        This study compared the antioxidant and mineral properties of the leaves and seeds of fifteen Korean adzuki bean (Vigna angularis L.) breeding lines. This study was conducted in an attempt to expand the use of Korean adzuki bean leaves. The potassium, calcium, magnesium, and sodium contents of the leaves were significantly higher than the seeds, in particularly, the potassium content. The leaves had approximately 3.3 times higher potassium content than the seeds. For instance, the potassium content of YA1317 leaves was 21% higher than that of Arari. The total polyphenol content and ABTS activity of Adzuki bean leaves were significantly higher than the seeds, as opposed to the total flavonoid content and DPPH scavenging activity. Among the 15 breeding lines, YA1402 had 1.2~3.2 times higher antioxidant content and activity as compared to the Arari variety. It was concluded that adzuki bean leaves had higher mineral content, antioxidant component and activity as compared to the seeds. Therefore, adzuki bean leaves could be used an ingredient for dishes and as a medicine.

        Sorghum is a rich source of various phytochemicals including phenolic compounds that have potential to significantly benefit human health. Phytochemical production may be induced not only by genotype but also by a number of environmental factors including temperature and an amount of sunshine. The objective of this study was to determine the effect of planting dates and harvesting stages on the quality traits of ‘Donganme,’ a grain sorghum variety developed to produce high antioxidants. ‘Donganme’ was planted in three locations on four dates from early May to early July. Each planted fraction was harvested 35, 40, 45, 50, and 55 days after the head shooting date, respectively. The results showed that significant differences existed between the growth period and content of polyphenol and flavonoid. The sorghum harvested at 35 days after head shooting had the higher polyphenol and flavonoid content in all planting times and the tannin content was increased as the planting date was delayed. So the sorghum grown in late planting dates (July 5) had highest polyphenol content (2.07 gGAE/100g) at early harvesting (35 days) while late planting gave the low grain yield (1.3 ton/ha). Polyphenol index to average temperature during 35 and 45 days after heading of ‘Donganme’ showed that total polyphenol contents were decreased by 5.2% and 4.4%, respectively, with increasing average temperature of 1oC. And high correlation (R=0.85) was observed between accumulated temperature and the amount of polyphenol of ‘Donganme’, confirming the major contribution of the quality traits is temperature. To produce high quality grain from sorghum the relation between the yield and nutrition components must be considered simultaneously (i.e., Sorghum produced the highest polyphenol and flavonoid when planted in June 15 and harvested at 40 to 45 days after head shooting .

        In the past years, few grain sorghum varieties with limited yield potential have been developed and grown in Korea. Hybrids tend to be more productive and resistive to unfavorable environmental conditions than pure line varieties. However, no hybrid cultivars are available and never have been planted for grain sorghum in Korea. The main aims of this study were to (i) verify if US x Korean and US x US hybrids increase grain yield in Korea; (ii) assess the performance of waxy hybrids in Korea and the US; (iii) estimate general combining ability and specific combining ability for the lines studied; and (iv) identify superior lines and hybrids for future use in breeding. Two distinct sets of waxy-endosperm sorghum hybrids derived from Korean landraces and US lines (Texas A&M University) were tested in the US and Korea. Compared to the parental lines, hybrids derived from US lines and Korean landraces showed yield increase that ranged from 2% to 127%. Hybrids created from US lines showed higher heterosis than US x Korean hybrids. Hybrid vigor was observed in the US and Korea, but shifts in ranks of hybrid performance occurred. The results indicate that it is feasible to develop grain sorghum hybrids adapted to Korean conditions only if delibrate selections take place in Korea. A combination of Korean and US sources could provide an acceptable germplasm base for developing Korean landrace based sorghum hybrids.

