The changes in ingredients, seasonings and cooking methods of Japchae in Korean cook books published from the 1600s to the 1960s were investigated in this study. Japchae was a royal dish enjoyed by Kwanhaegun of Joseon Dynasty and interesting historical story is contained in it. Kwanghaegun Ilgi in 1608 showed that Japchae was Kwanghaegun's favorite dish. Therefore, it has been thought that Japchae was created in the 17th century. Wonhaengeulmyojeongrieugye in 1796 described bellflower Japchae and mungbean sprout Japchae. The traditional Japchae was made without glass noodle called dangmyeon. Eumsikdimibang in 1670 first introduced traditional Japchae, which was made with 20 different ingredients and then served with topping sauce made of pheasant broth, strained soybean paste and wheat flour. Japchae in Kyugonyoram(1896) was prepared by mixing mungbean sprout, watercress, gonjasoni, tripe and yukhwe with mustard. The current style Japchae with glass noodle first appeared in the 1920s and became popular in the 1950s because the traditional Japchae was described in cook books until the 1940s. There were two ways of preparing current style Japchae. Yijogungjeongyoritonggo in 1957 described Japchae was made by mixing the boiled glass noodle with other ingredients and seasonings together. On the other hand, Japchae in Urinaraeumsikmandeuneunbeob(1960) was prepared by seasoning first with other ingredients, and then mixing boiled glass noodle. A variety of ingredients - vegetables, mushrooms, meat, fish, pheasant, beef tong, sea cucumber, gonjasoni and pear - has been used to prepare Japchae. Japchae has been seasoned with ginger, soy sauce, black pepper, sesame salt, sesame oil, oil, leek, garlic, salt, sugar, vinegar and mustard. Egg strips, pine nut, thin strips of Shiitake and stone mushroom, red pepper threads, Chinese pepper(cheoncho), black pepper and ginger were used for garnishing.

In this study, Jeonju bibimbap, Bulgogi, Japchae, Whangpomuk, Kimchijeyukbokkeum, and Sangseonjeon were selected as examples of take-out style Korean foods, and sensory evaluations on a 9-point hedonic scale were conducted with dining staff at UCLA. 54.5% of the respondents in this study were male and 62.7% were Hispanic/Latino, with the respondents fairly evenly split across age groups in a range of 25-54 years. In the sensory evaluation, the most acceptable items were judged as follows: Bulgogi (8.1)>Japchae (7.5)>Sangseonjeon (7.4)>Jeonjubibimbap=kimchijeyukbokkeum (7.3)>Whangpomuk (6.9). Among the 6 Korean foods (Jeonjubibimbap, Bulgogi, Japchae, Whangpomuk, Kimchijeyukbokkeum and Sangseonjeon), Bulgogi, and Saengseonjeon were the most acceptable items for the female and male respondents, respectively. All of the items were popular with the majority of the responding age groups, with the exception of the 18-24-year groups; in particular, Kimchijeyukbokkeum and Bulgogi scored relatively high on acceptability (7.0) for all respondents. Jeonjubibimbap, Japchae, Whangpomuk, and Saengseonjeon were also found to be acceptable to all respondents except for the African American respondents. We suggest that the Korean foods listed above are applicable items for quick service restaurants in the U.S. market.

The objectives of this study were to develop Korean dishes acceptable for quick-service Korean food restaurant franchising operations in the U.S. and to test consumer preferences of 6 Korean dishes developed. One hundred American consumers evaluated beef(Bulgogi), pork(Jeyuk-bokkeum), chicken(Dagkalbi), noodles with seasoned vegetables(Japchae), braised tofu(Dubujorim), and stir-fried kimchi (Kimchi-bokkeum). Consumer preferences for color and aroma of the three dishes(Bulgogi, Jeyuk-bokkeum and Dagkalbi) were not different with most indicating they liked these attributes. Bulgogi was preferred over Dagkalbi and Jeyuk-bokkeum was least acceptable. Consumers rated the flavor of the Bulgogi from a little too mild to just right while both the Dagkalbi and Jeyuk-bokkeum were rated from just right to too strong. Overall acceptance was inversely related to spiciness. Bulgogi and Dagkalbi were ranked significantly higher than Jeyuk-bokkeum with Bulgogi receiving a slightly higher score. Overall acceptance was higher for the Japchae than the Kimchi-bokkeum. Dubujorim was intermediate and not preferred or disliked more than either of the others. Consumers rated the flavor of the Japchae and the Dubujorim higher than the Kimchi-bokkeum, indicating that the flavor of the Kimchi-bokkeum was too strong. Almost half indicated both the Dubujorim and Kimchi-bokkeum were slightly or much too hot. The Japchae and the Dubujorim were ranked equally high and significantly higher than the Kimchi-bokkeum. We suggest that control of spiciness is a main factor to develop Korean dishes acceptable for quick-service Korean food restaurant franchising operations in the U.S.

