Objectives : The objectives of this study was to obtain acute information (single oral dose toxicity) of Red-Koji (Monascus purpureus 12002) Fermented Scutellariae Radix Aqueous Extracts (fSR), has been traditionally used in Korean medicine for treating various diseases including inflammatory diseases. Methods : In order to observe the 50% lethal dose (LD50), approximate lethal dosage (ALD) and target organs, fSR powders were once orally administered to female and male ICR mice at dose levels of 2,000, 1,000, 500 and 0 (control) mg/kg (body weight.). The mortality and changes on body weight, clinical signs and gross observation were monitored during 14days after single oral treatment of fSR with organ weights and histopathological observations of 12 types of principle organs. Results : After single oral treatment of fSR, we could not find any mortality and toxicological evidences up to 2,000 mg/kg treated group, the limited dosages in rodents, on the body and organ weights, clinical signs, gross and histopathological observations, except for some accidental findings. Conclusions : The results obtained in this study suggest that the LD50 and ALD of fSR in both female and male mice after single oral treatment were considered as over 2,000 mg/kg because no mortalities were detected up to 2,000 mg/kg and can be safety used in clinics.

Changes in rutin and Quercetin contents of Gochujang, which was added buckwheat flour, were investigated during steaming and fermentation for 1 month. Not steamed buckwheat flour showed only in presence of rutin. But rutin decreased and quercetin increased after steaming. The koji of buckwheat flour showed maximum contents of rutin and Quercetin at 20 hours during fermentation. The rutin content of Gochujang made with koji of buckwheat flour decreased slightly during fermentation but the Quercetin content increased with decreasing contents of rutin, probably due to degradation of rutin. All rutin degraded completely in Gochujang made with koji of buckwheat flour after 20 days.

To develop a high-valuable Korean traditional rice wine having antihypertension, effects of some cereal kojis and legumes on alcohol fermentation and angiotensin I-converting enzyme (ACE) inhibitory activity of Korean traditional rice wine were investigated. Korean traditional rice wine brewed by addition of 10% Indian-millet koji into the mash showed the greatest ACE inhibitory activity of 43.0% and good ethanol productivity. The ACE inhibitory activity increased up to 69.2% by addition of 50% of mungbean powder and 1% of dandelion petal into the mash.

The purpose of this study was to compare the quality characteristics of each brown rice glutinous rice red pepper paste prepared. In this study, brown rice, glutinous rice, and red pepper paste were prepared with various enzyme preparations. A 20-day study of the physicochemical and microbiological properties of each enzyme through the results process showed significant differences. In particular, brown rice red pepper paste manufactured using cozies purchased from Sunchang was functionally superior to rice cozies and bean cozies, with probiotics of 7.1-7.5×107 CFU/mL, lactobacillus of 1.9-2.2×103 CFU/mL, 48.67-52.30%, and 58.57-63.90%. When the results were combined, the composition of microorganisms and enzymes of fermented soybean paste purchased from Sunchang was not confirmed, but brown rice chili paste with nutritional and functional properties could be prepared compared to A.oryzae and A. kawachii.

Objective : This study aimed to assess the preventive effect of Bupleuri Radix aqueous extracts (BR) and red koji-fermented BR (fBR) in lipopolysaccharide (LPS)-induced acute lung injury in a rat model. Methods : Rats were administered 30, 60, or 120 mg/kg/day of fBR for 28 days before LPS treatments. All rats were sacrificed 5 h after LPS treatment (500 ㎍/head, intratracheal instillation). Body weights, lung weights, pulmonary transcapillary albumin transit, arterial gas parameters (pH, partial pressure [Pa] of O2, PaCO2), bronchoalveolar lavage fluid (BALF) protein, lactate dehydrogenase (LDH), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), total cell numbers, neutrophil/alveolar macrophage ratios, lung malondialdehyde (MDA), and myeloperoxidase (MPO) were measured. In addition, histopathological changes including the luminal surface of alveoli (LSA), thickness of alveolar septum, and number of polymorphonuclear neutrophils (PMNs) were checked. Results : LPS injection led to increases in lung weights, pulmonary transcapillary albumin transit, BALF protein, LDH, TNF-α and IL-1β contents, total cells, neutrophil and alveolar macrophage ratios, lung MDA, MPO, alveolar septum thickness, and PMNs, and decreases in PaCO2 and pH of arterial blood and LSA. However, these LPS-induced acute lung injuries were inhibited by pretreatment of 30, 60, and 120 mg/kg of fBR. The most favorable effects were seen with 30 mg/kg fBR as compared with 60 mg/kg of α-lipoic acid and BR. Conclusions : fBR showed preventive effects on LPS-induced acute lung injury, which resembles acute respiratory distress syndrome. The mechanisms of action were likely via antioxidant and anti-inflammatory means.

