Abstract

This study was conducted to investigate the effect of moisture content and pressure on extraction yield, crude saponins and ginsenoside contents of puffed Korean ginseng. Puffed ginsengs showed relatively higher extraction yield (50.0~62.1%) and amounts of crude saponins (19.6~48.8 mg/g ginseng) than no-puffed ginseng (37.6±0.8% and 11.0±1.0 mg/g ginseng), respectively. The highest extraction yield and amounts of crude saponins were obtained in 8.0% moisture content sample puffed at 10 kgf/cm2. In HPLC analysis, amounts of measured major ginsenosides (Rb1, Rb2, Rc, Rd, Re, and Rg1) decreased with increasing puffing pressure, yet contents of almost all major ginsenosides were higher than control (no-puffed). On the other hand, ginsenoside Rg3 were produced after puffing suggesting that chemical structure of some ginsenosides might be altered during the puffing process. These results indicate that puffing can increase the extraction yield and crude saponin contents and it could influence the ginsenoside composition.
