  • The analytical method for bifenazate was developed using a HPLC (UVD). Also, analytical condition of LC/MS was set up for bifenazate. We validated the method for the precision and the reproducibility. The correlation coefficient of bifenazate ranged from 0.05 to 2.5 mg/kg was 1.0. Limit of quantitation (LOQ) was 0.01 mg/kg. To measure recoveries from agricultural products such as foxtail millet (cereal grains), kidney bean (beans), orange (fruits), perilla leaves (vegetables) and oak mushroom (mushrooms), bifenazate was spiked. Mean recoveries of bifenazate for each sample were 82.7~104.1% at the level of 0.1 mg/kg and 73.1~104.3% at the level of 0.5 mg/kg. The relative standard deviations (n=3) were 0.2~9.7%. Pesticide residues for bifenazate were investigated in 16 commodities (rice, foxtail millet, buckwheat, kidney bean, peanut, sesame, orange, grapefruit, kiwifruit, spinach, perilla leaves, leek, garlic stem, garlic, ginger and oak mushroom) collected from 22 provinces in 2009. Bifenazate was analyzed using analytical method by HPLC from 304 samples, and residue was not detected.

  • In order to compare the anti-inflammatory effects of five selected cereal grains-proso millet, hwanggeumchal sorghum, foxtail millet, barnyard millet, and adlay-the inhibitory activities of 80% ethanol (EtOH) extracts obtained from the individual grains on lipopolysaccharide (LPS)-induced nitric oxide (NO) generation were investigated in RAW264.7 cells. The EtOH extract of barnyard millet (Echinochloa crus-galli var. frumentacea) grains exhibited more potent anti-inflammatory activity than that of the other grains. When the EtOH extract of barnyard millet grains was sequentially fractionated with n-hexane, methylene chloride (MC), ethyl acetate (EtOAc), and n-butanol, the majority of the anti-inflammatory activity was detected in the MC fraction, followed by the EtOAc fraction. Pretreatment with the MC fraction caused downregulation of the expression levels of iNOS- and COX-2-specific transcripts and proteins, as well as proinflammatory cytokine gene transcripts (IL-$1{\beta}$, IL-6, and TNF-${\alpha}$) in LPS-stimulated RAW264.7 cells. Additionally, the MC fraction could suppress not only the LPS-induced nuclear translocation of cytosolic NF-kB, but also the LPS-induced activation of MAPKs, such as ERK, JNK, and p38MAPK. Further analysis of the MC fraction by HPLC identified kaempferol, biochanin A, and formononetin as the major phenolic components. Both kaempferol and biochanin A, but not formononetin, could exert anti-inflammatory effect at the same concentrations as those of the MC fraction. Consequently, these results indicate that kaempferol and biochanin A are among the most effective anti-inflammatory phenolic components in barnyard millet grains. This finding suggests that barnyard millet grains and the MC extract enriched in kaempferol and biochanin A could be beneficial functional food sources that have an anti-inflammatory effect.

  • This study was designed to determine blood glucose responses to some cereals produced in Korea. The levels of blood glucose were measured over 2 hours after feeding healthy vounteers with 50g carbohydrate portions. The glycemic index(GI)k and glycemic index-rice(GI-rice) of a food has been defined as : GI=mean of (blood glucose response area of test food/ blood glucose response area of glucose taken by the same indicidual) $\times$100 and GI-rice=mean of (blood glucose response area of test food/blood glucose response area of rice taken by the same individual) $\times$100. The area under the curve is taken to be the area above the fasting value calculated geometrically from blood glucose increments. The GI of barely to glucose as the standard(57$\pm$7) was significantly (p<0.05) lower than those of other cereals whereas the GI of glutinous rice (110$\pm$8) was significantly (p<0.05) higher than other those of cereals. The GI values to rice as the standard were 63 $\pm$6 for barley, 79$\pm$5 for buckwheat, 85$\pm$6 for foxtail millet, 90$\pm$12 for unpolished rice, 100$\pm$0 for rice, 102$\pm$7 for glutinous rice, 106 $\pm$6 for unpolished glutinous rice, 115$\pm$13 for glutinous millet, 116$\pm$13 fro job's tear, and 122 $\pm$ 4 glutinous sorghum. The mean GI-rice was identical to the mean of the adjusted GI values, with a correlation coefficient of r=0.964(p<0.0001). This finding suggests that white rice could be used as standard food for the determination of GI.

