This study was conducted to evaluate the baking characteristics of yellow layer cake containing chlorella powder. Chlorella at concentrations of 0, 4, 8, 12, and 16%(w/w) wheat powder were added, after which we evaluated the baking characteristics, physical properties, and sensory properties of the resulting cakes. Regarding the weight and volume of the cakes, the treatment groups were similar. However, control showed a high hardness value while 16% chlorella added cake showed a significantly low value. The 4% and 8% chlorella added groups maintained their structural condition while the 12% and 16% chlorella added groups were softer depending on the protein content of the flour, Lightness(L value) and yellowness(b value) of the cake crumbs became lower depending on the concentration of chlorella, whereas redness(a value) decreased. In the sensory test, the acceptability scores of the 12% and 16% chlorella added groups were lower compared to control while the 4% and 8% chlorella added groups had higher scores. Therefore, chlorella powder added yellow layer cake exhibited more functionality as well as higher quality.

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 investigated retrogradation properties of Jeungpyun substituted for cereals with dietary fibers of 60% of brown rice, and barley. Quality changes during storage periods of the functional Jeungpyun, were studied using $\alpha$-amylase iodine enzyme digestion methods, X-ray diffraction patterns, and differential scanning calorimetry (DSC). The barley substituted samples showed significantly lower retrogrdation rates than those of control when examined by $\alpha$-amylase method. The Relative crystallity by X-ray diffraction patterns had typical A type in all samples with appealing big crystallity around its diffraction angle 23$^{\circ}$degrees as storage periods were increased. The brown rice and barley Jeunpyun made smaller crystallity than that of control, representing slower retrogradation rates. The batter controls had significantly lower ΔH than the other compared samples when measured by DSC, but had significantly higher ΔH after 30 days of storage, implying that the control required more energy for regelatinization after the 30 days of storage.
