In recent years, to solve the increasingly prominent problem of the contradiction between human social development and environmental resources, artificial meat has appeared in public view more and more. Generally speaking, the artificial meat can be divided into vegetable protein meat and cell cultured meat. Among them, vegetable protein meat has gradually begun to be commercialized, and cell cultured meat is cultured with animal cells, which is more similar to the real meat. Based on the analysis of the essence of cell cultured meat, we explore the positive significance of cell cultured meat technology for the meat production industry, consumer groups, and the sustainable development of mankind in the future. From the perspective of bioethics, the research, development and production of cell cultured meat can help ensure the sustainable development of human society, improve animal welfare, reduce resource demand, improve the nutritional function of meat products, and provide new growth points for the development of other industries. In addition, the ethical risks of food safety, technology abuse and technical supervision involved in cell cultured meat production are put forward for deep consideration, hoping to provide reference for the sustainable development of artificial meat industry from the perspective of bioethics.

This study was conducted to offer basic data that give effective ways to inform the country-of-origin labeling, where the ingredients they are serving are from, at school foodservice and to reconsider the importance of the labeling origin based on the survey by the elementary school students. 96.0% of the elementary school students agreed to the regulation about the country-of-origin labeling and the older students were influenced more by media and also supported the labeling. About the tendency of ingesting food from the country the students didn't like, 69% of them disagreed to eat. In the ways to label the country-of-origin labeling at school foodservice, elementary school students recognized easily the indication of origin designed by menu items, letter type. 76% of elementary school students checked the country-of-origin labeling posted at restaurants. When the students eat out, 68% of them were unwilling to have the food using the ingredients from the country they don't like. The country-of-origin for main ingredients such as beef, pork, chicken and other meat products, rice, kimchi had high importance scores. We found that the students think about the country-of-origin for main ingredients is important. Consequently, education and public relations of the country-of-origin labeling for elementary school students would be required.

3.Attitude of dietitians working for elementary schools on meat products.
Journal of the Korean Dietetic Association 1997;3(1):30-43
This study was conducted to investigate the attitude of dietitians on meat products and consumption of meat products in meal service of elementary school. Eight hundred and forty two questionnaires collected from each district of the country were statistically analyzed. Dietitians showed preference of ham and packed meat to other meat products. Dietitians had a good image on meat product regarding it as a good source of protein, imported food and diversely used food for cooking. Whereas 50% and 25.8% of dietitians concerned about the high content of preservative and sodium, respectively. More than 96% of dietitians suggested the food processing company to decrease the addition of preservatives, coloring agents, color formers and sodium. Fifty nine percent of dietitians responded they would increase the consumption of meat product if it is processed to food with low sodium, low cholesterol, low fat and no persavatives. Dietitians used ham for cooking once or twice a month. The reason they used the meat product for meal service was the preference of students and readiness of meat product for cooking. The dietitian's favorite cooking method was roasting ham or sausage with vegetable. Dietitians responded the first thing they checked for purchasing meat product was the date of processing and the term of validity.

Adulteration in meat products is a widespread issue that could lead to serious threats to public health and religious violations. Technology that offers rapid, sensitive, accurate and reliable detection of meat species is the key to an effectual monitoring and control against meat adulteration. In recent years, high-throughput sequencing-based DNA metabarcoding technology has developed rapidly. With the characteristics of being high-throughput, highly precise and high-speed, this technology can simultaneously identify multiple species in complex samples, thus offering pronounced advantages in the surveillance of adulteration in meat and meat products. Starting with an introduction of the major developments in the high-throughput sequencing technology in the past two decades, this review provides an overview of the technical characteristics and research methods of DNA metabarcoding, summarizes the application of DNA metabarcoding technology in meat adulteration detection over the last few years, discusses the challenges of using DNA metabarcoding technology in the detection of meat adulteration, and provides future prospects on the development of this technology.

Somatic cell cloning (nuclear transfer) is a technique through which the nucleus (DNA) of a somatic cell is transferred into an enucleated oocyte for the generation of a new individual, genetically identical to the somatic cell donor. It could be applied for the enhancement of reproduction rate and the improvement of food products involving quality, yield and nutrition. In recent years, the United States, Japan and Europe as well as other countries announced that meat and milk products made from cloned cattle are safe for human consumption. Yet, cloned animals are faced with a wide range of health problems, with a high death rate and a high incidence of disease. The precise causal mechanisms for the low efficiency of cloning remain unclear. Is it safe that any products from cloned animals were allowed into the food supply? This review focuses on the security of meat, milk and products from cloned cattle based on the available data.

This study aimed to evaluate the effectiveness of the foodservice management support program focusing on menu management in community child centers. The support program provided reference menus, staff training, and field consulting to 10 community child centers in the Jeollanam-do province for one month, August in 2010. One month menus were developed, based on children's preference for menu items, foodservice personnel's preference for food materials, and availability of local specialty foods, and offered as reference menus. In addition, staff training and field consulting focusing on menu management were conducted before and during the pilot period, respectively. To evaluate the support program, menus, foodservice personnel's knowledge level and perceived performance in foodservice management, and children's level of satisfaction for foodservice were analyzed before and after the support program. As a result of analysis of 222 and 210 menus of before and after the support program, respectively, the number of dishes per meal increased from five to six on average, and the proportion of meals including five food groups, which were grain, meat, vegetable, fruit, and milk and dairy product, rose from 2% to 24%. Foodservice personnel's knowledge level regarding foodservice management increased significantly (p = 0.007), however, their perceived performance in foodservice management did not show any significant changes. Children were more satisfied with 'food' (p = 0.001), 'sanitation' (p = 0.001), and 'environment' (p < 0.008) of foodservice in community child centers after the support program. In conclusion, the foodservice management support program focusing on menu management in this study was effective for improving menu quality of and children's satisfaction with foodservice in community child centers.

The purpose of this study was to examine food habits and dietary behavior related to using processed food among male college students residing in dormitory and self-boarding in Gangwon. A total of 344 students (dormitory group: 227, self-boarding group: 117) were surveyed from May to June of 2012. The results are summarized as follows: self-boarding group had a significantly higher frequency of skipping breakfast and lunch and frequency of out meal compared with the dormitory group (p < 0.05, p < 0.05, p < 0.05 respectively). The self-boarding group had a significantly lower the score of 'eat vegetables and Kimchi at every meal' (p < 0.001) and 'eat a variety of food everyday' (p < 0.001) compared with the dormitory group. The self-boarding group had a significantly higher the preference for meat products (p < 0.05) and canned food (p < 0.01) for selecting processed food compared with the dormitory group. The consideration for selecting processed food was ranked by 'taste', 'price', 'expiration', 'appearance' and 'nutrition' in both dormitory and the self-boarding group. In the dormitory group, nutrition labels were identified certainly 2.6%, sometimes 12.8%, and rarely 17.2%. In the self-boarding group, nutrition labels were identified certainly 1.7%, sometimes 18.0%, and rarely 24.8%. The necessity of nutrition education was high in both dormitory group (51.6%) and the self-boarding group (62.4%). Therefore, development of an educational program and application of the information from nutrition labels for male college students, especially self-boarding students will be effective in improving dietary life in order to maintain healthy dietary habits.
