  • The purpose of this study was to investigate the influence of cooking wine's functions on food quality attributes. factor analysis, reliability analysis (Cronbach's $\alpha$), and multiple regression analysis were employed to analyze the data. The cooking wine functions were divided into 3 factors (expectation of utility, functionality, and quality enhancement). According to the multiple regression analysis of cooking wine factors to food quality, all factors had positive influences on food quality. Among the three factors, expectation of utility(=.556, p<0.001) had the most significant influence on food quality. And functionality (=.321, p<0.001) and quality enhancement(=.296, p<=0.001) also had significant effects in that order. further research should be conducted on cooking wine's utility aspects and their effects on food quality. Finally, we anticipate that the results of this study will be useful information for food-service companies.

  • It's not easy to detect the high quality and functional compounds for control quality of food materials. The electronic nose was an instrument, which comprised of an array of electronic chemical sensors with partial specificity and an appropriate pattern recognition system, capable of recognizing simple or complex odors. It can conduct fast analysis and provide simple and straightforward results and is best suited for quality control and process monitoring in the field of functional foods. Numbers of applications of an electronic nose in the functional food industry include discrimination of habitats for medicinal food materials, monitoring storage process, lipid oxidation, and quality control of food and/or processing with principal component analysis, neural network analysis and the electronic nose based on GC-SAW sensor. The electronic nose would be possibly useful for a wide variety of quality control in the functional food and plant cultivation when correlating traditional analytical instrumental data with sensory evaluation results or electronic nose data.

  • The purpose of this study was to determine the relationships among food quality, food awareness, customer satisfaction, and revisit intentions of Korean restaurants in Chinese University or College students in the Daegu and Gyeongbuk areas. A questionnaire developed from a literature review included a series of questions about the quality of Korean food, Korean food awareness, customer satisfaction, and revisit intentions. Analysis of the survey data was performed on 234 valid responses. Statistical analyses, including frequencies, factor analysis, reliability analysis and regression, were performed using the SPSS program. The results indicated that food quality perceived by Chinese students had a significant impact on customer satisfaction. On the contrary, food quality according to Korean food awareness by Chinese students did not have a significant impact on customer satisfaction. Further, customer satisfaction had a significant influence on revisit intentions, whereas customer satisfaction according to Korean food awareness did not have a significant effect. In conclusion, food quality is a significant factor in determining the success of the foodservice industry.

  • The purpose of this study was to investigate the effects of perceived price and servicescape on employee service quality, food and beverage quality, and customer value in Daegu Korean restaurants and to suggest methods for them to become the food mecca of Korea and the world. The samples for this study were customers of nine Korean restaurants in Daegu. A total of 368 questionnaires were analyzed with factor analysis, a reliability test, and a covariance structural analysis. The results showed that perceived price was positively related to employee service quality and food and beverage quality and that servicescape was positively related to employee service quality and food and beverage quality. However perceived price, servicescape, employee service quality, and food and beverage quality were not related to customer value. The reasons were that these factors did not influence perceived customer value in Daegu Korean restaurants. The Daegu municipal office should require these restaurants to develop distinguished employee service and food and beverage quality and conduct consistent marketing to Koreans and westerners, so that these restaurants can become the food mecca of Korea and the world.

  • This study was conducted to develop a construct model regarding the daily activities, emotional security provided by food, enjoyment of food, level of satisfaction with delivered food, and the quality of life of homebound seniors who benefitted from meal delivery programs. The data were analyzed by SAS 9.2 and the Structural Equation Model (SEM), which was created by Analysis of Moment Structure (AMOS) 5.0 packages. The reliability of the data was confirmed by an exploratory factor analysis and through a Cronbach's alpha coefficient, and the measurement model proved to be appropriate by a confirmatory factor analysis of the measurement model in conjunction with AMOS. The results of the correlations between all the variables showed significant positive correlations (P < 0.05). The path analysis demonstrated that the daily activities (P < 0.01) and the emotional security created by food (P < 0.05) had positive correlations with the foodservice satisfaction (P < 0.05), while the daily activities (P < 0.05), the sense of emotional security made by food (P < 0.05), and food enjoyment (P < 0.05) also presented significant positive correlations with the quality of life. However, the food service satisfaction was shown to directly, but not significantly, affect the quality of life. This revealed that the current meal delivery programs needed to be improved in several directions.

  • This study aimed at investigating any differences perceived between the contractor and the contractee based on an importance-performance analysis (IPA) of foodservice quality attributes. Questionnaires were distributed to 200 personnel concerned in the Busan, Ulsan and Kyungnam areas and a total of 134 valid responses were used for analysis. Of the 23 foodservice quality attributes, the factors of 'food quality', 'employee service', 'hygiene and safety', 'customer orientation' and 'operation quality' were induced from a scale purification process through the exploratory factor analysis. The level of importance (p<0.01) of the 'hygiene and safety' factor and 'employee service' factor was not found to be significantly different between the groups. In the level of performance, the factors of 'food service', 'employee service', 'customer orientation' and 'operation quality' were found to be perceived significantly lower than expected by the contractor group. In the importance level, 'food quality', 'employee service', 'hygiene and safety', 'customer orientation' and 'operation quality' were rated by the contractor as 4.03, 4.30, 4.27, 4.01 and 4.12 points, respectively. In contrast, in the performance level, perceived 'food quality', 'employee service', 'hygiene and safety', 'customer orientation' and 'operation quality' were evaluated as 3.57, 3.94, 4.06, 3.83 and 3.95 points, respectively.
