  • Soy sauce, a basic ingredient in Asian cuisine, is made of fermented soybeans, salt, water, and barley or wheat flour. The sensory characteristics of soy sauce are not only determined through its main ingredients but also by various flavor compounds produced during the fermentation process. This study was conducted to identify the sensory attributes of five different commercial soy sauce samples that differ in Meju types (traditional Meju or modified Meju) and usage types. Thirty three sensory attributes, including appearance (1), odor (16), flavor (14), and mouthfeel (2) attributes, were generated and evaluated by eight trained panelists. The collected data were analyzed by analysis of variance and principal component analysis. There were significant differences in the intensities of all sensory attributes among the soy sauce samples. Soy sauce made with traditional Meju had high intensity of fermented fish, beany, musty odors and salt, Cheonggukjang, fermented fish flavors. Whereas two soy sauces made with modified Meju were strong in alcohol, sweet, Doenjang, roasted soybean flavors. Two soy sauces for soup made with modified Meju had medium levels of briny, sulfury, fermented odors and bitter, chemical flavors and biting mouthfeel characteristic.

  • Flavor components in mash of Takju prepared by different raw materials such as nonglutinous rice, glutinous rice, barley and wheat flour were detected by GC and GC-MS method using non-polar column. Seven alcohols, 15 esters, 10 organic acids, 1 aldehyde, 4 benzenes, 3 phenols, 8 alkans, 2 ketones and 5 others were found in takju after 16 day of fermentation. takju by wheat flour had the most various components of volatile flavor. Treatment with addition starter had less flavor component than that without addition starter in takju by nonglutinous rice. Nine kinds of flavor components including acetic acid ethyl ester, 3- methyl-1-butanol, acetic acid, ethyl benzene, acetic acid 3-methyl butyl ester, 2-phenylethanol, 2,6-di-tert-butyl-4-methyl phenol. plumbagic acid and 1,2-benzenedicarboxylic acid dibutyl ester were commonly detected in all the treatments. Especially, 2,4,0-trimethyl-1,3-benzenediamine was isolated in takju that was made of nonglutinous rice without addition starter. Diethyl sulfide, 4-methoxy benzaldehyde, docosane and 2-methyl propyl octadecanoic acid were isolated from takju by nonglutinous rice with addition starter. Propionic acid ethyl ester, acetic acid butyl ester, 2-methyl butane and 3-methyl pentane were isolated from takju glutinous rice. 2-Hydroxy-4-methyl pentanoic acid and 2-methyl tridecane were isolated from akju by barley 3-(Methylthio)-1-propanol. hexanoic acid ethyl ester, butanoic acid monomethyl ester, tridecanoic acid, ethyl tetramethyl cyclopentadiene and 1,5-diaza-2,9-diketocyclotetradecane were isolated from takju by wheat flour. Major volatile flavor components were acetic acid ethyl ester, 3-methyl-1-butanol, acetic acid and 2-phenylethanol.

  • To determine the effect of soil moisture stress on growth of barley and grain quality, a pot experiment was carried out for two barley varieties(Olbori and Chogangbori) by using large plastic pot(52cm in diameter and 55cm in depth) filled with sandy loam soil under rain-controlled open green house. By means of measuring soil water potential with micro tensiometer and gypsum block installed at 10cm in soil depth, soil moisture was controlled by sub-irrigation at several irigation points such as -0.05bar, -0.2bar, -0.5bar, -1.0bar, -5.0bar and -10.0bar in soil water potential. The lower soil water potential was controlled, the shorter length of stem and internode became, and the more narrow stem diameter was. Leaf area was significantly decreased when soil water potential was controlled lower than -0.5bar, although chlorophyll content of flag and first leaves was not changed so much. Weight of grain and ear was significantly decreased when soil water potential was lower than -5.0bar and the highest grain yield was obtaind in a plot where soil water potential was controlled at -0.2bar. However, the most efficient water use of Olbori and Chogangbori was obtained at -0.5bar and -1.0bar in water potentials, respectively. Crude protain content, maximum viscosity, consistency and ${\beta}$-glucan content of barley flour increased as soil water potential significantly decreased, especially below -5.0bar, but gelatination temperature decreased as soil water potential decreased.

