This study examined the growth and sensory characteristics of soybean sprout cultured at 25$\pm$1$^{\circ}C$ for 4 days with distilled water control and green tea extracted water (0.03% and 0.05%). The proximate composition of soybean sprout in the green-tea water was better than that of the control in ash, protein and fat, while the soybean sprout was especially higher in 0.05% green-tea water. The contents of vitamin C and $\beta$-carotene were higher in soybean sprout in green-tea water than the control. The total free amino acids composition of soybean sprout in green-tea water was better than that of the control, with the highest being obtained in soybean sprout in 0.03% green-tea water. Antioxidative activity was assayed by DPPH radical scavenging ability with spectrophotometer at 514 nm. The soybean sprout in green-tea water was higher than control. The amylase activity of the soybean sprout increased steadily during the first 4 days and that of the control was higher than soybean sprout in green-tea water. The proteinase of soybean sprout steadily increased during 4 day culture. Furthermore, the proteinase activity of soybean sprout in green-tea water was higher than that of the control up to 2 days. Whereas after 3 days, it was the highest in 0.03% green-tea water and then decreased remarkably in 0.05% green-tea water.

To evaluate the effect of dried barley sprout powder on muffins, muffins were made after they had been supplemented with barley sprout powder (0, 10, 20 and 30%(all w/w)). The moisture content, crude protein and crude lipid were reduced with an increase in barley sprout powder. The content of crude ash and crude fiber in the control group was significantly lower than those of the samples with barley sprout powder. The pH in the sample with barley sprout powder was lower than that of the control group. The highest specific gravity in the group with 30% of barley sprout powder was 0.84. No significant weight and baking loss rate changes were observed. The sample with no barley sprout powder showed the highest volume. The sample with 30% of barley sprout powder showed the highest uniformity. In color, the L-value and a-value of the control group were significantly higher than those of the other groups. Hardness, gumminess and chewiness of the control group showed the lowest value rather than the other groups. Springness and cohesiveness of the control group were significantly higher than those of the other groups. Crumb color, grass odor and bitter taste showed significant difference among groups. Acceptance of appearance, flavor, taste and total acceptability of groups with 10% and 20% of barley sprout powder did not show any significant difference when compared to the control group. Based on the above results, less than 20% of barley sprout powder would be proper to make muffins.

In this study, the anti-oxidative effects and components of sprout serum were investigated. In the buds, high levels of zinc, iron and manganese were analyzed in addition to copper, magnesium, and potassium. The free radical (1,1-diphenyl-2-picrylhydrazyl, DPPH) scavenging activity of sprout serum was evaluated with $IC_{50}$. $IC_{50}$ of sprout serum was $58.0\;mgmL^{-1}$, and that of vitamin C was $3.7\;mgmL^{-1}$. In the test of superoxide scavenging activity of sprout serum, the activity was dependent on the concentration of serum. In this case, the $IC_{50}$ was 2.0 wt%. Cell viability was detected by using the MTT method. Cultured human fibroblast was treated with 15 mM $H_2O_2$ and cell viability was 70% in case of control. However, the effect of treating 0.5% of sprout serum was similar to that of 0.0001% of vitamin C.

A causal agent of bacterial soft rot occurring in soybean sprout cultivation in Korea was isolated and identified, and its incidence in several sprout-soybean cultivars was examined. Infected soybean seeds became light brown and whitish, and could not germinate until 3 days after seeding, accompanying rotting of soybean seeds and sprouts. The causal organism isolated from the rotten seeds and sprouts was identified as Erwinia carotovora subsp. carotovora on the basis of its pathogenicity, morphological and physiological characteristics and the results of the Biolog GN microplate test program. The bacterial soft rot by E. c. subsp. carotovora was firstly described in soybean sprout in Korea, and we name it“the bacterial soft rot of soybean sprout”. The disease occurred more frequently in Nam-hae and Fu-reun sprout-soybean cultivars than in Eun-ha, So-baek, and Ik-san cultivars.

This study was performed to determine the optimum ratio of ingredients in the Sulgidduk with barley(Hordeum vulgare L.) sprout powder. A mathematical analytical tool was employed for optimization of the typical ingredients. The canonical form and trace plot showed the affect of each ingredient in the mixture against the final product. Mixture design showed 14 experimental points, including 4 replicates for three independent variables. The three independent variables selected for the experiment were: water($15{\sim}22%$), barley sprout powder($1{\sim}4%$), and sugar($12{\sim}19%$). The optimum responses variables such as color values(L, a, and b), instrumental texture parameters(hardness, gumminess, and chewiness), and sensory characteristics(appearance, color, smell, taste, softness, moistness, and overall acceptability) were evaluated. The Hunter colorimetric L- and a-values of the Sulgidduk decreased with an increasing amount of barley sprout powder. As more barley sprout powder was added, a higher b-value resulted. Textural hardness, gumminess, and chewiness were lowered by the addition of barley sprout powder. The optimum formulation obtained by both numerical and graphical methods showed similar results. The representative optimal ingredient ratio commonly obtained by both methods were: 18.2% water, 2.0% barley sprout powder, and 14.8% sugar.

A soybean-sprout rot epidemic occurred in a mass production soybean sprout factory in 2000 and 2001 in Korea, which caused up to 20% production loss. Among the causal pathogenic bacteria and fungi, Pythium deliense was found to be the dominant pathogen of severe root and hypocotyls rot, particularly in recirculating water system. An average of 90% of the isolated fungi from the rotted sprout on potato dextrose agar were Pythium sp. The fungal density of Pythium in the sampled water was monitored in the recycled water system for 1 year using a selective medium (com meal agar with Pimaricin, 10 mg； Rifampicin, 10 mg； and Ampicillin, 100 mg per 1 liter). The drained water from the soybean-sprout cultivation always had a certain amount of fungus in it. The removal of Pythium from the recycling water system must be thorough, safe, and environment friendly. However, the pathogen in the water was easily found even after ozone and chlorine treatments, which were devised on the recycling system for the removal of microorganisms. 5-$\mu\textrm{m}$ pore size filter was applied and was able to successfully control the disease. As the sprout industry increasingly shifts into mass production, the demand for water will increase continuously. Recycling water for sprout production is eco-friendly. However, a process must be devised to be able to first decompose organic matters before Pythium zoospores are filtered.

During the cultivation of wheat sprouts, antioxidant activity was measured during each cultivation period. Wheat sprouts from the cultivation period showing the highest antioxidant activity were added at different concentrations to make wheat sprout sulgidduk. Their physicochemical properties then were measured. As a result, when wheat sprouts were cultivated to about 14 cm, contents of ascorbic acid and polyphenol compounds were the highest. Their ABTS radical scavenging activities also showed high values. Thus, wheat sprouts grown about 14 cm were added at a concentration of 0 to 7% to prepare wheat sprout sulgidduk. The lightness (L) of the control was the highest. Redness (a) and yellowness (b) of wheat sprout sulgidduk increased as the amount of wheat sprout added increased. Contents of ascorbic acid and polyphenol compounds and ABTS radical scavenging activities of wheat sprout sulgidduk added with the highest wheat sprout content were significantly higher than those of others. Regarding the texture, the addition of wheat sprout resulted in slightly higher hardness, gumminess, and chewiness than the control. However, springiness and cohesiveness were not significantly different between treatment groups.

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.
