  • 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 contents of organic acids in traditional and modified fermented foods were compared, and propionic acid produced during fermentation was investigated. Organic acids in traditional and modified soy sauces were lactic acid, acetic acid, citric acid, formic acid, succinic acid and oxalic acid while propionic acid was found in traditional soy sauces only. Similarly, lactic acid, acetic acid, citric acid, oxalic acid, formic acid, succinic acid and propionic acid were found in traditional and modified soy paste. The organic acids in traditional and modified kochujang were citric acid, acetic acid, formic acid, lactic acid, malic acid, oxalic acid and succinic acid while propionic acid was not found in modified kochujang. The major organic acid in persimmon and commercial (fermented) vinegars was acetic acid. Propionic acid was uniquely found in persimmon vinegars. Also, content of tannic acid in persimmon vinegars was 366.9 ∼ 909.8 mg%.

  • This study was carried out in order to analyze the changes in general compounds and sugars 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). Along with ripening period, pH decreased and titratable acidity, total acidity and crude protein contents increased, which were higher in 1.3 : 4 than in 1.4. Buffering power increased significantly with increasing ripening period. Crude fat content was higher in 1.3 : 4 than 1 : 4. Moisture content decreased and pure extract content increased significantly with increasing ripening period, which was high in 1.3 : 4. Salt contents increased with increasing ripening period, but decreasd in soy sauce ripened for 2 years. As the result of sugar analysis, reducing sugar showed slow increase with increasing ripening period. Among detected free sugars, galactose was present in the highest concentration and the rest were in the sequence of glucose, fructose. Total free sugar content was highest in soy sauce ripened for 150days in 1 : 4 and 210 days in 1.3 : 4.

  • The main purpose of this study was to perform a literature review regarding bibimnaengmyeon (cold buckwheat noodles mixed with sauce)-related recipes. To conduct this research, we analyzed recipe data published in Korea from the 1800's to the 1980's. The research was conducted by content analysis and literature review. The documents used in the research were 30 books (dictionaries and recipe books). A total of 37 bibimnaengmyeon-related recipes were identified. The results of the analysis of documented data published within the last 200 years showed two different types of main ingredients for bibimnaengmyeon-related recipes; noodles based on buckwheat flour, and noodles based on wheat flour. Additionally, the bibimnaengmyeon-related recipes were divided according to the sauce; 1) noodles mixed with red pepper sauce and 2) noodles mixed with soy sauce.

  • Recently the globalization of agriculture by the WTO has brought crisis to Korean farmers. Value added agricultural products is the one of the strategies to sustain fanning. The idea for the project traditional fermented soy paste production and distribution was developed by the Gyeonggi-do Agricultural Research Institute. It was necessary to know the purchase condition and consumer needs for production distribution of the soy products. This study aims to investigate the consumers' need analysis of direct-deal soy products and the conditions of a purchase. A questionnaire was administered to 590 subjects living in Gyeonggi-do, Korea. The 107 subjects procured soy paste to buy with the reason of ignorance of preparation (39.2%) and the difficulty of storage and care (31.8%). When selecting the product 95.3%, previous experience (41.1 %) and comparison of each product (34.6%) were major answers, wanted direct-deal purchase from producers if implemented. 142 subjects(24%) experienced direct deal with producers. The main direct route was government and public offices( 42.4 %). The reason for direct purchase was confidence of agricultural products(77.5%). Delivery of 4kg of soy paste and 1.8 L of soy sauce in a glass container (43.0%) was favored twice a year. The kind of soy products for consumers' needs was Doenjang(57.8%) and Gochujang(18.3%). The preferred methods direct-dealing of soy products was direct order(59.9%) after validation, delivery gate to gate (44.2%) and by the internet(4.9%). The results of the study shows that the types of production would have the kinds and quantities diversity with confidence, sanitation, and safety. To regain successful, traditional tastes it is necessary to develop reliable and tasteful products for consumers and develop promotional material.

  • 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.

  • This study categorized and made considerations of the fermented soybean pastes into Meju, Chungjang, Si, mixed Jang, and other Jang in accordance with the manufacturing methods described in the fermented soybean paste section of Sangayorok (1450's), Suunjapbang (1540's) and Gyemiseo (1554). These are ancient cook books written in Chinese characters during the first half of the Joseon Dynasty. The content on the fermented soybean pastes recorded in these books included 24 items in Sangayorok, 11 items in Suunjapbang, and 14 items in Gyemiseo. In conclusion, the most important fermented soybean pastes during the first half of the Joseon Dynasty were those used to produce soy sauce-like seasoning for the purpose of a-chieving a salty taste with Meju made of soybeans as the main ingredient. The manufacturing techniques for such traditional fermented soybean pastes have been passed down through history to the present era.

  • 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.
