In order to establish the quality standard of commercial soybean paste, pH, color, moisture, crude protein, isoflavone, free amino acid and organic acid contents of the fermented soybean food in both traditional and commercial products were analyzed. The crude protein contents were from 5.0 to 11.9% in commercial soybean pasted of Samjang and traditional soybean paste of Chungugjang, and the latter showed higher value than those of the former. The contents of isoflavones in commercial soybean paste were less than those of traditional soybean paste. Total contents of free amino acids were distributed from 301 to 4,602mg%, respectively, in which Chungugjang showed the smallest value of 301mg% and the traditional soybean paste showed the most abundant one of 4,602mg%. The ratio of glutamic acid to total free amino acids were 15.9% and 30.1% in traditional soybean paste and commercial soybean paste, respectively. The major organic acid both commercial soybean paste and Samjang was citric acid containing 109.9~196.5mg%. On the other hand, that of traditional soybean paste and Chungugjang was oxalic acid containing 82.8~130.1mg%. This results might be caused by the differences of brewed periods, microflora, processing methods and used raw materials.

To identify antimicrobial activities of soybean paste, studies have been carried out with laboratory manufactured soybean paste, traditional and improved type soybean paste purchased on the market. The soybean paste fermented with Aspergillus oryzae and Rhizopus tamari and commercial soybean paste were shown antimicrobial activities for Bacillus cereus, Escherichia coli, Listeria monocytogenes, Staphy lococcus aureus, Streptococcus faecalis, Escherichia coli O157:H7, Bacillus subtilis and Salmonella typhimurium. Non fermented soybean paste did not show antimicrobial activities against Bacillus cereus, Escherichia coli, Listeria monocytogenes, Staphylococcus aureus and Streptococcus faecalis. The extract of soybean paste extracted by 80% methanol showed the highest antimicrobial activities of in ethyl acetate fraction and followed butanol fraction, respectively. Antimicrobial activities of traditional and improved type soybean paste were shown against all tested microorganisms and clear zone length of traditional soybean paste was slightly larger than that of improved type. Components of antimicrobial fractions of soybean paste were guessed peptides, 4 hydroxy benzoic acid, benzoic acid by GC MS.

This study is proceeded on the development of standard method for making soybean paste by Korean traditional method. Fermentation condition of Meju was 1) Pre-fermentation : 30 days in about 20$^{\circ}C$ room, 2) Main fermentation : 5 days in 30$^{\circ}C$ or upper temperature, 3) Post fermentation and drying : 30 days in well sunlightened room in January. Meju was soaked in 18% salt solution(Meju 7kg/salt solution 20L) for 35～40 days (from late February to early April) and after soaking Meju was filtered as unsoluble solute and crushed and put into traditional Korean receptacle(named 'Dok'). Crushed Meju was stored from early April to mid September and Meju was changed into soybean paste(Doen-jang). During fermentation amino acid nitrogen in Doen-jang was slightly increased in early period and decreased lately. It has been proved that by panel test soybean paste made by the method suggested in this study was more excellent than commercially fermented soybean paste. This study has presented the possibility of commercial production of soybean paste made by traditional method.

Traditional soybean paste from Shandong Liangshan and Tianyuan Jiangyuan commercial soybean paste were chosen for analysis and comparison of their bacterial and fungal dynamics using denaturing gel gradient electrophoresis and 16S rRNA gene clone libraries. The bacterial diversity results showed that more than 20 types of bacteria were present in traditional Shandong soybean paste during its fermentation process, whereas only six types of bacteria were present in the commercial soybean paste. The predominant bacteria in the Shandong soybean paste were most closely related to Leuconostoc spp., an uncultured bacterium, Lactococcus lactis, Bacillus licheniformis, Bacillus spp., and Citrobacter freundii. The predominant bacteria in the Tianyuan Jiangyuan soybean paste were most closely related to an uncultured bacterium, Bacillus licheniformis, and an uncultured Leuconostoc spp. The fungal diversity results showed that 10 types of fungi were present in the Shandong soybean paste during the fermentation process, with the predominant fungi being most closely related to Geotrichum spp., an uncultured fungal clone, Aspergillus oryzae, and yeast species. The predominant fungus in the commercial soybean paste was Aspergillus oryzae.

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.

Purpose: This study aimed to investigate the quality characteristics of traditional and commercial soybean pastes (Doenjang) for development of traditional soybean pastes. Methods: Proximate compositions, amino acid nitrogen contents, pH, acidity, salt contents, chromaticity, viable bacteria and inorganic substance contents of nineteen traditional and three commercial Doenjang were investigated. Results: Analysis of proximate compositions indicated a significant difference between samples. In moisture content, D10 did not meet the standard of food codex. The contents of moisture, fat, protein and ash were slightly higher in traditional than commercial Doenjang. However, the carbohydrate content was 2-fold higher in commercial than traditional, and thus, the calories were also higher. The amino nitrogen content was lower in commercial than traditional Doenjang. pH, acidity and salt contents of Doenjang were pH 4.67-6.15, 1.53-3.29%, and 9.01-18.78%, respectively. pH and acidity showed no significant differences between traditional and commercial Doenjang, however, salt contents were significantly higher in traditional than commercial Doenjang. In case of chromaticity, the averages of L, a, b values were higher in traditional Doenjang. In microbiological analysis, total bacteria counts were higher in traditional than commercial Doenjang. The number of Bacillus cereus in D12 and D19 exceeded the standard of food codex. Staphylococcus aureust was undetected in all samples. The number of fungi varied widely between samples, with no detection in five traditional and all commercial Doenjang. Results of inorganic substance analysis indicated that contents of inorganic substances in Doenjang were in order of Na, K, Mg and Ca. Overall, Na content was higher in traditional Doenjang. Contents of inorganic substances showed wide variations in traditional Doenjang. Conclusion: For the development of traditional Doenjang, quality standardization and ensuring safety are considered necessary.
