The dairy industry, as part of the broader agricultural sector, is classified as a basic industry to the Korea economy. Basic industries provide income to a region by producing an output, purchasing production inputs, services and labor. An integrated, multidisciplinary approach for the next generation of dairy products with added health benefits represent the direct economic contribution. The commercialization of "nutritional" functional foods can only be successful if the consumer is confident in the scientific validity of the claims. Modern biotechnologies such as genomics, genetic expression and biomarkers of health performance suggested to whole dairy products, such as fluid milk, butter, cheese, ice cream and frozen dessert products (German, 1999). The following definition makes the point that dairy products can provide a nutritional value beyond the basic nutritional requirements: 1) The dairy industry has the opportunity to improve the health and well-being of its customers and/or to reduce their risk of disease through dairy products with added activities. 2) Functional dairy products are those that can be demonstrated to benefit target functions in the body in a way that improves the state of health and /or reduces the risk of disease. They are food products that are consumed as part of a normal diet rather than pills or supplements. 3) Dairy products based on functionality will need to link the scientific basis of such functionality to the communication of its benefit to the general public. 4) Both the efficacy and the safety of the food components with health benefits will require evidence based on the measurement of scientific biomarkers relevant to their biological responses and health end points. 5) Sound evidence from human studies based on intermediate health end points using accepted biomarkers will provide the basis for promotional messages divided into two categories-enhanced function and reduced risk of disease. 6) Success in solving key scientific and technological challenges will only be achieved by interdisciplinary research programs to exploit the scientific concepts in functional dairy science.

The labeling for functionality of food or food components are recognized globally and are essential for the growth of dairy product industry. To expand the functional claims of dairy product especially fermented milk product, the regulations restricting the labeling of functionality should be amended as soon as possible. The labeling regulations of functionality and efficacy for processed and functional foods in related Acts and subordinated statues such as definition, scope of claims, etc. were reviewed and the problems existed in the system were identified. The definition and classification of efficacy for processed food in Food Sanitation Act were analyzed to revise the labeling regulation of dairy product. A draft of amended labeling regulation for the functionality of dairy product is proposed, which provides consumers with appropriate information of beneficial effects on health purpose for human body structure and function. In order to develop the dairy products and related industries, these contents should be considered when the annexed Table 14 in the Enforcement Rule of the Processing of Livestock Products Act is amended.

Due to the rise of customer's alertness about fresh foods to health, in the past few years, the consumption of fresh food has increased sturdily. The use of gas scavengers is the most appropriate packaging technologies for fresh, fresh-cut produces and in ready to eat products. The gas absorber/scavenger has ability to protect or stabilize the wanted properties and shelf life of food. The success of gas absorbers in food depends on many parameters such as types of foods, storage temperature, relative humidity, initial gas concentration, and the characteristics of package materials. In this review article, we focus on the most recent research trends in gas scavenging systems used in food packaging, future trends. Intense research from industry and engineers remains important to the development of gas scavenging package that fulfill consumer requirements, enhance product quality, and offer environmentally friendly design and cost-effective application.

The purpose of this study was to investigate the perceptions, intake levels and information needs of elementary school students on artificial food colorants in order to provide better understanding and proper dietary education to these students. From May to June 2010, a survey was conducted from 315 elementary school students at fifth and sixth grade level who were living in Seoul. The questionnaire was distributed by 14 elementary school teachers to their classroom students. The results showed that food safety was regarded as the most important factor in purchasing food items, and artificial food colorants were the most interested among various food additives. Although there was a lack of general knowledge and the students' estimated intake levels of artificial food colorants from processed foods were comparatively low, most (82.7%) believed that artificial food colorants were dangerous for health. The information they wanted to know most was the safety, necessity, and function of artificial food colorants, in order. Above results suggested the necessity of providing accurate information on artificial food colorants to elementary school students possibly by developing educational materials which can improve the perceptions on artificial food colorants and encourage a safe dietary life.

Black vinegar has been traditionally used for supplemental flavoring on food, and commercialized beverages. Here, to investigate the effects on in vivo anti-obesity complications of black vinegar produced with herbal extracts, we evaluated on the biochemical effects of high-fat diet (HFD) induced mice compared to control fed ones. After a 84-day experiment HFD mice had higher (P < 0.05) weight gains, relative abdominal-fat pads, blood glucose level, serum/liver lipids, and serum nephron indices. Continuous oral treatment of three different concentration of herbal black vinegar (HBV; stock, 2-fold, and 4-fold diluted solution) to HFD mice showed that HBV reduced marked obesity (fat depositions, adipocyte hypertrophy), hyperglycemia, hyperlipidemia (serum total cholesterol, triglyceride, LDL-cholesterol levels), enhanced liver function (AST/ALT), and kidney function (BUN, creatine levels), respectively. Thus, HBV is expected to serve as an efficient and functional supplemental ingredients or food for the alleviation of obesity syndrome.

