  • To develop a new traditional Gugija tagju, various koji were prepared using several starch sources along with Aspergillus awamori var. kawachi, and then their effects on the quality of the tagju were investigated. Ethanol contents(11.1${\sim}$13.8%) were not significantly different among the Gugija tagju made from the various types of koji, whereas the tagju made using non-glutinous rice koji had the best total acceptability. The addition of 1% Gugija extracts into the mash increased its total acceptability and anti-hypertensive angiotensin I-converting inhibitory activity, and the optimal fermentation period for brewing the Gugija tagju was 10 days.

  • The list of monthly offering items of the Chunshin(薦新) ceremony, the service of offering the first food product of year to ancestors, shown in the Walryong(月令) in Oreaeui(五禮儀), the book written in early years of the Chosun dynasty, was studied and classified by food group. Six kinds of the cereals and grain products - barley, wheat, an early-ripening rice plant, a barnyard millet, and millet seed were offered. The meat products offered were wild geese, pheasants, swans, hares and dried-pheasants. Though not shown in e Walryong, roe deer and deer were offered from hunting trips in e winter. Eight kinds of sea-fish, six kinds of fresh-water first and six kinds of other seafood such as crab, octopus, and squid were offered. Ten kinds of vegetables: bamboo shoots, e99plants, cucumbers, etc. - were offered. Eleven kinds of tree fruits - cherries, apricots, Pears, etc., seven kinds of citrus fruits - tangerines, citrons, etc., seven kinds of nuts - chestnuts, pine-nuts, etc. and two kinds of melons - watermelons etc. - were offered. The hi인est variety in the offering items was the fruits category The remaining offering items included wine brewed from new rice. new brown seaweed, and green tea.

  • This study was carried out to compare the physicochemical characteristics and preference as a sensory quality of Sogokju (Korean traditional rice wine) from waxy rice varieties. The protein and moisture contents of milled waxy rice varieties were ranged 6.9~7.2% and 12.1~ 12.6%, respectively. Nunbora had the largest grain size. In pasting properties, Hangangchalbyeo had the highest peak, trough and final viscosities, and Dongjinchalbyeo had the lowest viscosity curve. These differences suppose to be caused by the amylopectin(AP) structure: Dongjinchalbyeo has the largest short AP chains (degree of polymerization (DP) 6-12) and the smallest middle AP chains (DP 13-24) in 9 waxy rice varieties, while Hangangchalbyeo has the smallest short AP chains and the largest middle AP chains. The alcohol contents of Sogokju brewed from 9 waxy rice varieties were 17.6~19.9%. The brix degree were ranged $20.5{\sim}23.9^{\circ}Bx$. The organic acid of Sogokju consisted mainly of succinic acid, and the free sugar of it consisted mostly of glucose. The sensory evaluation showed the highest palatability at the Sogokju from Baegseolchalbyeo. The palatability was positively correlated with the brix degree, the glucose content, and the turbidity, and negatively correlated with the production yield of Sogokju.

  • Rice vinegar (RV) is primarily made from fermented rice or rice wine in Korea, China, and Japan. Ten commercially available naturally-fermented rice vinegars produced in Korea (KRV1~4), China (CRV1~2), and Japan (JRV1~4) were comparatively investigated for their physicochemical properties and antioxidant activities. KRV showed a significantly higher total acidity range (5.07~6.27) than both CRV (4.67~4.84) and JRV (4.64~4.84). These acidity ranges corresponded with respective standards of each country: Korea (Food Code), China (GB), and Japan (JAS). Six different organic acids were detected in RVs; acetic acid and succinic acid were the most prominent. Thirty different amino acids were detected in RVs, and main identified amino acids were alanine (KRV), phenylalanine and aspartic acid (CRV), and leucine and alanine (JRV). ${\gamma}-Aminobutyric$ acid was detected at high concentration in KRV1. KRV1 showed maximum total phenolic content, and DPPH and ABTS radical scavenging activities of samples were also determined with significantly increasing tendency. KRV1 (produced from brown rice with aging period of >1 year) exhibited the highest free amino acid content and antioxidant activity as compared to CRV and JRV.

