The purpose of this paper is to estimate consumer's satisfaction by purchasing farmer's processed food. So, this paper surveyed consumers which have purchased Korean traditional soybean paste products, by reason of limiting research objects among lots of farmer's processed food. A survey of 220 consumers was carried out on September and October 2016. For this matters, this paper used multiple linear regression model(included LOG-LIN model) and, set up 1 dependent and 11 independent variables. As the analysis results, we could find out that consumer's satisfaction was affected by 6 variables(price, taste, ease of cooking, confidence of product information, social awareness and perceived 6th industrialization). Among these variables, the strongest variable was "social awareness", and the second was "perceived 6th industrialization". This paper also estimated the rate of change that a dependent variable was affected by independent variables. As the results, this paper found out that "perceived 6th industrialization" had the highest rate of change(5.8%) and the second was "social awareness"(5.6%). This paper proposed 7 implications of Korean traditional soybean paste. Those were the proper price policy and quality value's promotion, quality Improvement and confidence enhancement, development of products for consumer's convenience, enhancement of social awareness, enhancement of politic management about 6th industrialization and accessibility of purchasing information.

This study conducted surveys on perception and utilization of Korean soybean paste targeting 493 women from their 20s to 60s residing in Daegu. Most subjects married (75.3%), were part of a nuclear family (84.8%), had more than a high school diploma (95.8%), had a career (47.9%), lived in an apartment (68.4%), had a total household income of 5 million won or more (38.1%), and had monthly food expenses more than 0.5 million won and less than 1 million won (42.2%). Regarding perception, 'rich nutrition' was the most commonly held perception in subjects in their 60s (4.4), followed by 'good taste' in subjects in their 40s (4.3). Regarding reasons for consumption 'healthy' was highest in subjects in their 60s (47.3%) and 40s (45.6%) and 'delicious' in subjects in their 20s (56.1%). Regarding how to make it, subjects in their 60s responded 'know for sure' (57.1%), while only 2% of 20s responded the same. Subjects in their 50s and 60s had a higher ratio of answering 'know' while 20s and 30s 'don't know', For preparation methods, subjects in their 20s (53.1%) and 30s (41.4%) answered 'buy at the market', subjects in their 40s (68.9%) 'get from family or relatives' and subjects in their 60s (47.3%) 'make by one's own'. For preservation method, subjects in their 20s and 30s answered 'preserve in refrigerator', the 60s tend to answer 'preserve in jangdokdae'. Buying at the market was most common in subjects in their 20s (36.1%) and 30s (28.5%) and the reason was 'convenient' (39.6%). The place of purchase was 'in large supermarket or department store' (78.5%). For the future consumption pattern, 'increase in consumption of commercialized product (44.0%)', subjects in their 60s answered 'keep making at home' while subjects in their 30s and 40s answered 'keep making at home or buying product half and half'. According to the above study results, women living in Daegu region were aware of excellence of traditional soybean paste. However, due to changes in residential circumstance and lack of knowledge about the recipe, they did not make. They receive soybean paste t from family, relatives or bought in the market, which indicates the continuous decrease in home-made soybean paste. Therefore, due to the expanding social participation of women, the product market is expected to increase. I think it is important to develop traditional commercial soybean paste in the traditional way to improve the traditional flavors.

Gastric cancer was inducedd by N-nethyl-N'-nitro-N-nitrosoguanidine(MNNG) in Fisher 344 male rats. Freeze dried typical Koran feeds, aged kimchi, soybean paste and maejoo, and partially scorched barbecued bulgokee were fed to the rat in the diet, which were composing 10% of the total diet. Experimental desing was as follows ; (1) group C : Control, (2) group M : MNNG with control diet, (3) group MK : MNNG with 10% of kimchi, (4) group MS : MNNG with 10% of soybean paste and maejoo, (5) group MB : MNNG with 10% of barbecued bulagokee, (6) group MKSB ; MNNG with 10% of the mixture of kimchi, soybean paste and maejoo, and barbecued bulgokee. Each group was fed with isocaloric diet for 26 weeks. Comparing to control, the growth rate of the experimental group was decreased after administration of MNNG and experimental diet. The mortality rate of group MB was increased by 17% than the control group along with a significant decrease of body weight. The protein efficiency ratio and the food efficiency ratio of group MB were lower than the control. The incidence of gastric cancer in rats fed kimchi and barbecued bulgokee were 73% and 75%, respectively, while that of group M which fed MNNG remained only 56%. On the contrary, soybean paste and maejoo showed an inhibitory effect on the burden of gastric tumor. However, the combination of kimchi, soybean paste and maejoo, and barbecued bulogokee showed a synergistic effect of increasing tumorigenesis in rats. Pathological observations of the rat stomach represent that squamous cell type tumors occupied in most frequencies.

