  • The aim of the sutdy is to collect a variety of wild yeasts from different regions in Korea and in different seasons and to account for the natural patterns of regional and seasonal variation that they display. From the specimens collected in this study, more useful strains are expected to be discovered, which can be cultivated and utilized fro industrial development. The study attempts to determine the degree to which utilizable yeasts can be applied in brewing, confectionary, baking, the manufacture of medicine, and as feed yeast. Such findings would contribute not only to the development of academic research, but would also be important in obtaining raw material that can be applied in our daily lives and in industrial development in response to the demands of the times.

  • To reproduce the brewing process of Hongkuk-ju and to identify the functional properties of it, Hongkuk-ju was brewed using different additions of Hongkuk (100%, 90%, 70%, 50%) and Nuruk (0%, 10%, 30%, 50%). The quality elements, including pH, total acidity, reducing sugar content, alcohol content and pigments (yellow, red, monacolin K and citrinin), were measured. The pH values of Hongkuk-ju showed a slight difference (pH 4.08~4.58) right after the $1^{st}$ stage mash; further, the pH on all groups (H1, H2, H3 and H4) in the terminal of the $2^{nd}$ stage mash (9 days in fermentation) were similar, ranging approximately at pH 3.70. The total acidity change did not show a difference directly the $1^{st}$ stage mash (nearby 0.2 %); however, it began to show a slight difference at the terminal of the $2^{nd}$ stage mash between the range of 0.69~0.76%. The residual reducing sugar of the content was decreased with the increased Nuruk content. The alcohol concentrations of the treatment brew with Nuruk ranging from 12.3% to 13.7% were higher than Hongkuk on its own. The yellow and red pigment contents of Hongkuk-ju ranged from 7.2~8.8 O.D. units (yellow pigment) and from 4.4~5.1 O.D. units (red pigment). The production of monacolin K and citrinin was the highest (9.48 mg/kg and 10.14 mg/kg) when the treatment solely brewed Hongkuk. The concentration of Nuruk and the preparation of the seed mash from it were critical factors compared to the treatment of rice in brewing Hongkuk-ju.

  • 최근 막걸리 소비량이 증가함에 따라 막걸리의 기능성 및 기호도가 증진되고 있어 막걸리에 석류의 기능성을 부여하고 색택을 향상시키고자 석류즙 농축액을 이용하여 석류 막걸리를 제조하였다. 막걸리 제조를 위해 첨가 시기 및 농축액 첨가량(3, 5, 7%)을 달리하여 석류 막걸리를 제조하였으며, 제조된 석류즙 막걸리의 이화학적 특성 및 관능평가를 실시하였다. 그 결과 석류즙 농축액 첨가량이 많을수록 적정산도, 당도, 알코올 함량은 높았다. 반대로 pH 아미노산 함량은 첨가량이 많을수록 낮았으며, 석류 막걸리의 관능검사 결과 3% 석류즙 농축액을 첨가한 처리구가 단맛, 신맛, 쓴맛, 향, 색감, 전체적 기호도에서 가장 높은 점수를 얻었으며 석류즙 막걸리를 위한 밑술 제조 시 3% 석류즙 농축액을 첨가하여 제조한 막걸리의 품질이 가장 우수하였다. 결과를 종합해 볼 때, 석류즙 농축액 3%를 밑술 제조 시 첨가하여 제조하는 것이 석류 막걸리의 제조와 제조된 석류 막걸리 제품화에 있어서 가장 우수할 것으로 판단된다.

  • This study delves into the general characteristics of spirits brewed in the Central Region of Korea-Seoul, Kyonnggi-do, Chungchung-do-paying particular attention to their varieties and fermenting methods and also comparing similarities and differences of their features. It is found first of all that there are a wide range of variety in the kinds of liquors. Among the 21 spirits investigated, not a single one resembles any one of the remaining in terms of the raw material, and the brewing method and process. Secondly, all of them use locally produced grains and can be classifiable as belonging to the common category of yakju (clean spirit) with fragrant elements added for the purpose of enhancing health or decreasing any harmful effects after drink. Thirdly, these traditional folk wines are characterized by the addition of secondarily fermented spirits. The more secondarily fermented spirit a wine has, the more fragrant and palatable it becomes and also the less harmful. Fourthly, all the spirits of this region are fermented by using yeast kodupap (steamed rice). The brewing temperature is usually around $15{\sim}20^{\circ}C$ for $5{\sim}8$ days or $3{\sim}4$ days for the majority of the cases. Fifthly, purifying is done with the yongsoo (strainer), the sieve, traditional Korean paper, etc. As such, we can say that all the brewers endeavor to maintain Korean traditional methods of wine making.

  • As people know how to brew a wine from fruits and cereals, they continued to develope various wines good to their taste. Korean wines are also ones made from cereals and they have long been eager to improve the delicate taste. They used to drink Takju, raw rice wine, made from nonglutinous rice and Nuruk, a kind of yeast starter. During Koryo Dynasty, Soju a liquor was imported from Won(the Chinese dynasty). Nowadays this traditional folk wine, which had been developed variously and drunk all over the country, is decreasing year after year. The purpose of this study was to review on the wines ; its kinds, raw materials, brewing method, manufacturing utensils, measuring units and devices and the terms for wine making based on 20 documents published in 1600, in the middle of Yi dynesty. The results of review were as follows. 1. There were 121 kinds of wines at that time in Korea. 2. Among the raw materials for wines, major materials were glutinous rice, nonglutinous rice, wheat flour, wheat, mung bean, and black soybean. And minor materials were pepper corn, Lycium chinenisis, cinnamon, pine needles, pine nuts, jujube, mugwort leaves, lotus leaves, pine corn, pine bud, chrysanthemum, pine flowers, honey, Acanthopanox seoultenses, bamboo-root, marrowbone of blak cow, sweet flag, Ciprus noblis, Saurea lappa, honey suckle, Tricho santhes, azalea, the leaves of the paper mulberry, and bark of chungum tree. 3. There were several kinds of wines such as a wine without using Nuruk, a wine made from glutinous rice, nonglutinous rice, or glutinous and nonglutinous rice with flour. 4. There were several brewing methods for wines such as a wine boiled with ring rice cake, a wine brewed with loaves of rice cake, a wine brewed with hard boiled rice, a wine brewed with rice gruel, and a wine brewed with powdered rice gruel. 5. There were 23 kinds of utensils including measuring devices for weight and volume.

  • This study investigated the quality characteristics and physiological activities of takju prepared with whole chestnut (15%, 30% and 50% with steamed rice) during fermentation. The pH level began to decrease after the secondary brewing stage. The total acid as well as the organic acid content increased during fermentation. Lactic acid and succinic acid were the main organic acids in takju fermented with whole chestnut. The level of total sugar and reducing sugars in takju fermented with whole chestnut increased at the first brewing stage and then slowly decreased after 4 days of fermentation. Also, the total number of viable cells and microbial populations such as lactic acid bacteria and yeast in the treatments increased to about 108 CFU/mL after 1 days of fermentation and then decreased gradually afterward. The ethanol content in takju fermented with whole chestnut rapidly increased during the initial 4 days of fermentation, to a maximum content of 18.2% after 8 days. The colour values of the treatments did not show any significant differences between 0% and 15% chestnut content. However L value decreased, while the a and b values increased when the whole chestnut content above 30%. The total polyphenol level, electron donating ability, nitrite-scavenging ability and ferrous ion effect also increased as the ratio of whole chestnut increased. Sensory scores of takju fermented with 15% chestnut were greater than those of takju prepared by other treatments.
