  • The development of functional foods started booming from several years ago in the world. The size of functional materials are in the range of micrometer level. This size can be much smaller into nanometer level to be more effective. We face some problems from the materials, such as flavor, taste, color, viscosity, etc. in functional materials. The problems can be solved by micro / nanoencapsulation technique. This paper showed some results of the research related on the technique for functional milks and dairy products. The nono / microcapsules are the form of liquid instead of solid. Coating materials used were fatty acid esters, and core materials were lactase, iron, ascorbic acid. isoflavone, and chitooligosaccharide. The ranges of capsules are from 100 nm to 200 ${\mu}$m. The sample milks added nano/microcapsules were homogeneous and prevented the defects of core materials. It was observed that nano / microcapsules in milk and dairy products were effective as functional material without defaults. It was indicated that targeted functional foods can be developed further in various foods by nanotechnology.

  • In this study, the detection method was developed using molecular biological technique to distinguish authenticity of animal raw materials. The genes for distinction of species about animals targeted at Cytochrome c oxidase subunit I (COI), Cytochrome b (Cytb), and 16S ribosomal RNA (16S rRNA) genes in mitochondrial DNA. The species-specific primers were designed by that Polymerase Chain Reaction (PCR) product size was around 200 bp for applying to processed products. The target 24 raw materials were 2 species of domestic animals, 6 species of poultry, 2 species of freshwater fishes, 13 species of marine fishes and 1 species of crustaceans. The results of PCR for Rabbit, Fox, Pheasant, Domestic Pigeon, Rufous Turtle Dove, Quail, Tree Sparrow, Barn Swallow, Catfish, Mandarin Fish, Flying Fish, Mallotus villosus, Pacific Herring, Sand Lance, Japanese Anchovy, Small Yellow Croaker, Halibut, Jacopever, Skate Ray, Ray, File Fish, Sea Bass, Sea Urchin, and Lobster raw materials were confirmed 113 bp ~ 218 bp, respectively. Also, non-specific PCR products were not detected in compare species by species-specific primers. The method using primers developed in this study may be applied to distinguish an authenticity of food materials included animal raw materials for various processed products.

  • This study provides standardized scientific criteria for education materials on nutrition and diet that could be used in schools, workplaces, and health and medical facilities. The study was conducted from April 2011 to October 2011. Literature reviews, institutional visits, and telephone interviews were conducted for the first draft of the accreditation criteria. Expert meeting and advisory councils were conducted in order to obtain feedback after development of the first draft of accreditation criteria. In order to verify the validity and reliability of the first draft on certification criteria, a survey was sent out to 143 professionals, including professors, researchers, health and medical experts, teachers, nutrition teachers, dietitians, and clinical nutritionists. After several modifications, the final accreditation criteria were established for 1) printed materials (authority, credibility, objectivity, organization, editing, real-life usability, activities and participation, and public interest), 2) web-sites (authority, credibility, objectivity, design, real-life usability, accessibility, currency, and public interest) and 3) materials with activities (credibility, organization, design, convenience of utilizing, safety, and public interest). Out of several criteria, contents (authority, credibility. and objectivity) and publicity (public interest) areas are mandatory requirements. For the accreditation, books for learning and materials with activities are required to meet more than six evaluation components, and the other materials are required to meet more than five evaluation components, including the required area. Accreditation criteria developed in this study could be used as a standard for development or selection of good education materials for nutrition and dietary life.

  • The core of cooking, or a final stage in the full process of so-called artistic cooking, should be treated with insourcing. Reduction of several cooking processes resulted in shortened cooking time, increased efficiency, faster cooking, cutting the waiting-lines, and finally more room for customers. The outsourcing system can reduce or eliminate the following processes in cooking: buying various food materials, checking, storing, preparing, and processing. Especially in the Western food cooking department of a hotel, the outsourcing system should be enforced to make an economic kitchen and to efficiently manage it.

  • This study was designed to establish Korean food culture by analizing 17 sets of Jinyounuigue(진연의궤) Jinchanuigue(진찬의궤), and Jinjarkuigue(진작의궤) which were the records of royal party procedures in Yi dynasty. Side dishes were classified into 20 groups in this study ; Tang (場) 19, Jungol (전골) 3, J'im 18, Jun (전) 20, Jock 14, Pyunuk (片肉) 14, Cho 12, Hyae 17, Po 8, Chae 3, Bung 1, Nanri 1, Sooran 1, Sookran 1, Jaban 1, Kimchi 2, etc. all of 140 different kinds of side dishes. There was no tendency in omission or addition of food materials. Food materials were beef, pork, lamb, chicken, duck, peasant meat, dock's egg, fish, shellfishes, mollusca, curstacea, seaweeds, vegetables, fruits, beancurds, muk (a starch jelly), d'ock, muchrooms, etc. Seasonings were soysauce, pepper, sesame oil, ginger, green-onion, garlic, bean paste, ginger powder, red pepper powder, red pepper paste, salts, vinegar, honey, sesame power, etc.

  • Traditionally, food and medicines are considered as having common roots. That is, their energies share the same source (藥食同源), which has created a unique food culture, and nurtured a unique academic area of dietary medicine (藥膳食料學). This study aimed to develop a desirable dietary life-style based on the oriental dietary medicine theorem originated from the schema of four qi as well as five flavors of foods (四氣五味), originated from the yin-yang and five phase theory based on a clear understanding of a modern point of view, and experimental analysis of nutrients and dietary effects of clear heat effect materials. This study can promote more healthy life-styles and prevent adult diseases by following oriental dietary medicine theory. We should develop a Yack-sun theory and dietary culture that is suitable for physical and genetic health.
