  • $Kochujang$ is a fermented paste originated from in and $Kochujang$ sauce is a nutritionally and functionally improved version of $Kochujang$ with additions of beef and tonic herbal extracts. The optimization of the ingredient ratios in the manufacturing of $Kochujang$ sauce was investigated using central composite design and response surface methodology. The amount of beef ($X_1$) and the amount of tonic herbal extract ($X_2$) were chosen as the independent variables. The dependent variables consisted of the properties and sensory evaluation scores The examined physicochemical properties included water activity, pH, color, viscosity, and soluble solids. The sensory evaluation attributes were color, flavor, taste, texture, and overall acceptability. Among them, the selected dependent variables were the sauce viscosity ($Y_1$) and the overall acceptability ($Y_2$) of the sauce. The optimal conditions for the independent variables were $X_1$= 9.7% and $X_2$= 14.1%. In addition, the predicted values of the multiple response optimal conditions were $Y_1$= 331000 (cP) and $Y_2$= 7.1 (points), and the actual experimental values were $Y_1$= 3316667 (cP) and $Y_2$= 7 (points).

  • 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.

  • Lupin seed was used to make Meju, the fermentation starter for Korean soybean sauce and paste in substitution for soybean and the fermentation characteristics were compared with those of soybean. Mejus were prepared by in-oculating Asp. oryzae on the cooked whole beans. The dried Mejus were used for making fermented bean sauce and paste by mixing with brine and subsequent ripening for 4 weeks. In general the protease activity and amylase activity-during ripening were higher in lupin seed Meju than those of soybean Meju. The increase in protease activity correlated to the increase in $\alpha$-amino nitrogen content of the fermented paste and sauce. The development of dark-brown color of the sauce during ripening faster with lupin seed Meju compared to soybean Meju. In sensory evaluation the flavor score of lupin seed sauce and paste was slightly lower than that of soybean products but the overall quality of fermented lupin seed sauce was acceptable.

  • This study was conducted to optimize the level of sugar added (20 (control), 15, 10, 5%) during the preparation of soy sauce-salted mushrooms (Pleurotus eryngii) jangachi without affecting the degree of preference. The salinity and sugar content during storage of soy sauce-salted mushrooms (Pleurotus eryngii) jangachi decreased significantly as the level of sugar added decreased. The moisture content was found to increase as the level of sugar added decreased. Additionally, the pH increased, while hardness decreased as the level of sugar added decreased during 3 weeks of storage. The L value (lightness) was not different from that of the control group until the addition of 10% sugar, while the a value (redness) and b value (yellowness) increased. The antioxidant activity of vitamin C content and DPPH radical scavenging activity increased as sugar content decreased. Upon sensory evaluation of mushrooms (Pleurotus eryngii) jangachi, the highest value in appearance was observed for the 5 and 15% treatments, while 5% had the highest flavor value, 15 and 10% had the highest taste values, 10 and 15% had the highest texture values, the control and 5% had the greatest clarification values, and the 15 and 10% groups had the greatest overall acceptance. These results suggest that a sugar level of 15% can be used without significantly affecting the overall acceptance.