        This study was conducted in order to investigate the antioxidant capabilities and quality characteristics of instant porridge made of foxtail millet (Setaria italica Beauv.) from different varieties with different endosperm characteristics and processing using different methods. The two foxtail millet varieties used in this study were waxy foxtail millet, ‘Samdachal’, and non-waxy foxtail millet, ‘Samdame’. The means of processing food to create instant porridge were dry cereal frying, wet cereal frying, freeze drying after steaming, popping, and no treatment. The WAI (water absorption index) of instant porridge made of waxy foxtail millet was higher than that of non-waxy foxtail millet, and popping created the highest WAI among the treatments tested. Whean we analyzed RVA characteristics of non-waxy foxtail millet instant porridge, peak viscosity and setback values were decreased in all processed foxtail millet instant porridge compared to non-waxy foxtail millet instant porridge. In waxy foxtail instant porridge, the peak and final viscosities of processed treated instant porridge increased. The viscosity just after pouring hot water into the instant porridge was higher in waxy foxtail millet porridge treated by freeze drying after steaming, popping, and wet cereal frying; the viscosity of non-waxy foxtail porridge was increased after popping as compared with the other treatments. The polyphenol contents and antioxidant activities were increased in all processed, treated-instant porridge except for freeze dried porridge after steamingnt. The popping treatment showed the highest polyphenol contents (1.5 fold), and ABTS antioxidant activity (1.2 fold), compared to no treatment. Non-waxy foxtail millet porridge produced by popping earned the highest sensory evaluation scores.

        We evaluated the antioxidant properties of adzuki beans and the quality characteristics of sediment using various cultivation methods. There were significant differences in total polyphenol and flavonoid contents in beans grown using different methods of cultivation (p<0.05). Also, DPPH and ABTS radical-scavenging activities were significantly different depending on cultivation method (p<0.05). The sediment yield before drying of Chungju-pat, Hongeon, and Arari was 296.64~339.01, 271.36~282.24, and 268.21~292.32%, respectively, and the sediment yield after drying was 71.68~85.41, 77.90~85.19, and 74.15~78.65%, respectively. The L-value of Chungju-pat and Arari sediments revealed a significant difference given different cultivation methods (p<0.05), but Hongeon sediment did not show a significant difference. There was a significant difference in the a- and b-value of adzuki bean sediments cultivated using different methods (p<0.05). The particle size of Chungju-pat, Hongeon, and Arari sediments was 66.21~98.80, 61.62~97.07, and 82.96~106.71 μm, respectively, and all were significantly different depending on cultivation method (p<0.05). There were also significant differences in the water absorption index, water solubility index, and swelling power when different cultivation methods were used (p<0.05).

        Two sorghum(Sorghum bicolor L. Moench cv. Hwanggeumchal-susu and Miryang 3) samples were milled using different milling methods, and their physicochemical properties were tested. Particle size was classified into five groups such as pin mill and low temperature-microparticulation(LTM; 10, 000, 20, 000, 30, 000, and 40, 000 rpm). The water absorption index (WAI), water solubility index(WSI), and a rapid Visco analyzer(RVA) were used to examine particle size distribution and color differences. Particle size of sorghum flour prepared using LTM was lower than that prepared using a pin mill. Particle size was further reduced by successive dry milling of the LTM flour. Lightness of colored pigments increased when particle size decreased. The WAI of Miryang 3 pin milling(M1) flour was the lowest after LTM, and WSI was higher in the order of M2, M3, M4, and M5. LTM sorghum flour had significantly higher pasting viscosity, as determined using a rapid Visco analyzer. LTM Miryang 3 sorghum flour(M2~M5) flour showed lower breakdown viscosity and higher final viscosity compared to those of M1 flour, resulting in an increased setback value.

        The purpose of this study was to evaluate the appearance, sensory and physicochemical characteristics of muffin added glutinous(GSP) and non-glutinous sorghum powder(NGSP). As increasing the amounts of sorghum powder, proximate (moisture, ash and protein) and minerals composition(K, Ca, Mg and Na) of muffin were significant difference. The weight, volume, height, lightness(L-value) and yellowness(b-value) were decreased as increasing the amounts of sorghum powder. In the results of sensory evaluation, appearance, color, flavor, taste, texture and overall quality of untreated muffin were 1.4, 1.6, 1.4, 1.0, 1.1 and 0.9, and muffin added 10% GSP and NGSP were scored relatively high. Antioxidant compounds contents of muffin added sorghum powder were increased as increasing the amounts of sorghum powder. DPPH and ABTS free radical scavenging activities on methanolic extracts of untreated muffin were 0.74 and 1.31 ㎎ TE/g ER, respectively. DPPH and ABTS free radical scavenging activities of 100% GSP muffin were 9.40 and 19.14 ㎎ TE/g ER, and 100% NGSP muffin were 10.59 and 18.78 ㎎ TE/g ER, respectively. The results of this study show that notable antioxidant compounds and antioxidant activity on muffin added sorghum powder are considered to have significant health benefits.

