  • Natural colorant extracts were obtained by extraction from tumeric root, gardenia seeds, mugwort and green tea using water, methanol, ethanol and acetone as extractants at room temperature for 3 hours under shaking condition(180rpm) with liquor ratio(solid:solvent; 1:100). The main pigment components of tumeric root, gardenia seeds, mugwort and green tea are known to be curcumin, crocin, chlorophyll b and epigallocatechin gallate, respectively. The effects of the kind of extractant and pH on the color characteristics of natural colorant extracts were investigated. The solubility parameters of pigment components were determined to find adequate extractant. The solubility parameters of curcumin, crocin, chlorophyll b and epigallocatechin gallate were found to be 27.85, 29.40, 19.48 and $37.97(J/cm^3)^{1/2}$. As expected, solvents that have a solubility parameter similar to that of pigment component were generally found to be effective to obtain pigment extracts having high visible absorbance(A). The extract(pigment/solvent) with high visible absorbance was generally found to have low $L^*$(lightness) and high Chroma($C^*$, purity).

  • Daqu, a traditional fermentation starter, has been used to produce attractively flavored foods such as vinegar and Chinese liquor for thousands of years. Although Bacillus spp. are one of the dominant microorganisms in Daqu, more precise information is needed to reveal why and how Bacillus became dominant in Daqu, and next, to assess the impact of Bacillus sp. on Daqu and its derived products. We combined culture-dependent and culture-independent methods to study the ecology of Bacillus during Daqu incubation. Throughout the incubation, 67 presumptive Bacillus spp. isolates were obtained, 52 of which were confirmed by 16S rDNA sequencing. The identified organisms belonged to 8 Bacillus species: B. licheniformis, B. subtilis, B. amyloliquefaciens, B. cereus, B. circulans, B. megaterium, B. pumilus, and B. anthracis. A primer set specific for Bacillus and related genera was used in a selective PCR study, followed by a nested DGGE PCR targeting the V9 region of the 16S rDNA. Species identified from the PCR-DGGE fingerprints were related to B. licheniformis, B. subtilis, B. amyloliquefaciens, B. pumilus, B. benzoevorans, and B. foraminis. The predominant species was found to be B. licheniformis. Certain B. licheniformis strains exhibited potent antimicrobial activities. The greatest species diversity occurred at the Liangmei stage of Daqu incubation. To date, we lack sufficient knowledge of Bacillus distribution in Daqu. Elucidating the ecology of Bacillus during Daqu incubation would enable the impact of Bacillus on Daqu to be accessed, and the quality and stabilization of Daqu-derived products to be optimized.

  • This study was conducted to investigate the causes of burn and emergency cares taken on the spot for the burn patient. Study population included 161 burn patients admitted to 2 university hospitals and 1 general hospital in Taegu from November 1, 1987 to April 30, 1988. Patients or guardians were interviewed with a structured questionnare. Out of 161 burn patients 111(68.9%)were males and 50(31.1%) females. Preschool children of 1-4 years old accounted for 29.8% of the total patients. Burns of children under 15 years of age took place at home in 91.0%, while 48.3% of burns of adult (15 years and over)males occurred at the working place, and 68.0% of adult females occurred at the home. Out of total burns occurred at home 39.8% took place at kitchen/dining room and 24.1% in the room. The most common cause of burns in children was the boiling water or hot food (74.3%). In adults the common causes were electrical burn(22.4%), hot water or food(19.0%) and explosion(12.1%) for males, and hot water or food(32.0%) and explosion (20.0%) for females. Common emergency cares for the burn taken on the spot were undressing(64.6%), pouring Soju(liquor)(13.7%), and pouring cold water(5.0%). There were a few cases who applied ash, soy or salt. To prevent burn, it is recommended to remodel the traditional kitchen and coal-briquet hole, to strengthen the safety control of LP Gas and LN Gas supply, to educate the public for the handling method for such gases, to strengthen the occupational safety control, to improve the safety device for the electric wire and socket, and to limit the temperature of hot water at home and public baths.

  • In order to determine the optimal condition for making Yugwa (one of the Korean traditional cake) the textures in various conditions were studied by sensory test and texturometer. The changes of texture and fat content in the cake were measured along the period of storage. The results were as follows: (1) The cake were classified in 3 groups according to the leavening agent used in the procedure, namely refined rice wine (W), distilled liquor (L) and yeast group (Y). It was the refined rice wine group that had been 'the best' by sensory test. Its brittleness $(1.40{\pm}0.27)$ was higher than those of L and Y. (2) Crispness measured by bend test prior to soaking into syrup were 1.19, 1.23 and 1.63 in W, L, Y, respectively. (3) Chemical composition (%dry basis)) of Yugwa leavened with W included 9.3 of moisture, 1.3 crude protein, 6.7 crude lipid, 66.4 carbohydrate and 16.3 crude ash. (4) Brittleness decreased gradually along the period of storage while the rancidity increased. From the 40th days of storage, the change of brittleness and rancidity were marked as well as the scores of sensory test decreased significantly. (5) Content of linoleic acid in Yugwa decreased along the period of storage from 52.5% of total fatty acid on the first day to 10.9% on the 50th days Main fatty acids in Yugwa were oleic acid, palmitic acid and stearic acid, all of which were also decreased in content along the period of storage. One remarkable change was the appearance of an unknown fatty acid with 19.54 of retention time, in 50% of total fatty acid, on the 50th day of storage.