Objectives: This study examined the effects of nutrition education focused on personalized daily energy requirement and food units using Food Exchange System on anthropometric, biochemical characteristics, nutrition knowledge, dietary attitude and nutrient intakes for overweight and obese in a public health center. Methods: The subjects were 60 overweight/obese women based on BMI (educated 30 vs. non-educated 30, 50~64 years). Educated group was provided individual and/or group lessons (40 min/lesson/week, 5 week), 'Introduction: obese & health', '6 nutrients and 6 food groups', 'My obesity & daily needed energy', 'Meal planning for personalized daily energy and food units using Food Exchange Systems', and 'Smart food choices'. After education, we examined the differences in anthropometric/biochemical characteristics, nutrition knowledge, dietary attitude and nutrient intakes between educated group and non-educated group. Results: After nutrition education, in the educated group, there were improvements on anthropometric/biochemical characteristics, nutrition knowledge, dietary attitude and nutrient intakes in the educated group compared to the non-educated group. We observed a decrease in the mean weight, total cholesterol (TC) and the incidence of overweight/obesity and hypercholesterolemia and an increase in the mean lean body mass. The scores of nutrition knowledge, 'Function of carbohydrate, protein, vitamin, mineral' and 'Food Sources of fat, vitamin, mineral' were increased. The scores of dietary attitudes, 'Taking a joyful meal, a leisurely meal, a balanced meal, a meal with sufficient vegetables, a meal with diversity, a meal with spicy foods, a meal with overeating' were increased. The intakes of energy, carbohydrate, fat, protein, vitamin A, thiamin, Zn and cholesterol were decreased. The scores of INQ, protein, vitamin A, vitamin C, thiamin, riboflavin, vitamin B6, folate, Ca, P, Fe, Zn were increased. Conclusions: The nutrition education focused on personalized daily energy requirement and food exchange unit using Food Exchange System for overweight and obese may improve food behavior, dietary intakes and symptoms of overweight and obese, even in a community health center.

Various Korean healthy foods containing Deoduk were developed and standardized recipe. Sensory evaluations of Koreans and foreigners for these developed foods were performed by using the 5-point hedonic scale. The results of the sensory test on foods containing Deoduk were as follows: Deoduk bap (2.90~3.91), Deoduk seolgidduk (3.19~4.40), Deoduk gangjeong (3.00~4.60), riasted Deoduk with red pepper paste (2.73~4.20), Deoduk pine nut juice salad (2.40~3.96), and Seopsansam (3.91~3.81). Deoduk seolgidduk, developed by using a recipe for Sansambyeong which in a Chosun dynasty cook-book, was highly preferred by Africans, Japanese, and Koreans. In particular, all foreigners except Southeast Asians liked Deoduk gangjeong, and both Koreans and foreigners liked Seopsansam. Foreigners' experience of eating foods containing Deoduk was high at 'No' (68.9%), whereas Japanese (60.0%) had previous experience. Exactly 91.6% of Koreans responded 'Yes' to the question of whether or not Deoduk food is good for health, whereas the proportion of foreign respondents who said 'Yes' was 43.2%, 'No' was 5.4%, and 'I don't know' was 51.4%. Deoduk seolgidduk was preferred by Japanese, and most foreigners preferred Deoduk gangjeong and Seopsansam. Therefore, Deoduk could be developed as a healthy food for globalization of Korean food. However, as foreigners' awareness of Deoduk is low, we must positively promote the health function of traditional food ingredients and develop various menus suitable forforeigners' tastes for the globalization of Korean food.

Numerous investigators have studied various activities of natural products and have found that they have not only nutritional effects, but also beneficial properties to cure various diseases and to maintain good health. Job's Tear(Yul-Moo) is a grass crop that has long been used in traditional medicine and as a nourishing food. Although its mechanism of action remains unclear, Job's Tear has been reported to exhibit anti-inflammatory, stomachic, anti-allergic, and anti-spastic effects and has been used in China for the treatment of warts, rheumatism, and neuralgia. Previous results in our laboratory demonstrated that the ethanol extract and the water extract of Job's Tear exerted an immune regulatory function on mice cells in vitro. The present study was performed to investigate the ex vivo effect of Job's Tear on immune function. Seven to eight weeks old mice(Balb/c) were fed chow diet ad libitum and water extract of Job's Tear was administered orally every other day for four weeks at two different concentrations(50 and 500mg/kg B.W.). Splenocytes proliferation with mitogen stimulation with Con A and LPS was enhanced at 50 mg/kg B.W. of Job's Tear compared to those of the control group. The results of this ex vivo study showed that proliferation of splenocytes and macrophage activation were seen in the mice orally administrated 50 mg/kg B.W. of Job's Tear water extracts. In conclusion, this study suggests that Job's Tear extracts may enhance immune function by regulating splenocyte proliferation and the cytokine prodution capacity of activated macrophages in mice.