Previously, it has been reported that Aspergillus oryzae can efficiently degrade unpleasant odor components such as butyric acid and 3-methyl butanoic acid from meju, a major ingredient in both Korean soybean paste (doenjang) and soy sauce. In this study, the optimal manufacturing conditions for the production of superior quality Korean soybean paste and soy sauce were determined. Specifically, A. oryzae AJ 100 was utilized to improve the flavor of these products. Mixtures of Korean soybean paste and A. oryzae AJ 100 culture (2 : 1), and of Korean soy sauce and A. oryzae AJ 100 culture (5 : 1), were incubated for 2 weeks at $30^{\circ}C$, and showed improved flavor. Butyric acid and 3-methyl butanoic acid were clearly degraded under these culture conditions.

Fernbraken is a popular and well-known wild grass, but the physiochemical properties of Korean Traditional pickling (Jangachi) during aging have been little reported. Therefore, this study was carried out to investigate the physiochemical properties of Fernbraken Jangachi treated with a soybean sauce mixture for 6 weeks (1st pretreatment) as well as fermented with soybean paste, red hot pepper paste and soybean sauce for 7 weeks. Total polyphenol contents, acidity, salinity, sweetness (Brix), and ${\alpha}$-tocopherol of Fernbraken Jangachi all increased with aging period. On the other hand, pH and total acidity of Fernbraken Jangachi did not change much. Among the three kinds of Jangachies, Jangachi fermented with soybean sauce showed 2 fold higher salinity and total acidity levels compared to the others. Therefore, the physiochemical properties of Fernbraken Jangachi were dependent on the pickling properties, such as soybean paste, hot pepper paste or soybean sauce, and these properties maintained a certain level after 5~6 weeks of aging. Further, proper aging period for Fernbraken Jangachi was suggested as 10 weeks.

Jeupjang like salted soybean paste with vegetable is the Korean traditional side order eating at table. Bibliographical studies on the Jeupjang in historic books such as Jeungbo-Sanlim-Keongjae(Re-edition of agriculture economic), Imwon- Keongjae Ji(Book of country economic) and Keuhap-Chongseo(Handbook of household) described the Korean food in the 18 century carried out. In addition, investigation and analytical studies on various home-made Jeupjang in present was accomplished. Jeupjangs were classified into three types according to variety preparing methods. Three types were fermented soybean paste (Doenjang) type using traditional Meju(soybean cake stater) for Jeupjang, salted pickle (Jangachi) type buried cucumber and eggplant into soybean paste or soysauce (Kanjang), and salted sauer kraut (Kimchii) type prepared vegetable in Jeupjang-Meju mash. The procedures for producing Jeupjang were Jeupjang-Meju making, and mixing vegetable with Meju powder into brine. At last process was fermented in horse wastes or grasses for 7-14 days. But manufacturing methods of Jeupjang before the 18 century were different in present. Nowadays glutinous rice, red pepper powder and various vegetable were used for domestic Jeupjang.

In this study, the soy food intake behaviors including perception and intake frequency of soybean foods by sociodemographic variables were analyzed in housewives. The perception of housewives for soy foods showed that soybean paste, soybean curd, and Dambuk were high in the descending order for nutritional quality and health promotion effect, and soybean paste received the highest score in taste and flavor. Soybean sprouts received the highest evaluation score in the economic aspect. In the aspect of safe food, soybean paste received the highest evaluation score, as mush as a traditional food. The analysis of perception by sociodemographic variables showed that soybean curd, Dambuk, and soybean sprouts had higher perceptions as education level increased, and soy milk had higher perceptions in subjects with younger age and with employment. In the intake frequency, more than 50% of the subjects had soybean curd, soybean sprouts, and soybean paste more than once a week. The analysis for correlation between the intake frequency of soy foods and the degree of perception showed that taste and flavor had high correlation with the intake frequency of soy foods except soybean sprouts. The intake frequency of soybean paste, Dambuk, and soy milk had positive correlations to familiarity and that of soy milk had positive correlations to nutrition and health perception, and those of soybeam paste, soybean sprouts, and soy milk had positive correlations to safe food perception. From the above results, housewives in Korea had very high perceptions to nutritional quality and health promotion effect of soy foods and the degree of perception and accompanied intake frequency had significant differences by age, education level, and economic level among sociodemographic variables.