본 연구는 조리과정 중에 Salmonella 식중독균수가 어떻게 변화되는지를 관찰하고, 이를 토대로 HAPPC model 설정을 위한 실증 자료를 제공하고자 수행되었다. 돼지고기(크기: $0.5cm\;{\times}\;10cm\;{\times}\;10cm$, 무게 : 약 25g) 에 살모넬라균 (S. typhimurium)을 $10^{7}\;CFU/g$으로 오염시키고 조리하는 과정(해동 방법, 해동기간 및 조리방법)에서 균수의 증가 또는 감소를 관찰하였으며, 오염된 돼지고기를 사용하여 한국인이 일상적으로 많이 먹는 돼지고기 음식(잡채)을 만드는 모의실험을 통하여 이 음식물에서 최종적인 균수를 측정하였다. 해동 방법별로는 24시간 후에 균수가 냉장 온도 ($4~10^{\circ}C$)에서 $10^{10}\;CFU/g$, 실온($22~29^{\circ}C$)에서 $10^{21}\;CFU/g$의 수준으로 증가하였다. 전자레인지에 의한 급속 해동(40초)에서는 균수가 가장 낮게 측정되었으나 $10^{8}\;CFU/g$으로 역시 증가하였다. 해동 기간별로 냉장과 실온에서의 균수 변화를 보면 균수는 시간이 경과될수록 뚜렷이 증가를 나타내었다. 냉장온도에서 해동시에는 24시간 후에 1010CFU/g , 48시간 후에 1013CFU/g, 72시간 후에 $10^{20}\;CFU/g$의 수준으로 증가하였다. 실온 해동시 2시간 후에는 $10^{10}\;CFU/g$ 수준, 4시간 후에슨 $10^{15}\;CFU/g$ 수준, 8시간 후에는 $10^{16}\;CFU/g$ 수준, 12시간 후에슨 $10^{18}\;CFU/g$ 수준, 그리고 24시간 후에는 $10^{21}\;CFU/g$ 수준으로 증가하였다. 조리방법별로는 돼지고기를 볶기 ($150{\pm}7^{\circ}C$, 3분) 한 결과 균수는 $10^{6}\;CFU/g$ 수준으로 초기보다 약간 감소하였다. 삶기(20분) 한 결과 $60^{\circ}C$에서는 초기와 같은 $10^{7}\;CFU/g$ 수준, $63^{\circ}C$에서는 $10^{6}\;CFU/g$ 수준으로 볶기에서의 균수와 같게 나타났으며, $65^{\circ}C$에서는 $10^{4}\;CFU/g$ 으로 감소하였다. S. typhimurium에 오염된 돼지고기를 위와 같이 볶은것($10^{6}\;CFU/g$)을 사용하여 잡채를 만든 결과 (소요시간 :10{\pm}2분)균수가 $10^{7}\;CFU/g$으로 증가하여 Salmonella 식중독의 발생 위험성이 더욱 커진 것으로 나타났다. 이러한 결과로 볼 때 돼지고기에서는 S. typhimurium의 증식은 조리과정에 의하여 영향을 받는 것을 알 수 있다. 식중독을 야기할 수 있는 수준으로 오염된 돼지고기를 조리할 때에는 $65^{\circ}C$에서 20분 이상 삶아야만 식중독 발생 예방이 가능한 것으로 사려되었다. 또한 이상과 같은 결과로부터 이 잡채에 대한 위해분석(HA)에서 원재료 고기의 초기 미생물 오염도가 위해요소(hazard)로 지적되며, 부적절한 조리단계(조리방법 및 조리온도와 시간)과 중점관리점(CCP)으로 판명된다. 잡채의 경우 돼지고기를 볶아서 사용하는 경우가 많으므로 이 조리방법의 표준화(고기의 크기와 양에 따른 온도/시간/조리방법)가 필요하다.

