  • 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.

  • The purpose of this study was to investigate the levels of knowledge and behavior towards food hygiene among child consumers, examine the factors influencing them, and analyze the causal relationship between them. The data were collected from 521 elementary school students in Youngnam area by a self-administered questionnaire. Frequencies, Pearson's correlation analysis, multiple regression analyses, and path analysis were conducted by SPSS Windows. The results from this study were as follows. First, the level of knowledge towards food hygiene was not particularly high, and the level of behavior was somewhat more than the average. Second, the factors influencing the level of knowledge towards food hygiene were school record (upper and middle), and concerns about food hygiene. In addition, concerns about food hygiene, the frequency of food hygiene education in the family, and the level of knowledge towards food hygiene had an effect on the level of behavior towards food hygiene. Third, in the analysis of the causal relationship between the knowledge and behavior towards food hygiene, school record indirectly influenced the behavior towards food hygiene, and the frequency of food hygiene education in the family directly affected the behavior towards food hygiene. On the other hand, concerns about food hygiene had direct and indirect influence on the behavior towards food hygiene. In addition, the knowledge towards food hygiene showed a direct effect on the behavior towards food hygiene. These results imply that knowledge towards food hygiene is a very important factor to improve the children's behavior towards food hygiene and that parents' concerns and guidance for children are needed.

  • Objectives: This study was carried out to provide safe seafood to the public through simultaneous analysis rapid inspections for residual veterinary drugs in 150 fishery products in 2016. Methods: Quinolones (9), Sulfonamides (14), Penicillins (2), Cephalosporins (3), Tetracyclines (4), Macrolides (4), Lincosamides (2), Pleuromutilin (1), Phenicols (4), benzylpyrimidines (2), Others (1) Malachite green (2), and Melamine (1) were analyzed for 49 species using by HPLC and HPLC-MSMS. Results: There were six unsuitable samples, five among fish and one for crustaceans. Within the standard detection were five fish. The antibiotics found were Quinolones (50%), Tetracyclines (33%) and Penicillins (17%). Conclusions: As a result of the experiment, there were six unsuitable samples, five for fish and one for crustaceans. The most prevalent antibiotics were Quinolones. The quinolone antibiotics are highly persistent in fish tissues, so they require more time than the withdrawal period for other common veterinary drugs. Careful attention is required when they are used in fish farms.

  • Purpose - This study investigated the main variables of consumer food choice motive and how they affect attitude and purchase intention toward organic foods. The study involved a multiple regression analysis to verify the influence of food choice motive on attitude toward organic food. Research Design, Data, and Methodology - Data was collected through surveys of 280 students and ordinary citizens in Seoul and the Gyeonggi region, using sampling. A multiple regression analysis was performed to confirm the impact of food choice motive on attitude toward organic food, and a regression analysis was performed to identify the impact of attitude toward organic food on purchase intention. Results - Health and environment, among food choice motives, had significant positive influence on attitude toward organic food, whereas convenience, price, and familiarity had no impact. Attitude toward organic food had significant positive influence on organic food purchase intention. Conclusions - As this study identified the impact of organic food choice motive, it may provide baseline data for marketing strategies, to understand consumer attitude toward organic food and purchase intention, and to satisfy consumer needs.

  • Rapid development of next-generation sequencing (NGS) technology is available to study microbes in genomic level. This NGS has been widely used in DNA/RNA sequencing for genome sequencing, metagenomics, and transcriptomics. The food microbiology area could be categorized into three groups. Food microbes including probiotics and food-borne pathogens are studied in genomic level using NGS for microbial genomics. While food fermentation or food spoilage are more complicated, their genomic study needs to be done with metagenomics using NGS for compositional analysis. Furthermore, because microbial response in food environments are also important to understand their roles in food fermentation or spoilage, pattern analysis of RNA expression in the specific food microbe is conducted using RNA-Seq. These microbial genomics, metagenomics, and transcriptomics for food fermentation and spoilage would extend our knowledge on effective utilization of fermenting bacteria for health promotion as well as efficient control of food-borne pathogens for food safety.

  • This study examined the levels of risk perception of food risk elements by adopting a psychometric paradigm and analyzed factors affecting concerns about food risk elements to obtain basic materials for food safety policy. The data were collected from 296 housewives in Daegu, Korea, by a self-administered questionnaire. Frequency distributions, Pearson's correlation coefficient analysis, factor analysis, Cronbach's ${alpha}$, and multiple regression analyses were conducted by SPSS 21.0. The mean level of concern for food safety was 3.75/5.00 points, and the mean percentage of correct answers about heavy metal contamination was highest among food risk elements. The respondents perceived radioactive contaminated foods, GM foods, and endocrine disruptors as a new, delayed, scientifically unknown, involuntary, serious, and uncontrollable risk in risk perception. According to the result of factor analysis for risk perception, two factors such as non-controllability and dread were categorized. In the risk perception map, radioactive contaminated foods and GM foods were considered as an uncontrollable and dreaded risk, heavy metal contamination, endocrine disruptors, and pesticide residues as a controllable and dreaded risk, and foodborne illness and food additives as a controllable and less dreaded risk. On the other hand, the levels of concerns about food risk elements were higher in order of radioactive contaminated foods, GM foods, and endocrine disruptors. The results of multiple regression analysis showed that age, concern for food safety, percentage of correct answers about food risk elements, non-controllability, and dread influenced the concerns about food risk elements. These results imply that food safety policies should consider differences in consumer's risk perception of food risk elements.
