Jeon refers to a type of Korean cuisine used as a side dish, made with various ingredients such as meat, vegetables, or fish, mixed with flour batter and coated with egg batter and then pan-fried on both sides with oil so that heat spreads through them well. The aim of this study was to provide a cornerstone of further research on Korean dietary life, by reviewing types, recipes and names of Jeon recorded in ancient cookbooks (Korean literatures) and by analyzing changes in recipes to make Jeon, which our ancestors used wisely as one type of side dish. Considering developments and changes recorded in old documents, the Jeon recipe appeared relatively later than the recipes for grilling, steaming et al, which had been developed much earlier, and it had not been recorded until the 1600s. Changes of Jeon recipes by time period are as follows. In the 1600s, there were three recipes: frying only with grain batter after preparation of ingredients, frying right after preparation of ingredients, and putting ingredients on already fried watery batter. These three recipes were still used in the 1700s, in addition to a new recipe, in which ingredients were oil-fried to be skewered. Today's recipe in which prepared ingredients are fried after getting coated with flour and egg only appeared in 1800s. This has been the main recipe for Jeon ever since. In that time period, there was more variety of recipes and ingredients than before. For instance, Jeon was used for soup or steamed dishes instead of being served as a dish itself. Buchimgae with mixed ingredients was also considered Jeon. In the 1900s, there appeared more names for Jeon as more sorts of ingredients got used, even though there were no new recipes for Jeon. The above-mentioned historical records show that traditional recipes for Jeon have been applied to various dishes, using diverse ingredients, and it might be a smart solution to today's problematic dietary habits involving excessive intake of nutrients, in that it provides a healthy way to add fat. In the same sense, the recipe for Jeon can play an active role in internationalization of Korean foods, in which healthiness is a main feature. According to ancient documents, the recipes for Jeon were used even for meals that were not side dishes, such as Jun-Gwa (Jung-Gwa), Jun-Yak and fried rice-cake. Also, there were dishes using the same recipes even without carrying the name of Jeon, like Buchim or Jijim. This might be worthy of further examination in culinary science.

This study was performed to investigate the effects of lactic-fermented rice flour on the quality characteristics of pan-fried food (Jeon). Pan-frying flour containing 5~20% lactic fermentation rice flour mixture was prepared. In rapid visco analyzer examination, peak viscosity, trough, final viscosity, breakdown, and setback of the lactic-fermented rice flour mixture were lower than those of rice flour or wheat flour. The L-value (lightness) of Jeon decreased with increasing the ratio of lactic-fermented rice flour. On the other hand, a-value (redness) and b-value (yellowness) increased with increasing ratio of lactic-fermented rice flour. Texture profiles showed that Jeon prepared with lactic-fermented rice flour mixture had higher springiness and gumminess than 100% rice flour. The oil absorptions of Jeon prepared with 100% rice flour and 20% lactic-fermented rice flour were 7.5% and 6.33%, respectively. For digestive properties, Jeon prepared with lactic-fermented rice mixture showed a greater amount of rapidly digestible starch and lower amount of slowly digestible starch. In the sensory evaluation, Jeon prepared with lactic-fermented rice mixture showed higher scores for appearance, flavor, and taste than others (rice flour and wheat flour). Especially, Jeon prepared with 10% lactic-fermented rice mixture showed the highest overall preference. In conclusion, the results demonstrate that lactic-fermented rice flour may prove quite useful as a pan-frying flour with desirable qualities properties.

To measure nutritional components and physical quality of Wanja-jeon(Korean pan fried meat balls)was investigated during storage in a simulated hospital cook/chill foodservice system. The Wanja-jeon was cooked and stored for 4 weeks in chill conditions of 2 and 7$^{\circ}C$ and then reheated in the microwave oven. Moisture, protein, and fat contents were decreased little during 4 weeks storage at 2 and 7$^{\circ}C$. Total unsaturated fatty acids(TUFA) and polyunsaturated fatty acids(PUFA) increased slightly at 7$^{\circ}C$ storage. Total free amino acid contents were reduced after 4 weeks of storage, while total amino acids were affected little during chilled storage. However, volatile basic nitrogen(VBN) increased during the 4 weeks storage from 11.2mg%, immediately after cooking, to 14.1~14.2mg%. After reheating, thiobarbituric acid(TBA) value increased more significantly to 0.19 and 0.20.

The purpose of this study was to develop a fusion-food cooking program and apply that to sixth grade elementary school students, and to investigate its' effects on their knowledge, preferences, and perceptions of Korean traditional foods. The program focused on ten components. Students learned the general features of Korean traditional foods and Western foods in the 1st lesson. They learnt about kinds, nutrition value, and histories of kimchi, Tteok (rice cake), and Jeon (pan fried food), and cooked two fusion-foods of kimchi, Tteok, and Jeon each. As a result of learning about those food items, the students advanced their knowledge (p < 0.001) of kimchi, Tteok, and Jeon. Their preferences for Tteok (p < 0.05) and Jeon (p < 0.01) were increased, but those for kimchi remained unchanged. The interest (p < 0.05) and preferences (p < 0.01) for the general Korean traditional foods were increased. In conclusion, our results suggested that the fusion-food cooking program had the ability to improve elementary school students' perceptions of Korean traditional foods by increasing their knowledge, preferences, and interest in them. Furthermore it was considered that the program could help students understand the value of Korean traditional foods and in turn may encourage them to consume such food items more frequently. Since the fusion-food cooking activity program can be a good learning program as shown by the results of this study, more fusion-foods cooking activity programs, which are not discussed in this study, should be evaluated and developed in the future.
