The suwey on the consumption pattern of Korean traditional soy sauce and commercial soy sauce was performed. 55.8 percentage of surveyed house makes Korean traditional soy sauce domestically, But its frequency in actual use is lower than commercial soy sauce. The use of Korean traditional soy sauce and commercial soy sauce was different depending on the kinds of food. Korean traditional soy sauce is mainly used for kinds of soup, and commercial soy sauce is predominantly used for hard-boiled foods and Chapchae. Korean traditional soy sauce is known as our typical fermented food and has special flavor. But its main factors of special flavor were not well established yet. So the authors have investigated the main components of Korean traditional soy sauce for its typical taste. Five samples o$.$ere selected from'Kyung-ln'area. The sensory charac teristics of Korean traditional soy sauce itself were very different with that of cooked food added with Korean traditional soy sauce. The hard-boiled mackerel cooked with commercial soy sauce was prefered than Korean traditional soy sauce. And soups and seasoned vegetables cooked with Korean traditional soy sauce were profered. By stepwiEe regression analysis and correlation analysis, sensory overall acceptability mainly depends on specific gravity, salt content and amino nitrogen content (R'=0.94). And total nitrogen content was highly coirelated with overall acceptability (r=0.91).

We identified volatile components of traditional Korean soy sauce and soybean paste which had been manufactured with the same traditional Meju with a view to improving the quality of traditional Korean soy sauce and soybean paste. All of the volatile components were extracted by simultaneous steam distillation-extraction (SDE) apparatus. To obtain more detailed information, whole volatile components were separated into fractions. The volatile components of the whole and of each fraction were identified by GC-mass and Kovat's retention index. Sixty two and eighty six components were identified in traditional Korean soy sauce and soybean paste, respectively. Many aroma components of traditional Korean soy sauce differ from those of traditional Korean soybean paste. It was confirmed that many aroma components of traditional Korean soy sauce and soybean paste are completely different from those of Japanese fermented soy sauce (Shoyu) and soybean paste (Miso).

This study investigated conditions necessary for factory production of traditional Korean soy sauce flavors, using Bacillus licheniformis SSA3-2M1. We determined whether the flavors were good or bad by comparing sensory evaluation values and the contents of the main taste components of traditional Korean soy sauce with those of the manufactured soy sauce. The soy broth was cultured by Bacillus licheniformis SSA3-2M1. By providing from 1/3 vvm to 2/3 vvm of air, and a culturing time of 412 hours at 30$^{\circ}C$, we produced the taste of traditional Korean soy sauce; moreover its PH was in the PH range of traditioal Korean soy sauce. The distributions of the main taste components and the amino acids, free sugars, and organic acids in the manufactured soy sauce were similar to tradituioal Korean soy sauce.

This study was carried out in order to investigate general characteristics, sugars and organic acids contents of Korean traditional soy sauce, and to find out possibility of high quality soy sauce production in a short period through high concentration soy sauce making. In this study, we prepared three different types of soy sauce, low concentration soy sauce (Chungjang), high concentration soy sauce and Kyupjang, high quality traditional Korean soy sauce. pH of soy sauce were $4.46{\sim}4.90$ and did not show difference among three samples. Titratable acidity, buffering power and total free acid content were the highest value in Kyupjang. Kyupjang showed the highest contents of salt and pure extract. As the ripening period increased, the salt content increased in Chungjang samples, but decreased in Kyupjang. Reducing sugar contents of Kyupjang, high concentration soy sauce and low concentration soy sauce were 1.13%, 0.76% and 0.53%, respectively. Free sugar in soy sauce were analyzed maltose, glucose, galactose and fructose. Total free sugar content was highest in high concentration soy sauce, however, contents of glucose and fructose were higher in Kyupjang than in Chungjang samples. Galactose was the main free sugar in Chungjang, but glucose was in Kyupjang. Among identified volatile organic acid, acetic acid was present in the highest concentration, and volatile organic acid content was highest in the high concentration soy sauce at 150 days. 20 nonvolatile organic acids were detected in Korean traditional soy sauce. Succinic acid, lactic acid and 2,5-pyridine dicarboxylic acid were the main nonvolatile organic acid in soy sauce.

