  • Herb soy sauce was prepared by extracting rosemary, lemon balm, spearmint and peppermint at a low temperature in fresh soy sauce. The antioxidant and physicochemical properties of herb soy sauces were examined. Herb soy sauces were prepared by adding 2.5% (w/v) of herbs to fresh soy sauce at 60℃. The total polyphenol, DPPH%, ABTS% increased with extracting time but five minutes extraction with sufficient antioxidant herb soy sauce could be prepared. The antioxidant powers of herb soy sauces were higher in lemon balm extract, and the rosemary extract showed the lowest. Soy sauces added with herbs had lower pH and salinity (p<0.05) and higher sugar content than without herbs. The colorness according to the type of herbs showed significant difference.

  • 3-Monochloro-1,2-propanediol(3-MCPD) was analyzed in soy sauce products commercially available in Korea. A total of 24 samples were collected and 3-MCPD was determined by GC/MS. Sources of 24 samples were classified by manufacturing methods as naturally brewed(NB), acid hydrolyzed (AH) and mixed (M = NB + AH) soy sauces. 3-MCPD was not detected in NB soy sauce products (< 0.01 ppm, mg/kg) whereas AH and M soy sauce products showed a wide range of 3-MCPD contamination (0.0l ∼ 2.038 ppm). The contaminated levels of 3-MCPD in soy sauce products were higher than the permissible or tentative permissible level of 3-MCPD in both European Community (0.02 ppm) and Korea (0.3 ppm). These data suggest that 3-MCPD levels contaminated in soy sauce products in Korea were shown to be too high and should be reduced to as low a level technologically feasible to protect Korean from the exposure to toxic chemical, 3-MCPD.

  • Soy sauce has a long history used as a food ingredient. However, hydrolyzed vegetable protein, mono-sodium glutamate, starch syrup, and fructose are added to soy sauce during fermentation for the taste and flavor of product. But consumers have been reluctant to the taste of these artificial additives. In this experiment, anchovy sauce was used to prepare soy sauce to enhance the quality and brine was used as a control. To evaluate the quality of soy sauce added with anchovy, total nitrogen (TN) and soluble nitrogen contents, total soild contents, total sugar reducing sugar. lactic acid content and protease activity were monitored during fer-mentation. Total microbial numbers and lactic acid bacteria were not significantly changed among the cases. Aerobic and anaerobic microorganisms. and lactic acid bacteria were not significantly changed among the cases we studied, For the total sensory test, it was also estimated that the cases using anchovy sauce were superior to the control. From the results mentioned above, we could obtain shorter fermenation period as well as the quality improvement in the case of using anchovy sauce instead of salty water in the fermented soy sauce production.

  • To develop a method appropriate for mass production in a factory, we manufactured soy sauce with Bacillus species SSA3-2M1 and fused ST723-F31 at $30^{\circ}C$ with aeration of 1/3 vvm for 40 days. The flavor components extracted from the manufactured soy sauce were fractionated to neutral, acidic, basic and phenolic fraction and identified by GC-mass. Among the 60 kinds of identified flavor components, 16 and 23 components were detected in traditional Korean soy sauce and soybean paste, respectively. There were three peak regions that smelled like soy sauce with the GC sniffing test of flavor components and 2, 6-dimethyl pyrazine, benzaldehyde, 2-methoxy phenol, phenol and benzeneethanol which were identified as character impact compounds of traditional Korean soy sauce and soybean paste were identified in the region that smelled like soy sauce. It is therefore considered possible to achieve mass production of soy sauce with standard quality by Bacillus species SSA3-2M1 and fused ST723-F31 in the factory.

  • This study attempts to find an optimized amount of soy sauce, sugar and boiling time for the best soy-sauce-based Teriyaki sauce, using the Response Surface Methodology(RSM). The following is the summary of the study. The amount of soy sauce, sugar and boiling time were set as independent variables to study the sensory characteristics of soy sauce. As a result, significant differences in appearance, taste and overall acceptance of soy sauce were observed. In appearance, boiling time was the most effective factor, followed by sugar and soy sauce. The taste was affected most by sugar, followed by boiling time and soy sauce in order. Overall acceptance, ranked in ascending order, is as follows : soy sauce, boiling time and sugar. So based on the study, the best results are: soy sauce 1,182.76 g - 1,210.11 g, sugar 843.97 g - 851.17 g, boiling time 174.49 mins - 181.46 mins. Among them, optimum points are: soy sauce 1,196.44 g, sugar 847.57 g, boiling time 177.98 mins.

