  • Six Korean medicinal herbs, Codonopsis lanceolata Traut (sasam), Platycodon grandiflorium A. De Candolle (gilkyung), Paeonia lactiflora var. trichocarpa Bunge (peony), Angelica gigas Nakai (danggwi), Astragalus membranaceus Bunge (hwangki) and Cnidium officinale Makino (chunkung) were added in brewing Korean traditional rice wine. Fermentation characteristics such as contents of total acid, reducing sugar, total sugar, pH, temperature, and alcohol concentration were investigated every 24 hr during fermentation periods. Changes of fermentation characteristics were remarkable in the initial period $(1{\sim}4\;days)$, slow in the middle $(5{\sim}7\;days)$, and almost unchangeable in the final $(8{\sim}10\;days)$. Total acid content was remarkably increased during the initial period but slowly afterwards. Reducing sugar content, total sugar content, and pH were remarkably decreased during the initial period but slowly afterwards. Alcohol concentrations of medicinal herb rice wines were $0.3{\sim}1.5%$ lower than the traditional wine throughout the fermentation periods. After the final period of 10 days of fermentation, alcohol concentration was observed as 12.6% in wine from sasam, 12.9% from gilkyung, 12.3% from peony, 12.4% from danggwi, 13.4% from hwangki, 12.6% in wine from chunkung, 13.6% in raditional wine respectively. Those differences were expected as the results of differences in various herbs. From the sensory evaluation, the highest score of overall quality was observed in the wine from hwangki, the next from chunkung, sasam, the traditewional wine, gilkyung, danggwi and the last from peony.

  • The principal objective of this study was to assess the radical scavenging activities and total polyphenols, flavonoids, and flavonol contents of takju, a Korean traditional rice wine. The antioxidant properties of the wine and takju samples were evaluated using five distinct assays: specifically, 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2-azino-di-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS); hydroxyl; superoxide anion; and nitric oxide (NO) radical-scavenging activity assays. In this study, the takju evidenced strong scavenging activities against the hydroxyl, superoxide anion, and NO radicals. Furthermore, the total polyphenol contents of T-2 were similar to those previously observed in white wine (p<0.05). However, the flavonoids and flavonol contents of all takju samples were significantly (p<0.05) lower than that of white wine. The results of this study show that takju possesses a powerful radical scavenging activity against a variety of oxidative systems. The findings of this study also indicate that takju should be considered a useful antioxidant, and that their functional compound reduces oxidative stress.

  • The changes of pH, titrable acidity, nitrite and dimethylamine(DAM) content in the various different kinds of the rice wine staters during the fermentation were studied, and the changes of nitrosodimethymaine(NDMA) contents were also determined by High Pressure Liquid Chromatography. After 24hrs, fermentation rice wine starter, pH was generally decreased to below 5 and after full fermentation the acidities were from 0.51 to 0.89 as succinic acid. After 12hrs, fermentation nitrate contents were rapidly decreased. The large amount of nitrite was formed in the beginning of the fermentation. But by the increase in the acidity due to the further fermentation nitrite contents were gradually disappeared. Generally the DMA contents of each rice wine starter were kept unchanged. On completion of fermentation, NDMA contents of starter added with nitrite and DMA were 472.1 ppb. The starter added with DMA was 329.0 ppb, whereas the other added with nitrite was 229.0 ppb, and control without addition of nitrite and DMA was 24.4 ppb. But the rice wine sold in market was not detected any NDMA at all.

  • The aim of this study was to develop the new processing method for ginseng. To investigate the efficacy of the new product (the traditional rice wine steamed-red ginseng: RWS-RGS), antioxidant and anticancer effects of RWS-RGS were examined. The DPPH radical scavenging effect of RWS-RGS extracted with ethanol was increased in dose-dependent manner Especially, A3 ($3^{rd}$ traditional rice wine steamed-red ginsengs) exhibited effective DPPH radical scavenging activity. Nitrite scavenging effect of white ginseng (W.G), red ginseng (R.G) and RWS-RGS ($A1\~A9:\;1^{st}$ traditional rice wine steamed-red $ginseng\~9^{th}$ traditional rice wine steamed-red ginseng) were $25.9{\pm}4.4\%,\;12.9{\pm}1.1\%\;and\;26.2{\pm}0.1\~56.1{\pm}0.6\%$ at pH 1.2, respectively. The antitumor effects of W.G, R.G and RWS-RGS (A9) were examined in Hep3B cancer cells. Their growth inhibition against Hep3B cancer cells showed $19.6{\pm}4.5\%,\;54.5{\pm}6.1\%,\;96.3{\pm}2.4\%$ at 5,000 ppm, respectively. These result suggest that the traditional rice wine steamed ginseng will be useful product with antioxidant and antitumor effect.

