This study was done for the determination of ginsenosides contents of Korean ginseng and ginseng products as well as the development of analytical method for ginsenosides. It is known that perfect segregation of ginsenoside Rg and Re is not easy, but in this study almost perfect segregation can be possible by the control of concentration between acetonitrile and water. Among Korean ginseng, ginseng powdered tea and red ginseng powdered tea, the highest ginsenosides content of sum of each 7 kind o ginsenoside was found in red ginseng powdered tae as 23,211${\mu}g$ per 1g/dw The ginsenoside content of ginseng powdered tea was lower than red ginseng powdered tea as 15,217${\mu}g$ per 1g/dw Total ginsenoside content in the root of ginseng was 29,268${\mu}g$ per 1/dw Each amount of ginsenoside contained in ginseng root was in the order of Rb1, Rg1, and Rc. It was shown that there was difference in constitutional element of ginsenosides in ginseng powdered tea and ginseng root.

This study was conducted to investigate the water vapor permeability of packaging film, Al- foil laminated paper, and sorption properties of dehydrated and powdered foods. The results are as fellows. 1. Absorption rate of each products was greately affeoted by physicochemical properties of foods rather than initial moisture contents of the products. 2. The absorption rate of each products were in the order of freeze dried coffee, spray dried coffee, freeze drie4 ginseng extract, spray dried ginseng extract, ginger tea, black tea, citrus juice Powder and ssang wha tea. 3. Most of the products such as freeze dried coffee, spray dried coffee, freeze dried ginseng extract, ginger tea and black tea have shorter than a month of shelf life. 4. The stability of the products were greatly affected by its desorption properties than the degree of desorption of moisture. 5. Water vapor permeability of packaging materials which are laminated Al-foil with polythylene and glassin paper were mainly affected of thickness of Al-foil and polyethylene.

This study was performed to investigate the kinds of health food advertised and sold through media like printed matter, TV broadcasting or internet. It was found that fifty three percent of the health food was circulated through internet, 27% through printed matter, 9% through TV Broadcasting. When the health foods was classified, the proportion of special purpose nutritious foods was 36.1%, health aid foods 33.9%, uncooked powdered foods 18.5%, functional foods for health 4.9%, Ginseng products 3.9%, and tea 0.9%. The special purpose nutritious foods was composed of 59% of nutrition supplementary foods, 24% of dietary fiber foods, 9% of weaning foods, 7% of milk formula and 2% of HCA. Vegetable extracts occupied 21.1% of health aid foods, yeast 7.5%, mushroom extracts 7.0%, chitosan 6.2%, aloe 5.3%. Dried powdered type health food occupied the highest proportion. The other type were capsule(18.8%), tablet(18.1%), and liquid type(16.4%). When the health food was classified with health claim, the proportion of "nutrition supplementation" was the highest (23.9%), "diet" 14.9%, "ergogenic"(18.8%), "promoting bowel movement" 7.8%, "growth" 5.7%, "regulation of blood sugar" 4.5%, "improving of immunity"(2.4%) and anti-aging effect(2.4%).
