With increasing interest in the health and safety of food served in restaurants, more emphasis is being placed on the importance of health and food. As a result, Yaksun cuisine with new added effects and image is becoming more popular as a way to improve people's health. This study analyzed the effects of selection attributes relating to Yaksun cuisine on customer satisfaction and intention to maintain relationship in order to understand various needs of consumers as they relate to health food. The results showed that, among selection attributes of Yaksun cuisine, price, safety, and health were found to have significant effects on customer satisfaction; however, the effect of quality on satisfaction was not verified. Moreover, while the effect of safety and health of Yaksun cuisine on the intention to maintain relationship was found to be significant, the effects of quality and price on the intention to maintain relationship were not verified. These findings suggest that consumers believe Yaksun cuisine is more beneficial for health than general food and trust the origin label, hygiene, and safety of ingredients in Yaksun cuisine. Therefore, the results of this study suggests providing opportunities for consumers to experience diverse tastes in Yaksun cuisine and that development and promotion of different recipes using Yaksun ingredients will help reinforce competitiveness of Yaksun cuisine in the market and increase sales.

Consumers want to get healthful food which guarantee the aging control, anti-tumor, immunity-reinforcement, obesity prevention, beauty, prevention of adult disease and well-being. Because they want natural foods without food additives and environmental pollution which were used for convenience, we should develop the various food to guarantee the safety, wholesomeness and convenience. And so, we must study and identify basically the functionality and sanitation in foods to use practically. The companies should develop new products and corporate with universities and government. Because there are much more food informations, people believe unidentified information and continue wrong behavior such as food faddism. Consequently consumers should choose wisely their foods in consideration of their health, time, money and purpose.

BACKGROUND/OBJECTIVES: The objective of this study was to determine dysphagia risk among community-dwelling elderly people living at home. We also examined the impact of socio-demographic variables on dysphagia risk as well as the relationship between dysphagia risk and dietary characteristics. SUBJECTS/METHODS: The study sample included 568 community-dwelling individuals, aged 65 years and above, who were living independently in their own home in Seoul, Gyeonggi, or Gwangju in South Korea. We used a dysphagia risk assessment scale to screen for dysphagia risk and the Mini nutritional assessment to evaluate the nutritional status. Associations between dysphagia risk and other variables were assessed using logistic regression analysis. RESULTS: Of the 568 subjects, 350 (61.6%) were classified into the dysphagia risk group (DR) and 218 (38.4%) were classified into the normal group (non-DR). Being female (odds ratio (OR) = 1.82, 95% confidence interval (CI) = 1.28-2.59), being 75 years and older (OR = 2.40, 95% CI = 1.69-3.42), having a lower education level (OR = 2.29, 95% CI = 1.33-3.97), and having a lower perceived economic status (OR = 2.18, 95% CI = 1.32-3.60) were more frequently observed with dysphagia risk compared to those who did not have such characteristics. Lowered mastication ability (OR = 14.40, 95% CI = 4.43-46.95), being at risk of malnutrition or malnourished (OR = 2.72, 95% CI = 1.75-4.23), lowered appetite (OR = 3.27, 95% CI = 2.16-4.93), and decreased food intake (OR = 2.95, 95% CI = 1.83-4.78) were observed more frequently in the DR group than in the non-DR group when adjusting for potential confounding factors. CONCLUSIONS: It is necessary to develop and apply integrated programs to improve the dietary habits and nutritional status of elderly individuals at risk for dysphagia, especially for women aged 75 years or older with lower educational and economic levels.

The aim of this study was to investigate food culture represented by the grain yard, water well, kitchen, and meat storage space which were depicted in the mural painting of An-Ak tomb No. 3. The mural paintings of An-Ak tomb No. 3 were compared with those of ancient Chinese tombs before the 4th century in order to understand their characteristics. Above all, the tomb murals describe the form and function of the stove (buttumak) as well as the cuisine using the cauldron (sot) and steamer (siru) in a very interesting manner. The meat storage space of An-Ak tomb No. 3 shows whole carcasses of animals such as roe deer, dog, and pig. However, Chinese murals show that while small animals such as soft-shelled turtle, fish, chicken, duck, pheasant, rabbit, etc. were stored as whole carcasses without being cut into pieces, large animals such as cows and pigs were slaughtered and each piece of their carcasses such as the head, thigh, meat loaf, and cardiopulmonary part was separately depicted. These tomb murals vividly describe the food culture of Koguryo and China before the 4th century.

