Objectives: The purpose of this study was to examine the coverage of the current mandatory nutrition labeling system on the nutrient intake of Koreans. Methods: KNHANES dietary intake data (2013) of 7,242 subjects were used in the analysis. KNHANES dietary intake data were collected by a 24-hour recall method by trained dietitians. For analysis, all food items consumed by the subjects were classified into two groups (foods with mandatory labeling and other foods). In the next step, all food items were reclassified into four groups according to the food type and nutrition labeling regulations: raw material food, processed food of raw material characteristics, processed foods without mandatory labeling, and processed foods with mandatory labeling. The intake of energy and five nutrients (carbohydrate, protein, fat, saturated fat, and sodium) of subjects from each food group were analyzed to determine the coverage of the mandatory nutrition labeling system among the total nutrient intake of Koreans. Results: The average intake of foods with mandatory labeling were 384g/day, which was approximately one quarter of the total daily food intake (1,544 g/day). The proportion of energy and five nutrients intake from foods with mandatory labeling was 18.1%~47.4%. The average food intake from the 4 food groups were 745 g/day (48.3%) for the raw food materials, 54 g/day (3.5%) for the processed food of raw material characteristics, 391 g/day (25.3%) for the processed foods without mandatory labeling, and 354 g/day (22.9%) for the processed foods with mandatory labeling. Conclusions: Although nutrition labeling is a useful tool for providing nutritional information to consumers, the coverage of current mandatory nutrition labeling system on daily nutrient intake of the Korean population is not high. To encourage informed choices and improve healthy eating habits of the Korean population, the nutrition labeling system should be expanded to include more food items and foodservice menus.

This study was conducted to investigate the current use and the demand for processed rice food products by full-time and working housewives in a metropolitan area. Out of 330 questionnaires distributed, 300 were analyzed(90.9% response rate). It was revealed that more than half of the respondents(54.0%) had used processed rice food products, regardless of their occupation. Most respondents stated that they used rice food products because of the variety of the products, digestibility and the taste. The development necessity for processed rice food products was analyzed, showing that rice cake(3.86), rice sauce(3.64), and rice cookie(3.89) had the highest score in each category. The average demand for education and promotion of rice food products was 3.89; among 7 items, menu recipe using rice flour was highly demanded(4.18) by the respondents. Approximately 43.0% of the respondents agreed that the internet is the most effective method for learning about rice flour cooking, and the respondents who have used processed rice food products(59.5%) were more likely to attend education programs compared to housewives who have not used processed rice food products (44.5%)(p<.05). Full-time housewife(59.4%) had a greater tendency to participate in the education program than working woman(44.4%)(p<.001). The findings suggested that various processed rice flour products with convenience to use and prolonged shelf-life will be needed.

The purpose of this study was to evaluate the microbiological and sensory quality changes from packing methods(PE; $85{\mu}m$ thick, vacuum; PE+LLDP+nylon; $50{\mu}m$ thick), and storage temperatures($3^{\circ}C,\;10^{\circ}C\;and\;25^{\circ}C$) and length of storage(1, 2, 4, 6 day) on the different types of processed potatoes(washed, peeled, or cut). Microbiological quality decreased gradually and significantly throughout the storage period in all cases. The processed potatoes stored at $3^{\circ}C$ with vacuum packing after immersion in chlorine water showed the lowest microbiological growth and had higher scores for the sensory quality factors(appearance, flavor and texture). The processed potatoes stored at $10^{\circ}C$ were rated wily better appearance, but they showed unacceptable microbiological quality at up to 4 days of storage. Overall, a temperature of $3^{\circ}C$ is recommended to maintain acceptable of microbiological and sensory quality in processed potatoes used in foodservice operations.

