Physical properties were investigated in tangsuyuk batter containing different amounts of ingredients, such as wheat flour, corn starch, sodium bicarbonate, alum and water. For the response surface methodology (RSM) central composite design was used to determine the optimal ingredient ratios for viscosity, color properties(lightness, redness, yellowness, color differences) and cutting forces. There were significant differences(p<0.05) between the different batter mixtures. The lightness(L) of batter was in proportion to the increased amount of wheat flour and corn starch. Higher redness was recorded with increasing corn starch. Higher yellowness was observed with increasing wheat flour and sodium bicarbonate. Color differences were higher with increasing wheat flour, corn starch, and/or alum and decreasing water. Cutting forces were linearly increased with increasing sodium bicarbonate. From these results, it is possible to monitor the effects of ingredients on physical properties of tangsuyuk batter, and to predict their optimal ratios.

This study investigated the effects of tangsuyuk batter ingredients on sensory. The optimal condition was evaluated by using RSM(response surface methodology). Five ingredients(wheat flour, corn starch, sodium bicarbonate, alum, water) were used as independent variables, coding 36 experimental trials. The resulting sensory scores(flavor, fracture, color, overall acceptability) were used as dependent variables. Each dependent variable showed significant differences(p<0.05). When the amount of sodium bicarbonate was increased, the sensory scores for flavor and fracture also increased. Sensory scores for color also increased when the amount of sodium bicarbonate was increased and the amount of alum decreased. Overall acceptability scored higher when the amount of sodium bicarbonate was increased. This is therefore indicates that sodium bicarbonate is likely a very important ingredient in the batter. The effects of each ingredient on sensory were thus investigated. The optimum ratios of wheat flour, corn starch, sodium bicarbonate, alum and water were predicted to be 27.55%, 19.34%, 0.27%, 0.19% and 52.65% respectively.

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.

High-ratio cakes made from the formulas with more sugar (140% based on flour weight) than flour have come to be preferred recently. To produced good light cake structure, cake batter must retain the many finely divided gas bubbles formed during mixing . Thermal setting of cake structure is mainly caused by starch gelatinization . The formula controls the temperature at which the cake batter changes from a fluid to a solid. Especially, the relatively large amount of sugar used in the formula delays gelatinization, so that air bubbles can be properly expanded by carbon dioxide gas and water vapor before the cake sets. To get a non collapsing high ratio cake structure after baking , the proper degree of gelatinization of the starch granule, the control of gelatinization temperature, and sufficient gel strength ar all important. The role of ingredients (flour , sugar, proteins, chemical leavening agents, water shortening , and emulsifiers) is reviewed with relation to the formation of satisfactory cake structure.

To obtain basic data for the utilization of saltwort (Salicornia herbacea L.) as a functional ingredient in steamed foam cake, the optimum component ratios for major raw ingredients (saltwort, salt, and wheat flour) as independent variables that affect the product quality were scientifically determined using RSM (response surface methodology) technique. A three-factor and five-level rotational central composite design was used for treatment arrangement. The complete design consisted of 16 experimental points. The three independent variables selected for the RSM experiment were amounts of saltwort (X$_1$, 5${\sim}$25 g), salt (X$_2$, 0${\sim}$10 g), and wheat flour (X$_3$, 470${\sim}$530 g). The optimum responses in specific gravity of the batter and volume, color, texture, and sensory evaluation result of the cake were obtained. The specific gravity and viscosity of the batter at p<0.01 was verified from the regression curve. The characteristic of the batter was influenced by all independent variables, but was extremely dependent on the amount of saltwort ordinary points of the surface responses from the batter formed the minimum points for specific gravities of the batter while viscosities of the batter appeared with the saddle points. Analysis of the response indicated that the amount of saltwort was the most influential factor over the physical properties of the cake, among the dependent variables. Ordinary points of the surface responses from the cake formed the maximum points for loaf volume, hardness gumminess, and chewiness, while Hunter colorimetric parameters appeared with the saddle points. The result indicated that level of the saltwort deviating more or less from the optimal amount decreased the volume and increased the specific gravity with less tender product. Ordinary points of the surface responses of the sensory evaluation scores from the cake formed the maximum points for appearance, flavor, softness, and overall acceptability, while color values appeared with the saddle points. The result also indicated that the level of the saltwort deviating more or less from the optimal amount reduced the preference for the product. Integration of the optimum responses common to all dependent variables that overlapped all the contour maps finally indicated that the combination of 8.3${\sim}$13.8 g saltwort, 2.5${\sim}$6.6 g salt, and 486.5${\sim}$511.5 g wheat flour under the selected preparation recipe optimized the physical and sensory properties in the teamed foam cakes. Practical preparation of the product with median amounts of the ingredients, i.e., 11.0 g saltwort, 4.6 g salt, and 499.0 g wheat flour resulted in similar qualities to the predicted responses. In conclusion, these study results indicated that preparation of steamed foam cake with added saltwort ingredient could potentially produce a more nutritious product with less salt. Further research is required to acquire the optimum levels for sub-ingredients to improve the product quality.

