The purpose of this study was to compare the physicochemical properties and saccharification characteristics for white ginseng, red ginseng and extruded white ginseng at various conditions. The extrusion conditions were barrel temperature of 100, 120, and 140℃ and moisture content of 20 and 30%. Crude ash and protein content of ginseng extrudates were not changed by extrusion. Crude fat content decreased after extrusion process. Reducing sugar content of red ginseng was highest(126.83 mg/g) and extruded white ginseng(140℃, 20%) was lowest(41.49 mg/g). Total sugar content of white ginsengs increased through extrusion process. Crude saponin content of red ginseng was highest with 51.93 mg/g. Crude saponin content of white ginseng increased through extrusion. The effect of moisture content was more significant than barrel temperature in increasing crude saponin content. Browness and redness of extruded white ginsengs increased at high barrel temperature and low moisture content. Water soluble index and water absorption index increased with increase in barrel temperature and decrease in moisture content. Saccharification rate constant of extruded white ginseng at 100℃ barrel temperature and 20% moisture content was the highest(9.5592 mg/mL·hr1/2).
