The purpose of this study was to analyze the ingredients and characteristics of main functional drinks on the market. Functional drinks available on market were categorized into sports drinks, dietary fiber drinks, flavor-blended drinks, special nutrition drinks, and drinks for hang-overs. The results were: 1. Sports drinks contained water, inorganic ion, electrolytes, carbohydrate and vitamins as general ingredients, and red ginseng, oligosaccharides or octacosanol as special ingredients. Sports drink was an isotonic solution having similar osmolarity to body fluid and included more inorganic ion and electrolyte than other functional drinks. Special ingredients contained in the sports drinks played important roles in preventing fatigue, constipation and muscular pain, and in improving basal metabolic rate, vitality, and muscular strength. 2. Dietary fiber drinks contained different fibers such as polydextrose, dextrine and soybean oligosaccharides. Common characteristics of these fibers were dietary and preventive effects on diabetes and constipation due to their low calorie and indigestive character. Inorganic ion and electrolyte were included a little and were not important compared to sports drinks. Sweetness of fiber drinks was different from that of sport drinks, but not different from flavor-blended drinks. 3. In flavor-blended drinks, physiological and nutritional functions of vitamin, amino acid, and special ingredients were important. Amino acids and vitamins contained in the flavor-blended drinks had various functional effects such as anti-fatigue and energy enhancement. Special ingredients contained in the flavor-blended drinks were honey, ganoderma lucidum and royal jelly. Chinese medicine or Korean traditional edible materials might be possible to be used as special ingredients. 4. Functions of special nutritional drinks and drink for hang-overs were shown to be well-defined than other drinks. The ingredients of special drinks were protein, fat, carbohydrate, vitamins and mineral that are essential nutrients. Therefore special drinks had effects for food supplement and foot substitution. Drinks for hang-overs contained glumate, honey, ganoderma lucidum, royal jelly, vitamin B1, B2 and C. Glumate that is a main ingredient has a function that can resolve alcohol. It could be concluded that additions of natural or synthetic materials suitable to the aim of developing products as well as ingredients contained in drinks on market are desirable to be added.
