Korean government has endeavored to increase the exportation of agro-food, and the exporting processed food is one of the main concerns. However, there is little research to promote the exportation of Korean processed food, which is discussed in this paper. This paper analyzed the current situation of the exporting processed food and the government policy in Korea, and presents the strategy to increase the exporting. First, government programs should consider the market efficiency. Second, specified marketing strategies need to be developed after the overall analysis about the world market. Third, governmental support for product development and promotion should be expanded. Forth, efforts to increase the efficiency of logistics and food safety need to be magnified.

The principal objective of this study was to assess the bone density and processed food intake behavior of middle-aged and elderly women in the Seoul area. The subjects were assigned to one of the following groups on the basis of BMI: namely, the underweight, normal, and overweight groups. The results are summarized as follows: The average BMI and systolic blood pressure of the three groups were 19.0, 127.3 mmHg; 22.4, 132.8 mmHg; and 26.8, 136.1 mmHg respectively. The BQI and T-scores of the three groups were as follows: 56.6, -2.50; 62.3, -2.22; 66.0, -2.03 respectively. The bone status of the three groups, in terms of the percentage of normal and osteoporosis, were 9.5%, 52.4%; 8.3% 33.0%; and 8.8%, 23.6% respectively. We noted no significant differences in processed food intake (frozen, cold and can processed food, instant and convenience store food, basic side dishes) behavior among the three groups. However, we recorded a negative value between processed food intake and bone density (BQI, T-score, %young adult, Z-score, %age-matched) generally. In particular, ramyeon (r=-0.1574, p<0.05) and cup-ramyeon (r=-0.1996, p<0.05) intake were significantly associated with the T-scores of bone density levels. The results of this study revealed that processed food intake was not generally desirable for healthy bone. Thus, practically and systematically organized education regarding a good and healthy dietary life is highly recommended.

The purpose of this study was to investigate school dietitians' use of processed and packaged foods in Incheon. This study was carried out through a questionnaire and the subjects were 203 school dietitians in Incheon. The results are summarized as follows. Dairy product was the processed and packaged food used most frequently by the subjects for school lunch. Most subjects used processed and packaged foods for school lunch once or twice per week. The first criteria for their choosing processed and packaged foods was manufacturing company. Also major reason for their using processed and packaged foods for school lunch was saving cooking time, easy purchase, hygienical packing and less garbage. The most common information source on processed and packaged foods for school lunch was promotion of food company. The subjects checked labelling of processed and packaged foods in order of open-date, manufacturer, origin of product, nutrition facts, ingredients and food additives. Some results were significantly different among the subjects by employment school, type of meal management and cost per meal. For children and adolescents' nutrition and well-being through school lunch, it is necessary to prepare a database of the processed and packaged foods and education program concerning nutrition labelling and food safety.

The purpose of this study was to examine the extent of purchase of processed foods and the awareness about food label among middle school students. This survey was conducted by involving 350 middle school students in Incheon city, Korea from June 17~19, 2015. Middle school students consumed confectioneries, bread, carbonated drinks, and juices and ice creams once or twice a week at the rate of 53.4, 53.0, 40.6, and 36.9%, respectively. The most frequent place, time, and reason to purchase the processed foods were 'convenience store (36.2%)', 'after school (26.8%)', and 'hunger (77.9%)'. The subjects exhibited top priority (57.0%) on the taste at the time of purchasing the processed foods. Interestingly, the girl-students (44.7%) checked the labels of food more than the boy students (34.0%). The reasons for checking the food labels included acquiring significant information about the shelf life (27.0%), price (18.1%), nutrient (19.1%), and food additives (14.1%). Among the food labeling information, the name of the product (55.7%), the date of manufacture (49.3%) and the content (32.6%) were checked mainly by the subjects. In addition, the major reason for not confirming the food labeling was 'the food label was too small or crude (31.9%)'. It is necessary to inform about the processing methods and ingredients of the processed to middle school students so that they can make the correct choice of processed foods. Development of proper education methods on nutrition for middle school students is necessitated for healthy living.

Tailored nutritional education is generally found to be more effective in changing behaviors and to be more fully implemented than a non-tailored equivalent. This study was conducted in order to develop tailored nutritional education materials on food additives in processed foods based on need and levels of knowledge of educational targets of elementary-school students in Seoul Metropolitan City. The focus group interview was conducted with six elementary-school nutrition teachers in order to gather information and to develop a tailored quantitative questionnaire for the survey. Based on the results from 138 nutrition teachers, all answered that education on food additives in processed foods for students is necessary and both teachers and students need to receive education regarding definition, safety, and use of food additives for each processed food, in the form of video, PPT, and teaching-learning plan. Nutritional education materials for two classes were developed using video clips (grocery shopping and cooking class) about food additives in processed foods, PPTs with activity papers, two teaching-learning plans, and school newsletters to parents. In conclusion, the current study warrants conduct of further studies short-term and long-term impacts and efficacy of tailored need-based nutrition education in promotion of healthy nutrition by conveying proper scientific knowledge regarding food additives in processed foods for elementary-school students.

