The purpose of this study was to examine the current status of patents related to dietary life of the elderly in Korea. Using Korea Intellectual Property Rights Information Service, patents registered between 2002 and 2013 were searched with the key words including 'elderly or the aged' and 'food, meal, or dietary life.' The search results showed 1,438 patents, and 500 patents meeting the research purpose were selected and analyzed. They were divided into two categories: 'patents on foods' and 'patents on products and services related to dietary life.' The former was further divided into four subgroups as follows: foods for health promotion, foods for disease prevention, foods for the people with difficulty in swallowing and masticating, and others. Also, the latter was divided into products or services. The results showed that patents on foods accounted for about 90%, of which the patents on foods for health promotion were ranked as the highest (40%). The number of patents on products and services related to dietary life was relatively small, indicating that the technology development has been focused on foods. Therefore, the technology for products and services related to dietary life should be actively developed as well as that for foods to improve the quality of life for the elderly in the future.

Purpose: Cold storage is the most popular method used to preserve highly perishable foods such as beef and fish. However, at refrigeration temperatures, the shelf life of these foods is limited, and spoilage leads to massive food waste. Moreover, freezing significantly affects the food's properties. Ice crystallization and growth during freezing can cause irreversible textural damage to foods through volumetric expansion, moisture migration induced by osmotic pressure gradients, and concentration of solutes,which can lead to protein denaturation. Methods: Although freezing can preserve perishable foods for months, these disruptive changes decrease the consumer's perception of the food's quality. Therefore, the development and testing of new and improved cold storage technologies is a worthwhile pursuit. Results: The process of maintaining a food product in an unfrozen state below its equilibrium freezing temperature is known as supercooling. As supercooling has been shown to offer a considerable improvement over refrigeration for extending a perishable product's shelf life, implementation of supercooling in households and commercial refrigeration units would help diminish food waste. Conclusions: A commercially viable supercooling unit for all perishable food items is currently being developed and fabricated. Buildup of this technology will provide a meaningful improvement in the cold storage of perishable foods, and will have a significant impact on the refrigeration market as a whole.

This study analyzed in nutrient contents changes of adult's favorite foods between March 2019 and July 2020 after policy implementation nutrient-poor foods based on special act on safety control of adult's dietary life in Korea. Among adult's favorite foods manufactured or sold in 2020 as well as 2019, calories and key nutrients in breads, ice creams and pizzas were improved in comparison to those in the other food groups. However, most of the changes in calories or key nutrient contents exist. The newly introduced candies, breads showed slightly greater improvements in calories and key nutrient contents than in 2019. On the other hand, some negative changes were found in newly introduced chocolates in comparison to previous ones. Overall, policy implementation on foods seemed to induce changes in nutrient contents of adult's favorite foods. In particular, nutrition education is reported to have a positive impact on adult's frequency and preference for processed foods, and more systematic and continuous nutrition education measures should be devised to help adult as consumers selectively purchase healthy foods. This research is meaningful in that it is the first study to analyze the quality changes of adult's favorite foods since the high-calorie and low-nutrient food management policy.

This study was carried out in order to investigate the condition of storage and to evaluate preference of supplementary foods for infants using Korean foods. Thirty-four different kinds of supplementary foods were developed and fourteen representative ones were selected to be analyzed. A safety storage assay and sensory evaluation were conducted. The results are as follows: 1. In the safety storage assay, the microbiological quality of the products was good during the 13 day-storage in refrigerator. After 14 days, the total plate counts in the products were low and were determined safe. During the 17 day-storage in refrigerator, coliform was not found. 2. In the sensory evaluation, fruit products scored high in acceptability and cow liver products scored low.

This study was conducted to evaluated the nutrition quality of the commercial supplementary foods for infants and young children and to seek a solution to the establishment of standards of nutrient requirements for supplementary foods in Korea. Information on food ingredients, nutrient contents, claims about usefulness of food components and instructions for feeding preparation were obtained from the labels of 33 commercial supplementary foods manufactured by 4 different domestic companies. According to the standard of supplementary foods for infants and young children described in the Korean Food Code, the commercial supplementary foods were categorized into two different types, weaning food and baby food. All the commercial weaning foods were in powder form and mainly composed of cereals, whereas all the baby foods were mainly composed of fruits in the form of canned juice. The weaning foods contained more nutrients than the baby foods did, and the nutrient levels of the weaning foods expressed as nutrient density on energy basis were higher than the RDA for infants aged 5 to 11 months, suggesting that the commercial weaning foods provide adequate amounts of nutrients. If one followed the instructions for feeding preparation appearing on the label, however, recommended amounts of intake of the weaning foods would provide too much energy as well as nutrients. There were many differences in nutrient standards of weaning foods between the Korean Food Code and Codex international food standard. In conclusion, the establishment of standards for nutrient requirements for the supplementary foods requires significant scientific studies on what nutrients are the most inadequate in Korean infants and young children feeds and what levels of nutrients should be added to the foods in order to supplement their nutrition. In addition, it is very important to have a strong scientific basis to support our standard when discrepancies exist between our standard and the international standard.