  • This study was performed to investigate the changes of Bacillus sp. of traditional Korean soy sauce (kan-jang) and soybean paste (doen-jang) during the ripening and storage for 12 months. All of the preparation methods for soy sauce and soybean paste followed the recommendations of the Korea Food Research Institute. The soy sauce and soybean paste were analyzed at 0, 6, and 12 months. The numbers of Bacillus sp. of meju (soybean cakes) or soy sauce and soybean paste at the initial stage were significantly higher than those of soybeans (p<0.05). The number of Bacillus sp. increased in soy sauce and soybean paste after 12 months of ripening and storage. This study indicates that this comes from the preparation and fermentation of meju. It is suspected that the organoleptic characteristics of soy sauce and soybean paste might be inferior over 1 year of storage time. Therefore, more research fur overall microbiological quality changes of soy sauce and soybean paste during the storage period should be conducted to interpretate this characteristics more accurately.

  • This paper investigates the transmission of food as an intangible cultural heritage and tries to answer what maintains and promotes traditional food culture, though researching into the specific example of 'making traditional soy sauce.' For that, I chose three different cases to research into the continuation and change in the transmission of traditional soy sauce making. The first instance is when the informant makes traditional soy sauce by herself. The second example is when the informant makes traditional soy sauce with ready-made soybean lumps.The last case is that people sharing the same ideology about food organize a community('kye') and make soy sauce together each year and reserve 'seed soy sauce.' This is a new type of food community. The changes in tools and skills, in production and consumption, and in food communities caused changes in the transmission of traditional soy sauce making. Because of these factors, the way of making traditional soy sauce is changing a lot. The informants, however, believed that the tradition of 'making soy sauce' will last, as far as the taste of soy sauce made in the traditional method stays the same. Therefore, we need to make an effort to sustain communities of people who remember and enjoy the taste of traditional soy sauce in order to keep the tradition of making traditional soy sauce.

  • Korean soy-sauces were orepared by the ordinary and impreved method and its analyses on the organic acid. The results obtained is as following: 1. In analysing general components of prepared soy-sauce, total acid, volatile acid and non-volatile acid were found more in improved soy-sauce than in ordinary soy-sauce. 2. Volatile organic acid were analysed by gas-chromatography method. As a result, the followings was attained: a) In the ordinary soy-sauce, formic acid, acetic acid, propionic acid, and butyric acid were detected. Butyric acid was in the highest amount and then propionic acid, acetic acid and formic acid are followed in the order. b) In the improved soy-sauce, formic acid, acetic acid, propionic acid and butyric acid were detected. Acetic acid was in the highest amount and then propionic acid, butyric acid and formic acid are followed in the nrder. 3. Non-volatile organic acid were analysed by paper partition chromatography method. As a result, the followings were attained: a) Lactic, glutaric, fumaric, malonic, malic, glycolic, oxalic, tartaric, and succinic acid and two unknown spots were detected in ordinary soysauce. Lactic acid was in the highest amount and then succinic, glycolic, oxalic, tartaric, glutaric, malic, fumaric and malonic acid are followed in the order. b) Lactic, glutaric, malonic, malic, glycolic, tartaric, succinic and tgalacturonic acid and two unknown spots were detected in the improved soy-sauce. Lactic acid was in the highest amount and then succinic, glycolic, malic, glutaric, tartaric, galacturonic and malonic acid are followed in the order. 4. ${\alpha}-keto$ acid were analysed by paper partition chromatography. As a result, the followings were attained: Pyruvic acid and ${\alpha}-keto$ glutaric acid and an unknown spot were detected in the ordinary and improved soy-sauce. Pyruvic acid was in the highest amount and then ${\alpha}-keto$ glutaric acid are ollowed in the order. 5. Stale flavor in the ordinary soy-sauces seems to be partly affected by butyric acid and propionic acid. 6. Substances influencing taste, such as lactic acid and succinic acid, were found more in improved soy-sauce than ordinary soy-sauce.

  • 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).
