  • Physico-chemical properties of ssamjang prepared by industrial process were investigated. Overall experiments were planned by central composite design for five independent variables, kochujang mash aging period $(X_{1})$, doenjang aging period $(X_{2})$, doenjang content $(X_{3})$, sterilization temperature $(X_{4})$, and storage temperature $(X_{5})$. Storage period had no consistent effect on moisture content of ssamjang. Doenjang having longer aging period showed lower moisture content than that having shorter aging period. Titratable acidity and pH of ssamjang gradually increased and decreased with storage period, respectively, with pH of ssamjang significantly affected by aging period of doenjang and kochujang mashes, and sterilization and storage temperatures. Amino nitrogen contents of ssamjang increased during storage and were more affected by sterilization temperature than by aging period and content of doenjang, and storage temperature. Crude protein content of ssamjang irregularly changed during storage, and was slightly affected by content of doenjang.

  • This study investigated the quality variation characteristics of Ssamjang containing Cheongkukjang, in order to improve the degree of preference of Cheongkukjang. The amount of Cheongkukjang was set at 1% based on sensory evaluation. Ssamjang containing Cheongkukjang was stored at $37^{\circ}C$ for 13 weeks, after which quality variation characteristics were weekly. During storage for 13 weeks, physicochemical quality characteristics, moisture content, and pH of Ssamjang containing Cheongkukjang slightly decreased, whereas salt content did not change. Amino nitrogen content slightly increased by 1 week but decreased by 3 weeks and then increased by 5 weeks. For microbiology quality characteristics, viable cell counts and total cell counts of B. cereus were unchanged. For sensory quality characteristics, shape quality was poor after 13 weeks while mold, drying phenomenon, and swelling phenomenon were not observed. Therefore, physicochemical quality and microbiology quality of Ssamjang containing Cheongkukjang were unchanged during storage for 13 weeks, and the storage limit was determined to be 12 weeks according to sensory quality evaluation.

  • The effect of additives on the quality of ssamjang was investigated during storage. The L-, a- and b-values of ssamjang decreased gradually during storage, and the total color difference (${\Delta}E$) increased in the control group. The gas production of ssamjang was reduced in K-sorbate, alcohol and mustard added groups. The number of yeast increased rapidly up to 6 weeks of storage, then decreased in the mustard, alcohol, and K-sorbate added groups. The oxidation-reduction potential and water activity decreased until 6 weeks and 12 weeks, respectively, and then increased gradually. Titratable acidity increased with concomitant decrease in pH, however, it increased slightly in the K-sorbate and ethanol added groups. Reducing sugar content increased until 9 weeks of storage, except the turmeric added group. Alcohol content increased until 15 weeks in the Japanese apricot juice, and turmeric added group. The sensory test result for the taste, flavor and overall acceptability showed that mustard added ssamjang was more acceptable than other groups.

  • Purpose: This study was conducted to develop easy-made ssamjang products with differentiated materials and methods to meet the needs for a healthy and easy- lifestyle trend with lowered manufacturing expenses. Methods: Ssamjang was made with cheonggukjang and different kinds of jocheong as glutinous (GRSS), sweet potato (SPTSS), sweet pumpkin (SPKSS), bellflower root (BRSS) and ginger (GSS) and stored at $4^{\circ}C$ for 16 weeks. Quality characteristics and consumer acceptability were measured. Results: Titratable acidity was higher in SPTSS and rapidly increased (p<0.05) after 9 weeks in all groups during storage. Amino-type nitrogen contents of SPTSS and SPKSS were the highest and rapidly increased (p<0.05) after 5 weeks. Total free sugar content was higher in GRSS and did not change during storage. Glutamic acid and total free amino acid contents were higher in SPTSS, SPKSS and continuously increased up to 9 weeks. Yeast counts rapidly increased (p<0.05) after 9 weeks reaching 4.0 Log CFU/g in all groups except for SPTSS. Consumer acceptability did not change during storage in all groups and GSS was least preferable. Conclusion: The optimal quality maintenance period of ssamjang with cheonggukjang and jocheong was determined to 7-9 weeks of storage at $4^{\circ}C$ and ginger jocheong was the least preferable materials. We conclude that it is possible to develop easy-made ssamjang products with cheonggukjang and non-fermented materials also skipping aging period.

  • Ssamjang samples were prepared by central composite design for five independent variables, Gochujang mash aging period $(X_1)$, Doenjang aging period $(X_2)$, Doenjang content $(X_3)$, sterilization temperature $(X_4)$ and storage temperature $(X_5)$. Browning characteristics of Ssamjang were analyzed such as water activity, free amino acids, free sugars and color during storage. Water activities of Ssamjang were ranged from 0.605 to 0.666 at the beginning of storage, and were shown to be the highest at the 8th week of storage and then decreased gradually. Among free amino acids the content of glutamic acid was the highest. Proline, leucine, phenylalanine, lysine and serine were slightly higher than the others. Larger amounts of free amino acids and free sugars were observed from the sample sterilized at $60^{\circ}C$ when compared to that at $70^{\circ}C$. Glucose, fructose and maltose as free sugars were identified from Ssamjang and glucose content was the largest among. During the storage, lightness $(L^*)$, redness $(a^*)$ and yellowness $(b^*)$ of Ssamjang were decreased and total color difference $({\Delta}E)$ was increased. The color changes in the sample surface were more affected by temperature of which storage temperature was more influenced than sterilization temperature.