BACKGROUND/OBJECTIVES: Food composition databases are necessary for assessing dietary intakes. Developing and maintaining a high quality database is difficult because of the high cost of analyzing nutrient profiles and the recent fast-changing food marketplace. Thus, priorities have to be set for developing and updating the database. We aimed to identify key foods in the Korean diet to set priorities for future analysis of foods. SUBJECTS/METHODS: The food consumption data of the Korea National Health and Nutrition Examination Surveys 2013-2014 were used. We modified the US Department of Agriculture's key food approach. First, major foods were analyzed, contributing to 75%, 80%, 85%, or 90% of each nutrient intake. Second, the cumulative contributions to nutrient intakes were compared before and after excluding the foods least commonly consumed by individuals. Third, total nutrient score for each food was calculated by summing all percent contributions times 100 for nutrients. To set priorities among the foods in the list, we sorted the score in descending order and then compared total percent contributions of foods, within the 100, 90, 85, 80, and 75 percentiles of the list. Finally, we selected the minimum list of foods contributing to at least 90% of the key nutrient intake as key items for analysis. RESULTS: Among the 1,575 foods consumed by individuals, 456 were selected as key foods. Those foods were chosen as items above the 80 percentile of the total nutrient score, among the foods contributing at least 85% of any nutrient intake. On an average, the selected key foods contributed to more than 90% of key nutrient intake. CONCLUSIONS: In total, 456 foods, contributing at least 90% of the key nutrient intake, were selected as key foods. This approach to select a minimum list of key foods will be helpful for systematically updating and revising food composition databases.

This study was conducted in order to better understand the local and specialty foods of the Yeong-ju region. This study provides basic data for new menu development and commercialization. The results of 384 surveys, which were conducted to determine traditional rice cake production methods and their traits, were analyzed. Samgyetang was ranked top in the survey on recognition, public interest, and frequency of the local foods. Dakjuk was ranked second, followed by Baechujeon and Bopguk, in order. The levels of recognition and preference of specialty foods were in the order of hasuo, peach, apple, and meat. Among the answers in the survey on the popularization and commercialization of local foods, changing of the cooking style for younger generations' taste was considered to be the most important. Holding events to promote regional specialty foods and initiate the public to traditional cooking styles were listed sequentially by importance. The survey results show that promotion of local foods through education, and as well as incorporation of new ingredients are both highly effective ways to commercialize local foods for tourism. The results also indicate that taste, nutrition, and appearance of food should be considered in order to improve quality.

The Purpose of this study was to propose the most effective packaging method and storage conditions to apply to home-delivered meals for the elderly Changes in the physical and sensory qualities of pan fried oak mushroom and meat, soy sauce glazed hair tail and roasted dodok, in wrap packaging, top sealing and vacuum packaging were evaluated during storage at 25, 4 and -18$^{\circ}C$, for 5 days. The speed of falling-off in the foods qualities, under chilled and frozen storage conditions did not differ much as the 5 day storage period was too short for a proper assessment. The sensory characteristics of taste and texture were better evaluated in the chilled than in the frozen storage. The most effective packaging method at all the storage temperatures was the vacuum packaging, which assured the safety of the foods by the removal of oxygen. The lightness, springiness and hardness were significantly influenced by the storage temperature, period and packaging method, while the sensory characters were affected by storage temperature and the period. In conclusion, the quality of the vacuum packed pan fried oak mushroom and meat and soy sauce glazed hair tail, in frozen storage, were still fresh after the five days of the experiment. The shelf-life of those foods with wrap packaging, in chilled storage, were suggested to be three days. The quality of the roasted dodok, with vacuum packaging in chilled storage, was preserved for five days.

This study was to investigate consumers' recognition, knowledge and purchase attitude on genetically modified(GM) foods in Daejeon area. Data of 283 questionnaires were analyzed by using the SPSS(Ver. 17.0)program. Most of the subjects were women (91.9%), distributed 30's(41.7%) or 40's(31.8%), and graduated from university(41.3%). The kinds of GM foods that many subjects had known were soybean, corn, tomatoes and potatoes. The subjects answered that there were GM foods in supermarket items were 71%. Consumers' recognition on the safety of GM foods was 'somewhat anxious'(65.4%). After confirming which their purchasing item is GM foods, 'they will buy it case by case'(60.1%) or 'they will never buy it'(27.9%). The most reason of never buying GM foods was 'harmful to health'(82.3%). The first reliable information sources on GM foods were medical institutes and professionals. The knowledges about GM foods were significantly higher in 20's and 'less than 1year' of marriage duration than the other groups(p<0.05). On the purchase attitude of GM foods, the 20's responded favorably compared to other groups (p<0.01). Subjects' opinion on the necessity of development on GM foods tended to higher in 40's and 'less than 2 million won' of monthly income than the other groups. For the reason about necessity of it's development, 'nutritional, functionality and quality improvement' was 53.7%. In conclusion, many consumers regard that GM foods is not yet safe for health. Accordingly, government and research institutes should examine thoroughly and research continuously for the safety of GM foods. They must announce to consumers accurate information about GM foods.

This study was conducted to examine the perceptions of residents in the Chungcheong area on the commercialization of traditional Korean foods as convenience foods. Data was gathered using a questionnaire designed to evaluate the concerns, satisfaction, and Knowledge of traditional Korean food as well as the perceptions on commercialization of Korean traditional foods as convenience foods. In order to measure traditional food recognition and interests related to health, a 5-point Likert scale was employed and 374 subjects were surveyed. The results are summarized as follows : Most of the respondents expressed concerns for traditional Korean foods. In the over 50 age group, degree of interest (p<0.01), knowledge (p<0.01), and satisfaction (p<0.01) with regards to traditional foods was higher than in other age groups. The professional group had higher degrees of interest, knowledge, and satisfaction about traditional foods than the general group. Based on monthly income, for respondents earning over 3,010,000 won/month, the knowledge rating for traditional foods was higher than in the under 3,000,000 won/month group. The professional group had a more positive view of the commercialization of traditional food as convenience food than the general group. Respondents deemed quality improvements and an increase in consumption as reasons for the commercialization of traditional foods. Those with a greater recognition of traditional foods also had a higher degree of interest for the foods. Efforts for the commercialization of traditional Korean foods will help with consumer menu choices menu development and systems management of Korean traditional foods.
