This study is to develop wine with germinated brown rice and red pepper (Capsicum annuum) and to make effective use of the rice and red pepper. The results of alcohol fermentation were as follows. pH 5.5 was decreased to 4.5$\sim$5.1 during fermentation. The total acidity was changed from 0.56% in initial fermentation to 0.96$\sim$1.42% in after fermentation. Reducing sugar was changed from 0.27% in initial fermentation to 1.33$\sim$1.40% at the end of the fermentation. The ethanol content was 16.6$\sim$17.0% at the end of the fermentation. The addition of 10$\sim$50% red pepper did not have influence on the fermentation. From Hunter's L, a, and b values, a (redness) and b (yellowness) value were increased according to content of red pepper addition. The major volatiles were ethyl acetate, 1-propanol, 2-methyl-1-propanol, 3-methyl-butanol and benzeneethanol. Capsaicin content in the samples of red pepper addition was the highest in 50% and the lowest in 10%. In sensory evaluation, the wine with 20% red pepper had the highest acceptance scores in all of the properties examined than those of other samples.

Korean traditional rice wine, Makgeolli, has been widely consumed with increasing popularity in Korea. Also, there has been an increase in the varieties of Makgeolli for the younger generation. In this study, we examined the physicochemical and microbial properties of Makgeolli supplemented with cucumber during fermentation. Four hundred grams of cucumbers (20% of the total amount of rice) were grinded and added to the rice solution (2 kg rice and 3.12 L distilled water) along with the Nuruk (40 g) and yeast (14 g). After mixing the solution, it was fermented for six days in a water bath ($28^{\circ}C$). During the fermentation, the pH value of the cucumber Makgeolli fell from 5.88 to 3.94 on day-1, and steadily increased to a pH value of 4.48 by day-6. The total acidity of the cucumber Makgeolli sharply increased from 0.02 to 0.20% on day-1, and then slowly increased thereafter to 0.28% by day-6. After the 6-day fermentation, the L values of the control and the cucumber Makgeolli were similar. The total viable cell, lactic acid bacteria and yeast count of the control and the cucumber Makgeolli increased considerably after the 6-day fermentation process. Free sugar analysis showed that glucose contents decreased with increasing fermentation periods. The succinic acid content was the highest among all the organic acids. Thirty-nine volatile compounds were observed on the final day of fermentation in the cucumber Makgeolli.

"Woomegi Dduck" is one of Korean traditional pan fried rice cake made from glutinous rice by Tack-joo(rice wine) or boiling water. The optimum conditions for the preparation of "Woomegi Dduck" were investigated. The Hardnes, Cohesiveness, Gumminess, Chewiness, Adhesiveness of "Woomegi Dduck" added Tack-joo or boiling water measured by Rheometer, didn′t have significant difference between samples. The result of color test was L-Value, a-Value, b-Value and E Value of Woomegi Dduck added boiling water and 20％ rice flour were high. The best recipe of Woomegi Dduck was glutinous rice flour 50g, rice flour 20g, Tack-joo 30$m\ell$, or boiling water 25$m\ell$, sugar 10g.

Baekhaju is commonly called Bangmoonju. However comparing Baekhaju while Baekhaju used distiller's grains, Bangmoonju did not use them. Baekhaju used only nonglutinous rice, however, Bangmoonju used glutinous rice or a mixture of glutinous rice and nonglutinous rice. Baekhaju in Chinese, which was misrecored on Baekhaju in Korean from 15th century. However, Baekhaju should be distingnish from Baekhwaju, which is made buy addition of many flowers in various wine. Baekhaju used distiller's grains in the first step of its manufacture procedure. For the fermentation of Baekhaju, one of the three bases, which are rice gruel, rice cake or 구멍떡 was added to distiller's grains. Flours and nuruk are also added. In the second step, steamed water-soaked rice and nuruk was added up to the Baekhaju-base which was got from the first step.

