This study evaluates the quality properties of soy-paste soybean cultivar for fermented soybean products. The six soybean varieties that include Jinpung, Saedanbaek, Daepung 2, Pyeongwon, Cheonga and Saeolkong were used in the experiment. The range of water uptake ratio, hardness after soaking and hardness after steaming were 117.00~131.33%, 1.65~3.30 kg and 0.05~0.14 kg, respectively. The physicochemical analysis indicated the following: Moisture content, 63.27~68.72%; pH, 6.43~6.60; total acidity, 0.27~0.45%. Color values for L value (lightness), a value (redness), and b value (yellowness) ranged from 39.07~67.92, 7.64~11.79, and 7.48~20.67, respectively. The amylase and protease activities of the Saedanbaek samples were the highest among all cultivars. The amount of viscous substance in the fermented soybean products by cultivars ranged from 5.93 to 8.37%, and Saedanbaek was the highest. The total viable cells counts for soybean fermented products were 9.11~9.42 log CFU/g. The amino-type nitrogen contents of all samples were in the range of 401.07 to 524.47 mg% and Saedanbaek cultivars showed the highest content (524.47 mg%). Based on the results, Saedanbaek will be suitable as a soy-paste soybean cultivar and the quality standards for the fermentation process of the fermented soybean products.

The consumption of high-salt foods is an independent risk factor for increased hypertension. Thus, evaluating the relationship of taste sensitivity and pleasantness of high-salt foods such as Korean jang products, would help contribute to an understanding of salty food eating behaviors of the Korean rural elderly. This study aimed to verify the association between taste sensitivity and salinity of Korean jang products, and the preferences of food groups and nutrient intake in the rural elderly. We studied 269 elderly persons (males 83, females 186) aged above 65 years, residing in the rural area, Sunchang gun Jeonbuk. For each subject, a recognition threshold of 4 basic tastes and pleasant concentrations of NaCl were estimated using the sip- and–spit method. Taste preferences, frequency of intake of food groups, nutrient intakes, and salinity and sweetness of Korean jang products (Doenjang, Ganjang, Gochujang) were assessed. No association was found between salt taste recognition threshold and optimally preferred concentration of salt and salinity of Korean jang products. However, the sweet taste recognition threshold was positively related to the sweetness of Korean jang products. Also, the salinity of Doenjang positively correlated with the frequencies of food groups and nutrient intakes. That is to say that the sweet taste sensitivity was related to the sweetness of Korean jang products, but was not sensitive to the salty taste. The salinity of Doenjang correlated with the consumption of food and nutrient intakes. Taken together, these findings suggest the need for appropriate intervention and education to reduce the salinity of Doenjang, which is an important modifiable factor contributing to reducing sodium intake in the rural elderly.

This study aimed to investigate potential acceptability of Korean jang products among Halal food consumer’s to predict its market possibility in a Halal food market. Focus Group Interview (FGI) was implemented to 11 Halal food consumers residing in Korea for more than 4 month. During the test, 3 types of fermented paste, doenjang, ssamjang and gochujang were evaluated by applying these to Korean foods. In depth interview was conducted on the liking of the jang applied samples, general experiences of Korean food and fermented food in their home countries. The results showed that consumers were positive to Korean jang applied samples in general. The mean liking ratings of doenjang, ssamjang and gochujang were 7.1, 7 and 7.6 on 9-point hedonic scale, respectively. Consumers focused on the sweet and spicy flavor quality of the samples. Consumers commonly responded that the doenjang tasted too salty and needed to increase sweet and spicy flavor, and ssamjang needed to increase spicy flavor as well. Sweetening was necessary for gochujang. The reasons of liking Korean jang were because the flavors were unique yet familiar. The balanced flavor of salty, sweet and spicy flavor were additional reasons of liking. However, the fermented smell of jang products were reasons of disliking the products.