  • As people know how to brew a wine from fruits and cereals, they continued to develope various wines good to their taste. Korean wines are also ones made from cereals and they have long been eager to improve the delicate taste. They used to drink Takju, raw rice wine, made from nonglutinous rice and Nuruk, a kind of yeast starter. During Koryo Dynasty, Soju a liquor was imported from Won(the Chinese dynasty). Nowadays this traditional folk wine, which had been developed variously and drunk all over the country, is decreasing year after year. The purpose of this study was to review on the wines ; its kinds, raw materials, brewing method, manufacturing utensils, measuring units and devices and the terms for wine making based on 20 documents published in 1600, in the middle of Yi dynesty. The results of review were as follows. 1. There were 121 kinds of wines at that time in Korea. 2. Among the raw materials for wines, major materials were glutinous rice, nonglutinous rice, wheat flour, wheat, mung bean, and black soybean. And minor materials were pepper corn, Lycium chinenisis, cinnamon, pine needles, pine nuts, jujube, mugwort leaves, lotus leaves, pine corn, pine bud, chrysanthemum, pine flowers, honey, Acanthopanox seoultenses, bamboo-root, marrowbone of blak cow, sweet flag, Ciprus noblis, Saurea lappa, honey suckle, Tricho santhes, azalea, the leaves of the paper mulberry, and bark of chungum tree. 3. There were several kinds of wines such as a wine without using Nuruk, a wine made from glutinous rice, nonglutinous rice, or glutinous and nonglutinous rice with flour. 4. There were several brewing methods for wines such as a wine boiled with ring rice cake, a wine brewed with loaves of rice cake, a wine brewed with hard boiled rice, a wine brewed with rice gruel, and a wine brewed with powdered rice gruel. 5. There were 23 kinds of utensils including measuring devices for weight and volume.

  • Objectives: Juknyeok (JN) is natural liquor extracted from bamboo stems (Phyllostachys bambusoides) and has been used as a traditional Korean medicine for improving vascular function, blood glucose, and treating stroke. Until now, the JN's lipid-lowering effect and underlying mechanism in adipocytes are poorly understood. The aim of this study was to scrutinize the effect of a standardized commercial JN on lipid accumulation during the differentiation of 3T3-L1 preadipocytes. Methods: Lipid and triglyceride (TG) accumulation in differentiating 3T3-L1 preadipocytes were measured by Oil Red O staining and AdipoRed assay, respectively. Cell count analysis was used to ascertain 3T3-L1 cytotoxicity. Immunoblotting and Reverse transcription polymerase chain reaction analysis were used to assess protein and messenger RNA (mRNA) expression levels in 3T3-L1 cells, respectively. Results: Treatment with JN at 25 𝜇l/ml after pH calibration with 6.35 significantly reduced lipid and TG accumulation in differentiating 3T3-L1 preadipocytes without significant cytotoxicity. On mechanistic levels, JN markedly suppressed protein expression levels of CCAAT/enhancer-binding protein (C/EBP)-𝛽 and fatty acid synthase (FAS) during the differentiation of 3T3-L1 preadipocytes. However, JN did not affect the protein expression levels of C/EBP-𝛼, peroxisome proliferator-activated receptor-𝛽/𝛾, and phosphorylation levels of signal transducer and activator of transcription-3/5 in differentiating 3T3-L1 preadipocytes. JN also reduced leptin mRNA expression levels in differentiating 3T3-L1 preadipocytes. Conclusions: JN at 25 𝜇l/ml lowers lipid accumulation and TG content in differentiating 3T3-L1 cells, mediated through the reduced expression levels of C/EBP-𝛽 and FAS.

  • With the steady growth in the scale of the domestic traditional liquor industry, the interest in makgeolli has also been increasing. As the demand for makgeolli increases, interest in manufacturing differentiated makgeolli by adding additional raw materials such as fruits is increasing. In this study, makgeolli with low storage persimmon juice was manufactured, and the sweet taste of persimmon was imparted without adding sweeteners. Unsweetened, high-quality persimmon makgeolli with an alcohol content of 15% or more was manufactured and its quality characteristics were analyzed. Yeast was selected after producing fermented yeast by treating domestic isolated yeast and commercial yeast. Upon producing fermented yeast, persimmon makgeolli was manufactured by varying the amount of persimmon juice added to the fermented yeast. As a result of analyzing the quality characteristics of persimmon makgeolli, the pH was 4.02-4.25, the total acid (citric acid, %) was 0.30-0.43, the amino acidity (glycine, %) range was 0.05-0.15, and the alcohol content (%) was 15.64-18.48.(p<0.05). Reducing sugar (%) was 1.82-12.68 and total sugar (%) was 1.41-10.42, exhibiting a tendency to increase as the amount of reducing sugar and total sugar and the amount of juice added increased (p<0.05). Considering the sensory characteristics, a sample with 50% persimmon juice added showed a significantly higher residual sugar content, and the residual sugar content had a positive effect on the sensory characteristics. Therefore, 50% persimmon juice was added when making persimmon makgeolli. It is suitable for high-quality, non-sweetened persimmon makgeolli that preserves the taste of persimmon, which suits the consumers'taste.
