  • To develop a new traditional Gugija tagju, various koji were prepared using several starch sources along with Aspergillus awamori var. kawachi, and then their effects on the quality of the tagju were investigated. Ethanol contents(11.1${\sim}$13.8%) were not significantly different among the Gugija tagju made from the various types of koji, whereas the tagju made using non-glutinous rice koji had the best total acceptability. The addition of 1% Gugija extracts into the mash increased its total acceptability and anti-hypertensive angiotensin I-converting inhibitory activity, and the optimal fermentation period for brewing the Gugija tagju was 10 days.

  • Tarak is a traditional Korean fermented milk product, which is prepared by the addition of rice wine to milk. The major microbial strains found in Tarak are Leuconostoc citreum, Lactobacillus plantarum, Lactococcus lactis, Saccharomyces cerevisiae, and Pichia kudriavzevii. The activity of lactic acid bacteria isolated from traditional Korean foods of Taraki against the carcinogenic bacteria Helicobacter pylori, Escherichia coli O157:H7, and Cronobacter sakazakii was characterized. Tarak extract significantly increased the proliferation of T-lymphocyte Jurkat (clone E6-1) cells. Tarak also inhibited the tyrosinase activity and melanin biosynthesis induced by an ${\alpha}$-melanocyte-stimulating hormone in pituitary intermediate lobe.

  • Jeung-Pyun Is a traditional fermented Korean food made with rice flour, water, sugar salt and unrefined rice wine(Tak-ju). In order to investigate how the addition of soybean and dextran have an influence on Jeung-Pyun fermentation and forming structure of Jeun-Pyun, adding soybean 20% and dextran 1%based on rice weight, we measured physicochemical properties. Also we measured dextran content of Jeung-Pyun batter according to the fermentation time and observed the inside of Jeung-Pyun by SEM in order to find out air pore condition. The dextran content of rice Jeung-Pyun and Jeung-Pyun adding soybean 20% was gradually increased as fermentation time was longer and Jeung-Pyun adding soybean 20% was higher than rice Jeung-Pyun. The specific volume of rice Jeung-Pyun and Jeung-Pyun adding soybean 20% was increased up to a fermentation time of 7~ 10 hours but it was decreased as fermentation time was longer. In the inside structure of Jeung-Pyun observed by SEM, the fermentation condition of Jeung-Pyun fermented for 3 and 7 hour was better and air pore size became larger, the number of it was decreased as fermentation time was longer. The air pore size of soybean 20% Jeung-Pyun is smaller more uniform than that of rice Jeung-Pyun. In conclusion. it can be suggested that the audition of soybean improves the quality of Jeung-Pyun and dextran has an influence on fermentation and forming structure of Jeung-Pyun.

  • Tarak is a Korean traditional fermented milk product that is fermented by adding rice wine to milk. Tarak was produced with Lactobacillus paracasei ssp. paracasei M13-65-3 isolated from rice wine, and its effects on immune cell proliferation and melanin biosynthesis were investigated. Tarak extract significantly increased proliferation of T lymphocyte Jurkat clone E6-1 cells at concentrations from 10 to $100{\mu}g/mL$. Tarak inhibited activities of tyrosinase and ${\alpha}$-melanocyte-stimulating hormone-induced melanin biosynthesis in mouse skin B16-F10 cells at a concentration of $100{\mu}g/mL$. These results suggest that tarak might have functionalities for enhancing the immune system by increasing immune cell proliferation and regulating melanin biosynthesis.

  • The quality and antioxidant activity properties of Jinyangju, Korean traditional rice wine made with different additions of Citrus junos peel (0, 10, 20, 30, and 40%) were investigated. The pH and the total sugar content of the Jinyangju decreased, whereas the total acidity and alcohol content increased with greater additions of Citrus junos peel. The color L-value increased and the color a- and b-values decreased with increasing amounts of Citrus junos peel. The DPPH (1,1-diphenyl-2-picryl-hydrazyl) free radical scavenging activity increased with the addition of Citrus junos peel. The highest overall acceptability values in the sensory test for color, flavor, taste, and overall favorite were 4.2, 4.9, 5.6, 5.0, and 3.9, respectively, with the addition of 20% Citrus junos peel.

  • Five takju prepared using four types of nuruk (a traditional Korean fermentation starter made of malted wheat; non-cooked, naturally inoculated) labeled SH, SS, JJ, and SJ, and one type of koji (cooked, inoculated with an inoculum) labeled MN, were compared. Titratable acidity, pH, sugars, ethanol, amino acids, organic acids, and microbial changes in samples were measured, and the sensory properties were evaluated. Titratable acidity, alcohol, and organic acid content increased as sugar contents decreased. The overall ethanol concentration of all takju increased over time, reaching a maximum of 13.08-14.96% (w/v) at 7-21 days. The total amino acid contents of takju prepared with nuruk, except for one (SJ), were higher than the takju prepared with koji (MN). Lactic acid bacteria were also isolated from the starters. Sequence analysis of 16S rRNA genes (500 - 600 bp) of 223 isolates revealed that the major strains were in the genera of Leuconostoc, Weissella, Pediococcus, and Lactobacillus.

