  • This review discusses the status, antimicrobial mechanisms, application, and regulation of natural preservatives in livestock food systems. Conventional preservatives are synthetic chemical substances including nitrates/nitrites, sulfites, sodium benzoate, propyl gallate, and potassium sorbate. The use of artificial preservatives is being reconsidered because of concerns relating to headache, allergies, and cancer. As the demand for biopreservation in food systems has increased, new natural antimicrobial compounds of various origins are being developed, including plant-derived products (polyphenolics, essential oils, plant antimicrobial peptides (pAMPs)), animal-derived products (lysozymes, lactoperoxidase, lactoferrin, ovotransferrin, antimicrobial peptide (AMP), chitosan and others), and microbial metabolites (nisin, natamycin, pullulan, ε-polylysine, organic acid, and others). These natural preservatives act by inhibiting microbial cell walls/membranes, DNA/RNA replication and transcription, protein synthesis, and metabolism. Natural preservatives have been recognized for their safety; however, these substances can influence color, smell, and toxicity in large amounts while being effective as a food preservative. Therefore, to evaluate the safety and toxicity of natural preservatives, various trials including combinations of other substances or different food preservation systems, and capsulation have been performed. Natamycin and nisin are currently the only natural preservatives being regulated, and other natural preservatives will have to be legally regulated before their widespread use.

  • BRIS has been established by the Ministry of Agriculture, Food and Rural Affairs since 2011 under Article 21 of the Act on the Preservation, Management and Utilization of Agricultural Life Resources. It is an information service that provides information related to agricultural life resources in connection with the Rural Development Administration, the Forest Service, and Korea Seed & Variety Service, Agricultural Resources and Agricultural and Livestock Quarantine Headquarters. The purpose of this study is to evaluate how the users assess the information system quality (information quality, system quality) for the current Bio Resource Information Service (BRIS). Ultimately, the structural equation modeling analyzes the causal relationship between each variable and how it responds to the user's continuous use intention. As a result, information quality among information system quality and information quality among system quality used as the main variables for the evaluation of BRIS were statistically positively influenced by users' perceived usefulness, while system quality It has been analyzed to have a positive effect on the sustained use intention. The user's continuous use intention is positively influenced by the information system quality and perceived usefulness at a statistically significant level. Especially, the perceived usefulness plays a role in mediating the user's continuous use intention.

  • This study examined the usage, perception and willingness to use beef traceability. The data were collected from 255 housewives in Busan and Gyeongnam region through a self-administered questionnaire. Frequency, Cronbach's ${\alpha}$, t test, one-way ANOVA, Duncan's multiple range test, Pearson's correlation analysis, and multiple regression analysis were conducted by SPSS Windows V.20.0. Only twelve percent of the respondents experienced to use beef traceability. Most respondents checked it by kiosk or bar code reader in a store. On the other hand, eighty-eight percent did not use beef traceability. The reasons for not usage of it were "Do not know beef traceability very well", "Do not know how to use beef traceability", and "Information from packing or counters is reliable" in order. In the level of perception of beef traceability, safety assurance was highest, followed by information quality, usefulness, and information accessibility. The percentage of correct answers of knowledge about beef traceability was not high. The multiple regression analysis showed that employment status, knowledge about beef traceability, information quality, information accessibility, and usefulness were significant factors to affect the willingness using beef traceability.

  • The purpose of this study was to identify the characteristics of consumers who purchase home meal replacements (HMR) and to analyze the differences for frequency of use, preference, satisfaction, and repurchase intention based on HMR product categories. The subjects were adults in their twenties or older, who had used HMRs and lived in Seoul and the Gyeonggi Province of Korea. Five-hundred and fifty subjects were chosen by random sampling, and questionnaires were distributed from March 12 to 30, 2005. A total of 451 questionnaires were returned (the rate of return was 82%). The primary results of the study are as follows. First, by analyzing for differences based on the demographical characteristics of the HMR consumers, men had higher 'frequencies of use' and preference, whereas women had higher satisfaction and 'intentions to purchase again.' This implies that HMRs assist women who are usually in charge of home food preparation, based on time and cooking effort; hence a higher satisfaction among the women. Second, by analyzing for differences based on the characteristics of HMR consumers who ate the products, 'frequency of use' (p<.001), preference (p<.01), satisfaction (p<.001), and 'intention to repurchase' (p<.001) for the 'ready to eat' HMR category, by the person who prepared the food, were significantly higher for those subjects in their 20s than for those in other age groups. As for persons influenced by the meal, the teen age group had significantly lower 'frequency of use'(p<.001), preference (p<.05), satisfaction (p<.01) and 'intention to repurchase' (p<.01) than other age groups. 'Frequency of use' (p<.001) and preference (p<.05) were lower if the person influenced by the meal was one's spouse or child than if the person influenced by the meal was oneself. Third, regarding the preference for eating at home or eating out, 'frequency of use' was significantly higher than the other analyzed factors for the 'ready to eat,' 'ready to heat,' and 'ready to end-cook' HMR categories. In short, the 'frequency of use' for HMRs was higher for those who preferred to eat at home versus eating out, simply as a result of being bored with eating out, which is essentially the reason for the origin of HMR.

  • The purpose of this paper was to grasp some aspects of use of imported foods at the rural homes with the growing generation. So we put some questions to the 399 middle school and high school students. The results were as follows: (1) The number of the homes using the imported foods, which marks 56.9% of the whole, was higher than the number of the homes not using the ones. (2) Even though the use of imported foods had no relation with the occupations of the student's mothers, the degree of living quality, the situations of food consumption, and so on, however the use ratio was high at the homes of middle class. (3) The students of the home of using imported foods favored the traditional diets, and marked 63% of the objective students of investigation. The students who like the western style of diets marked the high frequency of the use of the imported foods. On the other hand, the students who like the Chinese foods used the meat and fishes and processed foodstuffs among the imported foods. (4) The frequency of instant foods for the carried lunches showed the meaningful relation with frequency of use of imported foods. (5) In the view of use of instant foods for the lunches, the group of people who carried the lunches 3 or 5 times per week used the imported meat foods, the other group who carried the lunches 1 or 2 times per week marked the high frequency of having coffee and tea.
