This work has been conducted as a part to set up the regulations and the scientific evaluation systems for the functional dairy products with health claims in Korea. Toward this end, current regulations, requirements, and all kinds of provisions related to the functional dairy products overseas were taken into accounts and feasible recommendations of new initiatives on the current regulations as well. By doing so, not only protecting hopefully the innocent consumers from the false labeling statements and fake advertisements, but also eventually to revitalize the stagnated domestic dairy industries. Currently, functional daily products are simply regarded as "Dietary Supplements" in the United States, and subjected to the regulations under the Dietary Supplement Health and Education Act, established m 1994. Manufacturers and sales distributors should notify their products to the FDA, which is in charge of the dietary supplements on nutrition and labeling, in advance when they start marketing a new dietary ingredient or any foods containing it in the States. For EU countries, there exists keen interests about the functional food products between the member countries of the European Union even though the products are categorized into "Food Supplements" similar to those in the United States. Therefore, they maintain a cautious attitude in applying the health claims to the functional food products. On the other hand, under the Japanese health food system, functional foods are qualified to the functional health foods in terms of legal status as long as any traditional foods can meet the legal standards in its effectiveness, safety as well as quality, along with significant scientific evidences related to the products, thus categorized into "Foods for Specified Health Uses and "Foods with Nutrient Function Claims". Through this study, we may have some expectations and potential utilizations as follows: Legal regulations of dietary supplements especially for the dairy products will be implemented by the outcomes of this research and proposed a tentative amendment of functional ingredients for the sake of consumer protection from the false advertisements and overstatement labeling. Current regulations on the animal foods processing and advertisements will be amended and supplemented in order to revitalize the current downturn dairy sales and to harmonize the international Codex recommendations. The results obtained from this study will make the consumers a wise selection of the dairy products with health claims and be utilized for consumer education and advertisement of the functional products as well.

In order to create a worker-friendly environment for institutional foodservice, facilities operating with a dry kitchen system have been recommended. This study was designed to compare the work safety and work environment of foodservice between wet and dry kitchen systems. Data were obtained using questionnaires with a target group of 303 staff at 57 foodservice operations. Dry kitchen facilities were constructed after 2006, which had a higher construction cost and more finishing floors with anti-slip tiles, and in which employees more wore non-slip footwear than wet kitchen (76.7%). The kitchen temperature and muscular pain were the most frequently reported employees' discomfort factors in the two systems, and, in the wet kitchen, "noise of kitchen" was also frequently reported as a discomfort. Dietitian and employees rated the less slippery and slip related incidents in dry kitchens than those of wet kitchen. Fryer area, ware-washing area, and plate waste table were the slippery areas and the causes were different between the functional areas. The risk for current leakage was rated significantly higher in wet kitchens by dietitians. In addition, the ware-washing area was found to be where employees felt the highest risk of electrical shock. Muscular pain (72.2%), arthritis (39.1%), hard-of-hearing (46.6%) and psychological stress (47.0%) were experienced by employees more than once a month, particularly in the wet kitchen. In conclusion, the dry kitchen system was found to be more efficient for food and work safety because of its superior design and well managed practices.

Anti-angiogenesis therapy is one of the most promising strategies for the treatment of cancer. We investigated the anti-angiogenesis activity of an extract from the ark shell Scapharca subcrenata and attempted to purify the active compounds. The crude extract of the ark shell inhibited the proliferation of human vein endothelial cells (HUVEC-1) and tube formation by human dermal microvascular endothelial cells (HMEC-1). The methanol extract of the viscera of the ark shell showed activity. The ark shell extract acts as an angiogenesis inhibitor and could be developed further as a health substance, functional food, and anticancer agent.

The objective of this study was to evaluate the nutritional content of bullfrog meat from different parts of the animal, including fore-chest, thigh and calf. Bullfrog meat was found to be a rich source of proteins, essential amino acids and minerals, but with a low fat content, compared with other aquatic meat products. There was no significant difference (p>0.05) between thigh and calf in mineral content (K, P, Na, Mg, Ca, Zn, Fe, Cu, and Mn), but the contents of K, P, and Mg were higher in thigh and calf than in the fore-chest (p<0.05). The salt-soluble, water-soluble and insoluble protein bands in sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) electrophoresis, from fore-chest, thigh and calf were similar, with the most abundant bands being 35 kDa (salt-soluble protein), 35-48 kDa (water-soluble protein) and 48 kDa (insoluble protein). The results showed that the insoluble protein content in the fore-chest meat was higher than that in the thigh meat and calf meat, but the salt-soluble protein fraction was the most abundant in thigh meat. These results showed that the nutrients in different parts of bullfrog meat were different.