  • Varieties of the cereals produced in the Biblical times and the ways these cereal foods have been grafted into Korean food culture has been pursued, and the regulations of agricultural life and the metaphors or parables of cereals represented throughout the Bible have been studied. The word "grain" appears eight times in the KJV and one hundred seventeen times in the RSV. On the other hand, the word "corn" shows up one hundred and one times in the KJV but not in the RSV at all. Wheat, one of the earliest cultivated and the most important grains for food is mentioned fifty two times in KJV and generally the rich in those days lived on wheat in the parched state or in the form of bread. Barley, one of the staple cereal crops of Palestine is referred to thirty six times in the KJV. It was less expensive than wheat and so was used mainly for the food of such animals as horses, donkeys and cattle, but sometimes it was mixed with flour and used for making bread for men, mostly for Poor men. The spelt (in ASV and RSV) and the rie(in KJV) appearing in Exodus 9:32 is a kind of grain, which is translated into Na-mack (in Hangul Revised Bible ; HRB), Ssal-bori (in Hangul Common Translated Bible : HCB) and Ho-mil (in Hangul King James Bible; HKJB) but which should be put into Spelt-mil in Korean. The lentil appearing in Genesis 25 : 34 is translated into Pat (red-bean) and Bul-kong respectively in HRB and HCB but the same word in the Second Book of Samuel is translated into Pat in both HRB and HCB. HCB translates lentil into Bul-kong in Genesis and into Pat in the Second Book of Samuel (23:11). HCB and HKJB which put lentil into Pat in previous parts translate the word into Nok-tu in the Second Book of Samuel. The word, lentil here should be put into lentil-kong and parched pulse into "Poken-Chong-ja" not into Poken-Nok-tu. Millet which is translated into Cho should be put into Gui-jang. filches should not be classified as a grain or a cereal but as a flavor or a condiment, so the word filches should be put into So-Hoi-hyang or Hoi-hyang. Regulations in reference to agriculture are included in the Bible. That is, it is seen that the Bible regulates the observance of the sabbatical year and feasts, the partition of land, how to sow and so on. It is also observed that grains are used for metaphors or parables: wheat represents the peaceful times and straws are compared to trifles. As seen above, there should be more prudent examinations and standards for the translation of grains into Pat, Pul-kong, Nok-tu, Gui-ree, Ssal-bo-ri and Na-mack.i-ree, Ssal-bo-ri and Na-mack.

  • Buckwheat often causes severe allergic reactions in sensitive people. One of the major allergenic proteins in common buckwheat (Fagopyrum esculentum) has been found to be a BW10KD protein. In this study, we developed a PCR method to detect buckwheat ingredients in food using primers corresponding to the allergenic BW10KD gene. Five pairs of oligonucleotide primers successfully enabled PCR amplification of the specific regions of the genomic BW10KD DNA from buckwheat, but no amplification from seven other cereals and beans (barley, wheat, German millet, African millet, soybean, red bean, and black bean). The proposed PCR method was applied to analyze 12 processed foods (buckwheat flour, buckwheat noodle, buckwheat jelly, wheat noodle, instant noodle, black sesame gruels, sunsik, cookie, misutkaru, and three kinds of cereal); among them, only three samples including buckwheat flour, buckwheat noodle and buckwheat jelly showed a positive reaction to the detection. This PCR method was able to detect as little as 1 ng of common buckwheat DNA. This rapid and specific PCR method would be applicable to detect allergenic buckwheat ingredients in food.

  • In this study, we aimed to develop mixed grain-derived hard liquor with enhanced favor and taste. First, fermentation characteristics analysis according to the grain used showed that rice and adlay produced high alcohol outputs of 15.2% and 13.3%, respectively, while that of barley was low at 5.6%. In an experiment in which different amounts sorghum flour were added, the sample without sorghum flour showed an alcohol content of 19.0%. The effect of adding up to 7% ipkuk (koji) was examined in a sensory test. Comprehensive preference increased with increasing amounts of added ipkuk. Fermentation characteristics analyses of distilled liquor into which milled rice (5% degrees of milling of unpolished waxy rice) was added showed that alcohol content and acidity were not greatly affected by its addition. Finally, an analysis of aromatic ingredients showed that the percentage of ethyl palmitate, which produces a smooth aroma, was the highest in distilled liquor made of mixed grains.

