  • This study was conducted to find out the successive habitual practice of dietary life and all the educational tasks for the purpose of activating with female college students in Korea and Japan. The reesults are as follows. Housewives in both countries prepare ${\ulcorner}the\;same\;menu{\lrcorner}$ for dinner about 65%. ${\ulcorner}The\;rate\;of\;domestic\;manufacturing\;of\;preservated\;food\;{\lrcorner}$ is superior in Korea. ${\ulcorner}Goch'ujang{\lrcorner}$ is made by the 92% of Koreans, ${\ulcorner}Doenjang{\lrcorner}\;89%,\;{\ulcorner}Ganjang{\lrcorner}\;48%,\;{\ulcorner}Oiji{\lrcorner}\;44%\;and\;{\ulcorner}Kimchi{\lrcorner}\;40%.\;{\ulcorner}Umeboshi{\lrcorner}$ is made by the 65% of Japanese, ${\ulcorner}Rakkyo-Zuke{\lrcorner}\;37%,\;{\ulcorner}Kajitsu-syu{\lrcorner}\;40%,\;and\;{\ulcorner}Miso{\lrcorner}$ 27%. Two countries' common seasonings are ${\ulcorner}Ganjang{\lrcorner},\;{\ulcorner}Salt{\lrcorner},\;{\ulcorner}Chemical\;condiment{\lrcorner},\;{\ulcorner}Sugar{\lrcorner},\;{\ulcorner}Pepper{\lrcorner},\;{\ulcorner}Doenjang${\lrcorner}\;and\;{\ulcorner}Vinegar{\lrcorner}$. Koreans use the traditional seasonings, and in addition flavoring vegetables and oil which is Korea's own characteristic. Japanese use western seasonings frequently besides traditional seasonings. ${\ulcorner}Mother's\;representative\;food{\lrcorner}$ as home dish are conscentrated on each count's native food. ${\ulcorner}Kimch'i\;lyu{\lrcorner}$ is made by the 42% of Koreans, ${\ulcorner}Doenjangchigae{\lrcorner}\;39%,\;{\ulcorner}Dakgangjong{\lrcorner}\;31%,\;and\;{\ulcorner}Saongsonmaeuntang{\lrcorner}\;19%.\;{\ulcorner}Misoshiru{\lrcorner}$ is made by the 83% of Japanese, ${\ulcorner}Nishime{\lrcorner}\;76%\;and\;{\ulcorner}Nikujaga{\lrcorner}$ 38%. Korea has more diverse kinds of food. People eat out ${\ulcorner}when\;they\;have\;special\;home \;events{\lrcorner},\;{\ulcorner}when\;they\;would\;like\;to\;do{\lrcorner},\;and\;{\ulcorner}when\;they\;are\;going\;out{\lrcorner}$, It means that to eat out is one of the daily dinning styles. Therefore, for those who are engaged in eating house business it is necessary to form their righteous view of evaluation. Koreans learn more various items of table manner than Japan, which are the symbols of dietary culture. ${\ulcorner}Carriage{\lrcorner}\;and\;{\ulcorner}Eating\;politely{\lrcorner}$ are common items. The extent to which ${\ulcorner}people\;practice\;table\;manner{\lrcorner}$ and to which ${\ulcorner}people\;think\;of\;it\;as\;being\;worth\;practicing{\lrcorner}$ are high in Japan than Korea.

  • To investigate the effect of the predominant fungal species from Korean traditional meju and doenjang on soybean fermentation, the enzymatic activity and amino acid production of twenty-two fungal strains were assessed through solid- and liquid-state soybean fermentation. Enzymatic activity analyses of solid-state fermented soybeans revealed different enzyme activities involving protease, leucine aminopeptidase (LAP), carboxypeptidase (CaP), glutaminase, γ-glutamyl transferase (GGT), and amylase, depending on the fungal species. These enzymatic activities significantly affected the amino acid profile throughout liquid-state fermentation. Strains belonging to Mucoromycota, including Lichtheimia, Mucor, Rhizomucor, and Rhizopus, produced smaller amounts of total amino acids and umami-producing amino acids, such as glutamic acid and aspartic acid, than strains belonging to Aspergillus subgenus circumdati. The genera Penicillium and Scopulariopsis produced large amounts of total amino acids and glutamic acid, suggesting that these genera play an essential role in producing umami and kokumi tastes in fermented soybean products. Strains belonging to Aspergillus subgenus circumdati, including A. oryzae, showed the highest amino acid content, including glutamic acid, suggesting the potential benefits of A. oryzae as a starter for soybean fermentation. This study showed the potential of traditional meju strains as starters for soybean fermentation. However, further analysis of processes such as the production of G-peptide for kokumi taste and volatile compounds for flavor and safety is needed.

