  • This study was investigated the optimal time that enhanced the functional activities of mung beans for use of functional food resources. Mung beans were roasted according three levels of roasting time levels (10, 20 and 30 minutes) at $110^{\circ}C$ and then the physicochemical compositions were determined. The reducing sugar content was decreased with the increased roasting time. Moisture was decreased with increased roasting time, whereas, crude fat, crude ash, crude protein and carbohydrate were increased with prolonged roasting time. The highest contents of total phenol and flavonoid were shown at a roasting condition $110^{\circ}C$ for 30 minutes. The highest inhibitory activities of DPPH radical, ABTS radical and xanthine oxidase was the best at the condition of $110^{\circ}C$ for 30 min. From these results optimal roasting time of mung beans were 30 minutes for use of functional food resources.

  • Legumes are one of the largest families of crop plants and are widely consumed and produced for their nutritional and commercial benefits. Mung bean (Vigna radiata L.) is a legume crop that contains various functional compounds ; moreover, it has strong antioxidant properties and is becoming an increasingly important food crop. However, most previous studies on mung beans have focused on their primary metabolites. In this study, we investigated the composition and contents of phenolic compounds, fatty acids, soyasapogenol and tocopherol in mung beans cultivated in different regions and cultivated at different seeding dates. Material analysis was conducted using the following methods: LC-MS/MS, GC-FID and HPLC-ELSD. In total, 57 different samples were analyzed. Thirteen phenolic compounds were detected in mung beans. Of these, vitexin and isovitexin were the most abundant compounds, accounting for approximately 99% of phenolic compounds. The difference in phenol compounds according to the seeding dates of mung bean was not statistically significant. The total fatty acid content in beans was the highest in Pyeongchang. Significant differences in total fatty acid content were found according to the cultivation regions. Crops grown in Sohyeon and Dahyeon showed the highest soyasapogenol B content in the Suwon region, and these were the lowest in Jeonju. The total tocopherol content of beans cultivated in Dahyeon and Sohyeon was the lowest and highest in Pyeongchang. Soyasapogenol B and total tocopherol content were not significantly different according to seeding dates. This study was conducted to obtain basic data for the cultivation of mung beans with a high content of various functional materials in terms of regional specialization and optimal seeding time.

  • To examine changes of antinutritional oligosaccharides, particularly raffinose and stachyose, of mung beans during germination, mung beans (Phaseolus aureus) were germinated at $25^{\circ}C$ for 7 days after soaking for 15 hr. The 80% ethanol extracts of mung bean sprouts were analyzed by Kieselgel thin-layer chromatography using a solvent system, ethylacetate, acetic acid and water (3:1:1, v/v). The moisture level was increased greatly after soaking followed by stabilization along to the 3rd day of germination. The level was increased slightly on the 4th day and thereafter stabilized. Antinutritional oligosaccharides, raffinose and stachyose was diminished significantly on a thin-layer chromatogricadtly on the 1st and 2nd day of germination, and disappeared almost thereafter.

  • This work is an extension of my work presented a robust and economically efficient method for the Discrimination of four Mung-Beans [1] varieties based on quantitative parameters. Due to the advancement of technology, users try to find the solutions to their daily life problems using smartphones but still for computing power and memory. Hence, there is a need to find the best classifier to classify the Mung-Beans using already suggested features in previous work with minimum memory requirements and computational power. To achieve this study's goal, we take the experiments on various supervised classifiers with simple architecture and calculations and give the robust performance on the most relevant 10 suggested features selected by Fisher Co-efficient, Probability of Error, Mutual Information, and wavelet features. After the analysis, we replace the Artificial Neural Network and Deep learning with a classifier that gives approximately the same classification results as the above classifier but is efficient in terms of resources and time complexity. This classifier is easily implemented in the smartphone environment.

  • This study was performed to determine the optimal roasting temperature of mung beans for enhancement of antioxidative activities. Mung beans were roasted various roasting temperatures ($90{\sim}120^{\circ}C$ for 20 minutes), after which physicochemical compositions were determined. Variations in pH from 6.1 to 6.3, and reducing sugar content was highest in raw mung beans. Moisture decreased with increasing roasting temperature, whereas crude fat, crude ash, crude protein and carbohydrate contents showed no significant differences according to roasting temperature. The highest total phenol and flavonoid contents were under roasting conditions of $110^{\circ}C$ for 20 minutes. The highest DPPH radical, ABTS radical, and xanthine oxidase inhibitory activities were under conditions of $110^{\circ}C$ for 20 minutes. From these results, optimal roasting temperature of mung beans as a functional food resource was 110.

