Abstract

The effects of far infrared irradiation (FIR) on protopanaxatriol and propanaxadiol ginsenoside were investigated with ultrafine powdered red ginseng and compared with untreated sample. The study showed that FIR treatment increased the Rf, Rg2, and Rh1 production in a temperature dependent manner, but Rg1 and Re decreased with temperature. Similarly, Rg3, Rk1 and Rg5 increased with temperature. The maximum increase was observed at 215°C with 2.09, 4.67, 17.23 and 18.57 times for Rb3, Rg3, Rk1 and Rg5 respectively. Likewise, Rd and Rc also increased gradually with temperature. However, Rb1 showed negative effects with temperature, showing decreased activities with increasing temperature. Overall, this research is expected to be helpful in enhancing the bioactive ginsenoside in ultrafine powdered red ginseng by optimizing the FIR conditions.
