This study investigated the sensory characteristics and antioxidative activity of the reduced salt dried bulgogi bibimbap containing AF-343, a dandelion-derived compound extract. A sample with a 30% reduced salt had a sodium amount of 659.01 mg, which was significantly lower than that of the sample before the reduction (p<0.05). The textural hardness of the SW (Standard sample with the AF-343), showed the lowest value of 1.03 N/cm2, indicating that the AF-343-containing sample could have a slightly softer texture than the non-containing sample. In the analytical sensory test, the AF-343- containing samples showed a synergistic effect on the aroma and flavor of bulgogi, with values of 5.7 and 8.4, respectively, which were significantly higher than that of the non-containing sample group (4.3 and 4.4, respectively). The hardness by the sensory test was slightly hard with values of 7.2-8.1 in all samples, indicating that textural improvement was needed. In the acceptance test, all the samples scored with slightly lower values of 4-5 points, highlighting the need for future studies to improve the sensory characteristics of dried bibimbap. The flavonoid contents of AF-343-containing SW and RW sample groups were 68.21 and 64.31 mg GAE/100 g, respectively, which were significantly higher than those of the samples without AF-343 (49.06 and 44.82 mg GAE/100 g, respectively) (p<0.05). The ABTS and DPPH radical scavenging activities were similar to those of the flavonoid contents. As a result, in the production of AF-343-containing reduced-salt dried bulgogi bibimbap, more study on the textural improvement will be needed to achieve better palatability.

This study investigated the changes in the physicochemical properties of soybean sprout, radish, and pork loin during frozen Bibimbab production. The qualities of soybean sprout were affected by the blanching, thawing, and cooking processes, with the blanching process particularly regarded as an important process to attribute the overall quality of the soybean sprouts in the final product. High weight loss of radish was found in the thawing and cooking processes, while the weight loss was relatively lower than that of soybean sprout. However, mixing with hot rice can be attributed for the steep decrease in shear force of the radish. For pork meat, normally thermal treatment such as mixing with hot rice and cooking manifested quality deterioration. Based on the results, mixing process appeared to be the most important process which affected the final quality of the materials. To improve the quality of final frozen Bibimbab, therefore, it was recommended to freeze the food ingredient separately from rice prior to packaging, which warranted the follow up exploration.

We investigated the antioxidant, physicochemical, and sensory characteristics of dried type sodium-reduced bibimbap using dandelion complex powder (DCP). DCP is known to add moisture to the skin and relieve symptoms of atopic dermatitis. The sodium content of the standard sample was 1,110.87 mg per serving. The sodium was significantly reduced by 30%, resulting in 762.62 mg of sodium for the reduced sodium group (p<0.05). The ash contents of the standard sample group with DCP showed the highest value (3.17%) in all samples and was affected by minerals of DCP (p<0.05). The total flavonoid contents and ABTS radical scavenging activity, indicators of antioxidant, anticancer and antibacterial activities, showed significantly high activities with addition of DCP (p<0.05). In the sensory results, bulgogi and savory flavor of the samples with DCP showed significantly higher values, and samples with DCP received the highest scores for after-taste. All samples were confirmed to be microbiologically safe according to the food code applied to food manufacturers. Pathogenic microorganisms tests were either negative or not detected in all samples.

This study investigated the antioxidative activities and quality characteristics of Aster scaber Bibimbap as a home meal replacement with blanching (BASB) or without blanching (ASB) pretreatment. BASB samples at 5.0 g showed higher moisture, crude protein, and ash contents than the control (p<0.05). Color L, a, b-values of samples significantly decreased with increased content of Aster scaber powder (p<0.05). BASB samples showed lower hardness than ASB samples. BASB samples showed higher total phenolic content and DPPH radical scavenging activity than ASB samples. BASB samples showed higher sensory values for color, savory aroma, savory flavor, and aftertaste than ASB samples. Except for glossiness, BASB samples showed higher sensory acceptance scores than ASB samples. Sensory acceptance tests of all samples showed high scores for ‘usually like’, representing the possibility of successful development of Bibimbap as a home meal replacement, especially that containing blanching pre-treated Aster scaber powder.

