The present invention relates to a method for preparing a fermented ginseng concentrate. The method first involves subjecting ginseng to an extraction with a solvent to obtain a ginseng extract. Next, pectinase and beta-galactosidase are added to the ginseng extract under conditions effective to ferment the ginseng extract. The fermented extract is then concentrated to produce a fermented ginseng concentrate. The method may further involve drying the fermented ginseng concentrate to obtain fermented ginseng powder.
