This study was conducted to establish the standard method for the contents of biotin in milk formulas. To optimize the method, we compared several conditions for liquid extraction, purification and instrumental measurement using spiked samples and certified reference material (NIST SRM 1849a) as test materials. LC-MS/MS method for biotin was established using $C_{18}$ column and binary gradient 0.1% formic acid/acetonitrile, 0.1% formic acid/water mobile phase is applied for biotin. Product-ion traces at m/z 245.1 ${\rightarrow}$ 227.1, 166.1 are used for quantitative analysis of biotin. The linearity was over $R^2=0.999$ in range of $5{\sim}60{\mu}g/L$. For purification, chloroform was used as a solvent for eliminating lipids in milk formula. The linearity was over 0.999 in range of 5~60 ng/mL. The detection limit and quantification limit were 0.10, 0.31 ng/mL. The accuracy and precision of LC-MS/MS method using CRM were 103%, 2.5% respectively. Optimized methods were applied in sample analysis to verify the reliability. All the tested milk formulas were acceptable contents of biotin compared with component specification and standards for nutrition labeling. The standard operating procedures were prepared for biotin to provide experimental information and to strengthen the management of nutrient in milk formula.

In this study, we sought to investigate the various characteristics of Salmonella spp. isolated from raw chicken meats available in Korean markets. The data collected, such as food source of isolation, sampling information, serotype, virulence, and genetic profile including sequence type, were registered in the database for further comparative analysis of the strains isolated from the traceback investigation samples. To characterize serotype, virulence and gene sequences, we examined 113 domestically distributed chicken meat samples for contamination with Salmonella spp. Phylogenetic analysis was conducted on 24 strains (21.2%) of Salmonella isolated from 113 commercially available chicken meats and by-products, using pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST). Serotyping of the isolated Salmonella spp. revealed S. Enteritidis in 11 strains (45.8%), S. Virchow in 6 strains (25%), S. Montevideo in 2 strains (8.3%), S. Bsilla in 2 strains (8.3%), S. Bareilly in 1 strain (4.2%), S. Dessau in 1 strain (4.2%), and S. Albany in 1 strain (4.2%). The genetic correlation indicated that 24 isolated strains were classified into 18 clusters with a genetic similarity of 64.4-100% between them. Eleven isolated S. Enteritidis strains were classified into 9 genotypes with a sequence identity of 74.4%, whereas the most distantly related S. Virchow was divided into five genotypes with 85.9% identity. Here, the MLST analysis indicated that the major Sequence Type (ST) of the Salmonella spp. isolated from domestic chicken sold in Chungcheong Province belongs to the ST 11 and 16, which differs from the genotype of Salmonella isolated from imported chicken. The differential sequence characteristics can be a genetic marker for identifying causative bacteria for epidemiological investigations of food poisoning.

The purpose of this study was to explore the moderating effect of food safety scandals on the relationship between food company's Corporate Social Responsibility(CSR) engagement at different levels and brand image in the Chinese dairy company context. In addition, this study also examined the mediating effect of brand image on CSR engagement and consumer loyalty. The study adopted a $2{\times}2$ between-subjects experimental design using scenarios. Four scenarios provided a mixed combination of yes or no cases for food safety scandal, and high or low cases for a dairy company's CSR engagement. In this study, survey was used to collect data from Chinese consumers. Of these, 377 valid data were collected from a sample of average Chinese consumers over the age of 20, collected through the internet. The results show that CSR engagement at different levels has a significant effect on brand image and food safety scandal has a significant moderating effect on the relationship between the two. This study expanded the previous study on the sensitivity of consumers to CSR activities in eastern China. At the same time, according to the results of the study, different CSR engagement of food enterprises does have a significant impact on brand image and consumer loyalty. In particular, high CSR engagement reduces negative impact on brand image through the moderating effect of food safety scandals. Therefore, for food business managers, actively participate in CSR activities, and actively enhance the engagement has a significant influence on the management of brand image.

This study was conducted to investigate the effective educational and promotional strategies for the Special Act on the Safety Management of Children's Dietary Life on the basis of the survey conducted on parents. First of all, its result showed that most parents are well aware of the main contents of the law. They answered that, when choosing safe favorite food for children, the most important part is the article "Regulations on the standards for children's favorite food should be reinforced." As for the index of safety management for children's dietary life, most respondents think safety the most important; housewives and nuclear family members choose safety (p<.01), while large family members do nutrition. For the question asking how they get the information on safety management for children's dietary life, most of them answered that they generally use mass media, family and friends as a reference. Those with high income usually get the information from special books, those between 30s and 50 from mass media, and those with college graduates from civil social groups (p<.05). In case of taking the safety education programs for children's dietary life, they told that the most necessary information is concerned with hygienic dietary life and nutrition labeling on processed food; housewives are interested in the latter, while working people in the former (p<.05). As a method of informing parents of the Special Act on the Safety Management of Children's Dietary Life, mass media such as TV and radio, and school education are suggested in this survey. Therefore, this study proposes that mass media be considered as the most effective way of promoting the Special Act on the Safety Management of Children's Dietary Life and getting information concerning the law.

Recent trends of global food production, processing, distribution and preparation under free trade circumstance are creating an increase in common' concerns about food safety. It is important that farmers improve agricultural products/food safety for satisfying consumer needs and health. Cognizant to the situation, this study was conducted to analyze how the Producers gather information, and determine their awareness about agricultural Products safety using a safety Questionnaire. The Questionnaire was given to 500 farmers who cultivate rice, fruit trees, vegetables, and other crops from September through October 2005. More than half of the producers felt concerns about the agricultural products/foods safety. Uneasiness of the producers was higher amongst those who were younger and earned a higher income. Pesticides and zoonosis (BSE AI, etc.) emerged as the main risk factors causing concerns among the greatest number of producers. Producers had a positive opinion of the effects and perception of food safety, but no opinion of the activity of government. The producers showed a high level of understanding of the Country of Origin Labeling System (88.2%), the quality certification system of agricultural and livestock products (71.9%), and the raising system of environment-friendly agriculture (72.7%). However, their level of understanding of the GAP (59.3%) and the Traceability System (22.8%) was still low. To effectively implement these policies, awareness of producers who are the beneficiaries of the above policies has to be enhanced. Therefore, the safety information should be provided at a more appropriate time and should be easier to understand.