Objectives: This study was conducted to estimate usual meat intake distribution, which may have been over/underestimated when estimations were made using only the third food codes of the Korea National Health and Nutrition Examination Survey (KNHANES). Methods: For this purpose, 24-hour recall data from the 2009 Korea National Health and Nutrition Examination Survey, which conducted a partial 2-day survey of food intake, were used. The Multiple Source Method (MSM) was used to estimate the distribution of the usual intake of red and processed meats. Results: The results of this study show that the mean intake of red meat was 45.07 g while that of processed meat was 4.33 g. These results are slightly higher than the consumption calculated using only tertiary food code, and the difference was statistically significant. Furthermore, characteristics of the estimated usual intake distribution were a smaller standard deviation, increased lower percentiles, and decreased upper percentiles compared to the 2-day mean intake distribution for both red and processed meats. The proportion of individuals not consuming red meat decreased substantially from approximately 37% to 0.7%. The proportion of consumption that exceeded 90 g, which is the upper limit of red meat intake recommended by the National Health Service (NHS), was only approximately 10% in the distribution of usual intake. Conclusions: As the consumption of processed foods is expected to continuously increase, caution is needed regarding the processes used to calculate food (group) intake to avoid over/underestimation. Moreover, use of KNHANES data to calculate the proportion of the population at risk of insufficiency or excess intake of certain nutrients or food (group), based on one day intake that does not address within-individual variation, may lead to biased estimates.

It has been many changes in traditional Korean food habits according to the improvement of household income levels and the rise of standard of living. Therefore, the pattern of consumption in animal origin processed/convenient foods would have changed. This research aims to find the tendency of consumption in some animal origin processed/convenient foods compared with typical Korean traditional foods according to household income levels. Therefore, this survey was made on 698 children from 10 elementary schools located in Seoul. They were divided into 6 groups according to their household income levels. The data were analysed using Chi-square test and F-test in SPSS package program. From this research, the following results were obtained: 1. Their average monthly household income levels were between 500, 000~1, 500, 000 won(64.2%) and their family were of mostly 4~5 members. There were no significant differences in children's physical status among various income groups. As the household. income level increases, the food expenditure per month increases and Engel's coefficient decreases. 2. The animal origin processed/convenient foods that have no significant differences are ham, sausage, milk, yogurt, canned fish, and fish meal. The high-income groups preferred bacon, cheese, pork cutlet, and fried chicken, compared to those of low-income groups. The low-income groups preferred crab-flavored meal, compared to those of high-income groups. 3. In some Korean traditional foods, there were significant differences according to income levels. Those were Bulgogi, baked fish, fried meat, cooked fish and meat with soy-bean sauce. Fried fish and anchovy have no significant differences in food intake frequency according to household income levels. Chicken and egg saute are liked by children in every income groups. 4. Between the animal origin processed/convenient foods and the typical Korean nonprocessed traditional foods, children preferred the former regardless of income levels. In conclusion, animal origin processed/convenient food consumption patterns were not affected by household income levels.

Background: This study was carried out to determine the physicochemical components of Rehmannia glutinosa (RG) fermented with Rhizopus delemar. Methods and Results: Physicochemical components such as changes in moisture content, pH value, total acidity, amount of reducing sugars as well as quantity of free sugars, free amino acids, and catalpol were investigated. Result showed that, the moisture content ranged from 64.26 to 65.51%. The pH and total acidity of the fermented RG decreased significantly during fermentation. The reducing sugar content ranged from 0.10 to 1.34%. The most abundant main free sugars were identified as raffinose, xylose, glucose, fructose, and sucrose. The sucrose content in 80% ethanol and in water extracts increased during RG fermentation. In total, 26 free amino acids were detected, including seven essential amino acids. In addition, the quantity of free amino acids decreased significantly during fermentation. Finally, the catalpol content of the fermented RG was highest on the $2^{nd}$ day of fermentation at 2,028.67 mg/ 100 g. Conclusions: These results indicated that fermentation of Rhizopus delemar could be used to enhance biological activity, and that fermented RG could be used as a functional material and as an edible resource in food and functional materials industries.