The sauce and paste, which is collectively called as ‘jang’ in Korean is the staple seasoning of Korean cuisine. Although China shares some aspects of the Jang (醬), the exact types and forms are different. In this study, we explore the current Korean jang through the six culinary books-「Seongwonlog (醒園錄)」,「Yangsolog (養小錄)」,「Jojeongjip (調鼎集),「Susiggeeumsigbo (隨息居飮食譜)」,「Junggwerok (中饋錄)」, and「Sosigseolyag (素食說略)」 from the Qing Dynasty of China. The Jang of Qing Dynasty are further classified into the Chumjang (甛醬), Dusi (豆鼓), Chungjang (淸醬), and jangyou (醬油). To make these four types, the huangzi (黃子) has to be first made from the flour or beans, after which salt is added and sun-dried. Chumjang is the type of Chunjang used to make Zhajiangmian and is widely used in the Northern part of China. Like Chumjang, Dusi is made from flour and beans. Salt as well as various spices like Star anise, Chinese pepper and sesame are added. This type of paste is widely used in the Southern part of China. Chungjang is made when salt and water are added and sun-dried, after which it is filtered through an apparatus called Jangyou. The final product is sauce similar to today’s soybean sauce.

On the basis of the cookbooks and Data Base of the Korean Classics(http://db.itkc.or.kr/itkcdb/mainIndexIframe.jsp), this paper analyzed the fermented soybean listed in the general documents of the Chosun Dynasty(1392～1897) and the Goryeo Dynasty(918～1392). In the Goryeo Dynasty, there are 15 kinds of Jang(soybean paste or solution), among which are Jang (soybean paste fermented by mold)(6 documents), Yeomgjang, Yeomshi(2), and Gaejang(1). However, the cookbook at that time is defunct. The Goryeo Court relieved the famine-stricken people by proving them with Jang. In the Chosun Dynasty, 111 kinds of Jang were listed in the general documents, and 153 kinds in cookbooks. There were 55 kinds of general Jang, such as Jang(204), Yeomjang(63), Chojang, Goojang(7), and Gaejang(6), are listed in the general documents, and in the cookbooks, there are 55 kinds of Jang, such as Sookwhangjang(9 cookbooks), Daemaekjang(8), Myeonjang(8), Saengwhangjang (8), and Yooinjang(8), and among them, 13 kinds belong to the Chinese origin. A total of 9 Kinds of Ganjang(soybean solution fermented by mold), such as Soojang(30), Cheongjang(23), Gamjang(8), and Ganjang(3) are found in the general documents. In the cookbooks, 12 kinds of Jang, as Cheongjang(10), Cheonrijang(4), Ganjang(3), and etc., are listed. There were 9 kinds of Gochoojang(red pepper-soybean paste), such as Chojang(12), Gochojang(3), and etc., are listed in the general documents, and 9 kinds as Gochojang(7), Manchojang(7), rapid Manchojang(4), and etc., are in the cookbooks. In addition, 16 Kinds of Yookjang(fermented soybean-meat paste) as Haejang(15), Hyejang(11), Yookjang(11), and etc., are found in the documents, and 22 kinds as Nanjang(9), Gejang(6), Yookjang(5), Shoigogijang(4), and etc., are in the cookbooks. Eighteen Kinds of Shi(soybean paste fermented by bacteria) as Yeomshi(40), Shi(35), Shijang(6), and etc., are recorded in the documents, and 19 kinds as Jeonkookjang(6), Shi(4), Sooshijang(4), and etc., are in the cookbooks, and among them 11 kinds belong to the Chinese origin. Six kinds of Jipjang(aqueous soybean paste) as Jipjang(7), Uoopjang(4), Pojang (2), Jangzoop(2) are recorded in the documents, and 15 kinds as Jipjang(9), Zoopjeo(7), and Hajeoljipjang(5) are in the cookbooks. Soybean paste, or solution for relieving hunger is not recorded in the documents. However, the Chosun court, for the purpose of relieving famine-stricken people, used general Jang. Such 21 Jang to relieve the famine-stricken people as Pojang(7), rapid Jang(6), and Sasamgilgyeongjang(4) are listed in the cookbook. Geonjang(dried soybean paste), Nanjang (egg-soybean paste), Doojang(soybean paste), Maljang(random soybean paste), Myeonjang(wheate-soybean paste), Sodoojang (red bean-soybean paste), Yookjang(soybean-meat paste) and Jang(soybean paste) are recorded in the documents, as well as in the cookbooks. Chinese-original Jang and Shi are recorded in the cookbooks, with no list in the general documents. Therefore, it seems that it didn't pass down to the general public.

