The study was conducted to investigate some grain quality characters related with brewing fittness for rice wine by adopting eight rice varieties as materials. Six japonica rice varieties except two Tongil-type rice had short and round grain of 1.80 or lower grain length/width ratio. 1000-grain weight of brown rice was 21.7~29.5g of significant difference among varieties. The white-center of rice grain was most severe in Hidahomare and Iri 402. Among tested varieties, Seomjinbyeo, Iri 402, Dongjinbyeo and Hidahomare had 50% or higher head rice ratio, while the others had relatively worse milling properties resulted from higher ratio of notched-belly and broken grain. Chemical components and total acid and amino acid content of refined rice wine was relatively good in every variety. Liquifying and saccharificating power was higher and koji conditon was also good in the varieties of high head rice ratio. Seomjinbyeo, Dongjinbyeo and Iri 402 was preferred in sensory test of refined wine and was recognized as superior adaptable rice varieties for brewing rice wine.

제주민속주인 좁쌀약주의 제조를 위하여 전국에서 수집된 35종의 누룩으로부터 분리하여 선발한 균주를 사용하여 균주와 원료배합비율에 따른 누룩을 제조한 후 양조과정에서의 발효특성을 검토하였다. 좁쌀주의 유기산 및 유리당의 분석결과 유기산은 lactic acid와 acetic acid가 대부분이었고, 이외에 citric acid, oxalic acid, tartaric acid, malic acid, fumaric acid도 일부 검출되었다. 유리당은 glucose와 arabinose, maltose가 많은 함량을 나타내었고, 이외에 xylose도 일부에서 검출되었다. 향기성분은 i-amyl alcohol, i-butyl alcohol, n-propyl alcohol 등이 주를 이루고 있었으며, 이외에 ethylacetate, acetaldehyde가 검출되었다. i-buthyl alcohol과 n-propyl alcohol은 대조구인 Dl이 다른 처리구보다 높게 나타났고, i-amyl alcohol은 K5 처리구가 높게 나타났다. 본 연구를 통하여 우수균주로 분리하여 제조한 누룩을 사용하여 좁쌀주를 양조하는 경우, 품질을 유지하면서 수율을 향상시킬 수 있었다.

Antioxidative characteristics of freeze dried soybean sauce powder (SSP) on the oxidation reaction of linoleic acid mixture(LA) were evaluated by the determinations of peroxide formation, synergistic property, hydrogen donation and lipoxygenase activity. SSP was found to possess a considerable potentiality of antioxidant activity on the formation of hydroperoxides in the LA oxidation reaction system at $50^{\circ}C$ for 144hrs. This antioxidative effect was increased by the concentration from 0.02% to 0.5% of SSP in the reaction system. Under the condition of presence of ferric chloride (10 ppm) in the reaction system. appreciable effect of SSP on the synergistic antioxidation were observed. On the other hand, hydrogen donation property of SSP onto ${\alpha},\;{\alpha}'-diphenyl-{\beta}-picrylhydrazyl$ was found and inhibitory ability of SSP on LA oxidation was also shown in the reaction system of lipoxygenase-catalized oxidation.

Fermented soybean sauce was fractionated by gel filteration chromatography and the physico-chemical properties of each fraction were investigated for the study on the separation and characteristics of antioxidative substances in the soybean sauce. The brown coloured melanoidin fractions(MF-I) collected by Sephadex G-10 column were found to contain nitrogeneous compounds and to have strong antioxidative activity and reducing power. The freeze dried MF-I was further fractionated with Sephadex G-50 and G-100 successively and then MF-II and MF-III fractions were observed to be the most effective antioxidant and reducing power among the fractions. The UV-VIS and IR absorption spectra of the each fraction were also determined and discussed.

In order to improve the quality of foxtail millet wine, zymological properties by isolated strains from Nuruk were investigated. Saccharomyces sp Y5-1 as brewing yeast, Aspergillus sp. M6-3, Aspergillus awamori 6970, and Aspengillus usamii mut. shirousamii 6959 (KCTC) as saccharifying molds were used, respectively. Acid content, soluble solids, color (b) and alcohol contents were increased during fermentation. Ethanol concentration of millet wine made with Nuruk by Aspergillus awamori 6970 and Aspergillus usamii mut. shirousamii 6959 were higher than the other, 10.6 and 10.1% respectively. Citric acid was only detected on $1{\sim}2$ day starting fermentation. Oxalic acid, lactic acid and acetic acid of millet wine were high in the wine made of Nuruk by Aspergillus usamii mot. shirousamii 6959, Aspergillus awamori 6970 and traditional Nuruk, respectively. During fermentation, glucose and xylose was higher than the others. Xylose was increased, but most of other sugar were decreased during fermentation. Acetone, ethyl acetate, methanol, ethanol, n-propanol, iso-buthanol and iso-amyl alcohol were detected In the wine made with Nuruk by Aspergillus awamori and Aspergillus usamii mut. shirousamii, iso-imyl alcohol and ethanol were high. On sensory evaluation, the wine made with Nuruk by Aspergillus usamii mut. shirousamii was the best on color and taste.

This study aimed to evaluate quality characteristics of soy sauce by various manufacturing methods. We examined color values, contents of saccharide and free amino acid. Regarding color values, brewed soy sauce showed lower level of L-values than traditional soy sauce, and the L-value was increased with time dependent manner in traditional soy sauce. The one year old traditional soy sauce exhibited the lowest a-value whereas the three years old traditional soy sauce showed the highest b-value (+4.27). The content of the bitter and savory taste amino acids was the highest in commercial soy sauce with the values of 28.98% and 18.93%, respectively. In addition, traditional soy sauce contained more GABA than brewed soy sauce.

우리의 전래 민속주는 중국 둥과 같이 곡류 위주의 양조방식으로 발달하여 고대에는 그 기술이 일본 등에 전수될 정도로 선도하였으나, 조선말을 전후한 역사적인 시련기 속에서 별다른 개발을 보지 못한 가운데 서구적인 문명의 영향을 받아들이게 되면서 민속고유주의 개발 내지 재현보다는 서구적인 양조방식 혹은 외래주류의 모방 및 개발에 역점이 주어지고, 원료면에서 식량자원의 제한에 따라 많은 제약을 받아오면서부터 그 쇠퇴일로를 거듭하였다. 따라서 우리의 전통 민속주류의 올바른 복원과 현실화를 위한 체계적인 연구가 우선 중요한 과제로 대두되고 있다.(중략)