        ‘Daname’ is a foxtail millet(Setaria italica Beauv.) variety developed and registered by Department of Southern Area Crop Science, NICS, RDA in 2014. This variety which collected from IT252182 was developed through pure line selection. ‘Daname’ is a early-maturing variety having 100 days of growth period from seeding to harvesting in Milyang of Korea. The culm length is about 97 cm which is 20cm shorter culm length than standard variety ‘Hwanggeumjo’, and it showed tolerant to lodging in field. The panicle shape is a cylindrical and the length is about 19cm. According to the grain, seed color and dehusked grain colors are orange and yellow and endosperm characteristic is non-glutinous. The yield performance of this variety was about 3.81 t ha-1 in local adaptability test from 2013 to 2014 and it showed similar with standard variety ‘Hwanggeumjo’. As the addition amount of ‘Daname’ in rice increased from 0% to 30% and 100%, the antioxidant ability of ‘Daname’ added rice and hardness/stickiness balances were increased. But we could not find out the difference of hardness/stickiness balances between 0%and 10% addition. So, 10% addition amount was concluded to increase antioxidant ability regardless eating quality of cooked rice. (Variety registration No. 6243)

        This study investigated the changes in yields, antioxidant compounds, and antioxidant activities among 11 adzuki bean cultivars cultivated in a paddy field with somewhat poorly drained soil. The adzuki bean cultivars were cultivated in the paddy field from 2015 to 2016 in Milyang, Gyeongsangnam, Korea. Average soil moisture content was 16.5% in 2015 and 31.0% in 2016 at the experimental site during adzuki bean cultivation. As the soil moisture content increased, most of the adzuki bean cultivars showed deceases in stem height, first setting pod node, number of pods, 100 seed weight, and yield. Chungju-pat produced the greatest yields among the 11 cultivars in 2015 and 2016, whereas Hongeon had the smallest yields. Adzuki bean yields after paddy field cultivation was lower for all cultivars than for adzuki bean yields from the same cultivars after upland field cultivation. Chungju-pat and Chilbo-pat showed the smallest decreases in yields after paddy field cultivation, whereas Hongeon and Kumsil showed the greatest yield reductions. There were no significant differences in proximate composition. Some mineral components (P2O5, Ca, and Mg) were statistically different across cultivars. Chungju-pat had the highest Ca and Mg contents, but antioxidant components (polyphenol and flavonoids) and antioxidant activities (ABTS and DPPH) were highest in Saegil and lowest in Jungbu-pat. PCA and clustering analyses, based on the growth, yield, and antioxidant component measurements, performed to identify which variables contributed the most to separating adzuki bean cultivars or to grouping cultivars with similar characteristics. These analyses showed that the antioxidant components and antioxidant activities had the most influence on grouping cultivars together. Among the 11 cultivars, Saegil was statistically different from the other cultivars, but the other 10 cultivars were not significantly different under paddy field cultivation. Soil moisture content affected adzuki bean yield and antioxidant component contents. An increase in soil moisture led to a decrease in yield, but an increase in antioxidant components. These results provide information that will improve the selection of an appropriate adzuki bean cultivar for use in paddy fields.

        Background : This study was conducted to investigate the antioxidant activities and anticancer effect in 80% ethanol extract from foxtail millet (Setaria italica) and proso millet (Panicum miliaceum) and sorghum (Sorghum bicolor) varieties. Methods and Results : These extracts were evaluated for contents of total polyphenol and antioxidant activities using DPPH and ABTS radical scavenging activities. In concentration of 1000 ㎍/㎖, total polyphenol contents of foxtail millet, proso millet and sorghum were 7.68 - 12.74 ㎍․GAE/㎖, 13.01 - 14.79 ㎍․GAE/㎖ and 48.24 - 62.33 ㎍․GAE/㎖, respectively. Sorghum extracts showed strong radical scavenging activity comparable to well-known antioxidant, trolox. Anticancer effect was evaluated for MTT assay using AGS human gastric cancer cells. All extracts decreased growth of AGS cancer cells. Foxtail millet extracts were decreased about 40% of cell viability in all concentrations. Sorghum extracts were decreased cell viability, concentration dependent manner. Especially, Donganme extract (one of the sorghum variety) was the highest anti cancer effect under AGS cancer cells. Conclusion : Based on these results, millet and sorghum has potential health promoting bioactive compounds as functional food.