  • The study was conducted to investigate some grain quality characters related with brewing fittness for rice wine by adopting eight rice varieties as materials. Six japonica rice varieties except two Tongil-type rice had short and round grain of 1.80 or lower grain length/width ratio. 1000-grain weight of brown rice was 21.7~29.5g of significant difference among varieties. The white-center of rice grain was most severe in Hidahomare and Iri 402. Among tested varieties, Seomjinbyeo, Iri 402, Dongjinbyeo and Hidahomare had 50% or higher head rice ratio, while the others had relatively worse milling properties resulted from higher ratio of notched-belly and broken grain. Chemical components and total acid and amino acid content of refined rice wine was relatively good in every variety. Liquifying and saccharificating power was higher and koji conditon was also good in the varieties of high head rice ratio. Seomjinbyeo, Dongjinbyeo and Iri 402 was preferred in sensory test of refined wine and was recognized as superior adaptable rice varieties for brewing rice wine.

  • Eumsikjeoljo (integrity with food) originally came from the Andong district, where the Goseong Yi clan inherited a cookbook from their ancestor Lee Jeong-Rong (1798~1871). The cookbook was written in an antiquated style and is estimated to have been written around the year 1865. Details of the era and authorship are seldom available for the extant ancient cookbooks. The authors of these books and the period during which these books were precisely written were studied through the Eumsikjeoljo which is a repository of 46 cooking disciplines. Of these 10 deal with the practice of traditional Korean crispy snack making, 4 with rice cake making, 3 of the yeonbyeong kind, 19 examples of Korean side dish making, 6 recipes of the kimchi variety, 2 examples of paste-based recipes, and 2 instances of instructions on how to make vinegar-based extracts. Also, in Eumsikjeoljo, there are descriptions of 29 different ways to brew rice wine. Of these, Danyang wine among the Leehwa wines and 13 others account for over 44% of the content. Leeyang wine and Sogok wine are represented by 10 different varieties and constitute around 34% of the entries. Samyang wine and Baek-il wine, along with 6 others, constitute 21% of the entries. The secret recipes of the Goseong Yi clan in the Andong district were recorded so that they could be transferred to the descendants of the clan. An inspection of the recipes and wine brewing techniques recorded in Eumsikjeoljo provides a clearer picture of the mid-1800s Andong noble family's traditional food habits and simultaneously sheds light on the late Joseon dynasty's food culture.

  • This study was carried out to investigate the changes in the storage characteristics of the Korean traditional raw rice wine (RRW) treated with Korean sun-dried salts and gamma rays. Nowadays, RRWs have received attention because they are a nutritious food with health-stimulating properties. But the rapid deterioration of the fermented RRW is one of the serious problems for brewing and marketing in the world. Actually, the expiry date of the RRW is around a week and this has been a biggest disadvantage of the RRW. The goal of this study was to make it of high quality and extend the period of circulation of the RRW. A lactic acid bacterium was isolated from the RRW. The 16S rRNA sequences of isolates showed 98% homology with the Lactobacillus fermentum. These results suggested that could be manageable improve the shelf life with addition of the sun-dried salts and irradiation with gamma rays.

  • Objectives: This study was carried out to investigate the protective effect of Coptidis Rhizoma steamed with rice wine (CR) against gastroduodenal mucosal injury through inhibiting inducible nitric oxide synthase (iNOS) activation. Methods: In in vitro experiment, LPS-induced RAW 264.7 macrophages were treated with CR(0.4, 0.6, 0.8, 1.0 mg/ml) and iNOS mRNA expression and nitric oxide (NO) production were measured. In in vivo experiment normal group mice were treated with neither ethanol nor CR. Both control and sample group mice were orally administrated with ethanol. Five hours after ethanol administration control group mice were orally administrated with distilled water, sample group mice were orally administrated with CR. After three days administration, gastroduodenal mucosa of mice was observed histopathologically and iNOS, nuclear factor-kappa B (NF-${\kappa}B$) activation were observed immunohistochemically. Results: In in vitro experiment iNOS mRNA expression and NO production in LPS-induced RAW 264.7 macrophages were decreased by CR dose-dependently. In in vivo experiment, gastroduodenal mucosal injury was repaired by CR and iNOS, NF-${\kappa}B$ activation in gastroduodenal mucosa were decreased by CR. Conclusions: Coptidis Rhizoma steamed with rice wine has a protective effect against gastroduodenal mucosal injury through inhibiting iNOS activation.

  • To investigate the mycoflora of indoor air in a Sogokju, traditional rice wine, factory, fungi were sampled and analyzed from the air of several rooms in the factory using an Anderson air sampler and from two kinds of Nuruk. Twelve fungal species belonging to the genera of Aspergillus, Penicillium, Gibberella, Cladosporium, and Talaromyces were isolated. Species belonging to Aspergillus and Penicillium genera were the major species. Seven different species of Penicillium were isolated from each different room of the factory. The Aspergillus species found from indoor air of the factory was also found from Nuruk. Rhizopus sp. was commonly isolated from Nuruk but not from indoor air of the factory. This is first report of fungi present in indoor air of a traditional rice wine factory in Korea.
