grow up to lateral root initiation, the rate and absolute amount of asparagine in the roots of all sprouts are comparatively low. To extract the greatest amount of asparagine from soy-sprouts, it is advantageous to grow sprouts more than 16 days. When sprouts were grown with ozonic water, it was possible to grow sprouts more than 16 days without any rotting problems. The content of asparagine in the sprouts were proportionally increased up to 16 days. When sprouts were grown in 0.2% of urea, the content of asparagine in sprouts were significantly increased. Soybean sprouts grown at $20^{\circ}C$ room temperature showed the highest yield rate and asparagine content, at the same time.

The purpose of this study was to estimate the growth promoting effects and improvement of antioxidant activity of the soybean sprouts treated with Chlorella sp. culture solution. The soybean sprout treated with 0.1% and 0.2% Chlorella sp. culture solution was significantly increased the length (more than 43.0%), the thickness (more than 0.5~0.7 mm), fresh weight (more than 2.9~3.7 g) compared to non-treated control in vitro. In organic soybean sprouts farm, the 0.2% chlorella culture solution applied to mass culture of soybean sprout and the fresh weight of soybean sprouts increased by more than 25% and the yield was very high as 598.33% compared to untreated control. In addition of sensory test, there is no fishy odor and better crunchy texture and nutty flavor for the treatment soybean sprouts compared to untreated soybean sprouts. Particularly, free-radical scavenging activity (DPPH) and superoxide dismutase activity (SOD) of the soybean sprouts were significantly increased more than 26.1% and 40.4%, respectively by treated with 0.1% and 0.2% Chlorella culture solution. Consequently, the treatment of chlorella culture solution to grow soybean sprouts is also promoting quality and antioxidant activity as well as promoting the growth of sprouts. Therefore, chlorella is considered to be worth as functional materials for high-quality sprouts grown.

The effects of cultivation methods (cultivation of curled-shaped type, M-1; conventional cultivation, M-2; growing after treatment with a growth regulator, M-3; cultivation by the combination of M-1 and treatment with oak charcoal, M-4) on the quality characteristics of soybean sprouts were studied by the measurement of growth characteristics. This study also investigated the changes in shelf-life stability of the new soybean sprouts (NSB) using M-4, which was cultivated with oak charcoal and treated with antimicrobial Citrus sunki seed extract. Among the soybean sprouts grown for six days at the high temperature and humidity environment (90$\pm$5% RH, 25$\pm$1$^{\circ}C$), M-1 revealed no significant difference in terms of quality, such as the harvest yield, the rot rate and the growth characteristics when compared with M-2. M-3 showed no significant difference in growth characteristics, of hardness, and sensory evaluation scores when compared with the soybean sprouts grown by conventional methods. NSB had a low number of total microorganisms and had a better appearance after five days of storage than did the control group (M-2). These findings demonstrate that chemical-free and clean soybean sprouts can be grown by combining oak charcoal and antimicrobial Citrus sunki seed extract, thereby meeting the consumer demand for safe, chemical free sprouts.