This paper investigated the system that is relevant to Jang(fermented soybean paste or solution), the relief of hunger- stricken people by Jang, 33 kinds of Jang, and its consumption in the documents, such as the annals of the Chosun Dynasty, Ihlseong-document, Seungjeongwon daily, Uigwe(record of national ceremony), official documents on the basis of Kyujanggak institute for the Korean studies and data base of Korean classics. There are lots of Jang named after the place of particular soybean's production from the ancient times. Jang, soybean, salt and Meju(source of Jang), during the Dynasty, were collected as taxation or tribute. In the 5th year of Hyeonjong(1664), the storage amount of soybean in Hojo(ministry of finance) was 16, 200 ㎘, and its consumption was 7, 694 ㎘ a year. In the 32nd year of Yongjo(1756), the 1, 800 ㎘ of soybean was distributed to the people at the time of disaster, and in his 36th year(1756), the 15, 426 ㎘ of soybean was reduced from the soybean taxation nationwide. The offices managing Jang are Naejashi, Saseonseo, Sadoshi, Yebinshi and Bongsangshi. Chongyoongcheong(Gyeonggi military headquarters) stored the 175.14 ㎘ of Jang, and the 198 ㎘ of Jang in Yebinshi. There are such posts managing Jang as Jangsaek, Jangdoo, and Saseonsikjang. In the year of Jeongjong(1777～1800), the royal family distributed the 3.6 ㎘ of Meju to Gasoon-court, Hygyeong-court, queen's mother-court, queen's court, royal palace. The 13.41 ㎘ of Gamjang(fermented soybean solution) was distributed to the Gasoon-court, 17.23 ㎘ to Hegyeong-court, 17.09 ㎘ to the queen's mother-court, and the 17.17 ㎘ to the queen's court each. There are 112 Jang-storing pots in the royal storages, and the 690 are in Namhan-hill, where the 2.7 ㎘ of fermented Jang was made and brought back by them each year. At the time of starvation, Jang relieved the starving people. There are 20 occasions of big reliefs, according to the annals of the Chosun Dynasty. In the 5th year of Sejong(1423), the 360 ㎘ of Jang was given to the hunger-stricken people. In his 6th year(1424), the 8, 512.92 ㎘ of rice, bean, and Jang was provided and in the 28th year(1446), the 8, 322.68 ㎘ of Jang was also provided to them. In the Dynasty, Jang was given as a salary. In case that when they were bereaved, they didn't eat Jang patiently for its preservation. They were awarded for their filial piety. In the annals of the Chosun Dynasty, there are 19 kinds of Jang. They are listed in the order of Jang(108), Yeomjang(90), Maljang(11), Yookjang(5), Gamjang(4), and etc., . In Seungjeongwon daily, there are 11 kinds of Jang. Jang(6), Cheongjang (5), Maljang(5), and Tojang(3) are listed in order. In the Ihlseong-document, there are 5 kinds of Jang. They are listed in Jang(15), Maljang(2), Gamjang(2), and etc., . There are 13 kinds of Jang in Uigwe, and the official documents, in the order of Gamjang(59), Ganjang(37), Jang(28), Yeomjang(7), Maljang(6), and Cheongjang(5). In addition, shi are Jeonshi(7), and Dooshi(4). All these are made of only soybean except, for Yookjang. The most-frequently recorded Jang among anthology, cookbook, the annals of the Chosun Dynasty, Ihlseong-document, Seoungjeongwon daily, Uigwe, or officialdocument is Jang(372), and then Yeomjang(194), Gamjang(73), Cheongjang(46), Ganjang(46), Soojang(33), and Maljang(26), which were made of soybean. Jang from China in cookbook is not in anthology and royal palace documents. Thus, traditional Jang made of soybean was used in the daily food life in the royal court, and in the public during the Chosun period.

범주화는 제품디자인에 있어서 매우 중요하다. 범주화의 유형에 따라 소비자의 감성이 다르고 감성의 차이에 따라 디자인 컨셉이 다르며 이에 따라 디자인요소가 다르게 배합되어야 하기 때문이다. 특히 요즘처럼 제품라인이 확대되어 제품의 차별화가 모호한 경우에는 범주화과정이 필요하다. 즉 감성의 유사성 정도를 바탕으로 정확한 범주를 정하고 컨셉화하여 소비자 지향적인 디자인을 제공해야 하는 것이다. 본 연구는 특정의 제품범주(장류) 안에 유사한 하위범주(고추장, 된장, 청국장, 쌈장, 간장)를 구성하고 있는 각 제품에 대한 소비자의 감성이미지를 추출하고 그 유사성정도를 바탕으로 범주를 결정하여 디자인방향을 어떻게 결정해야 할지를 제시하는 데 목적이 있다. 본 연구를 통해 살펴본 결과, 장류는 선호하는 이미지로부터 차별화되어있지 않다는 것을 알 수 있다. 장류에 대한 감성 이미지 조사에서, "웰빙의", "감칠맛나는"의 감성 이미지는 선호에 긍정적인 영향을 미치는 반면, "지저분한", "냄새나는"의 감성 이미지는 선호에 부정적인 영향을 미치는 것으로 나타났다. 따라서 우리는 장류제품을 개발할 때 "감칠맛 나는"과 같은 긍정적인 감성이미지는 부각시키고, "지저분한" 이미지와 같은 부정적인 감성이미지를 제거할 수 있는 디자인 및 마케팅 전략을 제안한다. 본 연구는 학문적 측면과 실무적 측면에서 제품디자인에 대한 다양한 통찰력을 제공할 것이다.

