  • To extend the self-life of Dooboo (tofu), fish paste and Makkoli (Korean traditional rice wine) for which severe heat treatment are not expectable, main putrefactive microorganisms were isolated from each product and tested their growth inhibition by ethanol and water extracts of several edible plants. The ethanol extract of Phellodandron amurense Ruprs had the strong effect of growth inhibiting to all three isolates from Dooboo and Makkoli, and Eugenia caryophyllus, Pinus rigia Mill, Bletilla striata (Thunb) Reichb. Fill and Paeonia albiflora Pall were also same effect to isolates from fish paste. The ethanol extract was more effective inhibiting than water extract in all test microorganisms. The evident inhibition level of each extract was 2000 ppm of Pa ethanol for fish paste and 1000 ppm for Makkoli.

  • Various alcohol yeast strains have been isolated from main mashes of Korean traditional liquors, and their genetic diversities were previously reported [23]. In this study, the strain SHY111, showing the highest alcohol production, was tested for its fermentation and sporulation characteristics. Additionally, its haploid cells were isolated and tested for their growth and fermentation patterns. The strain was identified as Saccharomyces cerevisiae based on its morphological and physiological characteristics. The sequences of the ITS(internal transcribed spacer) and 5.8S rDNA regions of S. cerevisiae SHY111 were found to be identical to those of S. cerevisiae that was obtained from through the yeast genome project. The maximum fermentation ratio obtained by the strain SHY111 (96.7%) was almost the same as that by S. cerevisiae Balyun No. 1 (96.5%) that was a little higher than that by S. cerevisiae KCCM11215(95.8%). The strain was induced for sporulation in a sporulation liquid medium using log phase cells grown in different types of pre-sporulation media, and its haploid cells were obtained by spore dissection using a micromanipulator. The majority of the spores formed a small colony on a YPD agar plate, and the haploid yeast cells derived from the strain SHY111 showed a variety of growth and alcohol fermentation patterns. It was proposed that the fermentation patterns were related to their growth phenotypes in the most haploid strains, but possible not in some strains.

  • Ethyl carbamate (EC) classified as a probable human carcinogen (Group 2A) is naturally formed in alcoholic beverages and fermented foods during fermentation process and/or during storage. The objective of this study was to analyze EC in 34 food items including 14 alcoholic beverages and 20 fermented foods sold in Korea. Each food was collected from 18 supermarkets in 9 metropolitan cities in Korea, and then made into composite. According to food composition and alcohol content, samples were divided into four matrices such as apple juice, milk, Soju (liquor containing about 20% alcohol), and rice porridge. The maximum EC value of $151.06{\mu}g/kg$ was found in Maesilju (liquor made from Maesil and Soju). Whisky and Bokbunjaju (Korean black raspberry wine) contained $9.90{\mu}g/kg$ and $6.30{\mu}g/kg$, respectively. EC was not detected in other alcoholic beverages. Of 20 fermented foods, Japanese-style soy sauce had highest level of $15.59{\mu}g/kg$ and traditional one contained $4.18{\mu}g/kg$. Soybean paste had $1.18{\mu}g/kg$, however, EC was not found in other fermented foods.

  • These fermented food has been increased interest to people's health in recent years. Factors which have taste, storability and trophism of fermented food is affected food of material, temperature, humidity and pH. But fermented food has yet not been established of model equation for the change in pH. If they that seller and consumer can know the status and quality, customer could increase credibility and consumption-oriented about fermented foods. In this paper, we obtain model equation through measured PH of fermented foods. So, model equation is offered platform about maturity of fermented foods. In order to confirm the usefulness of the proposed model equation, we tested the change in PH about a kimchi and a rice wine which is fermented food of Korea representative.

  • LAB were isolated from makgeolli locally produced around Jinju, Gyeongnam, S. Korea during spring of 2011. Randomly selected 11 isolates from MRS agar plates were identified first by API CHL 50 kits and then 16S rRNA gene sequencing. All 11 isolates were identified as Lactobacillus plantarum. Among them, ST4 grew in MRS broth with ethanol up to 10%, showing the highest alcohol resistance. L. plantarum ST4 was moderately resistant against acid and bile salts. When cellular proteins of L. plantarum ST4 under ethanol stress were analyzed by two-dimensional gel electrophoresis (2DE), the intensities of 6 spots increased, whereas 22 spots decreased at least 2-fold. Those 28 spots were identified by peptide mass fingerprinting (PMF). FusA2 (elongation factor G) increased 18.8-fold (6% ethanol) compared with control. Other proteins were AtpD (ATP synthase subunit beta), DnaK, GroEL, Tuf (elongation factor Tu), and Npr2 (NADH peroxidase), respectively. Among the 22 proteins decreased in intensities, lactate dehydrogenases (LdhD and LdhL1) were included.

  • Korean medicinal herbs -sasam, gilkyung, jakyak, danggwi, hwangki and chunkung were soaked to the distillate of Korean rice wine for 75 days. The alcohol concentration of distillate, soaking media was adjusted to 45, 35, and 25% respectively with distilled water. Changes in alcohol concentration, pH, optical density, concentration of peoniflorin and decursin were analyzed. Quality of the final product was determined by sensory evaluation. Alcohol concentration was rapidly decreased but pH increased in 15 days and thereafter they showed slow decrease. Decrease of alcohol concentration was affected by the kind of herb and alcohol concentration of soaking media. The strongest effect was observed from danggwi and low alcohol concentration. Concentration of paeoniflorin and decursin, an index component of jakyak and danggwi respectively, showed the similar trend of decrease after increase to maximum concentration. From the sensory evaluation, the best overall quality was obtained from liquors made from 45% alcohol concentration. The quality was decreased in the order of sasam, jakyak, chunkung and hwanggi.

