In this study, the content of water-soluble vitamins such as vitamin B1 (thiamin), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B12 (cyanocobalamin), and C (ascorbic acid) in dishes containing meat and seafood consumed in Korea were determined by high-performance liquid chromatography (HPLC) with ultraviolet and fluorescence detection. All analyses were performed under strict quality control of vitamins B1, B2, B3, B5, B6, B7, B12, and C. The highest content of vitamin B1 was observed in Bugeo-gangjeong (1.373 mg/100 g) and the highest level of vitamin B2 (5.162 mg/100 g) was found in pig liver. Bugeo-gangjeong showed the highest content of vitamin B3 (21.676 mg/100 g), and kkomak-muchim contained considerable amounts (43.310 mg/100 g) of vitamin B5. Vitamin B6 was not detected in most seafood dishes except for yangnyeom myeongran-jeot (0.274 mg/100 g) and was present at low levels or not present at all in meat dishes. The highest content of vitamin B7 was 6.506 μg/100 g in saeu-jeon and kkomak-muchim showed the highest content (21.132 μg/100 g) of vitamin B12. The highest content of vitamin C was in yangnyeom myeongran-jeot (84.508 mg/100 g). In addition, the analysis methods of each water-soluble vitamin were verified. These results showed that seafood-based ingredients in several dishes could be a good source of water-soluble vitamins.
This study was conducted to provide fundamental data for the Korean food service industry by researching the awareness and consumption tendencies of 180 domestic foreign residents towards Korean meat dishes. The results showed differences in the preferred types of food depending on gender; men tended to like meats, followed by stews, and rice, whereas women tended to like meats, followed by rice, and stew. The foreigners who participated in this research dined at Korean restaurants at least 20 times per month on average, regardless of their place of residence. Dishes with the lowest intake were suyuk (boiled meat, 66.7%) and dakbokkeumtang (sauteed chicken stew, 67.8%) and dishes with the highest intake tended to be roasts, which are relatively easier to prepare. The types of preferred food were in the order of galbi, bulgogi, and dakgalbi, and the least favored foods were yukgaejang, followed by suyuk, and seollengtang. "It is delicious" was the response found most frequently as a reason for preference regardless of the type of meat dish, and the reason for distaste was: "It is not delicious" This demonstrated that taste was the most important factor when visiting a Korean restaurant. Unexpectedly, sirloin roast, beef galbi stew, chicken stew, samgyetang, and dakbokumtang were not favored because of unfamiliar aroma and taste. In the case of galbi, "It is not very sanitary" was the main factor in responses. For areas of improvement, food sanitation, meat smells left on clothes, and smoke generated during roasting were factors with a high degree of importance, whereas the use of gas burners and the blackening of bowls were found to have a lower degree of importance.
This paper examines the dining tendencies of Koreans toward meat dishes and their related factors, with 301 people residing in Korea as subjects. We questioned this population on their restaurant choices, eating habits, preferences and a dislike with respect to method of cooking. All age groups, with the exception of 50~60 year-olds, were found to consume meat dishes in specialized restaurants. The selection factor for restaurants varied, depending on the age group: affordable cost was the most important factor for whom under 20 year-old. Whereas 20-40 year-old people considered taste and ambience the most for choosing restaurant. The 50-60 year-old people found to seek for convenient restaurant. In terms of the most preferred parts of beef, 20-30 year-old people preferred tenderloin (42.3%) while 40-60 year-old people preferred sirloin (45.6% and 41.2% each). All the other age groups preferred ribs the most (It was also found that) men preferred the rib parts and women preferred tenderloin. With respect to pork, all age groups preferred pork belly, with the highest response rate in the under 20 age group. When consuming meat dishes, 91.0% of respondents pointed to roasting as the most frequent preparation method, the reason being good taste was deemed the highest number of responses. In a survey on preference for stewed meats, 74.8% of the sample pool was found to prefer stew dishes but 24.9% of respondents provided negative answers, the reason for dislike was found to be poor taste for women, and both a long preparation time and poor taste for men. In fact, regardless of marital status, a high number of responses were given for poor taste as the reason for disliking stew dishes. Based on the examined factors for inconveniences in preparing meat dishes, the most common inconvenience factor was the odor of meat left on clothes after the dining experience, followed by the smoke generated in roasting meat, and the safety risk involved with changing the grill. In terms of stir fry preparation, the negative thoughts were due to the splashing of food and spices while cooking, followed by the meat odor left on clothes after dining experience, and the sanitation level of the cooking containers. For deep frying the sanitation level of cooking containers was the biggest reason for dislike, followed by splashing of food when preparing. Lastly, it was indicated that the problem of steaming method was a difficulty of judging the portion, on the top of this, people found that the sanitation level of cooking container and a long preparation time were also the problem of this cooking method.