  • The objective of the present study is to elucidate the physicochemical and microbial properties of Korean traditional rice wine, Makgeolli, supplemented with mulberry during the fermentation process. Four hundred grams of mulberries (20% of the total amount of rice) were ground and incorporated into the rice solution (3.5 L of distilled water, 2.0 kg of rice, 28.0 g of yeast, and 80.0 g of nuruk). The rice solution was then placed in a water bath set at $28^{\circ}C$ and left to ferment for 7 days. The alcohol contents between the control and mulberry Makgeolli were not significantly different. The pH values of the control and mulberry Makgeolli decreased and the total acidity values were elevated after a 7-day fermentation. In the microbial analysis, the total viable cell count, lactic acid bacteria count and yeast count increased considerably through the 7-day fermentation process. For all the samples, the glucose and succinic acid contents were highest among all free sugars and organic acids, respectively. Forty-eight different volatile compounds were found in all the samples after the 7-day fermentation process.

  • Jeung-pyun, a fermented rice cake, is prepared by fermenting rice sourdough using makgeolli, a traditional Korean rice wine, in the presence of yeast and lactic acid bacteria (LAB). The goal of this study was to conduct biochemical and microbial analyses of five different rice sourdoughs, each fermented with a different commercial makgeolli, using culture-dependent and culture-independent approaches. All sourdough samples fermented with different makgeolli for 6.5 h showed different profiles in pH, total titratable acidity, organic acid concentration, and microbial growth. LAB belonging to different genera were identified based on colony morphology on modified MRS and sourdough bacteria agar medium. PCR-denaturing gradient gel electrophoresis analyses of the five sourdoughs showed different bands corresponding to LAB and yeast. 16S/26S rRNA gene sequence analyses of the samples confirmed that the predominant LAB in the five fermented rice doughs was Lactobacillus plantarum, Lb. pentosus, and Lb. brevis. Various other Lactobacillus spp. and Saccharomyces cerevisiae were common in all five fermented samples. This study provides comprehensive and comparative information on the microflora involved in fermentation of rice sourdough and signifies the need to develop effective starters to enrich the quality of jeung-pyun.

  • To improve of the quality of Korea traditional wheat-rice wine (makgeolli) production, we used a rice fermentation starter (rice nuruk) made by inoculation of Rhizopus oryzae CCS01 which was isolated and selected from commercial nuruk. Amylase activity of a rice nuruk was 1.8-2.4 times higher than those of commercial nuruks. The best acceptability of wheat-rice wine in a sensory test was observed at 4 : 6 ratio of wheat-rice mash at experimental condition. During the fermentation period, pH of wheat-rice makgeolli made with a rice nuruk was higher compared to those made with commercial nuruks such as Sanseong, Jinju, and Songhak. Acidity of makgeolli mash was lower in case of using a rice nuruk and birx and alcohol production were higher compared to those of makgeolli mash using commercial nuruks. Highest alcohol production was observed at makgeolli mash using a rice nuruk and 12% of alcohol was produced at fermentation end. These results suggest that production of a new type of wheat-rice makgeolli using a rice nuruk was possible.

  • This study was conducted to develop a high value pear Makgeoly that possessed the physiological functionality of pears and rice. To accomplish this, the effects of the addition of pears on the alcohol fermentation of Korean traditional rice wine, Makgeoly were investigated. The total acidity contents were unchanged for 9 days of fermentation after the addition of pear to the mash, however, it decreased by approximately 0.13% after 9 days. Additionally, the ethanol contents increased to 16.0% after 5 days of fermentation, after which they did not change significantly. The residual reducing sugar and free sugar content were decreased after 7 days and 5 days of fermentation, respectively. The total acceptability was the best in the Makgeoly that contained grated pear after 10 days of fermentation. Additionally, antihypertensive angiotensin Iconverting enzyme inhibitory activity was found to be greater than 80% in all pear Makgeoly, but the fibrinolytic activity, SOD-like activity and antioxidant activity were weakened. Based on these results, Makgeoly that was brewed by the addition of 20% grated pear into the fermented broth from fermentation at $20^{\circ}$ for 10 days has the potential to become a new functional Korean traditional Makgeoly with high acceptability and antihypertensive properties.
