The purpose of this study was to investigate the quality characteristics of sponge cake with various amounts of mulberry leaf powder in place of flour. The specific gravity of kneading was maintained at the different amounts of added mulberry leaf powder, which increased at ratios of 5, 10, 15, and 20 percent. The crumb decreased greatly when flour rather than mulberry leaf powder was used. As the amount of mulberry powder increased, red and yellow color decreased in both the crumb and crust. The volume and symmetry indices of the sponge cake slightly decreased when the amount of mulberry powder increased. However, uniformity was not significantly different between the samples. The specific volume of the cake decreased when the amount of the mulberry leaf powder increased. In addition, mulberry leaf powder increased the degrees of hardness and gumminess of cake, but did not show any differences for the cohesiveness and springiness of the cake texture. In the consumer acceptability test, the most favorable taste and odor were attained at the 10 percent level of mulberry leaf powder.

This study was conducted to monitor residues of 10 veterinary drugs in food products. Various veterinary drugs were examined including enrofloxacin, ciprofloxacin, norfloxacin, oxolinic acid, amoxicillin, ampicillin, oxytetracycline, tetracycline, chlortetracycline, and doxycycline in beef, pork, egg, chicken, eel, flatfish, and rockfish obtained from 6 different regions (Seoul, Incheon, Daejeon, Gwangju, Daegu, Busan). Residues were detected in 21 (6.5%) samples out of 321 samples. In particular, 2 (1.0%) livestock samples had detected residues among 203 products, and 19 (16.1%) aquaculture samples had residues detected among 118 products. The most frequently detected drug residues in aquaculture products were oxytetracycline and amoxicillin, but the levels were mostly below the MRL (Maximum Residue Limit). In only one flatfish sample, amoxicillin was found at a level higher than the MRL (0.05 mg/kg). In livestock products, residues of most veterinary drugs were not detected. But enrofloxacin was detected in 2 chicken (Korean name: Ogolgae) samples at a higher level than the MRL (0.1 mg/kg as the sum of ciprofloxacin).

The objectives of this study are, first to define the concept of restaurant total coordination and establish its components as a design strategy for planning and managing all elements comprising a restaurant, and second, to survey the total coordination of Japanese restaurants in foreign countries and examine how traditionality, which is an element for globalizing Japanese restaurants, is expressed. This study was conducted through literature review for defining the concept of restaurant total coordination and extracting its components and a field survey for analyzing the current state of restaurant total coordination and traditionality expression methods. The results of this study are as follows. First, Japanese restaurants categorized into Type A with relatively high traditionality expression(3.3 or higher) were 25% of the surveyed restaurants. These restaurants showed the traditional characteristics of Japanese style as they are without contemporary adaptation for all components of restaurant. Second, 41.7% of the restaurants were categorized into Type B with traditionality expression between 1.7 and 3.3. They were mostly popular casual restaurants at which people can enjoy Japanese food comfortably. In visual and spatial design elements, traditional and contemporary styles appeared in the equal percentage, and decoration, table setting and food design were styled according to Japanese traditions. Third, 4 cases(33.3%) were categorized into Type C with traditionality expression below 1.7. Because they were fine dining restaurants that sold high priced dishes, formality and consistency were also high. Through all design elements including visual, spatial, table setting and food design elements, elegant and simple contemporary images were dominant. The results of this study will be used as basic materials to establish the concept of total coordination that views the visual, spatial, table setting and food design elements comprising a restaurant, which were approached separately in previous studies on restaurants, together from the viewpoint of integrative deigns, and to make design strategies for globalizing Korean restaurants based on Japanese restaurant cases.

This study examined customers from restaurants in hotels in the Busan and Gyeongnam region, South Korea, to confirm if dinging area decoration has any indirect effect on behavioral intention via customer emotional response and the mediating effects of customer emotional response in order to provide the basic materials of marketing strategies for continued customer visit to the hotel restaurants. The implications of the study are summarized as follows: First, if restaurant space is designed in consideration of gustatory, visual, auditory, tactile, and olfactory aspects, it becomes a reason for customers to re-purchase and spread good words of mouth. Second, restaurant food space should be designed to make customers pleasant and exciting. Third, the design of food restaurant design that induces customer emotional responses elevates customer re-purchase and intention to deliver words of mouth.

This study aims to investigate the quality characteristics of breads with the addition of sweet pumpkin powder. Farinogram showed that the absorption rate of the dough decreased, the development time and stability became shortened, and the degree of attenuation tended to be grown along with increasing the amount of pumpkin powder. From the amylogram, it was found that the gelatinization starting temperature and the maximum viscosity of pumpkin powder added dough seemed to be decreased as the amount of pumpkin powder was increased. Extensogram showed that there was a decrease in the degree of extension of the dough added with increasing the amount of pumpkin powder, while an increase in the degree of resistance and resistance/extensibility. The lightness (L value) and redness (a value) of bread was found to be decreased with increasing the amount of pumpkin powder, while the yellowness (b value) increased. In terms of the dough texture, for which the hardness, cohesiveness and gumminess of the dough were measured, there were no significant differences between groups, while the dough added with 8.0% pumpkin powder showed a significant decrease in the elasticity. The results of sensory evaluation showed that the highest score of color (p<0.05) and taste (p<0.05) were obtained from the bread added with 6.0% and 8.0% pumpkin powder, while the highest score of texture in control and 3.0% pumpkin bread. In addition, the highest score of flavor (p<0.05) and overall acceptance (p<0.05) were observed in bread added with 6.0% pumpkin powder. Upon the results of this study, it was assumed that the development of food products using pumpkin are prospective in response to health-oriented consumers.

The influencing factor in drying characteristics of fluidized bed drying with different drying conditions for husked barley were carried out. This fluidized drying mechanism of husked barley was consisted of consecutive two falling rate parts, first falling rate period and second falling rate period without showing constant rate period. The drying rate constant was increased with decreasing charged amount and relative humidity and increasing air temperature and air velocity. Since the drying rate constant expressed by Arrhenius type equation in the falling rate period showed good linearity, the falling rate period was condsidered as the controlling step. The activation energy of first falling step was 1,100 cal/gmol, while for second falling step the values showed 1,600 cal/gmol.

In Korean, nine tar colors are permitted in foods. This study assessed these compounds in the favorite food items of children found near elementary schools. A total of 439 items categorized under six food types were included in the analysis. The most frequently detected tar colors were tartrazine (Y4), Brilliant Blue FCF (Y5), Allura Red, and Sunset Yellow FCF, respectively. One or a mixture of two tar colors were commonly found in products such as gums, ice bars, soft drinks, and cereals. However, most often, combinations of two or three tar colors were detected. The levels of tar colors in candies, chocolates, gums, ice bars, cereals, and soft drinks were 0.11-1169.58 mg/kg, 0.73-468.02 mg/kg, 0.10-602.46 mg/kg, 0.25-162.32 mg/kg, 0.11-753.68 mg/kg, and 0.21-69.45 mg/kg, respectively. Tar color levels were higher in chocolates and gums than in soft drinks and ice bars. And Y4 and Y5 were detected at the highest levels. For ages 7-12, the total estimated daily intake (${\sum}EDI$) of each tar color ranged from 0.004 to 1.017 mg/day/person. These values were 0.02-5.98% of the FAO/WHO's acceptable daily intake (ADI).