  • Aspergillus flavus를 포함한 수종의 곰팡이들은 사람과 가축에 독성이 있는 저분자의 2차대사산물을 생산하며 이를 mycotoxin이라고 부른다. 우리나라 여름과 같은 적당한 온도와 습도는 유해곰팡이의 성장이 가능하여 쌀, 보리, 옥수수, 메주, 된장, 간장 및 고추장과 같은 전통식품 및 그 재료와 같은 대부분의 유기물질에서 mycotoxin이 생산될 수 있다. 지금까지 여러 사람들은 Aspergillus속, Penicillium속, Fusarium속 곰팡이를 전통식품과 그 재료로부터 분리하였으며, 그 중에서 여러 mycotoxin을 생산하는 곰팡이를 검색하였다. 또한 상기와 비슷한 시료에서 aflatoxin, ochratoxin, deoxynivalenol(DON) 및 zearalenone 등의 mycotoxin오염을 확인하기도 했다. 그러나 이러한 자료들은 실험조건과 방법에서 서로 상이하며 일관성이 결여되어있고, 특히 대부분의 실험들이 일과성으로 끝났기 때문에 곰팡이독소를 중심으로 하여 전통식품을 객관적으로 평가하기 위해서는 보다 지속적이고 합리적인 실험방법과 재료가 요구된다. 이러한 목적을 위해서는 새로운 첨단기술을 응용하여 mycotoxin을 보다 간편하고 신속히 분석할 수 있는 방법을 개발해야하며, 또한 보다 지속적인 연구비 투자와 연구시설의 확충으로 연구의 활성화와 기술축적을 위한 노력을 해야할 것이다. 이 같은 합리적인 노력으로 전통식품의 mycotoxin 오염여부를 지속적으로 조사하고, 아울러 우리 전통식품의 안전성을 확보하는 것이 가능하며 그 결과 국제화 시대에 부응하는 보다나은 전통식품의 보존과 개발이 이루어지게 될 것이다.

  • 본 논문은 분말된장의 첨가가 닭고기 소시지의 품질 및 저장성에 미치는 영향을 구명하기 위하여 분말된장을 첨가하지 않은 대조구(C)와 분말된장 2% 첨가구(DP2), 분말된장 5% 첨가구(DP5), 분말된장 8% 첨가구(DP8)로 나누어 일주일 간격으로 총 4주간 실험을 실시하였다. 실험 결과, pH에서는 분말된장 처리구가 분말된장을 첨가하지 않은 대조구(C)에 비해 유의적으로 낮은 값을 보였다(p<0.05). TBARS에서는 분말된장 첨가구가 대조구(C)에 비해 지방산패를 억제함을 알 수 있었으며(p<0.05), 분말된장 5% 처리구(DP5)가 저장 4주차에 다른 처리구들에 비해 유의적으로 낮은 TBARS 값을 나타내었다(p<0.05). 단백질 변패를 나타내는 VBN은 분말된장 8% 처리구(DP8)가 다른 처리구들에 비해 유의적으로 높은 값이 나왔다(p<0.05). 닭고기 소시지의 보수력은 된장분말 첨가에 의한 영향을 받지 않았다(p<0.05). 표면육색 측정 결과, 명도 값은 분말된장 첨가구가 대조구에 비해 유의적으로 낮았으며(p<0.05), 적색도 및 황색도에서는 분말된장 5% 처리구(DP5)가 다른 처리구들에 비해 유의적으로 높은 값을 보였다(p<0.05). 조직감 측정 결과, 경도, 탄력성, 점성, 씹힘성 항목에서 분말된장 5% 처리구(DP5)와 분말된장 8% 처리구(DP8)가 다른 처리구들에 비해 유의적으로 낮은 값을 보였다(p<0.05). 닭고기 소시지의 저장 중 총 호기성 및 혐기성균은 분말된장 5 및 8% 첨가에 의해 증식이 억제되는 것이 확인되었다. 이상의 결과를 종합해 볼 때 닭고기 소시지 제조 시 분말된장의 첨가는 무첨가구에 비해 저장성이 우수한 소시지를 만들 수 있을 것으로 예상되며, 한국 전통양념을 이용한 육가공 식품이 전무한 시점에서 이화학적으로 새로운 맛의 제품을 만들어 소비자들의 이목을 끌 수 있을 것으로 사료된다.

