This study examined the effect of gamma irradiation on shelf-life extension and sensory characteristics of dak-galbi. Commercial dak-galbi sauce was gamma-irradiated at 0, 5, 10, 15, 20, 25, and 30 kGy. The dak-galbi sauce (200 g) was then added to diced chicken (800 g) for cooking, and the cooked dak-galbi samples in vacuum bags were stored at $35^{\circ}C$ for 5 d. Dak-galbi samples were analyzed on d 0, 1, 2, 3, 4, and 5 for microbial analysis (plate count agar), thiobarbituric acid (TBARS) and volatile basic nitrogen (VBN) measurements, and on d 0 for sensory evaluation. On d 0, total bacterial populations were below detection limit after dak-galbi marinated with the gamma-irradiated (${\geq}15\;kGy$) sauces were cooked, and the samples marinated with higher dose irradiated dak-galbi sauce had lower (p<0.05) bacterial populations during storage. TBARS values of the dak-galbi samples marinated with non-irradiated sauce were not different ($p{\geq}0.05$) with those marinated with irradiated sauces on d 0, and the TBARS values increased (p<0.05) during storage at $35^{\circ}C$, regardless of irradiation dose. In the VBN analysis, there was no difference ($p{\geq}0.05$) in VBN values among irradiation doses on d 0, but VBN values decreased (p<0.05) as irradiation dose increased during storage. Moreover, there were no significant differences ($p{\geq}0.05$) in sensory characteristics among irradiation doses. These results indicate that use of gamma irradiation on dak-galbi sauce may be useful in shelf-life extension without compromising the sensory characteristics of dak-galbi.

This study aimed to enhance the quality and sensory acceptability of dak-galbi sauce made from general tomatoes, plum tomatoes and canned tomatoes and find the most preferred quality characteristics and tomato type for the production of dak-galbi sauce. Dak-galbi sauce was blended with different concentrations of tomatoes (0%, 10%, 20%, 30%, 40%). As the amount of a tomato addition increased, the moisture contents, L-values, a-values and B-values significantly(p<0.001) increased while salinity, sugar contents and viscosity decreased. The attribute difference test showed that significant differences in such properties as color intensity, pungent flavor, pungent taste, mouthfeel were observed with more tomatoes added. Based on the results of this study, the optimal tomato content for maximizing the overall quality of dak-galbi sauce was 10~20% of general tomatoes or 20% of plum and canned tomatoes. More various kinds of dak-galbi sauce are expected to be developed through this study.

This study separated different factors into the Korean Wave and Korean health food according to the interest in Korean culture among the Chinese living in China. We then conducted a two-step cluster analysis with gender, marriage status, academic background, interest in Korean culture, command of the Korean language and the status of having visited Korea as variables. The subjects were split into a Korean wave-preferring group, highly interested in Korean food as health food group and a low interested group according to clusters, and we then investigated for preference differences for 20 Korean food dishes. Between these two groups the statistics indicated a significant influence with a level p<0.001 for Bulgogi, Bibimbap, Kimchi, Galbi-tang, Galbi-gui, Chicken, Samgyepsal, Doenjang-Jjgae, Dak-galbi, Japchae and Gimbap p<0.01 for Samgye-tang and p<0.05 for Naengmyeon, Kimchi-Jjigae, Dak-galbi, Seolleongtang, Haemul-tang, Hanjeongsik and Tteok-bokki. Jeon and Juk did not show any statistically significant difference. Chinese consumers preferred Korean food for Samgyeopsal, Bulgogi and chicken and less preferred gruel, Hanjeongsik and Kimchi-Jjigae. The highly interested in Korean culture group preferred Samgyeopal, Bulgogi and Chicken, and less preferred Juk, Jeon and Hanjeonsik in that order. This study offers information on the Chinese's preference for different Korean food to any food service enterprises that manage Korean restaurants in China or that sell Korean cuisine and also basic data for differentiated marketing to those entering the Chinese market.

This study aimed to investigate the perception and preferences related to Korean food according to the ethnicity of university students in Yanbian, China. Korean food was preferred by Korean-Chinese as compared with Chinese students, and Korean-Chinese students preferred Korean food more than Chinese food. Both Korean-Chinese and Chinese preferred Korean food more than traditional Chosun food. More Korean-Chinese than Chinese students had positive perceptions of Korean food, which included foods made with jang, kimchi smell, and healthiness due to diversity. For evaluation of Korean food taste, more Chinese than Korean-Chinese subjects thought Korean food is not greasy and hoped salty taste. Both awareness and preferences related to Korean food were significantly higher in Korean-Chinese than Chinese students. Meat foods (so-galbi, dak-galbi, jang-jorim) were relatively high in terms of preference in both Korean-Chinese and Chinese students. Moreover, Chinese students preferred Korean traditional foods (sujeonggwa, yakgwa, gangjeong). In Korean-Chinese students, Korean representative traditional foods (kimchi, jangajji) and Korean traditional holiday foods (tteokguk, mandu-guk) were relatively low in terms of preference. This study found that the traditional food culture of Korean-Chinese has been maintained in Yanbian, whereas there is a change in the young generation.

This study aimed to investigate the perception and preferences related to Korean food of university students in Yanbian, China. Self-administered questionnaires were collected from 306 (124 males and 182 females) students. The preferences for Chinese food (44.7%) and a combination of Korean (32.0%) and Chosun food (12.4%) were similar, and Korean food was more preferred than traditional Chosun food. The main reason for preferences for Korean food was taste. The perception of Korean hot spices and kimchi smell was not good, whereas positive perceptions where held for foods made with jang, new Korean food experience and healthiness of Korean food. Awareness of Korean food was in the order of bibimbap, kimchi-bokkeum-bap, gimbap, baechi-kimchi and ttoe-bbokki. Preference order was bulgogi, so-galbi, jang-jorim, dak-galbi and dewaeji-galbil. Meat foods and Korean traditional foods were relatively high, whereas kimchi, ttoe-bbokki and bibimbap were relatively low in terms of preference. More female than male students preferred Korean food, and the perception of new food experience and healthiness of Korean food were positive. Moreover, both awareness and preference related to Korean food were significantly higher in female than male students. These results can be used as a foundation to prepare a localization strategy of Korean food to China.