This study was conducted to investigate the purchase patterns of processed foods and perception of school dietitians on nutrition labelling in Chonbuk area of Korea. Self-administered questionnaires were collected from a total 156 dietitians. Statistical data analysis was completed using the SPSS v. 11.5 program. The results were summarized as follows. Among the 156 school foodservice systems, 64.7% of schools were operated in conventional system and 35.3% were in commissary system. Among the processed foods, seasoning foods(98.4%) and cereal products(93.3%) were used widely in school foodservice. Among the general characteristics of schools and dietitians, the style(p<0.01), and type of foodservice(p<0.05), career, and age of dietitians respectively affected the purchasing pattern of the processed foods. Approximately 30% of dietitians responded that some fortified foods used for the meal preparation(eg. Ca-fortified yoghurt). Only 57% of dietitians who has more ten year job career was agreed with the important of fortified foods for the menu planning. Despite the levels of education of the dietitians became higher, were no relationship between the confidence on fortified foods and the improvement on health for children. About 96.2% of dietitians knew nutrition labelling of processed foods. Only 25.6% of dietitians checked nutrition labelling of processed food when they purchased these foods for school lunch. The main reason for their checking nutrition labelling of processed foods was for nutrient of products. The dietitians understanding and trust in nutrition labelling of processed foods were not high. But the half of dietitians responded that the nutrition labelling can be helpful for the purchase of processed foods in school foodservice systems. Therefore, it is necessary to activate the mandatory nutrition labelling of processed foods and to prepare its consumer education program for school dietitians.

Non processed onion (Allium cepa L.) powder or onion powder processed with ${\beta}-cyclodextrin+1%$ calcium chloride+1% soluble starch solution was added to the diet of 16 week old Wistar and spontaneously hypertensive rats (SHR) for 5 weeks. 36 SHR and Wistar rats were randomly divided into 3 diet groups, each of six. They were named control, NPO (non processed onion), PO (processed onion). The rats of the control group were fed diet without onion powder. To NPO and PO groups were added 5% of non processed onion and processed onion, respectively. Body weight gain, food efficiency ratio (FER), blood pressure, angiotensin converting enzyme (ACE) activity and Na excretion of urine and feces were analyzed. The processed onion and non processed onion diet reduced body weight gain without affeting the total food intake in Wistar rats (p<0.05). The body weight gain was lowest in Wistar rats fed with a diet with processed onion powder. The rats fed with diet containing PO or NPO had lower blood systolic blood pressure in SHR (p<0.05). The effect of onion powder on decreasing the blood pressure was not significant in Wistar rats. The ACE activity in lung was lowered in the SHR fed with either PO or NPO (p<0.05) compared to those fed with control diet. The urinary Na excretion was significantly lower in SHR than Wistar rats. The effects of PO and NPO on increasing the urinary and fecal excretion of Na were significant (p<0.05). These results suggest that onion processed with ${\beta}-cyclodextrin+1%$+1% calcium chloride+1% soluble starch solution to reduce volatile flavor, browning and caking preserves an antihypertensive effect of non processed onion.

A sruvey was conducted to investigate the consumer perception of farm products and processed foods, and to figure out the future direction of food supply system to satisfy the consumer need. From the citizens in Taegu area, 532 housewives were selected as sample subjects by stratified random sam-pling procedure. The main criteria of consumers for purchasing farm products was quality and the main reason for purchasing imported products was cheap price(48.9%). Most of consumers(87%) thought that food safety of farm products was not belong to safe level. Consumers(79.7%) perceived that the labeling system for the place of origin and for the quality are necessary, but they did not have confidence in the current label. Nearly all the subjects(93.6%) were concerned about the hazardness of residual chemicals of imported products, desired the rigorous inspection system for imported products. Consumers in Taegu area had confidence in processed foods in the following order; farmerbrand-product(0.9%), government-authorized farm product(30.0%) and agricultural cooperative association product(26.4%). However, only 73.6% of the consumers had the experience to purchase farmers' processed foods. As a conclusion, it appeared that nutrition education for consumers on food-decision making is strongly required for the substantial segment of population who are still ignorant of safety of imported product and food distribution system.