In 2013, for the 130th anniversary of the establishment of diplomatic relations between Korea and Germany as well as the 50th anniversary of the dispatch of Korean workers to Germany, a survey on the recognition and preferences related to Bibimbab was carried out among students in Bayreuther, Germany majoring in hotel management who had not tried Korean food before. As part of the globalization of Korean food, 10 different foods that Germans might like were prepared, and the survey took place after food tasting. In the results, 44% of students noted that their first impression of Bibimbab was good, and impression was more favorable after tasting than before. The preference for nine foods other than Bibimbab was in order of Kimchi, Bulgogi, Mandu, Modum-jeon, Samgyetang, Gimbab, Japchae, Tteokbokki, and Sangchu-muchim. Students liked Bibimbab due to its healthiness, and most students showed interest in Korean food after tasting Bibimbab. To improve Bibimbab, most students answered diversifying sauces.

The purpose of this study was to investigate changes in the cooking process of Bibimbab(cooked rice mixed with various ingredients) appeared in cook books published after Korean modern era, approximately from late 19th century to the present. 7 cook books were chosen to be analyzed. It is found that the ingredients were mixed with the rice before being served in the cook books written in late 19th century until mid 20th century, while the ingredients were separately decorated on top of the rice in the cook books written from mid 20th century until late 20th century. Gochujang(Korean chilly paste), which is common spicy seasoning for Bibimbab in the present time, appeared only in Hangukeumak(1987) which is written in late 20th century. Prior to Hangukeumak(1987), chilly powder or chilly was used for chilly-based spicy seasoning. Cook books written in late 19th century until mid 20th century, ingredients used for Bibimbab had complicated cooking methods such as Jeonyueo(assorted pan-fried delicacies), Nurumi(fried beef skewer with various vegetables) and Sanjeok(grilled beef skewer). From mid 20th century until late 20th century, among the cook books analyzed in this research, only Hankukyoribaekguasajeon(1976) suggested Jeonyueo as an ingredient, and in general, the cooking method for preparing beef became simpler. For further studies, firstly, the cooking procedures used for Bibimbab in the prior period to the Korean modern era need to be examined for more information about the changes of cooking style of Bibimbab. Secondly, new Bibimbab recipes for modern restaurants could be created by using the recipes used in the historical cook books. Finally, the definitions of culinary terms used in historical cook books need to be clarified.

The purpose of this study was to divide into a few groups of Bibimbabs with distinctive menu patterns and accompaniments from 484 Bibimbab menus of 360 elementary school foodservices around Busan city and Gyeongnam province. The menus were collected from the internet(http://www.kdclub.com) and the home page of elementary schools from December, 2004 to September, 2005. Moreover, Bibimbabs with high frequency were analyzed by seasons and regions to give informations for menu planing and developing in elementary school foodservices. The serving frequency of Bibimbabs was significantly different among seasons, highest in summer and lowest in winter. Kongnamulbibimbab and Bomnamulbibimbab were highest in frequency in rural areas meanwhile, Sanchaebibimbab, and Chamchibibimbab were frequently served in Busan. The basic structure of Bibimbab meal based on main dish, soup, kimchi and one or two accompaniments consisted of 'side dish', 'fruit & beverage', or 'starchy food & dessert'. Thus, most of the Bibimbab meals were composed of 4~5 dishes. Five groups of Bibimbabs were suggested by the menu patterns and kinds of soups. Soups, fruit & beverage, and kimchi were included in the menu patterns of nearly all groups of Bibimbab. However, side dishes and strachy foods & desserts were included of excluded according to the groups of Bibimbabs. Some kinds of soups and side dishes were different among the groups of Bibimbab. These results suggest that the cost, avaliable labor and seasonal constraints contributed mainly to the numbers and kinds of accompainments in the Bibimbab meals. However, taste and sensory balance were also considered in the Bibimbab menus in the School Lunch Program.
