The objective of this study was to prepare the base on which Korean food can become a globally important health food. A focus group interview was conducted with a nutritionist and professor of food and nutrition to select the Korean food for a healthy menu. Five main categories were established to select a healthy menu based on the Korean food philosophy, including Korean food made from beans, Korean food made using fermentation, Korean food made using various colors, Korean food with high dietary fiber, and Korean food made with abundant unsaturated fatty acids. The 52 healthy menu items selected based on these standards were composed of easily available food materials. The efficacy of food materials described in Sikryochanyo, the traditional Chosun dietary therapy, was checked to verify the efficacy of this healthy menu. This study demonstrated that basic materials can be efficiently used to enable citizens to select Korean food as an international health food. As such, the results can be utilized to publicize Korean food as a healthy food.

Recently demand for safer and healthier food has augmented with advancements in health conditions. Food ingredients with yet to be known safety and functionality, are being investigated for their safety or detrimental effects. The Ministry of Food and Drug Safety has introduced "health functional food" by the "Health Functional Food Act" to evaluate bio-functional and safety properties of raw materials using standard methods including in-vitro and in-vivo testing before human consumption. Despite recent growth in net worth of domestic functional food market, most of the raw materials are not from local Korean industries with own research and development, and mostly terrestrial not marine resources. Geographically, Korea has access to diverse marine bio-resources that need to be managed and utilized sustainably. Recently, diverse novel physiologically active substances have been reported from marine organisms. Hence, the development of functional foods from marine bio-resources is considered as an inevitably important task.

Agar-based composite films were prepared with variety of food processing and agricultural processing waste materials in order to screen natural lingo-cellulosic resources for the value-added utilization of the under-utilized materials. The effect of these waste materials (10 wt% based on agar) on mechanical properties, moisture content (MC), water vapor permeability (WVP), water absorption behavior of biocomposite films were investigated. Biocomposite films prepared with various fibers resulted in significant increase or decrease in color and percent transmittance. The MC, WVP, and surface hydrophobicity of biocomposite films increased significantly by incorporation of fibers, while the water uptake ratio and solubility of the film decreased. SEM images of biocomposite film showed better adhesion between the fiber and agar polymer. Among the tested cellulosic waste materials, rice wine waste, onion and garlic fibers were promising for the value-added utilization as a reinforcing material for the preparation of biocomposite food packaging films.

Glycosides are important functional materials in foods. Transformation, especially hydrolysis, of the sugar moieties tends to improve the functional properties of the administered glycosides in vivo. Various probiotic bacteria and edible food-grade fungi such as bifidobacteria, lactobacilli, leuconostocs, yeasts, and aspergilli are potential industrial microorganisms to transform glycosides of ginsenosides from ginseng, platycodin saponins from Platycodon grandiflorum, Trignoella foenum-graecum (TFG) saponins, and isoflavones from soybeans and Puerariae radix, respectively, by fermentation or enzymatic reaction. In this review, various transformation pathways bearing potential significance with respect to the changes in structure and function of the various glycosides from the food materials will be introduced. In conclusion, the proper combination of food microorganisms and transformation conditions will improve the functionality and the sensory value and reduce the cytotoxicity of the functional glycosides present in various functional food raw materials.

This study was conducted to investigate the use and acceptability of pre-processed food materials in school foodservice. Self-administered questionnaires were collected from 81 schools in the Kyunggi area. Statistical data analysis was completed using the SPSS v. 10.0 program. Eighty-one school dietitians from 31 elementary, 31 middle, 19 high school participated in the survey. Most of the subjects (over 95%) understood that it is necessary to use pre-processed foods, and they considered food hygiene as the most important factor. The percentages of school foodservices that purchased and used pre-processed foods were: 82.7% for cabbage, 86.4% for onion 72.8% for carrot, 97% for garlic, 82.7% for potato, and over 90% for meats and fishes. Dietitians were most satisfied with the performance of ‘trash reduction’, and ‘saving cooking time’ when using pre-processed food materials. ‘Appearance’, ‘freshness’, ‘hygiene’, ‘nutrition’, and ‘specialty of the food-processing company’ were aspects of the most concern when purchasing and using pre-processed food materials.

Novel food materials can be produced based on biotechnology such as genetic recombination, microbial fermentation, and enzymatic engineering by utilizing living organisms such as animal, plant, and microorganism or by applying the enzymes isolated from them. Especially, exploration and development of novel prebiotics and probiotics attracted great attention worldwide in the food industry, of which the research and industrial trends in food biotechnology field are promoting the production of next generation sweeteners and proliferation of beneficial bacteria in gastrointestinal tract. Development and commercialization of novel food materials by domestic bioprocessing technology have been sluggish due to the GMO/LMO food safety issues. Meanwhile, the US and EU do not perceive badly about gene manipulation technology, and the research is most active in the fields of crops and GMMs, respectively. Genetic scissors, which are considered as next generation technology, are notable since foreign genes do not remain in final products.

Amount of residual ink solvent on the packaging materials from Korea, Japan and Europe was measured and compared. The amount of packaging materials from Korea was much higher than that of Japan and Europe. To reduce the residual amounts of ink solvent, aging condition of printed packaging materials including aging time and temperature was modified and evaluated. Aging with high temperature and short time ($60^{\circ}C$ and 24 hours) was more effective for reduction of residual amount of ink solvent than that with low temperature and long time. To find out change of reduction pattern of residual amount of solvent according to plastic packaging material, several monolayer and multilayer packaging materials were selected. Among the monolayer packaging materials, the amount of EVOH and PET was lower than that of polyolefin plastic film including PE and PP. PP/EVOH/PET among the selected multilayer film showed the lowest amount of residual ink solvent on food packaging materials. Result of this research revealed that the residual amount of ink solvent can be reduced by proper selection of aging condition with and by appropriate application of mutilayer plastic film.

To save cost and time in Kimchi manufacture, the use of raw red-pepper paste and device-mashed vice materials, in place of dried red-pepper powder, was examined. Two kinds of Kimchi were prepared: One with dried red pepper powder and device-not mashed vice materials and the other with raw red pepper paste and device-mashed vice materials. Then pH, total acidity, total viable cell counts, total lactic acid bacteria and sensory characteristics were evaluated. Comparisons of the two Kimchis, indicated that changes in pH, total acidity, the total number of viable cells and total lactic acid bacteria were similar between the two groups. The acceptability score of the Kimchi made using the raw red pepper paste and device-mashed vice materials was slightly lower than that of Kimchi made using the dried red-pepper powder. This color was indistinctly changed since the vice materials were mashed and mixed. In conclusion, the results indicate that when manufacturing Kimchi using device-mashed vice materials, Kimchi of better quality can be made by adding dried red-pepper powder.

The objective of this study is to investigate the satisfaction of elementary, middle and high school nutrition teachers in the Chungnam province concerning the free school food service. We surveyed satisfaction related to policies on school food service and the school food service center. Satisfaction on the school food service center was separated according to four dimensions; perception, food materials, operational system and service. Furthermore, we analyzed factors that affect satisfaction with the school food service center with a multiple regression model. First, satisfaction about the free school food service and dietary life education are higher than the total average of satisfaction with the policy about the school food service. Second, satisfaction about a variety of food materials and reasonable prices are lower than total average of satisfaction with the school food service center. Third, when more teachers have a high level of a positive perception and have higher satisfaction with the operational system of the school food service center, then they also subsequently display higher satisfaction with the school food service center. Therefore it is necessary to improve or make up for pricing and diversity on food materials by the school food service center.
