The core ingredient of traditional Korean style soy sauce is soy bean without any wheat or rice incorporated. National brands as well as regional micro-brewed companies constitute the soy sauce market in Korea. The present study investigated the physico-chemical and sensory properties of soy sauces produced by small-scale or mass-production. Additionally, the key physico-chemical parameters sufficiently representing the critical sensory characteristics have been identified. Ten types of soy sauce brewed by the Korean traditional method were selected for the study. Among these samples, seven types were brewed in small-scales in the Gyeonggi-do region whereas the other 3 types were mass-production products of major national brands. The total solid, reducing sugar, salinity, sugar content, amino nitrogen, CIELAB, acidity, and pH of soy sauce samples were measured for the physico-chemical analysis. A generic descriptive analysis was conducted to analyze the sensory characteristics of the samples using six trained panelists. The descriptive panel developed 21 sensory attributes. The data were statistically analyzed using ANOVA, PCA and PLSR. Overall, the micro-brewed products showed significantly higher value of salinity and acidity but lower content of reducing sugar than the mass-production products. The micro-brewed soy sauces elicited stronger fermented flavor, sourness, and bitterness whereas the national brand products elicited stronger alcoholic odor, sweetness and umami taste. Sugar content, acidity, and amino nitrogen showed strong relationships with fish sauce flavor, umami taste, and rich flavor. Salinity was closely related to the overall flavor intensity.

The present study aimed at evaluating effects of traditional sauce type and storage time on shelf-life and flavor compounds of marinated pork cooked by Sous-Vide method. Five different traditional sauces (Meju soy sauce, Brewed soy sauce, Fish-soy sauce, Ishiru fish sauce and Anchovy fish sauce) purchased from Asian countries were used. After marination with the sauces, polyvinylchloride film bags containing the marinated pork samples were cooked using Sous-Vide method for $55^{\circ}C$ for 5 h and $60^{\circ}C$ for 30 min, and were then stored for 8 wk at $10^{\circ}C$. Results showed that the pork samples marinated with the sauces retarded the growth of total plate counts (TPC) during storage. At $8^{th}$ wk storage, TPC counts were significantly lower in all samples marinated with the sauces compared to control (p<0.05). Lipid oxidation level was significantly lower in the T2 (Meju soy sauce) and T6 (Anchovy fish sauce) compared to those of T3 (Brewed soy sauce) and T5 (Ishiru fish sauce) or control after 8 wk storage (p>0.05). Forty volatile flavor compounds were detected from the control and marinated samples at $4^{th}$ wk of storage. The pork marinated with Anchovy fish sauce presented significantly higher amounts of importantly pleasant flavor compounds such as; pyrazines and sulfurcontaining compounds than those marinated with other remaining sauces and control. It is concluded that the marination with Anchovy fish sauce partly improved the shelf-life and increased amounts of pleasant flavor compounds of Sous-Vide cooked pork products during storage in comparison to the other remaining sauces.

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 study made Soy-Sauce-Kimchi and investigated its pH, acidity, microorganism, salinity, chromaticity, viscosity and taste to revive traditional Soy-Sauce-Kimchi using Soy-Sauce instead of salt and to report its fermentation characteristics. As one of studies on traditional Kimchi, it tried for practical use of traditional Soy-Sauce-Kimchi which had been eaten in the middle region of Korea, especially in Seoul but currently has been prepared by only a few people and has disappeared gradually. According to the results of this study, among three groups of Soy-Sauce-Kimchi-I(s1), Soy- Sauce-Kimchi-II(s2) added by 2.5% sucrose and the control group(C), acidity of s2 was sharply increased after 24 hours and 72 hours at $20^{\circ}C$ and $10^{\circ}C$ respectively and there was few difference in salinity by temperature. In the case of s2 group, addition of 2.5% sucrose was considered to lead to increase of salinity. For chromaticity, while the L value and b value became larger after 48 hours, the a value tended to decline. Viscosity of s2 grew after 24 hours at all of $20^{\circ}C$, $10^{\circ}C$ and $1^{\circ}C$ and that was thought to be because propagation of bacteria such as Leuconostoc mesenteriodes following addition of 2.5% sucrose secreted dextransucrose so sucrose was transferred into dextran to increase viscosity. The total number of microorganisms was recorded to be largest after 48, 36 and 72 hours at $20^{\circ}C$, $10^{\circ}C$ and $1^{\circ}C$ respectively and the number of lactic acid bacteria was the largest at $1^{\circ}C$ after 72 hours compared to those at other temperatures. That was considered to be because microorganisms such as Leuconostoc mesenteriodes are psychrotropic lactic acid bacteria. For sensory evaluation, all appearance, chromaticity and odor of C were higher by $3{\sim}4$ points than those of s1 and s2(p < 0.001) and their feel also showed a similar tendency(p < 0.05). Considering the results of sensory evaluation, more researches were needed to overcome difference of taste for Soy-Sauce-Kimchi according to age due to characteristic flavor and smell of soy-source.

This study was carried out in order to analyze the changes in nitrogen containing taste compounds of traditional Korean soy sauce with varying Meju concentrations (Meju-water ratios of 1:4 and 1.3:4) and ripening periods (up to 2 years), and to investigate correlation between sensory characteristics and taste compound contents via contents assay and sensory evaluation of soy sauce samples. Nitrogen compound contents were higher in 1.3:4 than in 1:4 for all nitrogen compounds. Free amino acid contents were highest in soy sauce ripened for 210 days. Among amino acids, glutamic acid was highest concentration. Nucleotides and their related compound contents did not vary with concentrations and were highest in the sample ripened for 210 days. In direct sensory evaluation of soy sauce, overall taste preference showed positive correlation to sweet taste. Likewise, overall taste preference showed positive correlation to umami, nutty, sweet taste in the sensory evaluation of seaweed soup seasoned with soy sauce. Sensory evaluation score was higher in 1.3:4 than in 1:4. According to the correlation assay of taste compound contents and sensory evaluations, nitrogen compounds (such as amino type nitrogen), amino acids (such as glutamic acid, aspartic acid, and lysine, and etc.), nucleotides (such as AMP, IMP, and etc) had significant influence on the sensory characteristics of soy sauce, and therefore we can conclude that these compounds affect the taste and quality of soy sauce.

This study was conducted to investigate the effects of educating 5th graders in elementary school about Korean traditional fermented soy products. The percentage of correct answers from the educated group increased after nutrition education compared to the non-educated group (p<0.001). The perceptions and attitudes regarding Korean traditional fermented soy products increased significantly after nutrition education (p<0.05). Analysis of the preference for Korean traditional fermented soy products based on participation in nutrition education showed that both groups were not significantly different in all categories including soybean paste, soy sauce, and red pepper paste. The investigation on differences in intake frequency of Korean traditional fermented soy products showed that both groups did not display statistically significant differences in all categories including soybean paste, soy sauce, and red pepper paste. These results confirmed that the nutrition education activity program had positive effects in correcting 5th graders' knowledge, perceptions and attitudes regarding Korean traditional fermented soy products. However, it did not significantly affect their preferences and intake frequency. This indicates that short-term education cannot effect changes in preference or actual behaviors. Therefore, continuous nutrition education activities are required.