  • A new strain of acidophilic, acetogenic bacterium, Acetobacter sp. strain HA was isolated by selective enrichment from the traditionally fermented rice wine vinegar in Korea. It was a gram-negative, non-motile short rod and oxidized acetate and lactate. The optimal temperature and pH for growth were $28^{\circ}C$ and 4.0, respectively. The strain HA differed from other Acetobacter species by growing well on methanol, xylitol, inositol, dulcitol, D-xylose, L-arabinose, and D-mannose as sole sources of carbon and energy. The isolated strain HA did not produce $\gamma$-pyrones from glucose and did not produce ketone bodies from glycerol. The quinone system used in this study was an ubiquinone-9 isoprene unit. The guanine-plus-cytosine content of the DNA was 50.7 mol%, and the major cellular fatty acids were $C_{18:1} and C_{16:0}$.

  • A ${\beta}$-glucosidase producing yeast strain was isolated from Korean traditional rice wine. Based on the sequence of the YCL008c gene and analysis of the fatty acid composition, the isolate was identified as Saccharomyces cerevisiae strain HJ-014. S. cerevisiae HJ-014 produced ginsenoside Rd, $F_2$, and compound K from the ethanol extract of red ginseng. The production was increased by shaking culture, where the bioconversion efficiency was increased 2-fold compared to standing culture. The production of ginsenoside $F_2$ and compound K was time-dependent and thought to proceed by the transformation pathway of: red ginseng extract ${\rightarrow}Rd{\rightarrow}F_2{\rightarrow}$ compound K. The optimum incubation time and concentration of red ginseng extract for the production of compound K was 96 hr and 4.5% (w/v), respectively.

  • Folk Remedies symbolize the medical art of the common people, and contain their special emotion and colloquial expressions. They are medical treatments in which the medical history and the tradition and the soul of a people are incorporated. They are handed down in various ways. This study introduces some of folk remedies. For example, powder of tigers' bones heals neuralgia. Rice wine brewing up with ginger is effective in a cold. Water boiling with safflower does good in neuralgia. Pasting herba houttuyniae takes effect in skin disease. To Decoct and drink old hardy orange is effective in urticaria. Water boiling with fructus corni alleviates a fever. Camellia oil or rhizoma cnidii or iris is used for the extermination of vermin and the antiseptic. In the end, the practical application of these remedies to the resources of industry and education will be discussed.

  • The Posuk-Chung Pavilion if a defunct irregular stone water channel in Kyongju, Korea, once used for the meandering stream feast'by kings of Silla Dynasty during the first millennium. The poets were seated around this stone water channel who composed the Chinese poems, overlooking the streams. They load to take the punishment drinks unless they finished the poem before the drifting cup filled with the rice wine arrived at their seats on the meandering stream. In this paper, we have made computer simulation as well as well as model experiment on the ancient meandering stream of the Posuk-Chung Pavilion. The computational results are compared with the experiment and the channel flow characteristics are delineated here. It is discussed how the present Posuk-Chung channel is morphologically distinguished from the Chinese and Japanese meandering streams.

  • A. oryzas 의 밀가루 누룩과 R. japonicus의 밀가루 누룩으로 탁주를 제조할 때에는 두 누룩의 혼합 비율이 탁주의 품질에 미치는 영향을 알아조기 위하여 두 누룩의 혼합 비율을 달리하여 7종의 탁주시료를 제조하고, 탁주의 이화학적 및 관능적 특성들을 조사하였다. R. japonicus는 누룩의 사용 비율이 높을 때에는 술덧의 산도와 유리당 함량이 높았고, 제성주의 부유물 함량과 부유물의 현탁 안정성도 높았다. 그러나 A. oryzas 누룩의 사용 비율이 높을 때에는 술덧의 산도와 유리당 함량이 낮았고, 제성주의 부유물 함량과 부유물의 현탁 안정성도 낮았다. R. japonicus 누룩과 A. oryzas 누룩을 2 : 1~5 : 1의 비율로 병용했을때에는 주박의 양이 크게 줄어들었고, 아미노산 함량이 증가하였으며, 기호성도 더 좋아졌다. 탁주의 전반적이 특성으로 볼 때 각 누룩의 단용시에는 R. japonicus 누룩이 A. oryzas 누룩보다 좋았다. 그러나 R. japonicus 누룩과 A. oryzas 누룩을 병용했을때에는 탁주의 전반적인 품질이 더욱 개선되어졌는데, 이때 두 누룩의 최적 혼합 비율은 대략 5 : 1이었다.