Alcoholic fermentations with rice koji [Aspergillus awamori Nakazawa KCCM 60246 (black), Aspergillus kawachii KCCM 32819 (white), Aspergillus oryzae KCCM 11372 (yellow)] and improved nuruk were carried out for the preparation of sweet potato soju using two different potato cultivars (Jinhongmi and Hobak). The Jinhongmi mashes showed $9.2-11.4^{\circ}Brix$, 195.6-260.5 mg glucose/100 mL, pH 4.6-4.9, 0.53-0.83% acidity and 13.2-16.2% alcohol content. The Hobak mashes showed $7.0-8.4^{\circ}Brix$, 31.9-47.4 mg glucose/100 mL, pH 4.4-4.7, 0.22-0.24% acidity, and 9.6-11.2% alcohol content. The alcohol yield of the Jinhongmi mashes using black, white, yellow koji and improved nuruk were 229.2, 194.5, 238.6 and 229.3 L/ton, respectively. The alcohol yields of Hobak mashes using black, white, yellow koji and improved nuruk were 132.8, 144.4, 141.6 and 167.4 L/ton, respectively. All types of sweet potato soju showed stronger flavor and taste than Kurokirishima (Japanese sweet potato soju). Especially, soju made from Jinhongmi with white koji and Jinhongmi with improved nuruk showed the strongest levels. Flavor components of sweet potato soju included decanoic acid ethylester, dodecanoic acid ethylester, tetradecanoic acid ethylester, hexadecanoic acid ethylester, 9-octadecanoic acid ethylester, and octadecanoic acid ethylester. Although the flavor profiles of Jinhongmi soju, Hobak soju, and Kurokirishima were very similar, the flavor content of Kurokirishima soju was lower. The results of the GC volatile analysis were in good correlation with flavor and taste.

Six different mashing types ((A) $koji$+purified enzyme, (B) $koji$+crude enzyme, (C) $koji$+$nuruk$, (D) $koji$+purified enzyme+$nuruk$, (E) $koji$+crude enzyme+$nuruk$, (F) purified enzyme+$nuruk$) had been established, according to fermentation agents and a mixing rate of rice $makgeolli$, in this study. The alcohol content was the highest in the mashing type (C), which was 13.6%, followed by (D) 13.5%, (A) 13.1%, (B) 12.9%, (E) 12.7% and (F) 12.1%. The reducing sugar content of (A) was the highest with 401.6 mg% and those of (B), (C), (D) and (F) were between 337.3- 380.9 mg%. The alcohol components were found and tended to increase during the fermentation. The oligo-saccharides content was the highest in (D) with 1251.3 mg%, which was followed by (E) 1,219.2 mg%, (C) 1,141.4 mg%, (A) 1,049.9 mg% and 973.8 mg% in (B). The total free amino acid was highest in (B) with 781.4 mg% and followed by (C) 703.2 mg%, (D) 702.6 mg%, (E) 678.7 mg%, (A) 630.4 mg% and (F) 328.7 mg% in order. There were 16 different types of volatile flavor components, in the mashing types (A) and (B), in addition to 15 different types of those in type (C), as well as 14 different types of those in (D), (E) and (F). There were significant differences in the overall preference between the type (A) and (C).
