Background : Korea ginseng root has been traditionally used as a tonic as it is stated to have the capacity to normalize body functions and strengthen systems that are caused by various stresses. So, ginseng is functional food with the functionalities certified by Korea Food and Drug Administration. But, there are not many different products using ginseng. This study was conducted to develop the new ginseng beverage product using emulsify process. Methods and Results : White ginseng and red ginseng, 4-years old, prepared were ground to 60 ± 5 mesh using a grinder (Cyclotec 1093, POSS Co., Swiss). Emulsion with white ginseng powder (WGP) and lipid phase (canola oil) were prepared using the modified method (Yun & Hong, 2007). Oil-in water emulsions were made by homogenizing (5,000 – 15,000 rpm, 20 – 60 min), and then were analysed ginsenosides content, protein and polysaccharide content. The higher the speed of homogenizer and the longer the time, the higher the ginsenosides extraction rate. On emulsifying for 60 min at 12,000 rpm, ginsenosides were extracted by more than 95%. Red ginseng powder (RGP) was superior to WGP in emulsified activity, but WGP was superior to RGP in emulsion stabilizing. Comparing components of WGP and RGP emulsion, RGP had more ginsenosides content than WGP, and less polysaccharides content. When mixing WGP and RGP with a ratio of 90 : 10 – 70 : 30, the emulsion have excellent emulsifying and stabilizing. Conclusion : Thus, WGP and RGP are the same ginseng, but they have different physiological characteristics because their manufacturing process is different. These studies may provide new product development for effective utilization of ginseng by using excellent emulsion stabilizing of WGP and emulsifying of RGP.
