The purpose of this study was to determine the possibilities of Korean fermented sauces including red pepper paste, soybean paste, soy sauce, and vinegar as ingredients for Western cuisine. Western cuisine professionals from US and Europe were interviewed for their experienced opinions. To classify the categories, the selected statements were given to other groups of foreign chefs, Korean cuisine professionals and students majoring culinary arts. The first category pointed out that Korean fermented sauces are healthy with 'umami' taste using only natural ingredients. They believe it has high possibilities of matching with many of other foods and also has unique tastes. Korean cuisine professionals were mostly occupied in this category. The second category had negative opinions matching with Western cuisines since Korean fermented sauces are rough and have a strong taste & smell. This category had many Western cuisine professionals. The last category was composed of mainly students majoring in culinary arts. They pointed out that Korean fermented sauces use natural ingredients and have a unique flavor with long-term shelf life. Use of Q methodology was significantly different from previous studies researched by quantitative methods especially for the Korea food service industry.

Fifty three microbes, mainly fungal genera, were isolated from sixteen Mejus of different region. From those collected isolates, Meju was manufactured and assayed for the activities of amylase and protease. Correlations between sensory evaluation and color measurement were investigated with Kanjang (soy sauce) prepared by each pure inoculation. Color of Kanjang was quite various depedning on fungal genera, but the taste was not quite related with the activity of amylase or protease. This fact might mean that taste of Kanjang depended on the complicate mechanistic action of enzyme for the substrate involved in the soybean hydrolysis. Thus, the taste of Kanjang origenated from Korean traditional Meju seems to belong to complex flora of participated fungal genera as well as Bacillus. sp.

Changes of pH, acidity, pretense activity and microorganism on Korean traditional seasonings using soy sauce (T1), red pepper paste (T2) and soybean paste (T3) were investigated during storage at $1{\pm}1^{\circ}C$ for 21 days. The pH and pretense activity of soybean paste were significantly (p<0.05) higher compared to those for soy sauce and red pepper paste during storage. The acidity of red pepper paste were significantly (p<0.05) higher compared to those for soy sauce and soybean paste at 1, 7 and 14 days of storage. The total plate counts and Lactobacilli spp. of soy sauce were significantly (p<0.05) lower compared to those for soybean paste and red pepper paste during storage. The Escherichia coli of red pepper paste and soybean paste were not detected during storage.

The antioxidative effect of doenjang (fermented soybean paste) and onion added in the seasoned pork, bulgogi was evaluated and the optimum mixture ratio of ingredients in seasoning sauce has been established using mixture experimental design (MED). When the seasoned pork, bulgogi was prepared with soy sauce 12% (control), doenjang 9% (in replacement of soy sauce 9%) added group (DG), and doenjang 9% and onion 33.4% (in replacement of water 33.4%) added group (DOG), and stored at $-25^{\circ}C$ for 6 months, the peroxide value (POV) and thiobarbituric acid (TBA) value of control, DO, and DOG were all lower than that of control from the initial stage of storage. The antioxidative effect of seasoned pork was found to increase with the replacement of doenjang in seasoning sauce for pork bulgogi. Moreover, antioxidative effects in DOG increased more synergistically. Therefore, the lipid oxidation stability of pork bulgogi was improved by the addition of doenjang and onion onto the seasoning sauce. The optimum mixture ratio of seasoning sauce for pork bulgogi followed up by the MED was found to be doenjang 7.10%, soy sauce 9.46%, onion 19.72%, and water 42.58% with excellent sensory quality.

The “Jeungbosallimgyeongje” was literature reviewed about the manufacture of Korean sauces. Furthermore, in order to investigate the changes made by time period, other literatures, “Eumsigdimibang(1670s)”, “Sallimgyeongje(1715)”, “Gyuhapchongseo(1815)” and “Choson­mussangyorijebeop(1930)”, were compared. The ingredients mentioned included soy beans, flour, barley, elm trees, red beans and blue beans, etc. In addition, the shapes and sizes of dried soybean paste brick were varied. “Manchojang”, which designated the kind of hot pepper paste, appeared in this book for the first time. During its manufacturing process, it was characteristic to add dried bean paste, sea kelp and fish to produce a novel and higher quality product. From the above mentioned books, we found out that Koreans used only the soybeans and Chinese a mixture of buckwheat, flour and barley in addition to soybeans to make their traditional sauces. According to the“ Gyuhapchongseo” , there was a slight difference in ingredients to add for the manufacture of fish sauce, but the manufacturing methods and the one year period needed for maturing the ingredients were the same.. However, in the “Chosonmussangsinsikyrijebop”, fish sauce and meat sauce were classified separately and their manufacturing methods were different as well. In conclusion, the ingredients of used for the sauces recorded in “Jeungbosallimgyeongje” were various and at first hot pepper sauce made from “Manchojang” appeared and additionally red peppers were added to five kinds of Korean paste and red pepper powder were added to two kinds of Korean paste. The manufacturing method of the sauces changed according to time period, for example, only soybean has been used in Korean traditional sauces and other ingredients used as for Chinese ones eventually disappeared.

