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.

This study was conducted to investigate the detoxification effect of extract from soy-sprout grown using high concentrated oxygen water extract (SE) against alcohol-induced hangover in male Sprague-Dawley (SD) rats. The rats were orally administered with different concentrations of SE beverage [26, 260 and 2,000 mg/kg body weight (b.w.)] and, after 30 min, with alcohol at a dose of 3 g/kg b.w. After 1 and 3 h of alcohol administration, blood was collected from the retro-orbital plexus, while after 5 h, blood was collected from the heart. In the 2,000 mg/kg b.w. SE group, the concentration of blood alcohol was significantly reduced after 1-5 h of alcohol loading as compared with that in the other groups. In addition, the blood acetaldehyde concentration was reduced by SE (2,000 mg/kg b.w.). These results suggest that SE beverage can alleviate alcohol hangover symptoms by stimulating the activities related to hepatic alcohol-metabolizing enzymes.

Soy sprouts cultured in a lab with five soybean cultivars and three commercial soy sprouts purchased in a market were investigated to compare the mineral and vitamine contents. In case of minerals, K, Ca, Mg, and Na were found as major minerals and a small quantity of Fe, Zn, Mn, and Cu was also analyzed in soy sprout. The all minerals were distributed in the cotyledon and the hypocotyl but their concentration orders were different between in cotyledon and in hypocotyl. After boiling, much of minerals eluted in water, the pattern of release of the minerals from the soy sprout to water was similar in all soy sprouts. The vitamin C was concentrated a great amount in hypocotyl than in cotyledon whereas vitamin B was found in the cotyledon generally. And their contents were reduced after boiling owing to heat-mediated degrading. The vitamin C and B contents were different according to cultivars, which shows chemical composition of soybean seed was important to soy sprout characters. The present results provide a basis for attempt to improve seed quality in soybean breeding program for soy sprout.

This study was performed to investigate the content of residual pesticides in bean sprouts which are the very important vegetables to supply protein for traditional korean dishes. Experimental subjects included 541 cases of bean sprouts and 168 cases of germinating beans collected in the Seoul area from January in 1987 to February in 1938. In residual pesticides of subjects, topsin-M, vitavax and thiram were determined by high pressure liquid chromatography and captan was determined by gas chromatography. The detection rates of residual pesticides in the subjects were 19.4% in bean sprouts and 26.2% in germinating beans. The most common used pesticides in bean sprouts was topsin-M and detection rate was 16.2%. Captan and vitavax were also detected in about 3.5%, 2.8% of the experimental subjects respectively. But thiram was not detected in any samples. The mean value of topsin-M content was $21.32{\pm}4.82ppm$ and $1.68{\pm}0.14ppm$ in bean sprouts. The mean value of captan were $7.70{\pm}2.13ppm$ and $0.42{\pm}0.02ppm$ in germinating beans and bean sprouts, respectively.

The physicochemical and sensory characteristics of commercial film-packed soybean sprouts from domestic cultivars were investigated. The hardness of the cotyledons was higher than that of the hypocotyls in fresh and cooked soybean sprouts (Kongnamulmuchim). Furthermore, the color determination showed that the hypocotyls and cotyledons of the soybean sprouts had a light green color that was not eliminated by cooking. The acceptability of fresh soybean sprouts was negatively correlated with a beany odor, beany taste, and grassy taste, but positively correlated with a nutty odor, nutty taste, and sweet taste. In addition, the acceptability of boiled soybean sprouts was negatively correlated with a beany and grassy taste, and positively correlated with a nutty odor and taste. Furthermore, the acceptability of cooked soybean sprouts was negatively correlated with a beany odor, beany taste, grassy odor, and grassy taste, while it was positively correlated with a nutty odor and taste. Finally, the lipoxygenase activity of the cotyledons was higher than that of the hypocotyls in fresh and boiled soybean sprouts.

Commercial value of soybean sprouts should be affected by their morphology including the lateral roots. This study was carried out to determine the effect of benzyladenopurine (BA) concentration on growth and morphology of soybean sprouts in order to compare them with the selling products collected from the markets. Four cultivars (cv. Eunhakong, Pungsannamulkong, Sowonkong, and Junjery) were cultured for 6 days after imbibed for 5 hours into different BA solutions (0, 1,2,4, and 8 ppm). On the 6th day, hypocotyl length was measured to calculate the composition rate of ＞ 7 cm (A), 4 to 7 cm (B), ＜ 4 cm (C) and non-germination (D), and the ratio of hypocotyl to root length (H/R ratio) on the base of hypocotyl length as well as lateral root, hypocotyl diameter, and fraction fresh and dry weights. The composition rates classified with hypocotyl length showed big differences between 4 cultivars in class A and C; Class A, in which cv. Sowonkong and Junjery had higher rates than cv. Eunhakong and Pungsannamulkong, was decreased with BA concentration of higher than 4 ppm, but class C showed the reverse result to class A. Any lateral root was not formed in higher than 4 ppm BA solutions although fewer in cv. Pungsannamulkong and Junjery than in the two other cultivars. Hypocotyl and root lengths were decreased with increased BA concentrations, and in all BA concentration, hypocotyl length of cv. Junjery was the longest. Hypocotyl diameter, hypocotyl and total fresh weights were thicker and heavier in 2 to 4 ppm BA concentrations than in the other ones, although in case of BA application, cv, Eunhakong and Sowonkong were heavier. The H/R ratios were increased with increased BA concentration. The ratios of nearly all the selling products ranged from 1 to 2 ppm when compared to them from our experiment.

1. IAA showed no significant growth of root primordia and then lateral root emerged at 2 days after IAA treatment. BA treatment, however, strongly inhibited the formation of root primordia and a few lateral roots, if any, emerged about 5 days after treatment. 2. Treatment of BA and Indol-B on the water retaining ability sampled 1, 3, 5 days after chemical treatment was apparent on the soybean sprouts sampled 5 days after treatment while the difference among the treatments was negligible when sampled 1 and 3 days after treatment. 3. BA stimulated ABA content in the hypocotyl while inhibited ABA content in the root of soybean sprouts. ABA may relate with water retaining ability. 4. Soaking the soybean seeds to several seed disinfectant chemical solution had no effect on the growth and elongation of soybean sprouts. 5. It can be recommended that container of soybean sprouts should be shut tight during growing period except irrigation because the ethylene accumulation in the container may stimulate hypocotyl swelling and inhibit length of soybean sprouts.