  • Bacillus cereus is a gram-positive, rod-shaped, spore-forming bacterium that has been isolated from contaminated fermented soybean food products and from the environment. B. cereus produces diarrheal and emetic toxins and has caused many outbreaks of foodborne diseases. In this study, we investigated whether B. amyloliquefaciens RD7-7, isolated from rice doenjang (Korean fermented soybean paste), a traditional Korean fermented soybean food, shows antimicrobial activity against B. cereus and regulates its toxin gene expression. B. amyloliquefaciens RD7-7 exhibited strong antibacterial activity against B. cereus and inhibited the expression of B. cereus toxin-related genes (groEL, nheA, nheC, and entFM). We also found that addition of water extracts of soybean and buckwheat soksungjang (Korean fermented soybean paste made in a short time) fermented with B. amyloliquefaciens RD7-7 significantly reduced the growth and toxin expression of B. cereus. These results indicate that B. amyloliquefaciens RD7-7 could be used to control B. cereus growth and toxin production in the fermented soybean food industry. Our findings also provide a basis for the development of candidate biological control agents against B. cereus to improve the safety of fermented soybean food products.

  • Ganjang and doenjang are known as major fermented soy-based foods in Koreans. Current investigations have proved that fermented soybean foods impart anti-cancer, anti-obesity, and anti-diabetic effects. The aim of this study was to evaluate the anti-cancer activities of commercialized soy food, Ganjang, as a function of aging period. The test groups were classified into four time periods-short (under 5 years, S group), mid (under 10 years, M group), long (under 15 years, L group), and eternal (over 15 years, E group). The anti-cancer effects of Ganjang were determined by cell cytotoxicity assay of three types of cancer cell lines and splenocyte proliferation assay. Besides these assays, we also analyzed NK cell activity for cancer immunotherapy. The results show that the anti-cancer effect increased in the S and M period aging groups for all three cancer cell lines. Interestingly, similar to the anti-cancer result, splenocyte proliferation and NK activity showed the highest effect in the S and M groups. In contrast, Japanese ganjang-treated (JG1, JG2) groups and E group showed significantly reduced splenocyte proliferation. Collectively, these results suggest that the short and middle periods of traditional fermented Ganjang might have potential anti-cancer activities.

  • To facilitate establishing regulations for irradiated foods, Korean traditional soybean-based fermented powdered doenjang (PD), kanjang (PK), kochujang (PKC) and chungkukjang (PC) were irradiated at 1, 3, 5 and 7 kGy, and subjected to irradiation detection analyses as part of establishing a database for detecting irradiated foods. Photostimulated luminescence (PSL) and electron spin resonance (ESR) were applied as the detection methods. Using PSL analysis, the irradiated PD, PK and PKC could be easily distinguished from the non-irradiated ones, while irradiation of the PC at 5 kGy or higher was detectable. The ESR spectra of the irradiated PD, PK and PKC exhibited symmetrical multiplet lines, which might be induced from the crystalline sugar, whereas, the PC showed a single signal at the paramagnetic centers. The signal intensity increased with incremental increases of irradiation doses distinguishing the irradiated samples from the control. In addition, the peak height also revealed that irradiation induced an increment in the intensity of single and/or multiplet lines of the ESR signals, resulting in clear confirmation of irradiation. Thus, the data from this study could be used as references for detecting irradiated soybean-based fermented powdered sauces.

  • 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.
