This study aims to analyze importance and performance factors on the quality of wellbeing fusion menu of fusion restaurants to provide helpful information for building up a detailed marketing strategy and present considerations for sales increase and more efficient business results. Importance on menu quality scored a higher level than performance on the whole in fusion restaurants. Notably, in regard to attributes of menu quality, it was found that respondents put higher stress on 'taste of food', 'sanitary of food', 'cleanliness of vessels', 'quality of menu' and 'freshness of food' than anything else. Wellbeing fusion menu which has an high intake frequency rate includes 'green vegetable noodles with black bean sauce', 'sweet pumpkin salad', 'salmon salad', and 'shrimp vegetable gratin' in that order. On the other hand, the intake frequencies of 'ovened green perilla gratin', 'pomegranate dressing tofu', 'bacon roll with glutinous rice powder', and 'pomegranate dressing bacon' were rated very low. In terms of the IPA analysis on wellbeing fusion menu quality, it was important to continuously maintain 'taste of food', 'sanitary of food', 'cleanliness of vessels', 'freshness of food', 'quality of menu', 'diet menu(low fat, low calories)', 'vegetable menu', 'nutrition of food', 'variety of menu' etc. Such items as 'price', 'distinction with existing food', and 'environment-friendly organic agriculture food material' are in need of intensive care and operation.

Physicochemical characteristics of traditional kochujang fermented for 6 months and commercial kochujang were compared. Tested kochujang included 18 kinds of Sunchang kochujang prepared with glutinous rice, 10 kinds of Boeun kochujang prepared with barley and 17 kinds of Sachun kochujang prepared with wheat, and 10 kinds of commercial kochujang. Major free sugar was found to be glucose both in traditional and commercial kochujang. Fructose, maltose, and sucrose were also detected in small amounts. The contents of free sugars in traditional kochujang was approximately one fourth of those presented in commercial kochujang. Commercial kochujang showed the highest level of total free amino acids followed in decreasing order by Sachun, Sunchang, and Boeun kochujang. The most abundant free amino acid was serine in Sunchang kochujang and aspartic acid both in Boeun and Sachun kochujang. On the other hand, glutamic acid was the most abundant amino acid in commercial kochujang. Volatile organic acids in various kochujang were determined and acetic, propionic, butyric, and 3-methyl butanoic acids were found in traditional kochujang. However, 3-methyl butanoic arid was not found in commercial kochujang. The most abundant volatile acid was acetic acid in both tradtional and commercial kochujang. Analysis of non-volatile organic acids showed that large amounts of lactic, oxalic, and succinic acids were found in traditional and commercial kochujang. In addition to these, small amounts of itaconic, malic, malonic, and pyroglutamic acids were found in commercial kochujang.

Quality characteristics of 3 kinds of traditional kochujang were investigated during 6 months of fermentation in order to obtain information for the industrial production of traditional kochujarg. Tested kochujang included Sunchang kochujang prepared with glutinous rice, Boeun kochujang prepared with barley, and Sachun kochujang prepared with wheat. The reducing sugar contents of Sunchang, Boeun, and Sachun kochujang increased up to 30, 90, and 150 days of fermentation, respectively, and then decreased thereafter. Ethanol contents of traditional kochujang increased up to $0.4{\sim}1.2%\;at\;120{\sim}150$ days of fermentation and decreased thereafter. Amino nitrogen content of Sunchang kochujang showed a slight increase during fermentation, however, those of Boeun and Sachun kochujang showed a rapid increase up to 150 days of fermentation. Ammoniacal nitrogen content of 100 g kochujang increased up to $50{\sim}75mg$ at 60 days of fermentation and leveled off thereafter. Capsaicin and capsanthin contents of 100 g kochujang were $15{\sim}18mg\;and\;60{\sim}180mg$ before fermentation and decreased to $12{\sim}14mg$ and $50{\sim}120mg$ at 180 days of fermentation, respectively.

Quality characteristics of griddled miljeonbyeong containing vegetable juice were assessed by conducting sensory tests and measuring texture and color. When varying amounts of carrot/or spinach juice was added to miljeonbyeong, the sensory preferences of appearance and texture were higher in miljeonbyeong containing a small amount of carrot and spinach vegetable juice, and the preferences of smell and taste were higher in miljeonbyeong containing a large amount of carrot and spinach juice. Overall, preference was highest in miljeonbyeong supplemented with 30 g carrot juice and 10 g spinach juice. Overall preference correlated significantly with appearance (r=0.44) and texture (r=0.47). In miljeonbyeong containing vegetable juice, tensile strength decreased significantly with increasing amounts of carrot juice (34.98~30.82) or spinach juice (40.84~37.07). In all miljeonbyeong samples, tensile strength increased slightly in 1 hour but rapidly increased after 2 hours. Lightness progressively decreased. A-value increased (3.46~9.63) and b-value increased with increasing amounts of vegetable juice added. No difference in the b-value increase was evident between carrot juice (15.19~26.43) and spinach juice(18.19~24.40). Tensile strength was markedly lower in miljeonbyeong amended with carrot juice (34.98~30.82g) or spinach juice (39.05~32.67 g), which contained fat-soluble pigment, as compared with vegetable-free miljeonbyeong (44.81 g), but the addition of beet juice (45.30~44.78 g) containing water-soluble pigment did not lower the tensile strength of miljeonbyeong compared to vegetable juice. In order to improve the texture of miljeonbyeong containing vegetable juice, tensile strength was measured in miljeonbyeong prepared with 30 g carrot juice or 10 g of spinach juice, which produced the highest sensory test scores, and additionally amended with potato starch, corn starch, glutinous rice flour, strong flour or yam powder with a consequent reduction in the content of wheat flour. Improvement was noted in carrot juice-containing samples prepared with 6 g corn starch, 15 g potato starch and 15 g hard wheat flour, and in spinach juice-containing samples prepared with 6 g corn starch, 6 g potato starch, 6 g hard wheat flour and 15 g dried yam powder.