  • Imwonshibyukji was a copying manuscript written around 1825, the 27th year of king Soonjo of the Josun Dynasty. It was a massive home encyclopedia of total 52 books and 100 volumes. The unpublished 'Jeongjoji' of its 17-20th volumes analyzed the cooking methods on the steamed rice and gruel and studied the degree of their usefulness and medical values in the light of the cooking process science. The cooking method on the steamed rice was composed of 14 items, and the general introduction outlined 6 kinds of the rice. These were all quoted from Chinese literatures. The 11 items present the methods on the general production of the rice, 2 on the cooking process, and 1 on the preservation. The main material of the rice was rice, and others were naked barley, prosomillet, foxtail millet, glutinous millet, etc. , and the secondary materials were glutinous rice, small red bean, black soybean, potato, bamboo seed, jujube, taro, gaertner, chestnut powder, persimmon power, julib(Zizania caduciflora), mangcho(Erigeron canadensis), namchok(Nandina domestica), licorice root, nitrous, peach, palmicha(schizandra, jinseng, cheonmoondong(Asparagus), and honey are mixed), etc. The literatures quoted in the rice were all 33, in which 23 were Chinese (69.7%) and 10 were Korean (30.3%). In the case of gruel, the cooking methods on the general gruel were described in 41 items, and on the gruel for a medical treatment were in 48 items, in which there was not a cooking method on the gruel but only its medical values were presented. The materials used for the general gruel were approximately 60 kinds: rice, glutinous rice, munbean, job's tears, rye, soybean, black sesame seed, antler of cervidae, chicken, crucian carp, and various medical materials, etc. The gruel was mainly used for protection and medical treatment, and partly for food for hungry people. The literatures quoted in the gruel were total 57, in which 26 were Korean(45.6%), and 31 were Chinese (54.4%). It can be their characteristics that Almost all of the Chinese literatures on the methods of the steamed rice and gruel do not exist.

  • This study investigated the changes in physicochemical characteristics after 120 days of aging Korean red pepper paste, 'Kochujang', made of minor cereals in substitution for glutinous rice which has been conventionally used as starch source. The cereals used were waxy job's tears, proso millet, sorghum, barley and foxtail millet, Glutinous rice with barley was used as controls. The items determined were water activity, pH, content of amino nitrogen, chromaticity and sensory test. 1. The water activities(Aw) of Kochujang samples were in range of $0.72{\sim}0.82$ at the beginning of fermentation, with Aw barley paste bing the lowest, and Aw of sorghum paste bing the highest. Then Aw were slowly decreased to the range of $0.49{\sim}0.50$ during 120 days of fermentation 2. The pH of the pastes was in range of $4.94{\sim}5.02$ at the initial time of fermentation, and decreased steadily to 4.32{\sim}4.73 at the end. 3. The content of amino nitrogen was in range of $330.9{\sim}340.7\;mg%$ at the early time of fermentation. The highest content, $351{\sim}381\;mg%$, was observed at the 90th day of aging of glutinous rice paste, 105th day of job's tears paste, 75th day each of barley and proso millet, and 60th day each of sorghum and foxtail millet. 4. The Hunter tristimulus values (L, a, b) of all pastes were gradually decreased during fermentation. The value of barley paste was lowest among the pastes. 5. The texture of barley paste in sensory test showed significant difference with other pastes, whereas there were no differences in color, odor, taste and sensory qualities.

  • Acidovorax avenae subsp. avenae is the causal pathogen of several hosts including oats corn foxtail millet wheatgrass sugarcane and rice. The pathogen is a seedborne pathogen of rice and known to occur widely in rice growing countries. The pathogen cause inhibition of germination brown stripe on the leaf curling of the leaf sheath and abnormal elongation of the mesocotyl of irce. Bacterial colonies grow slowly and are convex circular and creamy with tan to brown center. The causal baterium is Gram-negative and rod shape with a single polar flagellum Nonfluorescence poly-$\beta$-hydroxybutyrate accumulation and precipitate formation around the colony on the medium are useful in the differentiation of this bacterium from other subspecies of A. avenae as well as nonfluorescent bacteria pathogenic to rice. This bacterium has belonged to the genus of Psdeudomonas but recently was transferred to the new genus Acidovorax on the basis of bacteriological and molecular biological data. However the difference of biochemical characteristics protein profile of the cell and host range among strains should be more clarified. To develop an effective control strategy for this disease understanding of detailed life cycle of the disease ritical environmental factors affecting disease development on each host and relationship to grain discoloration of rice are prerequisite. Although the affected area has been world-widely reported there is on recent progress on the understanding of the bacteriological and ecological characteristics of the causal bacterium and control means of the disease.

