  • The world is in the process of a structural change related to ICT convergence knowledge industries. ICT is leading to the creation of new products and services, and is making our lives more convenient, safer, and more efficient. In advanced countries, many studies have been conducted with the goal of developing new business models converged with ICT, and this is also the case in the food industry. Korea possesses world-leading ICT, and if this ICT is applied to the food industry, a world-class new business model can be developed. The u-Food System, which is in the process of development in Korea, is a next-generation food system that can allow food providers, consumers, and distributors to access various types of information about food products, including traceability, distribution, safety, quality, and freshness, and manage this information. It is a future food system that converges ICT, biotechnology and sensing technology with food. Based on the u-Food System, this paper will introduce the status of current smart quality distribution technologies that converge ICT (such as sensor tag, sensor network, LBS, GIS, and CDMA) with food technologies (such as traceability, quality, distribution management) to manage the safety and quality of fresh food in the distribution process.

  • The purpose of this study was to investigate customer perception of food safety and food safety orientation behavior. A survey was conducted from 458 adults aged 20 and over. The results of this study showed as follows. Food safety was the most important consideration when purchasing food, followed by freshness, taste, nutrition, price, and quantity. 87.1% of respondents had more than usual concern about food safety, and women were more aware of food safety than men. The food safety information was usually acquired from the mass media (TV, radio, Internet). As for the reasons for food safety accidents, they pointed out in the order of lack of awareness of food safety, deficient sense of responsibility of the people who produce, lack of distribute and sell food products, and lack of legal system. In conclusion, it is expected that accurate information about food safety is efficiently communicated, and the government's continuous effort is needed. In addition, effective ways to inform customers of food safety should be identified. Long-term views should be considered when develope food safety related policies and food safety education.

  • This study was implemented to offer materials for the activation of On-line food shopping mall though census about purchasing food. A percentage of people who had accessed to On-line food shopping mall was 53.8%, and who had an experience of purchasing food at the On-line sopping mali was 18.9%. The number of food purchasing in On-line food market is $1{\sim}3$ times(67.7%). It is general that an amount of food purchase is less than 100,000 wons. And the health assistant food is the most interesting item followed by Meet, Special products like a laver and mushroom, and an anchovy. in purchasing food at On-line market, customer thought that the confidence and the freshness of food are important because customer can't choose a product directly. In the future of food purchase using On-line shopping mall, 38.1% of people show their intend of purchasing at the mall. People who had experience of food purchase though the Internet have more positive view about repurchase than ones had not.

  • Most fresh-cut agri-food products are less stable than unprocessed materials from which they are made. The objective of this study was the development of a quality control system for fresh-cut agri-food products. In this study, vitamin C, minerals, residual heavy metals, and pesticides of various fresh-cut agri-food products were analysed. Sensory evaluation revealed that overall acceptability scores were less than expected in most products since fresh-cut products are likely to cause browning and easily lose their freshness. Therefore, the postharvest technologies that can maintain the quality, freshness and appearance must be supplied. Although vitamin C and minerals are main nutrients that can be supplied from salads, the results showed that vitamin C and mineral contents were very small and extremely small compared with the values from the food composition tables. It is possible that vitamin C and most minerals that are easily destroyed were lost through minimal processes like peeling and cutting. In safety side, the remaining heavy metal contents of fresh-cut agri-food were investigated and the results showed that copper and lead existed in some products because only cadmium in agricultural produce is controlled by the minimum standard of heavy metal contents in Korea. No residual pesticides were detected in all products.

  • This study investigated the impacts from the recognition and satisfaction of Korean foods on the revisit intentions of japanese tourists to Korea. The subjects of this study consisted of 365 Japanese tourists visiting Korea. The findings are summarized as follows: (1) the recognition of Korean food included 'the quality of food material is fresh and good'(3.99 pints), 'Korean food is nutritious and healthful food'(3.89 points), and 'Koran food consisted of grains and vegetables, and the cooking methods were developed specially'(3.88 points) in the order. (2) They were highly satisfied with the 'nutrition of the food,' 'taste of the food,' and 'quantity of the food,' in terms of the Korean food quality however, they were not satisfied with 'Japanese marks on ingredients,' 'sanitary,' 'smell,' and 'freshness.' (3) The most influential recognition variables to affect revisit intentions to Korea was 'health knowledge' followed by 'unique,' 'preference,' 'experience,' and 'interest.' (4) The most influential satisfaction variable to affect revisit intentions to Korea was 'food and menu' followed by 'translation and understanding,' and 'flavor and appearance.'

  • There is no doubt that accumulation of big data using multi-omics technologies will be useful to solve human's long-standing problems such as development of personalized diet and medicine, overcoming diseases, and longevity. However, in the food industry, big data based on omics is scarcely accumulated. In particular, comprehensive analysis of molecular lipid metabolites directly associated with food quality, such as taste, flavor, and texture has been very limited. Moreover, most of food lipidomics studies are applied to analyze lipid components and discriminate authenticity and freshness of limited foods including vegetable and fish oil. However, if lipid big data through food lipidomics research of various foods and materials can be accumulated, lipidomics can be used in the optimization of food processing, production, delivery system, food safety, and storage as well as functional food.

  • Headspace volatile compounds of cold-stored and freeze-dried Krill Eupausia superba were analyzed to investigate their flavor qualities using a system combining a dynamic headspace isolator, an automatic thermal desorber, and a gas chromatograph-mass-selective detector. Levels of oxidation products of polyunsaturated fatty acids such as aldehydes, alcohols, and ketones, which are known to give seafood a nasty smell because of their low flavor threshold values, increased during cold storage of krill. Notably, levels of 2-methylpropanal, 3-methylbutanal, 2-methylbutanal and 2-butanone increased during its storage. They can be considered index compounds of off-odor according to freshness degradation during storage. By contrast, in freeze-dried krill powder, levels of aldehydes, ketones, and aromatic compounds decreased rapidly. Only alcohols, which did not greatly affect the food flavor, were isolated in large amounts. It was confirmed that levels of oxidized compounds of krill increased during cold storage, but decreased in freeze-dried krill.

  • In order to secure competitiveness of the home meal replacement (HMR) industry from a long-term perspective, development of packaging and processing technologies must be achieved. The development of technology that can secure freshness, nutrition, and taste but secures the shelf life is the key to the future growth of HMR. The future of HMR can be considered in terms of nutrition, environment and safety. From the nutritional point of view, it is expected that development of healthy HMR such as low-salt, low-sugar, low-fat, and high fiber and premium HMR with functional ingredient enhanced, and personalized HMR for silver, infant and patients will be done. And it is expected that development of HMR utilizing environmentally friendly food or local food, development of energy reduction and environmentally friendly disinfection technology, development of environmentally friendly packaging material, and providing information on HMR preparation using QR code and RFID from the environmental and safe point of view.