  • 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.

  • This study investigated the quality characteristics of factory-style ssamjang (FSS) and commercial handmade-style ssamjang (HSS) products. Moisture, crude protein, and crude fat contents were significantly higher in the HSS groups (49.37~62.12%, 9.39~13.46%, and 4.40~8.35%) than the FSS groups (41.94~45.83%, 7.50~9.09%, and 1.81~3.36%). Salt content was higher in the HSS groups (6.33~11.18%) than the FSS groups (6.10~7.57%). Moreover, the average salt content (7.51%) of the HSS groups and the FSS groups was lower than that of commercial ssamjang (8.73%). Hunter's color value was also significantly higher in the FSS groups. However, free sugar, organic acid, and free amino acids contents varied greatly between the FSS groups and the HSS groups, which was likely due to the different manufacturing method, ripening degree of doenjang and the main material used for ssamjang.

  • The study sought ways to promote the global recognition of Korean food items. The Korean cuisine is one of the healthiest and well-balanced foods in the world. There are world-wide sauces in the United States, China, Japan, Thailand, Vietnam and Cambodia, Singapore, Indonesia, India, Australia, British, France and Italy. The above mentioned countries have good sauces and marketing strategies. In contrast to those countries, the internalization of Korean-style sauce has not yet been carried out. In this study, globalization plans for Korean cuisine through Korean-style sauces are divided as follows: promotion of the existing Korean-style sauces such as soybean sauce, Gochujang, Doenjang and Ssamjang, to chefs in foreign countries; development of derivative sauces, based on Gochujang, Doenjang, and Ssamjang; overseas promotion of Korean-style sauces through foreign chefs in Korea; and overseas promotion of the existing Korean-style sauces. Development of indigenous sauces by Korean food manufacturers and processors is one route in the promotion of Korean cuisine. Korean franchising restaurants could also aid in export of Korean food items. The food manufacturing/processing sectors must work in concert with the Korean government to globalize the Korean cuisine. The government should play a leading role in fostering star chefs, holding Korean cuisine seminars along with promotional efforts in foreign countries and foreign cooking schools (such as the 'Taste Korea' campaign).

  • Marketing of traditional doenjang (a kind of fermented soybean product) is now focusing on its health advantages, being proven to have anti-viral, anti-cancer and anti-oxidant effects. The purpose of this study is to investigate the consumption patterns of traditional doenjang in the households managed by different generations of women living in Gyeonggi area. Six hundred housewives answered the questionnaire. Statistical analyses were performed on 590 subjects using SAS (ver 8.1). Chi-square tests and General Linear Models were used. The age distribution of housewives was as follows: 42.9% were in their 30s; 40.9% were in their 40s; and 16.2% were in their 50s. 57.5% of subjects graduated with high school education while 72.8% of subjects did housework only. Overall, 47.2%, prepared their doenjang themselves, while the remainder purchased it or received it from relatives. This percentage differed however according to age group, as self-preparation of doenjang was found in only 22% of housewives in their 30s, but increased to 83% of subjects in their 50s. 53.4% of subjects had their doenjang donated to them by relatives, compared with only 3.1 % of subjects in their 50s. Most of dishes using doenjang were soups and stews. Those housewives in their 50s made significantly higher use of doenjang in soup, wrapping vegetables (ssamjang), seasoning, and flat cake (jangttok). Doenjang dishes were prepared for the husband in the family 59.2% of the time, followed by housewives 15.4% of the time. Annual consumption of doenjang was 5.1kg. and Kanjang was 4.4L per household; there was no significant difference between the age groups respecting annual consumption. From such results, we may assume a decrease in home-made doenjang among younger generations and an increase in the amount of purchased doenjang. We can predict an increased need for doenjang of better quality. Also the development of new products such as ready-to-eat or fast food variants would better serve the trend towards convenience.

  • In this study, we compared diet related attributes such as food taste preference, food consumption frequency and nutrition intake between elderly residents in their 80's of areas in Jeollanam-do that are well known for longevity and those of a part of Seoul. Structured in-depth interviews were conducted by trained interviewers on 125 consented subjects (67 Jeonnam and 58 Seoul). Differences of groups were tested using Chi-square tests for nominal or ordinal data and t-tests and ANOVA tests for ratio data. The elderly from Jeonnam tended to sleep longer, express emotion more freely, and interact with others more often than those from Seoul. The elderly tended to prefer sweet or salty tastes, which might be highly related to serious health problems. The most frequently consumed foods were napa cabbage kimchi (2.19 times/day) and multigrain rice (1.99 times/day). Elderly from Jeonnam tended to consume garlic, milk, beans and roasted barley/corn teas less often; whereas, they consumed porridge, dried radish greens, potato, fermented fish, dried fish, pork rib, pork belly, soybean paste soup, soybean paste/Ssamjang, other kimchis, pickled vegetables, snacks, cookies, and green/black teas more often than elderly residents from Seoul. Differences in nutrition intake between the regions were greater than differences between the perceived levels of household economic status. NAR and INQ for folate were lower among elderly from Jeonnam than those from Seoul, while those for protein, vitamin C, niacin, vitamin $B_6$ were higher. The study results indicated that elderly from Jeonnam engaged in a more diverse diet than the elderly from Seoul.
