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.

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.

This study was conducted to assess the possibility of preserving frozen vegetables (Aster scaber, soybean sprouts, Chinese cabbage, green pumpkin, and Welsh onion) for a long period and of using them after such storage by measuring changes in quality due to their preservation. Various freshly harvested vegetables were blanched under optimal conditions (that were determined in a preliminary experiment), quick-frozen at $-40^{\circ}C$ for 24 h, and stored at $-20^{\circ}C$. The change in the chromaticity of the frozen A. scaber, soybean sprouts, Chinese cabbage, green pumpkin, and Welsh onion did not vary. The hardness of the frozen A. scaber, green pumpkin, Chinese cabbage and Welsh onion did not change during the preservation period, whereas the hardness of the cotyledon and hypocotyl of the soybean sprouts significantly increased on the sixth month of their storage. The total bacterial counts of the A. scaber during the preservation period remained constant at $10^3$ CFU/g, whereas those of soybean sprouts, Chinese cabbage, green pumpkin, and Welsh onion decreased slightly to $10^2$ CFU/g. Coliform was not detected in any of the samples. The sensory evaluation showed that the preservation period that was used in this study did not significantly affect the marketability of the frozen vegetables. Therefore, it was considered that A. scaber, soybean sprouts, Chinese cabbage, green pumpkin, and Welsh onion can be safely preserved by freeze-storing them for up to 12 months.

This study was performed to set a limitation rule to the UV sterilization process for green vegetable juice containing barley sprouts. The main constituents of the green vegetable juice, viz. barley sprouts, organic Angelica keiskei, carrots, organic dandelion, kale, wild parsley, Angelica keiskei and cabbage, were provided by the CSJ company located in Jincheon, Chungbuk, from December 1st, 2015 to March 1st, 2016. Our manufacturing process followed the general manufacturing process of a general green vegetable juice manufacturer. Table 1 shows the mixing ratio for the green vegetable juice. This green vegetable juice includes 18% vegetable sprouts, 3% barley sprouts, 18% angelica utilis makino, 1% orange concentrate, 4% apple concentrate, 6% fructooligosaccharide, 10% vegetable fermentation juice, 0.4% lemon concentrate and 39.6% purified water. We conducted UV sterilization at levels 10, 8 and 5 with powers of 230W, 320W and 320W, respectively. The UV sterilization was conducted twice at 25Hz and then once at 40Hz. In the bacterial tests after sterilization, the number of bacteria in the dandelions decreased from $2.56{\times}10^8CFU/mL$ to $5.96{\times}10^3CFU/mL$. In addition, no food poisoning or coliform bacteria were detected. Thus, this study provides the information required for setting a limitation rule using bacteria tests in the UV sterilization process for green vegetable juice.

We analyzed the ${\gamma}$-aminobutyric acid (GABA) content of a selection of uncooked foods. Foods with GABA concentrations in excess of 100 nmole per g dry weight included: brown rice germ, brown rice sprouts, barley sprouts, bean sprouts, beans, corn, barley, brown rice, spinach, potatoes, sweet potatoes, yams, kale and chestnuts. Cereals included: brown rice germ, brown rice sprouts, barley sprouts, bean sprouts, beans, corn, barley, and brown rice and had GABA concentrations of 718, 389, 326, 302, 250, 199, 190, and 123 nmole per g dry weight (DW), respectively. The vegetables: spinach, potatoes, sweet potatoes, yams and kale contained 414, 166, 137, 129, 122 nmole GABA per g DW, respectively. The GABA concentration of chestnut was 188 nmole per g DW. However, oatmeal, adlay, broccoli, squash, carrots, onion, apples, lentinus edodes, green laver, and lactobacillus had GABA concentrations of less than 100 nmole per g DW. These results show that brown rice germ, sprouted cereals and spinach are good sources of plant-derived GABA. These data will be useful in selecting foods for the manufacturing of uncooked foods containing a relatively high concentrations of GABA.

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 $4^{\circ}C$.

This study was conducted to elucidate the characteristics of soybean sprouts cultured in water containing germanium. In three varieties of Eunhakong, Seomoktae and Subaktae, the yields of germanium soybean sprout were 10~20% more than those of control soybean sprouts after 5 day-cultivation. The hypocotyl of germanium soybean sprouts was thicker than that of control soybean sprouts, but there were no significant differences in the length of hypocotyl and the thickness of cotyledon. Germanium soybean sprouts showed deeper green and yellow color than control soybean sprouts. In addition, the hardness exhibited strongly in germanium soybean sprouts, especially Seomoktae. In the sensory evaluation, germanium soybean sprouts were better than control soybean sprouts in appearance, taste, flavor and preference.
