Abstract

To find up using of more efficient white ginseng, white ginseng was dried on various temperature (70, 80, 90,100, 110, 120, 130 and $140^{\circ}C$) with far-infrared drier and analyzed the composition of ginsenoside, carbohydrate, organic acid content and color. The type of ginseng shape was sliced and dried main and fine root, separately. As heating temperature increased, total ginsenoside content increased on main root, its content was the highest at $130^{\circ}C$, while decreased on fine root. Soluble carbohydrate content was the highest at $70^{\circ}C$ both on main and fine root. Increase of Re, Rc and Rb2 content was increased more high at $130^{\circ}C$, especially. But on fine root, content of Rg1, Rg3, Rf and Rb3 was increased and Re, Rc,Rb1 and Rb2 were decreased by the increased of temperature. As heating temperature increased, lightness of both main and fine root were decreased. Redness and yellowness of both main and fine root was increased to $120^{\circ}C$ and $100^{\circ}C$, respectively and decreased over this temperature.

수삼을 주근 및 세근으로 분리하여 원적외선건조기를 이용하여 건조온도(70, 80, 90, 100, 110, 120, 130 및 $140^{\circ}C$)에 따라 건조한 후, 사포닌, 당, 유기산 및 색도를 분석하였다. 건조한 주근의 총사포닌 함량은 건조온도가 높을수록 미량 증가하여 $130^{\circ}C$에서 가장 높았고 세근에서는 온도가 증가할수록 감소하였다. 세근에서 온도가 증가할수록 급격하게 감소한 ginsenoside는 Re, Rc, Rb1 및 Rb2 이었고 Rg1, Rg3, Rf 및 Rb3는 미량씩 증가하였다. 가용성 당은 주근, 세근 모두 $70^{\circ}C$에서 가장 많이 용출되었고, 유기산 함량은 주근 세근 모두 $120^{\circ}C$에서 가장 많은 함량을 보였다. 건조온도에 따른 색도는 온도가 증가할수록 밝기는 주근 세근 모두 감소하였고 적색도는 온도가 증가할수록 높아져서 $120^{\circ}C$에서 가장 높았고 황색도는 $100^{\circ}C$에서 가장 높았으며 그 이상의 온도에서는 감소하는 경향이었다. 따라서 수삼 건조 시 건조온도에 따라 사포닌 구성함량 변화의 차이를 보임으로서 백삼의 이용목적에 맞게 수삼 건조 시 온도, 건조 형태 및 주근과 세근을 분리하여 건조하는 방법을 이용하는 것이 바람직할 것으로 생각된다.