Toxicological safety on 20 kGy-gamma irradiated Kanjang (soy sauce), Doenjang (soybean paste), Kochujang (hot pepper paste) and Chungkukjang (soy paste) was determined by SOS Chromotest. As the strain of the SOS Chromotest, Escherichia coli PQ37 was used in the condition of presence or absence of an exogenous metabolizing system (S-9 mix). Water extract or organic solvent extract was prepared from samples, concentrated and tested by SOS Chromotest with S-9 mix or not. All irradiated samples were not different from non-irradiated one in the bacterial assay maintaining the below 1.5 of IF(induction factor) values in the adapted dose of 10,000 ㎍/assay. The results indicated that any mutagenicity was not observed in 20 kGy-irradiated traditional soybean fermented foods.

Gamma irradiation at 20 kGy was applied to Kanjang (soy sauce), Doenjang (soybean paste), Kochujang (hot pepper paste) and Chungkukjang for their possible genotoxicity The genotoxicity of 20 kGy-irradiated samples was evaluated by Salmonella typhimurlum reversion assay. The Salmonella tester strains included TA98, TA100, TA1535 and TA1537 in the absence and presence of an exogenous metabolizing system (S9 mix). All samples were negative in the bacterial reversion assay with S. typhimurium TA98, TA100, TA1535 and TA1537. The results indicated that 20 kGy of gamma irradiation on water-soluble fraction of Kanjang, Doenjang, Kochujang and Chungkukjang were not shown mutagenicity.

부산, 양산, 울산 지역에 거주하는 주부 308명을 대상으로 장류에 대한 소비형태를 조사하였다. 된장의 경우 조사대상자의 67.2%가 일주일에 1∼2번 정도, 22.7%가 하루에 한 번 이상 식사준비에 이용하였다. 교육수준으로 볼 때 초등졸과 중졸 주부들의 이용빈도가 높았다. 된장의 마련방법은 46.9%가 집에서 담그며, 그 중 55.3%는 직접 만든 메주를 이용하고, 30.7%는 친척으로부터 가져온 된장을 먹고, 22.4%는 시판 제품을 구입하여 먹고 있었다. 집에서 담그거나 친척으로부터 가져다 먹는 가장 큰 이유는 맛 때문이었으며 시판 제품을 이용하는 이유는 편리하다는 것이 가장 컸다. 시판 된장의 이용은 울산지역에서, 연령은 낮거나 교육수준은 높을수록 이용율이 높았다. 고추장은 61.9%의 주부가 일주일에 1∼2번 정도, 25.4%가 하루에 한 번 이상 이용하였다. 집에서 담그는 경우는 51.1%, 시판 제품을 이용하는 경우는 22.3%로 소비 정도와 마련방법이 된장과 유사하였다. 청국장은 냄새 때문에 조사대상 주부의 60.3%가 거의 이용하지 않고 있었으며, 이용하는 경우에도 대부분이 시판 제품을 구입하면서 다른 장류보다 이용율이 크게 낮았다. 간장은 일주일에 1∼2번 정도 이용하는 경우가 가장 많았고, 국간장보다는 진간장을 더 많이 이용하는 것으로 나타났다. 마련방법으로는 국간장은 집에서 담그는 경우가 31.0%, 친척으로부터 가져다 먹는 경우가 29.5%, 시판 제품을 이용하는 경우가 38.1%로 나타났고, 주부의 연령이 낮을수록 교육수준이 높을수록 집에서 담그는 비율이 낮았다. 진간장은 65.0%가 시판 제품을 이용하고 있었다.