  • The objective of this study was to improve the qualities of Saengsik (substitute meal formulated with uncooked cereal powder) such as functionality, safety and sensory preference by using Lactic Acid Bacteria (LAB). The optimum formulation of fermented Saengsik (substitute meal) was verified as $40\%$ of fermented brown rice, $13\%$ of fermented job tears, $5\%$ of yellow soybean, $5\%$ of waxy rice, $5\%$ of sorghum, $3\%$ of Seumok bean, $1\%$ of sesame, $3\%$ of barley, $2\%$ of red bean, $5\%$ of prosomillet, $2\%$ of foxtail millet, $9%$ of black rice, $3\%$ of buckwheat, $1\%$ of chestnut, $2\%$ of pumpkin, $3\%$ of peanut. Fermented Saengsik decreased significantly serum glucose in STZ-induced diabetic rats. However, serum lipid levels were not affected by fermented Saengsik. In rats fed with high-fat diet, serum triglyceride level was slightly decreased and the contents of liver triglyceride were significantly decreased by supplementation of fermented Saengsik.

  • In this treatise, we investigated the Korean literature of main dishes before the 17th century : ${\ulcorner}Sangayorock{\lrcorner}$, ${\ulcorner}Sasichanyocho{\lrcorner}$, ${\ulcorner}Soowonjabbang{\lrcorner}$, ${\ulcorner}Yongjechongwha{\lrcorner}$, ${\ulcorner}Dongyoebogam{\lrcorner}$, ${\ulcorner}Domoondaejak{\lrcorner}$, ${\ulcorner}Geebongyouseul{\lrcorner}$, ${\ulcorner}New-Guwhangchalyo{\lrcorner}$, ${\ulcorner}Eumshickdimibang{\lrcorner}$,, ${\ulcorner}joobangmoon{\lrcorner}$, and ${\ulcorner}Yorock{\lrcorner}$. Main dishes were classified 19 kinds of rice, 64 kinds of gruel, 6 kinds of thin gruel, 1 kind of Moori, 1 kind of rice-cake soup, 37 kinds of noodles and 20 kinds of dumpling. Rice varieties were brown rice, rice, hulled rice, millet rice, foxtail millet rice, barley rice, sesame rice and flax seed rice. Gruel ingredients were cereal, beans, vegetables, nuts or seeds, medical plants or hardy wild plants, poultry, pork's kidney, dog's liver or oyster, clam and/or milk Rice-cake soup was 'Tangbyun' in ${\ulcorner}Domoondaejak{\lrcorner}$. Noodles were divided by main flours: wheat flour, buckwheat flour, mung bean flour and other flours. Noodles were made by pressing or cutting method. Pressing method used a mold with a hole. The husk of dumpling was made by wheat flour, buckwheat flour, mixed flour of wheat and buckwheat, sliced fish or meat, and/or a gray mullet. Another special method was 'Sangwha' made by fermentation. Bun stuffing of dumpling used fishes, meat, vegetables, beans, flours and seasonings. Cooking methods of dumpling were boiling, baking, steaming and pan-frying. From this investigation of the Korean main dishes described in the Korean literature before the 17th century, we expect to develop useful recipes for those who are concerned about health and want longevity, and thereby to advance the Korean food culture.

  • This study evaluated the quality characteristics, the presence of polyphenolic compounds, and radical scavenging activity of rice cooked along with various mixed grains (barley, black soybean, adzuki beans, foxtail millet, proso millet, sorghum, glutinous rice) by following two different cooking methods (normal and pressure cooker). The amylogram and water characteristics of mixed grains showed significant differences based on the presence of different types of mixed grains. The chromaticity, palatability characteristics, presence of phenol compounds, and radical scavenging activity of rice cooked along with different mixed grains showed significant differences according to the nature of mixed grains. Total polyphenol contents of before cooking, cooked-rice added to mixed grains cooked in the normal cooker and a pressure cooker were 4.46~5.16, 0.58~0.93 and 0.65~0.96 mg GAE/g, and total flavonoid contents were 250.74~548.89, 129.26~207.04 and $127.41{\sim}218.15{\mu}g\;CE/g$, respectively. The DPPH radical scavenging activity of before cooking, cooked-rice added to mixed grains cooked in the normal cooker and a pressure cooker was 79.25~181.61, 22.07~53.64 and 7.51~39.97 mg TE/100 g, and ABTS radical scavenging activity was 203.25~328.24, 47.28~84.94 and 58.27~99.51 mg TE/100 g, respectively. Accordingly, it is necessary to different combinations of mixed grains according to the cooking method at home and grain industry.
