  • Growth characteristics and crude protein content of soybean sprouts cultivated with extracts of some Korean herb medicines for 4 days were investigated. Extracts of Korean herb medicines were utilized and adjusted to 100 ppm, 200 ppm, 300 ppm and 400 ppm as culturing water of soybean sprouts. Of Korean herb medicines tested, extract of Panax ginseng was most effective to increase of weight and length of soybean sprouts, followed by Glycyrrhiza glabra. Extracts of Angelica gigas and Cnidium officinale were similar with that of control group. Extract of Coptidis japonica inhibited the growth of soybean sprout. Optimal concentrations of extracts of Glycyrrhiza glabra and Panax ginseng for growth of soybean sprout were 100 ppm and 200 ppm, respectively. Weight of soybean sprout cultivated with extract of Panax ginseng (PGE) was increased to 7.2%(wet basis) as compared with that of control group. Length of soybean sprouts cultivated with 200 ppm of PGE was accelerated to 32% and increased to 50% in soybean sprout cultivated for 3 days. Crude protein contents of soybean sprout cultivated with extract of Angelica gigas or Panax ginseng was slightly increased according to cultivation period. In Cnidium officinale group, crude protein contents was increased at a 300∼400 ppm concentration and 4 days of cultivation.

  • 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.

  • Chunkookjang, fermented soybean is rich in diverse oligopeptides which derived from cleavage of soybean proteins during fermentation. Microarray data containing differently expressed genes in breast cancer cells treated with fermented soybean extract and well known breast cancer metastasis markers were combined, and a new network was constructed. It is used to check interactions between the marker proteins and the differently expressed genes. Based on the network analysis, PLAU (plasminogen activator, urokinase, uPA) and ERBB2 (epidermal growth factor receptor 2) are chosen as possible metastasis genes. We treated breast cancer MCF7 cells with fermented soybean extract and measured expression levels of PLAU and ERBB2. Fermented soybean extract suppressed PLAU and ERBB2 expressions conspicuously. In the cancer cells treated with fermented soybean extracts, an inflammation marker, NO production was also reduced. It will be interesting to find specific peptides to suppress PLAU and ERBB2 expressions in human breast cancer cells.

  • Wildbean(Glycine soja Siebold et Zucc.) is known as the orgin of soybean (Glycine max Merr.). Based on the hypothesis that the secondary transformation of chemical compound in wildbean might have occurred during its breed improvement to soybean. this study was carried out to compare the antioxidant activities and chemical composition in wildbean and soybean. The present study demonstrates that 1) Antioxidant activity was much higher in EtOAc, extract of wildbean than in soybean. 2) strong antioxidant activity observed in EtOAc extract of wildbean was due to the presence of (-)-epicatechin, which was not present in the extract of soybean but isolated, for the first time, from the extract of wild bean, and 3) antioxidant activity of the isolated (-)-epicatechin was greater than that of tocopherol, the previously known antioxidant.

  • Purpose: This study was performed to evaluate the effects of sannamul or herb extract addition to a soybean oil-in-water emulsion during photooxidation in the presence of chlorophyll. Methods: The emulsion mainly consisted of purified soybean oil and citric acid buffer (pH 4.0) at a weight ratio of 4 to 6, with chlorophyll a addition at 6 mg/kg. Ethanol extract of daraesoon, samnamul, basil, or peppermint was selectively added to the emulsion at 400 mg/kg, and emulsions in glass serum bottles were oxidized at $5^{\circ}C$ under 2,600 lux light for 48 hours. Lipid oxidation of the emulsions was evaluated based on determination of headspace oxygen content, peroxide value, and p-anisidine value. Pigments and antioxidants were also monitored. Results: The emulsion with added samnamul extract with high contents of polyphenols and low chlorophyll content showed lower oxygen consumption, peroxide values, and p-anisidine values, whereas basil and peppermint extracts with high chlorophyll contents increased photooxidation. Chlorophylls were degraded during photooxidation of the emulsions, and the degradation rate was highest in the emulsion with added samnamul extract. Conclusion: The high antioxidant activity of samnamul extract in the photooxidation of soybean oil-in-water emulsion could be due to low chlorophyll content, high concentrations of polyphenol compounds in the extract, as well as rapid degradation of chlorophylls during oxidation.
