The present study was performed to obtain data that could be used to popularize yakju(Korean traditional rice wine) by surveying how well rice wine goes with pairing foods. The survey was given to 302 men and women living in the Seoul and Gyunggi areas and work in the food service industry. The Jeon group, Gui group, Jeongol and Jjigae group, Pyeonyuk and Bossam group, and Muchim group were selected as menu items that go well with available rice wines. The survey aimed to identify foods that go well with four rice wines with different sensory characteristics. The survey results showed that both men and women replied that rice wines with Nuruk aroma and Nuruk taste go well with the Jeon group, rice wines with sour and flower aromas and common characteristics go well with the Muchim group, and rice wines with sweet and fruit tastes go well with the Muchim group. However, men and women had different opinions on rice wines having ginseng, soil, and herbal medicine aromas. Men replied that such rice wines go well with grilled meat, whereas women replied that these rice wines go well with Pyeonyuk and Bossan groups.

In this study, the Korean cookbook, Jusiksiui, which was published in the late 1800s, was investigated. The results revealed that Jusiksiui contained more than 100 foods. Specifically, 12 staple foods were foods recorded including five types of porridge, three types of noodles, and four kinds of dumplings. Moreover, 49 side dishes were present, among which Jjim (steamed food) was most common, being recorded ten times. Additionally, seven types of Jeon (pancake) & Gui (roasted food) and Kimchi & Jangajji (pickled vegetables), four kinds of soup and Jeongol (stew), stir-fry, Sukyuk (boiled beef), and three types of Sukchae and Sashimi were found. Moreover, 14 recipes for rice cakes, two recipes for Korean cookies and three recipes for drinks were found. Seven recipes for wine, including plain rice wine, medicated wine and flavored wine, were also found. Finally, four different soy sauces Jibjang (a kind of soy sauce paste), hot pepper paste, Cheonggukjang (fast-fermented been paste), and Jeupjihi and roasting hot pepper paste were observed.

Many food protein hydrolysates have been shown to have antioxidant activities, and recent research focuses on low molecular peptides produced during hydrolysis of food protein. Korean rice wine contains about 60-70% of protein at dry base and originates from raw materials. It has been suggested that the protein is transformed into low molecular weight peptides, and have antioxidant activity during fermentation. The objectives of this study were to evaluate the antioxidant activity of the pre-purified and purified peptides found in Korean rice wine and to identify the responsible peptides. The wine extract of Samhaeju, a traditional Korean rice wine made by low temperature fermentation, was evaporated at $35^{\circ}C$. The two methods employed in the evaluation of antioxidant activity were the DPPH radical scavenging method and the beta-carotene bleaching test. The pre-purified samples showed 808 AAC (Antioxidant Activity Coefficient) and 56.5% AOA (Antioxidant Activity), which were higher than $\alpha$-tocopherol (572 AAC and 78% AOA). The rice wine extract was separated by reversed-phase HPLC. The protective effect of the four most antioxidant active fractions were tested for t-butyl hydroperoxide induced oxidation of healthy human erythrocytes and the byproduct was determined by malondialdehyde formation. Fraction No.5 showed 35% lower MDA concentration as compared to the control. The peptides were further purified using consecutive chromatographic methods and 4 antioxidant peptides were isolated. The amino acid sequences of the peptides were identified as Ile-His-His, Val- Val-His(Asn), Leu-Val-Pro, and Leu(Val)-Lys-Arg-Pro. The AAC value of the synthetic form of the identified peptides was the highest for Ile-His-His.

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.

In order to study the quality of uncooked-colored wine by using polished black rice(PBR) and glucoamylase, the mixture ration of PBR ws investigated. The growths of yeast and lactic acid bacteria, pH and alcohol concentration of the colored wine prepared by adding PBR in the range of 20 to 100% were higher than those of polished rice only, whereas the contents of residual sugars, total free amino acids and fusel oil of the colored wine were lower. The colored wine prepared by 20% PBR and that of over 80% PBR showed a light red color and a dark red, respectively. The optimal addition ratios of PBR evaluated by palatability of color and flavor, and sensory overall quality was 40 to 60%.

Different strains of mold were screened for the production of high quality Korean traditional rice wine with anti-hypertension and good acceptability. We isolated 867 nuruk mold strains and selected 24 for further study based on measurement of amylase activity. Among them, mold No. 17 showed high ethanol production upon fermentation with Saccharomyces cerevisiae as well as anti-hypertensive properties. The No. 17 strain was therefore selected as the functional mold and later identified as Rhizopus stolonifer based on molecular biological characteristics. Optimal fermentation conditions for the brewing of anti-hypertensive traditional rice wine comprised the addition of R. stolonifer No. 17 koji at a concentration of 35 sp/g and a fermentation period of 10 days at $25^{\circ}C$ using S. cerevisiae.

Fermentation characteristics of rice-grape wine with different mixing ratios of rice and grape, rice one vs. grape five (Exp.1), rice two vs. grape five (Exp.2), rice five vs. grape five (Exp.3), and rice five and grape two (Exp.4), were investigated. Final alcohol contents of Exp.4, Exp.3, Exp.2, and Exp.1 were 18.4, 16.0, 14.9, and 12.9%, respectively. Final alcohol content increased with increasing amount of rice. Acidity of four experiments ranged pH 3.4-3.92, and total acidity was 0.52-0.74%. Exp.4, Exp.3, Exp.2, and Exp.1 gave a values of 8.76, 12.77, 12.88, and 23.96, respectively. When different mixing methods were applied to Exp.1, the resulting final alcohol contents of Exp.6 (grape musts periodically added after rice fermentation), Exp.7 (rice and grape simultaneously added and fermented), and Exp.8 (rice added after grape must fermentation) were 2.3-3.2% Bower than that of Exp.1 (grape must added after rice fermentation), and total acidity was 0.72-0.74%. Sensory evaluation comparing conventional red wine and rice-grape wine of Exp.1 showed rice-grape wine was preferred in taste.