  • In order to improve foxtail millet wine, a traditional Jeju cereal wine, fermentation characteristics of millet Yakju with different types of Nuruks prepared using isolated Aspergillus sp. and Rhizopus sp. were investigated. When the millet wine was brewed with the Nuruk prepared in this study, the combination ratio of wheat flour: barley : wheat bran : millet = 8 : 1 : 1 : 0 (pellet) showed the highest level of alcohol concentration, and a more favorable score than Kuksundang Nuruk in sensory evaluation. The main organic acids in millet wine were lactic and acetic acids, and the minor organic acids were fumaric, oxalic, citric and malic acids. Analysis of sugar compositions showed that glucose, arabinose, and maltose were present in decreasing order, and that xylose was also detected. Flavor components of millet wine were mainly iso-amyl, iso-butyl and n-propyl alcohols. Ethylacetate and acetadehyde were also detected. The contents of iso-butyl and n-propyl alcohols were higher in the millet wine prepared with Kuksundang Nuruk than those prepared with other Nuruks.

  • The present study was performed to investigate the effect of cereal fiber on lipid concentration of liver and serum in rats. Male Sprague-Dawley rats weighing 180$\pm$4g were divided into five groups by completely randomized block design : R, BR, B, W, and F. Each group fed a diet containing 0.7% cholesterol and a kind of cereal among rice(R), brown rice(BR), barley(B), whole wheat(W), and wheat flour(F) for 5 weeks. The results were summarized as follow : 1) Food intake. weight gain and feed efficiency ratio were not significantly different among the groups. 2) Fecal wet weight and dry weight were significantly higher in W group which fed the most amount of IDF(insoluble dietary fiber). 3) The weight of large intestine was significantly heavier in the W group compared to the others. But the weights of liver, stomach and small intestine were not significantly different among the groups. 4) Total lipid. triglyceride(TG) and total cholesterol(TC) content in liver were significantly different among the groups. The values were the lowest in the B group whose intake of SDF(soluble dietary fiber) was the highest 5) TC content in serum was not significantly different among the groups. TG content in serum was significantly lower in the rest groups than in the R group. HDL-c and free-c content in serum were significantly higher in the B group than in the rest groups. HDL-c/LDL-c, free-c/ester-c ratio were the highest in the B group but not significant. Above results show that the dietary fiber contained in cereals has physiological effects and they are different depending on fractions, IDF and SDF.

  • The change in the police concerning food and dietary life were analyzed in order to provide bases of establishing policy of food and dietary life properly. The last half one century was divided into six periods as follows ; The period since liberlation from Japanese rule(1945-1949) the 1950's (1950-1959) 1960's (1960-1969) 1970's (1970-1979) 1980's (1980-1989) 1990's (1990-1992). Dietary life by 1960's were a life of distress and policies coducted by government took on an relief supply of food at this period. Movement about 'intake of mixed rice with barley and foods from flour' to supress rice consumption were encouraged by government. And Korean recommended dietary allowance was made and the national nutritional survey was practived in the first place by the Ministry of Health and Social Affairs. Dietary life of the country begin to improve sharply along with rice self-sufficiency since 1975 With the growth of food and eating out industry intake of instant food processed food and fast food has increased at the 1980's To ministry of Health and Social Affairs drove campaign of 'Joo-Moon Sik Dahn Je' for dietary life improvement at 1981 The Ministry of Education made and announced a 'School Feeding Law' at 1981 The government that is the Office of Permier and the Ministry of Health and Social Affairs developed compaign for improvement of dietary life and drove 'Jo Eun Sik Dahan Je' with Association of restaurant jointly. Policy on food and dietary life conducted by government up to data were planned mainly dependent on food production supply and demand of food. Infectious diseases continue to decrease with increasing of degenerative diseases which will be required proper management of dietary life. In the future more aggressive intergrated food policy are needed to maintain the public health. Aoso dietary improvement movement should be drived actively.
