Abstract

The extraction conditions for the production of red ginseng polysaccharide were proposed. The crude fiber content of red ginseng marc (RGM) (15.3%) was much higher than that of white ginseng (WG) (2.1%) and red ginseng (RG) (0.5%). Thus, RGM was selected as the raw material for polysaccharide production. The correlation between the particle size of RGM and the polysaccharide extraction was investigated with a correlation analysis using the SPSS package. The two parameters were found to have a significant correlation (p＜0.01). The polysaccharide extraction increased as the particle size of RGM decreased. The optimal concentration of RGM was 6.66% (w/v). The extraction yield increased as both the extraction temperature and the extraction time increased. Finally, the extraction temperature and time were selected as 85℃ and 5 hrs, respectively. Consequently, the extraction conditions for polysaccharide production were optimized and statistically confirmed.