During the past decade, functional foods and nutraceuticals have emerged as a major consumer-driven trend, serving the desire of aging populations to exercise greater control over health, delaying aging, prevent disease and enhance well-being and performance. On a global basis, retail sales of functional food were worth an estimated USD 1,501 billion in 2001. The market for functional food in Korea has increased in the last three years above 10%. Especially value sales rose by over 30% between 1999 and 2001, and are worth around 12,000 billion won in 2001. To regulate functional food represented a rapidly growing market in Korea a new act 'Functional Health Food Act' was announced officially in 2002. The type of functional milk product in Korea market is conventional food containing various functional ingredient. To promote functional food market in milk product sector the introduction of functional and health claim should be taken into account in the future in Korea.

Rheum undulatum and Rheum palmatum have been widely used as food material as well as medicinal ingredients for their therapeutic effects in oriental countries. Many kinds of herbs are being used in the manufacture of functional foods. The objective of this study was to determine polyphenol content, superoxide dismutase (SOD)-like activity, tyrosinase activity, and electron donating ability of R. undulatum and R. palmatum. Total polyphenol content were most effective in 50 and 100% ethanol extracts from R. undulatum and R. palmatum. SOD-like activities of R. undulatum extracts were higher than those of R. palmatum extracts, and water extracts of samples were highest. EDAs of R. undulatum extracts were higher (26.76-44.46%) than those of R. palmatum extracts, while those of both extracts were lower than 1.0 and 0.1% L-ascorbate. And these suggest that the extracts of R. undulatum and R. palmatum can be used as a material in functional food.

In order to investigate if nutrition-related TV programs give the public correct and useful imformation, 26 producers(PD) having worked for any one of the nutirtion-related TV programs were surveyed by using questionnaire on the attitudes toward seeking an expert's advice about the issues and the panelist's constitution of one typical nutrition-related TV show program broadcasted during the last 5 years was analyzed. The most important reason for selecting the nutrition-related issues was to satisfy the interests and demands of audiences. Both being motivated by food-related accidents and to educate people for the health promotion were the second ones. In the process of nutrition-related program production, 53.9% of PDs always requested expert's advice, while 46.1% occasionally did. Professors in food and nutrition were regarded as the most proper advisor. Dietitians, physicians and physicians of Chinese medicine wer the next in order. The similar pattern were shown in the rankd of specialists actually invited as panelists to the program. Both the speciality and being well-known were less positive and favorable for participating in the program compared to experts in other areas. The number of programs about food and nutrition broadcasted on the TV show during 1993-1997(July) was 361(about 30%). The total of 1,043 specialists appeared, 2.9 persons per program on the average. Of these, only 12.9% were professors in food and nutrition as well as dietitians. The largest(20.2%) was physicians or medical professors, and 13.6% cooks and 12.6% physicians of Chinese medicine. Of 361 programs 45 were thought to be undesirable on the panelist constitution. Particualrly in 19 programs, where nutritionists were not invited, physicians or physicians of Chinese medicine explained diet therapy, food, nutrient or dietary habit.

The study of health promoting and disease preventing compounds in food or by themselves, so called nutraceuticals or functional foods, has become a major field of research in food science. Natural flavor compounds are usually present in food, essential oils, spices, and herbs. These compounds can produce aroma, not only by themselves, but also in combination with other compounds. Today, however, greater interest is being paid to the health promoting properties of natural flavor substances rather than their flavoring properties. In fact, a number of naturally occurring flavor compounds that possess health promoting and disease preventing properties have been extensively studied and identified. The beneficial properties of natural volatile flavor compounds as well as non-volatile substances in spices and herbs discussed in this review include antioxidant, anticarcinogenic, anti-inflammatory, and immune enhancing activities.