We characterized the character impact compounds of flavors of the fermented Korean soy sauce manufactured with both the traditional and the improved Meju made with different strains. The whole flavor samples were obtained by extracting each volatile flavor phase from both the traditional and the improved soy sauce. To get more detailed information, each whole volatile flavor was further fractionated into the basic, acidic, phenolic and neutral fractions. Each separated peak from the whole and fractionated flavor samples on gas chromatogram was identified by GC/MS and Kovat s retention index, and likewise the aroma of each peak was investigated by a sniffing test with the exercised panel. We were able to identify 15 groups of ingredients with the characteristic soy sauce aroma from the soy sauce made with the traditional Meju and 6 groups from the soy sauce manufactured with the improved Meju made with Aspergillus oryzae. The character impact compounds the two soy sauces were different from each other.

본고는 '장 담그기'라는 구체적 사례를 통해 무형유산으로서 음식의 전승성이라는 문제를 살펴보고, 음식관습을 지속 유지시키는 원동력이 무엇인가에 대한 답을 모색하기 위해 마련되었다. 이를 위해 필자는 서로 다른 세 가지 유형의 구체적 사례를 통해 '장 담그기'의 전승양상에서 나타나는 지속과 변화를 살펴보았다. 첫 번째 사례는 '장 담그기'의 전과정을 직접 수행하는 경우다. 두 번째는 구입한 메주로 '장 담그기'를 실천하고 있는 사례다. 세 번째 사례는 음식에 관한 이념을 공유하는 사람들끼리 계를 조직하여 매년 장을 담그고 '씨간장'을 적립해가는 경우로, 매우 새로운 음식공동체의 출현을 엿볼 수 있다. '장 담그기'전승에서 변화를 이끌어내는 요인은 도구와 기술, 생산과 소비, 그리고 음식공동체의 변화라 할 수 있다. 이러한 변인들 때문에 오늘날 '장 담그기'전승은 실제 상당 부분 변화되고 있지만, 면담대상자들은 전통적 방식으로 만든 장맛이 유지되는 한 본인들의 '장 담그기'전통은 지속된다고 믿고 있었다. 따라서 '장 담그기'가 계속 전승되고 유지되기 위해서는, 장맛을 기억하고 향유할 줄 아는 '맛의 공동체'의 지속에 관심을 가질 필요가 있다.

This study was performed to investigate the changes of amino nitrogen, total amino acids, free amino acids, and color of Korean traditional soy sauce (kan-jang) during the ripening and storage for 12 months and the characteristics of the changes. All of the preparation methods for soy sauce followed the recommendations of the Korea Food Research Institute. The components of soy sauce were analyzed at 0,6, and 12 months. The contents of amino nitrogen of soy sauce were significantly higher than that of soybeans or meju (soybean cakes) at the initial stage of storage (p<0.05), and decreased during the storage. The content of total amino acids of soybean sauce was significantly lower than that of soybeans, and the content of free amino acids was higher than that of soybeans (p<0.05). The contents of total and free amino acids decreased in soy sauce after 12 months of storage (p<0.05). The composition of total and free amino acids and their ratios of soy sauce were changed during the storage. The ratios of free to total amino acids of soybeans, meju, and soy sauce were 0.8％, 17.3％, and 53.1-59.8％, respectively. Glutamic acid, which represents the savory taste, was detected the most abundantly in soy sauce during the storage. The ratios of free to total amino acids of glutamic acid were 42.9-59.5％ in soy sauce. Lightness of Hunter color of soy sauce decreased over time (p<0.05). This study indicates that the ratios of free to total amino acids of soy sauce were much higher than those of soybeans, although its contents of total amino acids were much lower than those of soybeans. This study also indicates that this comes from the preparation and fermentation of meju. It was suspected that the organoleptic characteristics of soy sauce derived from the amino nitrogen, amino acids, and color might be inferior over 1 year of storage time. However, more detailed research should be conducted to interpretate this characteristics more accurately.