  • The distribution of lactic acid bacteria and total bacteria in 27 samples of Nuruk (traditional Korean rice wine starter) were investigated, and lactic acid bacteria isolated from those samples were identified. The average number of lactic acid bacteria and total bacteria were $2,11{\times}10^7$ and $2.08{\times}10^8\;cfu/g$, respectively. There was no appreciable differences in the number of lactic acid bacteria among those samples, meanwhile the number of total bacteria varied significantly from sample to sample. Among the lactic acid bacteria, more cocci were counted than rods in those samples. Thirty-two strains of lactic acid bacteria obtained from those samples were identified as Leuconostoc mesenteroides subsp. mesenteroides (11 strains), Pediococcus acidilactici (7 strains), Lactobacillus plantarum (3 strains), L. murinus (7 strains) and Enterococcus faecium (4 strains).

  • Li was a sweet beverage containing $2{\sim}3$ percents ethyl alcohol made from malt by spontaneous fermentation from ancient custom to fifteenth century. Li was changed to the rice wine being a sweet beverage of low alcohol content using nuruk as starter and the sikhae which is non-alcoholic fermented beverage. Li was made for drinking and ceremony in Korea, China and Japan. It disappeared from the beverage items along with its method of manufacture from malt, but in Korean had made Li using nuruk until recent. We made Li according to Book of Imwon-Keongjae Ji (The book of country economy) methods for reappearance of Li. Fermentation characteristics for the production of Li with Saccharomyces cerevisiae, Saccharomyces bayanus and Saccharomyces sake were investigated. Among the yeast strains tested, Li fermented with S. sake showed higher alcohol production. Total sugar decreased considerably during the whole period of fermentation(30 hours), while ethyl alcohol content increased at $2.98{\sim}3.52%$. As the fermentation progressed, the pH decreased until the 30 hours of fermentation, while total acid increased during the same period. In fermentation of 36 hours, Li consisted of about $2.98{\sim}3.52%$ of alcohol content, $5.3{\sim}6.0%$ of total sugar, $1.45{\sim}2.21mg%$ of reducing sugar and total acidity were reached up to $24.4{\sim}29.5mg%$ for Li manufactured with S. cerevisiea sake, S. bayanus and S. sake.

  • The purpose of this study was to determine the optimum condition for producing tea leaf Jeung-pyun that does not contain added parched tea leafs (0, 0.5, 1, 1.5, and 2%) while producing Jeung-pyun that has a variety of functional ingredients and to investigate the possibility of making practical application of tea leafs. Moisture contents were 56 ~66% and there were no significant differences among the samples. The pH of Jeung-pyun samples was 5.65~5.74. The L-value decreased as the amount of added tea leaf increased, and the a-value was low in the group made with added tea leafs. The b-value was high in the 1% added group and had a tendency to increase vs the control group as amount of added tea leaf increased. In the groups with added tea leaf the volume was evaluated as being higher in the order of 1>1.5>2%. The specific volume of the group with added tea leaf was evaluated as being higher in the order of 1>1.5>2%. Sensory characteristics of the group with added tea leaf were evaluated as being high. For characteristics of cell uniformity, rice wine flavor, and sweetness, the control group was evaluated as being high, and for characteristics of color, moistness, and softness the 1% added group was evaluated as high. Astringency was evaluated as being high in the 2% added group. Texture profile analysis was conducted after samples were maintained in an incubator at $20^{\circ}C$ for 0, 1, 3, 5, and 7 days. Characteristics for hardness, gumminess, chewiness tended to increase with longer periods of storage. Characteristics for cohesiveness, springiness tended to decrease as the storage period increased. As determined by this study, addition of 1% tea leaf was the most favorable method for making use of tea leafs the production of Jeung-pyun and a potentiality for the use of tea leafs in food was discorvered.

  • In the early years of the Koryo dynasty(877~1392), the grain production was encouraged and the consumption of meat was abstained because of the Buddhism. Therefore, desserts including rice cos and cookies and teas were prevalent. Specially, the cooking skill of the desserts was highly developed because the desserts were the requisite of offered in Buddhist service and national ceremonies. Also, the king took the lead in abstaining to eat meat. According to $\boxDr$Koryodokyung$\boxUl$ , People in the early Years of the Koryo dynasty were unskilled to slaughter for serving meat to the envoy from China. Most ceremonies in Koryo dynasty were held fur retainers by king and the ceremonies held to celebrate the coronation, birth of the royal grandchildren, and royal birthday, and to treat the envoys and merchants from China(Song dynasty) and Tamra kingdom. The ceremonies were continuously held from the early year to the later year of Koryo dynasty. The aristocracy of the Koryo dynasty often held the extravagant ceremonies and drank liquor a lot in the ceremony and offered the extravagant foods such as oil-and-honey pastry and milk, which caused the national problem later. The royal religious ceremonies held often in the Koryo dynasty were ancestor worship ceremony, tea ceremony, lotus lantern ceremony, Palgwanhoe, etc. In Koryo dynasty, there were several government offices that took charge of royal dietary culture as follows: 1. Yomulgo (料物庫) - government office supplied with provisions 2. Sasunseo(司謄署) - government office that took charge of various kinds of side dishes 3. Saonseo(司酪署) - government office that took charge of wine and liquor 4. Naejangtaek(內莊宅) - government office managed paddy fields and dry fields owned by royal family 5. Sangsikguk(尙食局) - government office same as Sasunseo that took charge of various kinds of side dishes, the name changed to Sasunseo later 6. Sungwanseo (謄官署) - government office that took charge of foods for various religious services and ceremonies 7. Naewonseo (內園署) - government office that took charge of the garden
