Recently, several health benefits of rice wine, makgeolli, were known due to the interest on the traditional Korean liquor and the researches on the rice wine are increasing. Organic acids produced during the process of rice wine fermentation play important roles in the taste and flavor. In this study, we have examined the optimal conditions for lactic acid production in rice koji as a carbon source. Skim milk was also used as a supplementary ingredient for the optimization of lactic acid fermentation. Bacterial growth of Lactobacillus sakei was monitored under this condition. The pH, acidity of the culture and the ethanol tolerance of this bacterium were also tested. Through these experiments, we were able to optimize the growth condition of lactic acid bacteria by the addition of skim milk. This was also able to affect the change of pH, acidity, sugar concentration and alcohol tolerance, which might contribute to the improvement of the quality of rice wine. The optimal condition for the growth was 2 days with 10% (w/v) of skim milk concentration. With these results, it was confirmed that rice koji was an effective carbon source for the growth of lactic acid bacteria.

Due to a surplus of rice on the market, there has been a growing interest in developing better processed rice products, especially rice liquor or spirits which are popular and have a large market value. In this study, Takju was made with different varieties of rice and rice powder particle sizes, after which a taste survey was performed and measurements were taken on the characteristics of Takju including the temperature of the fermenting material, sugar content, alcohol content, acidity, amino acid types, colors, etc. The varieties of rice used in the study included Chucheong, Hiami and Anda. The temperature of the brew for each kind of Takju reached its highest point 48 hours after preparation. Differences among rice varieties were only apparent in the acidity and taste evaluations. The acidity was found to be highest with Anda, followed by Chuchoeng and Hiami. Chuchoeng had the highest taste evaluation scores. With regards to particle sizes, the alcohol content and acidity were found to be highest with coarse rice powder while ultra fine rice powder showed the highest fermenting temperature, sugar content, acidity, amino acid type, pH level, color and taste scores right after preparation. The results of this study suggest that among the kinds of Takju made from different rice varieties and particle sizes, the one made from Chucheong ultra fine rice powder is the most preferable over other variations.

This study was performed to investigate the pollution-free Korean traditional papermaking characteristics from paper mulberry by sulfomethylation pulping. Bast fibers were pulped by sulfomethylated cooking liquor, and by alkali and alkali-peroxide processes for the comparison. Sulfomethylated pulping resulted in the superior pulp with high yield and better quality compared to those of alkali and alkali-peroxide pulps. Since the pulp was so bright, there was almost no need additional bleaching. Pollutant loads of sulfomethylated pulping effluent were very low in terms of pH, turbidity and color compared to those of alkali. Pollution-free effluents was accomplished by simple filtering treatment with pine bark, charred rice hull and sawdust compost. Pine bark was the most effective in reduction rate of pollutants.

This study aims at exploring the nature of the traditional Korean wines brewed throughout the Southern Region of Korea-Chulla-do, Kyungsang-do and Cheju-do describing their varieties and brewing methods and also comparing the similarities and differences of their features. When compared with the wines produced in the Central Region, the Southern varieties are very fastidious and complex in their brewing methods, which in turn show a wide range of diversity. First of all, all the 29 kinds of wines investigated, not a single one shows any resemblance to any one of the remaining, each exhibiting peculiar and particular characteristic features of its own. Especially, the distilling methods demonstrate very complex processes. Secondly, the majority of the Southern spirits are made from grains, added with fragrant flavor of pine tree, wormwood, chrysanthemum leaves and other medicine herbs such as Chinese matrimony vine and tankui. Thirdly, they are brewed with yeast made from wheat into kodupap(steamed rice) type of spirits, emerging as in the form of blended liquor. Fourthly, in brewing, different fermenting temperature and duration are required. Typewise, the temperature required for the basic spirit is $15{\sim}20^{\circ}C\;or\;25{\sim}30^{\circ}C$ : in the case of blended secondarily fermented liquor, from the minimum of $0{\sim}5^{\circ}C$ to the maximum of $75{\sim}80^{\circ}C$. The brewing duration is $3{\sim}5$ days for the basic spirits. In some cases, from the minimum of 3 days to the maximum of 100 days are consumed for fermenting. Fifthly, the wine extraction gadgets are yongsu (wine strainer), the sieve, filter paper, Korean traditional paper, the utilization of which implies that the brewers endeavor to observe and preserve the traditional and indigenous methods of wine making.

This study will introduce the foods recorded in Gyemiseo and disclose the substantive characteristics of traditional Korean food in the early stage of the Joseon Dynasty. Gyemiseo is a cook book manuscript written in the Chinese language that was rebound into book format at the end of the Joseon Dynasty in 1911, some 358 years after it was originally written in the $163^{rd}$ year of the Joseon Dynasty (1554) While the majority of cook books begin with recipes for various types of wines and liquor followed by those for fermented sauces, fermented vegetables (such as kimchi), vinegars and storage methods, etc., Gyemiseo begins with recipes for fermented sauces, followed by recipes for various kimchis, how to make vinegars, main meals, side dishes, rice cakes and confectionaries, with recipes for wines and liquor introduced last. Therefore, it can be assumed that the methods of brewing wines and liquors were additionally recorded for bookbinding. There are a total of 128 recipes recorded in Gyemiseo, including 13 for fermented sauces, 14 for kimchi, 11 for the main meal, 26 for side dishes, three storage methods, four for rice cakes and confectionaries, and 44 for wines and liquors. It is believed that contents of Gyemiseo will provide a foundation on which to pursue researches on the process of transition of cooking methods of traditional cuisines of Korea during the Joseon Dynasty.

The objective of this study was to reduce Nuruk flavor in Korean rice-distilled liquor using different ratios of $Sumizyme^{TM}$ and Nuruk. After 9 days of fermentation at $28^{\circ}C$, alcohol contents and pH were 16.0~17.1% and 3.82~4.16, respectively. An increased ratio of $Sumizyme^{TM}$ decreased alcohol content while increased pH of the mash. In alcohol contents, there were no significant differences up to 30% substitution of Nuruk to $Sumizyme^{TM}$. A descriptive analysis was conducted with trained panelists for determining the intensity of Nuruk flavor. The intensities of Nuruk flavor in mashes and distilled liquors brewed by traditional Nuruk, cultured Nuruk, and a mixture of 30% $Sumizyme^{TM}$ and 70% cultured Nuruk were evaluated. The mash and distilled liquor prepared using a mixture of 30% $Sumizyme^{TM}$ and 70% cultured Nuruk showed significantly lower intensities of Nuruk flavor when compared with those of mashes and distilled liquors produced by the traditional and cultured Nuruk.

Black liquor staining for the development of natural color of bleached Hanji caused problems of discoloration and degradation. This study was carried out not only to complement these problems but also to develop natural dyeing method that was similar to the color of unbleached Hanji, through the dyeing of rice straw extractives. The dyeing properties of Hanji were influenced more by dyestuffs extraction method than extraction and dyeing time. Dyeing ability of hot water extractives was superior to cold-water extractives. Without the relation to the time of extraction and dyeing, the color of Hanji dyeing hot water extractives were similar to the control, and the color of Hanji dyed for 45 min with hot water extractives that extracted for 120 min, were almost same as the control. As natural dyestuffs, hot water extractives of rice straw showed that excellent dyeing ability for the development of various natural colors similar to unbleached Hanjis.

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.