We attempted to develop a seafood menu by applying the most preferred recipes to the most disliked seafood menus in order to improve elementary schoolers' seafood menu preferences and consumption levels. A survey was conducted on the attitudes of 106 fifth graders about nine cooking methods and 37 school seafood menus served in the past 2 years. The deep-frying method was the most preferred by both boys and girls. The next preferred methods by boys were grilling and batter-frying while those by girls were stir-frying and batter-frying. The most disliked menus were cold jellyfish salad, mussel soup, dried-pollack soup, and sea-snail salad in that order. Mussel soup, dried-pollack soup, and seasnails salad ranked as the least preferred menu as well. Finally, standardized recipes for mussel croquette, dried-pollack Gangjeong, and batter-fried seasnails were developed. Consumption ratios of mussel croquette (85.94%), dried-pollack Gangjeong (79.55%), and batter-fried seasnails (75.5%) were significantly improved compared to the original menu (p<0.001). For mussel croquette, satisfaction scores for serving size, appearance, flavor, texture, and taste were significantly higher, and intakes of protein, phosphorus, iron, potassium, vitamin A, vitamin B1, vitamin B2, niacin, and vitamin C were significantly improved, as compared with mussel soup (p<0.001). Dried-pollack Gangjeong, texture and taste scores were significantly improved compared to dried-pollack soup. For batter-fried seasnails, protein, phosphorus, and iron intake levels and taste score were significantly improved compared to seasnail salad. Findings of the study suggest that a combination of disliked seafood ingredients and preferred recipes may be helpful in improving elementary school foodservice by increasing menu preference and consumption ratio.

The purpose of this study was to survey the various kinds of cooked beef products focusing on "chim" (a steamed beef recipes) through historical literatures written from 1945 to 1997 in Korea. " Chim" was recorded 96 times in the references and could be classified into 3 groups based on major ingredients suchas the cud pouch, liver , spine , tongue, fleshes, beef, rib and tail, an could be classified into 14 groups based on minor ingredients such as vegetables fried beef in egg batter. tomatoes, callion and rice cake. Among the seventeen cooked recipe of " chim", "kalbi chim(rib) " was recorded most frequently and "satae chim(shank)" was the next. Though "yang chim(the cud pouch), salkogi chim(fleshes), sokalbi chim(rib) and sokori chim (tail) " has been sued until present day, salkogi chim subdivided into satae chim, udun chim, nubianisam chim, sosim chim in the middle twenty centuries. Ribs was most popular ingredient among the major ingredients such as the cud pouch, liver, spine, tongue, tail, fleshes. Decorating ingredients such as sukgi mushroom, minarichodae, pyoko mushroom, gingkonut also come into use subingredients or decorating ingredient in the 1990.nto use subingredients or decorating ingredient in the 1990.

In this study, frying mix was prepared containing 0.5, 1.0, 1.5 or 2.0% brown rice fiber(BRF). The samples along with a control were then compared regarding their quality characteristics, including pasting properties, spreadability, pick-up ratio, color, textural characteristics, moisture and oil contents, and sensory qualities, all to determine the optimal ratio of BRF. For the pasting properties of frying mix, the control group was evidenced by a significantly higher peak viscosity, through viscosity, and final viscosity than that observed in the BRF samples. Breakdown was the highest at the 1.0% addition level, and time to peak viscosity and pasting temperature were maximal with the 0.5% addition. There was no significant difference in setback among the experiments. Spreadability and pick-up ratio of frying batter were not significantly different among the samples. As the BRF content increased, the lightness, greenness decreased, whereas yellowness increased. The BRF samples presented significantly higher hardness of fried batter than the control group and there was no significant difference in crispiness among the samples. Moisture content of fried sweet potato decreased with increasing BRF and oil content was the maximum on the control group. In the sensory evaluation, appearance, color, flavor, savory taste, yellowishness, coating thickness, off-flavor, and oiliness were not significantly different among the fried sweet potato samples. Bindingness, crispiness, and chewiness were highest in the control samples but minimal at a addition level of 2.0%. The control group evidenced significantly higher overall acceptability than were observed in the BRF samples. In conclusion, the results demonstrated that 0.5~1.0% BRF may prove quite useful as a additive for frying mix in the preparation of fried sweet potato and may provide favorable textural and functional properties.
