This study was conducted to evaluate the possible subacute toxicity of gamma-irradiated dried bibimbap. The dried bibimbap was irradiated at the dose of 30 kGy at room temperature. For the animal study, the male and female ICR mice (8 mice per group) had the diet with AIN39G as control and dried bibimbap 30 kGy irradiated and non-irradiated for three months. During the experimental period, the group with 30 kGy irradiated bibimbap did not show any changes in appearance, behavior, mortality, body weight, organ weight, and food consumption compared to the control. Also, all of the biochemical parameters were observed in the normal ranges. In histopathological examination including hematological and serum biochemical analyses, there were no significant differences among the control and 30 kGy irradiated dried bibimbap groups. These results indicate that irradiation of bibimbap up to 30 kGy did not cause any toxic effects and could be applied for the development of safe ready-to-cook food.

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.

The effects of the water extract of beef shank bones on the physical and sensory characteristics of cooked rice for JeonJu Bibimbap were investigated. Five kinds of cooked rice were prepared with 0%(control), 20%, 40%, 60%, and 100% of the beef shank bones extract. An increase in the beef shank bones extract concentration was associated with a lower moisture content of the cooked rice. The color(L, b value) of the cooked rice prepared with the beef shank bones extract became gradually darker during storage at $60^{\circ}C$. In regards to the textural properties of the cooked rice, the hardness increased with the addition of the beef shank bones extract and chewiness was changed in a similar pattern to that of hardness. However, the adhesiveness significantly decreased. In the sensory evaluation, the cooked rice prepared with 20 and 40% of the beef shank bones extract had the best sensory quality for JeonJu Bibimbap.

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 $1.03N/cm^2$, 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.

Nowadays the pursuit of health among people leads to the unceasing pursuit of healthy dishes. Although many kinds of ingredients which are not fatty are used in Korean dishes, Korean dishes has not been approved as healthy ones in foreign countries yet. This study considers the recognition of Korean dishes and Bibimbap. 299 Chinese students in Shenyang, China took part in this investigation. The results of this study state that 25 percent of respondents do not like Korean dishes while 27 percent of respondents do not like Bibimbap. And the respondents who dislike Korean dishes cite the reasons of its 'bad taste' and 'bad looks'. That is, in order to increase the popularity of Bibimbap and make Korean dishes as a domestic diet culture in China, we should know about the tastes and kinds of dishes that Chinese people like. Also, we should consider the reasons why Chinese people like and do not like, and then develop Bibimbap to make the majority of Chinese people like it.

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.

Pathogenic Escherichia coli is recognized as an important cause of diarrhea, hemorrhagic colitis and hemolytic-uremic syndrome worldwide. This study was conducted to investigate the prevalence E. coli contamination in the Korean traditional food bibimbap. E. coli were isolated from 84 of 1142 (7.3%) bibimbap investigated from 2005 to 2011. Antibiotic resistance profiling demonstrated that 6 of the 84 isolates (7.2%) showed multiple drug resistance. Fifteen virulence genes specific for pathogenic E. coli such as Shiga toxin-producing E. coli (STEC), enteropathogenic E. coli (EPEC), enterotoxigenic E. coli (ETEC), enteroinvasive E. coli (EIEC), and enteroaggregative E. coli (EAEC) were examined by multiplex PCR for mixed bacterial cultures derived from bibimbap samples. The EPEC virulence gene (ent) was detected in 5 strains (5.9%), while ETEC, EAEC, and EIEC were not detected. STEC serotypes O103 (1.2%), O91 (1.2%), and O128 (6.0%) were found, but other serogroups such as O26, O157, O145, O111 and O121 were not detecded. Automated Repetitive-Sequence-Based PCR analysis showed different patterns.

The purpose of this study was to evaluate the microbiological quality and assure the hygienic safety of the Bibimbap production in elementary school foodservice in accordance with the HACCP(Hazzard Analysis Critical Control Point) program. The time-temperature relationship and the microbiological quality(total plate count and coliform bacteria count) were assessed to find the critical control point(CCP) during each of the production phase. In the pre-preparation phase, the risk factors of the raw ingredients exceeded the standard level suggested by Solberg et al. Mungbean starch jelly, egg and Kochujang were satisfactory in that no coliform groups were observed over the standard TPC level. In particular, there was a high the risk of beef from the early stages in terms of the coliform level. In the pre-preparation phase, green pumpkin had more coliform groups than the standard level even after washed, which calls for special attention to washing, sterilization, secondary infection of the handler, and the required time for pre-preparation of raw vegetables. In the cooking phase, the temperature of the soybean sprout and mungbean starch jelly decreased to 42$^{\circ}C$ and 26$^{\circ}C$, respectively, which was within the risk zone. In particular, mungbean starch jelly had a great risk factor even after boiling in hot water. During the storage stage before serving, a lot of ingredients were exposed to poor management of temperature and time and thus exceeded the standard level in the total plate counts. In particular, the microbiological count of beef was five times the standard level. Green pumpkins and soybean sprouts were left at 15-38$^{\circ}C$ that is within the risk zone for a long period of time after they were cooked. It is highly recommended that the time of the storage stage before consumption should be shortened and that proper devices should be used to prevent proliferation of bacteria. The number of TPC of the utensils was satisfactory enough, but the knife used exceeded the standard level and thus was a risk factor of bacteria proliferation.

This study was prepared to present the research data for the promotion of Korean foods and restaurants in Korea and abroad by an analysis of the recognition and preference of Korean traditional foods and an importance-performance analysis of Korean restaurants by foreign visitors (n=351) and foreign residents (n=365). The most recognized Korean foods among foreigners were Bibimbap>Kimchi>Bulogi>Galbi>Samgyetang;however, the most preferred Korean foods were statistically different; Bibimbap>Kimchi>Bulgogi>Galbi>Rameyeon by foreign visitors and Bulgogi>Bibimbap>Galbi>Samgyetang>Kimchi by foreign residents. Especially, the preferences for Samgyetang and Dakgalbi were increased whereas that for Kimchi was decreased in foreign residents. The Korean foods were described as 'hot and pungent' and 'spicy' by foreign visitors, but 'hot and pungent', 'non-greasy' and 'salty' by foreign residents. In choosing a restaurant, 'quality of food' was most important among foreigners, but 'proper price' was considered more significant than 'sanitation and cleanness' by foreign residents compared with foreign visitors. The satisfaction with Korean restaurants of foreign residents was lower than that of foreign visitors. An analysis of importance and performance of Korean restaurants by foreigners was performed. There were significant differences in the evaluations of Korean restaurants between foreign visitors and foreign residents (p<0.05). The importance of the attributes related with 'foods' and 'sanitation' were rated higher by foreign residents. On the other hand, foreign visitors rated the importance of the attributes related to 'eating environment' and 'employees' more highly. Foreign residents significantly rated the performances of Korean restaurants lower in each attribute except 'additional free side dishes' and 'communications'.