The purpose of this study was to select 30 representative Korean dishes by a systematic review of preferences and recognition of Korean foods. The papers for the review were located using the keywords 'hansik', 'hanguk eumsik' from DBpia, KISS, NDSL and RISS, and 18 relevant papers were finally short-listed. To analyze the preferences of Koreans and foreigners for Korean dishes, respondents were chosen from various regions such as Asia, Europe, South Pacific, Africa, and North/South America. A total of 4,053 respondents participated in the selected papers and Korean dishes were classified according to the content analysis based on books published by the Rural Development Administration (RDA). Among the main dishes, two kinds of cooked rice were selected, bibimbap and kimbap. Also, noodles, dumplings, and sliced rice cake soup varieties mul-naengmyeon, guksujangguk, mandu, and tteokguk were selected as main dishes. The side dishes selected included 6 kinds of soup, miyeokguk, yukgaejang, samgyetang, gomtang, seolleongtang, and galbi-tang. Other side dishes selected were six types of stews namely doenjang-jjigae, kimchi-jjigae, sundubu-jjigae, haemultang, maeuntang, and dakbokkeum-tang. Three kinds of grilled side dishes selected were bulgogi, galbi-gui, and samgyeopsal-gui. Galbi-jjim was selected in the category of braised or steamed foods. Tteokbokki and japchae were the stir-fried food selected. Pan-fried foods and fried foods selected included a kind of haemul-pajeon and dak-gangjeong respectively. Seasoned vegetables selected were samsaek-namul including gosari-namul, sigeumchi-namul and doraji-namul. Two kinds of baechukimchi and kkakdugi were selected as kimchies, and sikhye was selected in the category of beverages and teas. These results could be used as selection criteria in developing recipes for representative Korean menus.

n this study, the BMI characteristics and food preference were examined according to the Sasang constitution typology. The constitution type of the subjects was judged by SCAT2 (SC) and Sasang specialists (SP), and the data were compared with the group (SS) in which the two results coincided. The results of SC and SP were consistent with 55 (38.2%) out of 144 subjects. Among the 55 subjects, there were 36 (65.5%), 15 (27.2%), and 4 (7.3%) Soeumin, Taeeumin, and Soyangin, respectively. The BMI of Taeeumin was significantly higher than that of Soeumin (p< .001) in all analytical methods. On the other hand, there was a difference in determining the body shape of Soyangin between the SCAT2 and specialists. The Taeeum-Soeum Food Preference Index was applied to compare the food preference to 41 types of food. In SS analysis, 13 kinds of foods preferred by Taeeumin or Soeumin were found, of which 8 (19.5%) were consistent with the existing food data. Taeeumin preferred 6 kinds of food, such as cold soybean-soup noodles, wild sesame seaweed soup, pan-fried tofu, Yeongun-jorim, Doraji-namul, and soy milk. In contrast, the favorite foods of Soeumin were black rice and Dak-galbi.

The purpose of the present study is to assess nutrient content for providing nutrition information such as nutrition labeling on Korean dishes in restaurant and food service institutions. The content of nutrients was calculated in recipies used to prepare dishes which has been frequently consumed in such four groups as the literature, foodservice institutions of industries, restaurants, and households. The numbers of dishes surveyed were 15. Total numbers of literture used for recipies analysis are 20. Recipies used in foodservice institutions of industries were abstracted from the journal 'Guk-Min Young-Yang' published in Korea dietetic association and obtained with the help of dietitians working in those institutions. Also, recipies has been using in restaurants were given from the Korea restaurant association. Recipies in households was calculated from the secondary analysis of the Korean National Nutrition Survey. Nutrient content from foods except steamed rice and side dishes in each dish was calculated using data of Korean food composition table published. The content of energy and protein in 'Gal-bi tang' (beef-rib soup) were highest in recipes used at restaurants, vitamin C in recipes of food service institutions of industries due to the generous use of meats and vegetables than other recipies. 'Doen-jang chigae' (soybean paste stew) showed the lowest content of energy in results analyzing recipes presented on the literature and varied protein level by four groups for difference of protein source used. The content of energy in 'Gop-chang jeongol' (small intestines stew) is 150 kcal more than 'Soegogi jeongol' (beef stew) in general. The energy level of 'Daeji-galbi' jim (braised pork ribs) and 'Dak jim' (braised chicken) turned out to be the highest in recipies presented on literature. Variation of each nutrient content including energy and protein was relatively high, since some of foods used in 'Pibimbab' (mixed rice) varied with four groups. Amounts of energy and protein in 'Naeng-myeun' (cold noodles) is the highest in recipies of foodservice institution of industries because much amounts of noodle and meats were used comparing to other groups. The average content of energy in 'Pulgogi' (grilled meat with sauce) was 50% to Korea recommended amounts of one meal, 833.3 kcal. Content of vitamin $B_1$ in 'Jeuk pyeunuk' (boiled pork), which is made of pork meat, was higher than other dishes. The ingredients of frequently consumed Korean dishes were highly variable among the four groups which inevitably results in variation of nutrient content in each dishes. The high variation of nutrient content in each dish according to study requires careful collecting of the large number of recipies in presenting representative nutrient content for nutrition labeling on dishes in restaurant and food service institutions effectively.