Rice wine cake (RWC) is the solid waste obtained after rice wine fermentation. For the mass production of the spores of yeast Saccharomyces from RWC, the optimum pretreatment condition of RWC, the optimum composition of culture medium, and the optimum culture condition were examined. For sporulation, yeast cells were grown in the pre sporulation medium (PSM), transferred into sporulation medium (SM) containing 1 % potassium acetate, and incubated in a rotary shaking incubator at $25^{\circ}C$ for 4 days. The supernatant of the mixture of RWC and water was used as the presporulation medium (PSM). The optimum temperature and time for the pre-incubation of the mixture of RWC and water (1:2) to obtain maximum sporulation yield were $V^{\circ}C$ and 24 hr, respectively, and optimum culture time in PSM was 48 hr. Using these optimum conditions, the asci number obtained was 0.72$ 1.06${\times}$10^{8}$$m\ell$. The addition of wheat coat koji into SM increased the final number of asci to beTEX>$10^{8}$ $m\ell$. Spores were formed in the SM with the initial pH of 7-11, but no spores were formed in the SM with the initial pH of 5. To save the time and effort to pretreat the RWC, 2% and 0.5% RWC without any pretreatment were directly added into PSM containing 1 % brown sugar and SM, respectively, and the maximum asci number of $1.27${\times}$10^{8}$ /$m\ell$ was obtained.

The goal of this study was to develop a highly valuable Korean traditional ginseng wine containing various bioactive compounds with good acceptability. The effect of some medicinal plants on the quality and physiological functionality of Korean traditional ginseng wine were investigated. Advanced traditional ginseng wine (AG wine) prepared by addition of 0.5% each Pleuropterus multflorus and Pueraria lobata into the rice mash containing 1% ginseng, 0.4% Fermivin(commercial alcohol fermentation yeast) and Koji (2:1 mixture of nuruk and amylase containing 36 Saccharogenic power per g) showed the highest acceptability and ethanol content (16.8%). Changes of functionalities of the AG wine during fermentation at $25^{\circ}C$ for 30 days were investigated. The highest antihypertensive angiotensin I-converting enzyme inhibitory activity (78.9%) and total acceptability of the AG wine were shown after fermentation at $25^{\circ}C$ for 20 days. However, antioxidant activity, SOD-like activity and fibrinolytic activity of the AG wines were not detected or very low. HMG-CoA reductase inhibitory activity of the AG wine was also shown to be 8.2% and 9.2% after fermentation for 15 days and 20 days, respectively.

In order to investigate the effect of different yeasts (La Parisienne (LP), Y18-2, Y54-3, Y90-2, Y90-9 and Y272-7) from nuruks on the quality of Glutinous rice wines, physicochemical properties and volatile flavor components were evaluated. Glutinous rice wines prepared with different yeasts were analyzed for ethanol, pH, total acid, amino acid, soluble solid, coloring degree, UV absorbance, reducing sugar, organic acid, free sugar and volatile compounds. After fermentation for 17 days, the ethanol contents ranged from 13.40 to 14.50%, while the total acid levels were from 0.33 to 0.44%. The amino acid contents in six samples ranged from 0.13 to 0.18%, while soluble solid contents ranged from 12.1 to $14.7^{\circ}Bx$. The glutinous rice wine prepared with LP showed the highest level of coloring degree, soluble solid and reducing sugar among six samples. Organic acid contents of the glutinous rice wine prepared with LP had the highest levels of lactic acid and acetic acid, while the glutinous rice wine prepared with Y90-9 had the highest level of succinic acid. In all glutinous rice wines tested, the most abundant free sugars were glucose followed by maltose. Volatile flavor components in the glutinous rice wines were identified by using GC-MSD. Nineteen esters, ten alcohols, eight acids, one aldehyde and one miscellaneous compound were identified in the glutinous rice wines. Using relative peak area, it was found that other than ethyl alcohol, hexadecanoic acid ethyl ester was the major component, predominantly found in the range of 2.73-10.41%. Phenylethyl alcohol, isoamyl alcohol, ethyl oleate, ethyl linoleate and tetradecanoic acid ethyl ester were some of the major volatile components present through the fermentation, respectively. Overall, it was shown that different yeast strains from nuruks greatly affected chemical and volatile characteristics of the glutinous rice wines.