The purpose of this study was to develop a standardized recipe of Hwajeun(glutinous rice pancake with flower) by evaluating various methods appeared in the literature. For this purpose, the effects of the volume and temperature of water used to make dough on the sensory and rheological characteristics of Hwajeun were investigated. This experiment consisted of sensory evaluation in acceptance and intensity(appearance, color, moistness, softness, chewiness, adhesiveness, taste and overall preference), objective evaluation by using texture analyser, color difference meter and measurement of water content and oil absorption ratio. The loss ratio of moisture contents between dough and cooked Hwajeun were 2.4 ~2.8%, and the oil absorption ratio of Hwajeun made by 2$0^{\circ}C$water for kneading increased in proportion to the increment of water added(p＜0.01). In terms of color, b value of Hwajeun made by 104$^{\circ}C$ salted water for kneading showed higher value compared to the others. In the two bite compression test, adhesiveness, springiness, gumminess and chewiness of Hwajeun made by 2$0^{\circ}C$ water(36%) for kneading showed significantly(p＜0.05) high value among the samples. As a result of sensory evaluation, Hwajeun made with 27% of 104$^{\circ}C$ salted water for kneading was most preferred in softness, chewiness, taste and overall preference

In this study, kim (dried laver) bugak ("KB"), Aster yomena bugak ("SB"), and namul (vegetables)-kim bugak (combination of Aster yomena and kim) ("NB") were prepared and their quality characteristics were investigated. NB was made by slicing Aster yomena, seasoning it with perilla seeds, attaching it to kim and applying glutinous rice paste, followed by freeze-drying. SB had a higher oil absorption rate than KB, reflecting the high oil absorption rate of namul (here, Aster yomena). DPPH radical scavenging activity was highest for SB; whereas, NB had higher DPPH radical scavenging activity than KB, indicative of the higher antioxidant capacity of namul, as compared to kim. With longer storage period, moisture content tended to be increased, while maximum load, yield stress and hardness tended to be decreased. Overall preference was in the order of NB>KB>SB, without statistical significance. Acid value and peroxide value of NB, stored at $25^{\circ}C$ for 40 days, tended to be increased gradually but did not meet the criteria for rancidity. Therefore, NB could be stored at $<25^{\circ}C$ for > 40 days. Furthermore, it would be possible to make functional bugak using a variety of namul, as well as Aster yomena.

Changes in microflora and enzyme activities of 3 kinds of traditional kochujang were investigated during 6 months of fermentation. Tested kochujang included Sunchang kochujang prepared with glutinous rice, Boeun kochujang prepared with barley and Sachun kochujang prepared with wheat. The pH in Sunchang and Sachun kochujang showed a slighlt decrese during fermentation. In contrast, pH of Boeun kochujang decreased rapidly up to 90 days of fermentation and then leveled off thereafter. The final pH values of Sunchang, Boeun and Sachun kochujang were 4.7, 4.0, and 4.6, respectively. The viable cell counts of aerobic bacteria in Sunchang and Sachun kochujang did not show remarkable changes during fermentation, however, those in Boeun kochujang showed a rapid increase up to 60 days of fermentation and stabilized. On the other hand, the viable cell counts of anaerobic bacteria decreased after 120 days of fermentation. Yeasts were found in different traditional kochujang at different time during the first 60 days of fermentation. It was found that ${\alpha}-$, ${\beta}-$, and glucoamylase activities of Sachun kochujang were higher than those of Sunchang and Boeun kochujang during fermentation. Acidic and neutral proteases showed the highest activity during $30{\sim}60\;days$ and $60{\sim}90\;days$ of fermentation, respectively. Sunchang kochujang showed the highest activity of acidic protease followed in decreasing order by Sachun and Boeun kochujang. On the other hand, Boeun kochujang showed the highest activity of acidic protease followed in decreasing order by Sachun and Sunchang kochujang.

Oral health can influence on diverse food intake, and food intake affect oral health related quality of life. The aim of this study was to select key foods to be able to represent oral health related quality of life in Korea. We used the data of 503 Korean older persons to participate in the oral health promotion programme in 2009. The low consumption or low intake foods with criteria in 2012 National Nutrition Statistics were eliminated among 30 foods of food intake ability (FIA) at first. Decision tree model, correlation analysis, factor analysis, and internal reliablity test were used for oral health related quailty of life (OHRQoL) key food selection. We selected 13 foods-hard persimmon, dried peanut, pickled radish, caramel, rib of pork, glutinous rice cake, cabbage kimchi, apple, yellow melon, boiled chicken meat, boiled fish, mandarin, noodles as OHRQoL Key Foods 13. Thirty foods of FIA and OHRQoL Key Foods 13 displayed the same pattern of variation among sociodemographic groups. In a regression model, both of 30 foods of FIA and OHRQoL Key Foods 13 influenced on oral health impact profile-14. The findings suggest that OHRQoL Key Foods 13 have good reliability and validity and be able to use in oral health survey.