본 연구에서는 재래생강과 중국종자생강 간의 증숙 시간별 총 페놀화합물, 총 플라보노이드, ABTS 및 DPPH 라디칼 소거능, gingerol, shogaol 함량을 비교 분석하였다. 총 플라보노이드와 총 페놀 화합물, ABTS radical 소거능의 경우 대체적으로 증숙 6시간에서 가장 높은 함량을 나타내다가 그 이상으로 증숙할수록 오히려 감소하는 경향을 보였으며, 생강 중에서는 재래생강인 WO-2가 가장 높게 나타났다. DPPH 라디칼 소거능은 증숙 시간별로 유의미한 차이가 없었다. 생강의 gingerol 함량은 대조군에서 WO-2가 1,351 mg/kg으로 가장 높은 함량을 나타냈다. 증숙 시간에 비례하여 gingerol의 함량은 감소하고, shogaol의 함량은 증가하였는데 증숙 8시간에서 WO-2가 생강 중에서도 가장 높았으며, 또한 종자별로도 재래생강이 중국 종자생강보다 shogaol 함량이 높은 것으로 나타났다. 본 연구결과 재래생강이 중국종자생강보다 기능성 함량이 높음을 확인하였으며 증숙 처리된 재래생강을 활용하여 다양한 식품을 개발할 수 있을 것으로 판단된다.

본 연구는 Atractylodes macrocepala KOIDZ.의 급성 경구 독성을 평가하기 위하여 SD계 Rat를 이용하여 농도별 열수 추출물을 투여하고 체중변화, 이상반응, 장기무게변화, 혈액학적 이상반응, 조직병리학적 이상반응 등을 측정하였다. Atractylodes macrocepala KOIDZ.를 투여한 실험군에서 비교적 낮은 농도에서 체중의 감소가 관찰되었으나, 이상반응이나 장기무게에 있어 유의성 있는 변화는 관찰되지 않았다. 혈액학적 지표에 있어서도 비교적 낮은 농도에서 WBC 및 AST의 증가가 관찰되었다. 조직병리학적 소견에서 일부 간조직의 지방변성이 관찰되어 간독성과 간세포에 미치는 영향에 대한 연구가 필요할 것으로 판단된다. 이와 같은 연구의 결과를 종합해 볼 때 백출이 경구투여에 있어 비교적 안전한 물질인 것으로 판단할 수 있다. 그러나 단회 경구투여 급성독성시험만으로 천연물 생약에 대한 독성 유무를 판단하기에는 일정부분 제약이 있으므로, 추가적으로 2주(또는 4주) 반복 경구투여 독성시험 및 13주 반복 경구투여 독성시험 그리고 유전독성에 대한 연구들이 순차적으로 수행되어야 하며, 이를 통하여 백출에 대한 체계적인 독성정보를 구축함으로써 보다 정확하고 과학적 근거에 입각한 안전성 자료가 확보될 수 있을 것으로 기대한다.

Traditional cuisine reflects cooking traditions shaped by political, economic, social, cultural, and environmental conditions characterized by authenticity and uniqueness. Traditional food is not only a part of our cultural heritage but also a knowledge resource. Application of food science and technology in Korean traditional foods was reviewed from six points of view, including food preservation, fermentation, changes in food materials, utilization of food functionality, and packaging and development of cooking appliances. Books from disparate times were chosen in order to cover a wide range of materials from the past to the present. Food preservation and fermentation techniques were applied to various food materials. Combination of science and skills contributes to the accessibility of diverse food materials and better quality foods. Koreans use assorted and resilient plants, which have an abundance of functional substances such as food materials. Among cooking appliances, microwave oven and refrigerator are the most innovative products with huge influences on food eating patterns as well as lifestyle. Packaging effectively reduces post-harvest preservation losses, and better packaging has technical improvements for storage and distribution. Kimchi was chosen as an example in order to study technology from the past to the present. Availability of Kimchi cabbage, enrichment of functional ingredients, identification of useful microbial species, standardization of recipe for commercialization, prevention of texture softening, introduction of salted Kimchi cabbage and Kimchi refrigerators, and packaging were reviewed. The future of traditional foods in the market will be competitive. First, traditional foods market should be maintained to protect the diversity of food materials. Secondly, tailored foods for individuals should be considered using foods with functional properties. Information on health benefits would provide insights into health and traditional food products. Third, speedy transfer of new technology to the traditional food industry is needed to ensure food quality production and new opportunities in the market. Fourth, safety of traditional foods should be ensured without sacrificing the essential characteristics of culturally important foods. Improvement of logistics, distribution, and facility should be carried out. As demand for convenience foods increases, traditional foods should be developed into products.

The purpose of this study is to show probability of alternate food by using edible insects through the reports (Edible insects: Future prospects for food and feed security) edited by WFO (World Food Organization). We were carried out to develop the functional meat new product using Mealworm (Tenebrio molitor lavare) and Chicken breast. People's interest to the healthy, low-calories food is growing up, the Foodservice industry is developing and making Functional food, which helps to a sale strategy. Insects have played an important role as human food throughout history, especially in Africa, Asia and Latin America. A rapid increase in the human population is expected in the second half of the 21 century, which will lead to lower availability of food, especially animal protein As the problem of food supply and demand has come to the fore with climate change, Food and Agriculture Organization of the United Nations (FAO) has noticed edible insects as future food resources in order to prepare against the shortage of protein source. Recently consumers, especially patients have doubts about safety of raw materials for food. To overcome these limitations, I propose an enteral nutrition formula using edible insects as a raw material.