  • New lectins, lymphoagglutinating lectins from mung beans (MBLA) have been isolated and purified. Mung beans crude extracts were made with 0.15M NaCl and these were purified through anionic exchange chromatography. Four fractions were obtained from DEAE Sephadex A-50 by salt gradients elution. Lectin activity, enzyme activity, protein assay, identification of purity by polyacrylamide gel electrphoresis and immunochemical studies were carried out with these four fractions. Through these results, it can be suggested that 0.2M fraction is newly found potent MBLA. There were some relationships with MBLA and L-PHA but no similarities were observed between MBLA and E-PHA.

  • Some minor Korean beans including red bean, mung bean and kidney bean were subjected to proximate analysis, fractionation by the solubility method and polyacrylamide gel disc electrophoresis of proteins to obtain the following results. 1) Proximate composition of the beans showed that fat content was less than 1%, carbohydrate was about 60% and protein content was in the range of $20{\sim}25%$. 2) Total globulin content of the proteins was $46{\sim}59%$, a little lower than in soybean, in the order of mung bean> kidney bean> red bean. Albumin content was comparable in kidney bean, and lower in red bean and mung bean as compared with that in soybean. Glutelin content was relatively higher, being in the range of $10{\sim}19%$ and in the order of red bean> mung bean> kidney bean. 3) According to the electrophoretic pattern, total protein fractions extracted with pH 7.6 buffer from red bean, mung bean and kidney bean showed 9.12 and 11 bands, respectively, whereas those extracted with pH 4.8 buffer showed 13, 13 and 12 bands, respectively. Water extracts of red bean, mung bean and kidney bean showed 10, 8 and 9 bands, respectively, while albumin fractions showed 8, 9 and 7 bands and globulin fractions, 4 bands in all of three beans. The band having a Rm value of $0.5{\sim}0.7$ in the globulin fraction from three beans was not observed in the water extract and appears to be specific to water insoluble globulin.

  • Mung bean (Vigna radiata L.) is an increasingly important human food source, as well as a new functional agent, mainly due to its potent antioxidant activity. This study was conducted to determine antioxidant activity of fractions from mung bean seeds by measuring DPPH radical scavenging activity and to quantify the flavonoids by means of HPLC analysis. Vitexin and isovitexin were present in both ethanol and water extracts in highest amount. Flavonoids, vitexin and isovitexin were quantified from 195 germplasms of mung beans and their concentrations varied by 4.7 fold. Especially, the breeding line KM99004-4B-2 (Suwon28/KM94004), which has grown in Jeollanamdo Agricultural Research and Extension Services, showed the highest amount (15.88 mg/g) of total flavonoids. The vitexin portion was averaged $70.73{\pm}1.38\%$. High positive correlation $(r=0.96^{***})$ between vitexin and isovitexin contents showed. However, the flavonoid content showed very low correlation with the 24 growth and ecological characteristics. Seed coats of mung beans had the highest flavonoid amount, showing $50\~70$ times more than cotyledons. Flavonoid contents in the seed, the cotyledon, and the seed coat were decreased as the seed imbibition time increased.

  • This study was conducted to investigate the isoflavone (daidzein and genistein) contents, and the antioxidative and fibrinolytic activities of red and mung beans. Daidzein was not found in either the red or mung beans. The genistein contents of the red and mung beans were 40.7 and 27.8 mg/kg, respectively. Both samples had very high electron donating abilities and SOD-like activities. Fibrinolytic activities were not detected in the crude mung bean extract, but fibrinolytic substances were purified or activated under various pH conditions and with heat treatments. With heat treatment at 100 $^{\circ}C$ for 10 min, the specific activity was increased 4.61 fold. This study revealed that, although red and mung beans were poor in isoflavone, they could be good sources for functional products due to their strong antioxidative activities and heat- and acid-resistant proteolytic abilities.