Among the many foods, it is hard to find perfect food with nutrition and functionality like beans. Korean food culture is the main ingredient of korean culture, kochujang, soybean paste, and soy sauce, and processed soybean tofu is the main ingredient. Soybean meets high quality protein and fat, and it has excellent results in prevention and treatment of all kinds of diseases. Soybean food is becoming a new generation health food. In countries where animal protein intake is low, soybean is used as a protein source instead of animal protein. Tofu, a processed food, is a complete food with high digestibility. In order to publicize the superiority of soybean nutritional value, Tofu processing and powder were investigated by observing the size, shape and characteristics of bean powder using domestic soybeans and imported soybean, and the variation of the amount of coagulant.

Aspergillus is an important fungal genus used for the fermentation of Asian foods; this genus is referred to as koji mold in Japan and China. A. oryzae, A. sojae, and A. tamari are used in the production of miso and shoyu in Japan, but a comprehensive taxonomic study of Aspergillus isolated from Meju, a fermented soybean starting material for traditional soy sauce and soybean paste in Korea, has not been conducted. In this study, various Aspergillus species were isolated during a study of the mycobiota of Meju, and the aspergilli were identified based on phenotypic characteristics and sequencing of the ${\beta}$-tubulin gene. Most strains of Aspergillus were found to belong to the following sections: Aspergillus (n = 220), Flavi (n = 213), and Nigri (n = 54). The most commonly identified species were A. oryzae (n = 183), A. pseudoglaucus (Eurotium repens) (n = 81), A. chevalieri (E. chevalieri) (n = 62), A. montevidensis (E. amstelodami) (n = 34), A. niger (n = 21), A. tamari (n = 15), A. ruber (E. rubrum) (n = 15), A. proliferans (n = 14), and A. luchuensis (n = 14); 25 species were identified from 533 Aspergillus strains. Aspergillus strains were mainly found during the high temperature fermentation period in the later steps of Meju fermentation.

The purpose of this study was to assess the qualities of cook/chilled soy sauce-glazed soybean curd with various packaging conditions as a trial to develop health-oriented convenience foods. The effects of three packaging methods, linear low density-polyethylene (LLD-PE), top sealing, and modified atmosphere packaging(MAP) on the shelf-life of HACCP-based cook/chilled soy sauce-glazed soybean curd were evaluated during 20 days of chilled storage in terms of time-temperature, microbiological (total aerobic plate count, psychrotrophic plate count, coliform, and fecal coliform count), chemical(pH and peroxide value(POV)), and sensory evaluation. The results of microbiological and chemical analyses were within the limits of the microbial and chemical standards for all phases after cooking. No significant differences were detected in microbial counts of the samples for all three packaging methods. However, sensory evaluation indicated that the top sealing and MAP methods showed a longer shelf-life than LLD-PE packaging. Recommended shelf-life of the product was 12 days for LLD-PE packaging, and 16 days for both top sealing and MAP. In conclusion, MAP was considered as the most effective packaging method for assuring microbial and sensory quality of this cook/chilled product.

We investigated changes in the physiochemical quality of sailfin sandfish sauces fermented with two kojis during long-term storage at room temperature. Four fish sauces, including a control, were prepared by salt-fermentation with soybean koji (S-koji) or rice koji (R-koji) after autolysis. During storage, for 12 months, the color and levels of amino acids, total volatile base nitrogen (T-VBN) and organic acids but not moisture, salt or total nitrogen levels or pH differed markedly according to fish sauce type. The total nitrogen level was highest in S-koji, but there was no difference in the rate of increase in amino acid levels among the four fish sauces during storage. The T-VBN, of autolysis and S-koji were significantly higher than those of the control and R-koji during the entire storage period (P<0.05). The initial organic acid level did not differ among the four fish sauces, whereas it was notably higher in R-koji than in the other sauces at the end of storage. Hunter L, a and b values decreased in all fish sauces with increasing storage time. In conclusion, soybean koji may enhance the levels of nitrogen compounds as well as T-VBN in fish sauce, while rice koji reduced the formation of excess T-VBN and increased organic acid levels during storage at room temperature.

Soy sauce, a basic ingredient in Asian cuisine, is made of fermented soybeans, salt, water, and barley or wheat flour. The sensory characteristics of soy sauce are not only determined through its main ingredients but also by various flavor compounds produced during the fermentation process. This study was conducted to identify the sensory attributes of five different commercial soy sauce samples that differ in Meju types (traditional Meju or modified Meju) and usage types. Thirty three sensory attributes, including appearance (1), odor (16), flavor (14), and mouthfeel (2) attributes, were generated and evaluated by eight trained panelists. The collected data were analyzed by analysis of variance and principal component analysis. There were significant differences in the intensities of all sensory attributes among the soy sauce samples. Soy sauce made with traditional Meju had high intensity of fermented fish, beany, musty odors and salt, Cheonggukjang, fermented fish flavors. Whereas two soy sauces made with modified Meju were strong in alcohol, sweet, Doenjang, roasted soybean flavors. Two soy sauces for soup made with modified Meju had medium levels of briny, sulfury, fermented odors and bitter, chemical flavors and biting mouthfeel characteristic.