In this study the perception and consumption of processed meat products by students in food service schools was investigated. The total number of subjects in Seoul and Gangwon province used for this survey was 569. The most preferred processed meat product for students was the fried pork cutlet(17.7%), followed by bacon(11.4%), ham(7.9%) and sausage(7.6%). The main reasons for the consumption of these processed meat products were 'good taste'(52.5%), 'convenience in eating'(18.8%) and 'as the parent buy'(18.8%). The preference for the processed meat products had a relatively high perception value(4.0). However, the effect of consuming processed meat products on nutrition and health had a relatively low perception value(2.9). Reasons for distrusting the processed meat products were attributed to 'bad influence by media'(25.9%) and the 'unsanitary manufacture'(23.6%). In regards to the question about sodium nitrite, most of the students(56.2%) replied that they had 'never heard of it' or 'didn't know it well'. In conclusion, an improvement in public information would be a prerequisite for expanding wholesome use of processed meat products.

This study was performed to investigate the effect of dietary processed sulfur supplementation on water-holding capacity, color, and lipid profiles of pork according to the level of dietary processed sulfur (0%, CON; 0.3%, S). The pigs were slaughtered at an average final weight of 120 kg, and the longissimus dorsi muscles were collected from the carcasses. As results, pork processed with sulfur had significantly higher moisture and ash contents compared to those of CON but lower crude fat, pH, expressible drip, lower redness and yellowness, and greater lightness. Pork processed with sulfur showed significantly lower total lipid content, triglycerides, and atherosclerosis index but significantly higher high-density lipoprotein cholesterol. Feeding processed sulfur significantly lowered myristic acid, heptadecanoic acid, and stearic acid contents, whereas monounsaturated fatty acids and oleic acids were significantly higher compared to those in the CON. Higher amounts of polyunsaturated fatty acids and n-6 fatty acids were observed in the pork processed with sulfur than that of the CON. Therefore, supplementing pigs with dietary sulfur improved nutrient and meat quality.

Objectives: In this study, we suggest a Korean NOVA food classification that can be applied to food consumption among Korean. Based on this suggestion, the nutritional intake of Korean adults from ultra-processed foods (UPFs) was estimated. Methods: Korean commercial food was categorized based on the NOVA food classification criteria through the Korea Food Code and expert meetings. Then, the nutrient intake status of 6,991 participants in the 2018 National Health and Nutrition Examination Survey was analyzed according to the food processing level. Then, 4,152 adult participants (age 19-65) were divided into quartiles on the basis of their intake of UPFs, and the nutrient intakes from UPFs were compared. Results: Korean NOVA Food Classification defines with priority Group I (Unprocessed/ Minimally processed foods) and Group II (Processed culinary ingredients) foods based on the food cooking or consumption. Then, Group III (Processed foods) and Group IV (UPFs) are classified according to whether the characteristics of the raw materials used are maintained or whether the food was consumed before the 1970s. Our analysis results showed that most of the calories in the diet were consumed by Group I (52.7%), followed by Group IV (29.3%). After categorization of the adult participants into four groups according to their energy consumption from UPFs, we found that the highest consumption group (Q4) was younger and had higher percentage of men than women. The comparative analysis of the consumption of ultra-processed foods by Korean adults revealed that participants of a younger age and men consumed higher energy from UPFs than older participants and women, respectively (P < 0.01). Furthermore, the larger intake of UPFs was associated with an increasing trend for a higher intake of energy, sugar, saturated fat (P for trend < 0.001), total fat (P for trend = 0.021), and sodium (P for trend = 0.005), whereas the intake of carbohydrate, protein, and dietary fiber had a decreasing trend (P for trend < 0.001). Conclusions: With the current increase in the consumption of processed and ultra-processed foods, it is important to carefully consider not only nutrient intake but also the level of food processing.

The identification of pork in commercially processed meats is one of the most crucial issues in the food industry because of religious food ethics, medical purposes, and intentional adulteration to decrease production cost. This study therefore aimed to develop a method for the detection of pork adulteration in meat products using primers specific for pig mitochondrial DNA. Mitochondrial DNA sequences for pig, cattle, chicken, and sheep were obtained from GenBank and aligned. The 294-bp mitochondrial DNA D-loop region was selected as the pig target DNA sequence and appropriate primers were designed using the MUSCLE program. To evaluate primer sensitivity, pork-beef-chicken mixtures were prepared as follows: i) 0% pork-50% beef-50% chicken, ii) 1% pork-49.5% beef-49.5% chicken, iii) 2% pork-49% beef-49% chicken, iv) 5% pork-47.5% beef-47.5% chicken, v) 10% pork-45% beef-45% chicken, and vi) 100% pork-0% beef-0% chicken. In addition, a total of 35 commercially packaged products, including patties, nuggets, meatballs, and sausages containing processed chicken, beef, or a mixture of various meats, were purchased from commercial markets. The primers developed in our study were able to detect as little as 1% pork in the heat treated pork-beef-chicken mixtures. Of the 35 processed products, three samples were pork positive despite being labeled as beef or chicken only or as a beef-chicken mix. These results indicate that the developed primers could be used to detect pork adulteration in various processed meat products for application in safeguarding religious food ethics, detecting allergens, and preventing food adulteration.