This study researched microbial change of quality according to the various phases of product flow of cooked pea and rice, cold cucumber and seaweed soup, soybean sprouts japchae feeding urban type of a commissary school and a satellite school in Daejeon area, also it suggested the possibility that the central commissary foodservice system can be established and utilized more developmental to identify its food of variation of temperature and state of safety unitl 3 hours after cooking for the case of delay of distribution and holding because of the satellite school of geographical location and traffic problem. The critical Control Points identified for each category of menu items were: Boiled pea and rice: inadequate distribution, holding and storing before assembly; Cold cucumber and seaweed soup: pre-preparation and post-preparation after cooking; Soybean sprouts japchae: Pre-preparation, post-preparation and storing. As the result of observation of the variation of temperature and microbial safety according to the delay of distribution and holding for each food, all of them were relatively safe until 3 hours after cooking, but cold cucumber and seaweed soup being stored for 3 hours, the value of E. coli is $10^3$ CFU/g. The variation of temperature was more extreme in soybean sprouts japchae than cooked pea and rice and cold cucumber and seaweed soup. It was proved that the stainless container was excellent and that adequate holding container should be used.

Purpose: This study assesses Korean royal court cuisine as perceived by culinary professionals and students for the development of Korean dining. Methods: It was observed in a survey that Korean royal cuisine could be grouped into four classes represented by the following factors: popularity, standardization, tradition, and haute-cuisine. Results: From the analysis of the survey results, it was determined that the people surveyed could be grouped into the following three categories: those who prefer standardization/pursuit of haute-cuisine, traditionalists/popularizers, and those who are indifferent. The survey also assessed whether the ten most popular Korean dishes served to foreigners had variations in royal court cuisine and which food ingredients and combinations of dishes would be the most appropriate. It was determined that control over the sweetness when cooking Bulgogi was needed. For food usually consumed for invigoration, especially for the broth of soup dishes in summer, women preferred clear meat broth with soup than men. When preparing Japchae, it was found that control over the ratio between glass noodles and vegetables and control over the sweetness were needed with respect to the main dishes. Conclusion: The indicator 'education on Korean royal court cuisine culture' showed relatively low satisfaction compared to its high importance, implying that further improvement in these development measures is especially required.

This study was conducted to explore portion size estimation by comparing the measurement errors of food and macronutrient intake by photography estimation and 24-hour recall from weighing method. A total of 28 female participants aged 20-24 years old were provided a meal that included rice, chard soup with soybean paste, stir-fried squid, japchae, stir-fried boiled fish paste, lettuce geotjeori, and kimchi. Each portion was measured accurately, and food intake was measured using three dietary assessment methods. For the photography method, trained researchers estimated remaining food amount by analyzing photographs using a mean of four times. The measurement errors for the stir-fried squid and japchae were larger by the 24-hour recall method, while the error for kimchi was larger by the photography method. The correlation coefficients for each food, except chard soup with soybean paste, between the weighing method and photography method were 0.77~0.99 (p<0.001). The correlation coefficients of energy and intake of macronutrients between the weighing method and photography method were 0.85~0.86 (p<0.001). The results of this study demonstrate substantially less measurement error using the photography method than the 24-hour recall method. However, further research is needed to standardize various kinds of foods, photograph angles, serving plates, and serving style for establishment of reliable and valid portion size estimation using the photography method.

To establish a globalization strategy for Korean food, it is important to ascertain foreign consumer's taste preferences and to evaluate their sensory perceptions of Korean food. In concert with previous studies, the most preferred food were Bulgogi and Galbi. However, respondents showed somewhat different preferences for other foods. Chinese and other Asian participants preferred Galbitang and Samgyetang, while Japanese participants preferred Pajeon, Galbitang and Japchae, and Western participants preferred Galbitang, Mandu and Bibimbap. The most preferred condiment was hot pepper paste (the representative condiment of Korea) and the least preferred one was ginger. Hot pepper paste was preferred most by Japanese participants, while Chinese participants tended not to prefer ginger and other Asian participants excepting those from China and Japan disliked vinegar most. Foreign consumers tended to consider Korean food as sweet, salty and very hot. Chinese participants considered Korean food to be 'plain' and 'light and washy' in taste, while Japanese participants considered Korean food to be 'greasy' and 'thick and sticky'. Chinese participants considered typical servings to be inadequate, while Japanese participants considered the servings as excessive.
