The TX57-Extruder (TX-57, Wenger Co., Sabetha, Kansas, USA), run by this university, was used to observe the changes in the active ingredients of ginseng. The TX57-extruder is a pilot plant twin screw extruder whose productivity is 400-800 kg/h. Ginseng and brown rice were dried (60oC, 24 h), while the sample was pulverized into 50 mesh and mixed at a ratio of 1:9 and then extruded. The extruder operating condition was activated under two conditions of barrel temperature. The extruded products with high barrel temperature showed a high expansion rate, as well as the important ingredients of ginseng. The contents of ginsenoside-Rg2 and ginsenoside-Rh2 were high. The contents of ginsenoside-Rg4 and ginsenoside-Rg5 were increased in the extruded product with high extrusion temperature compared with the white ginseng. In addition, the process to enable more efficient ginseng processing through hydration and heat treatment by steam before extrusion was executed. As a result of extrusion, the contents of ginsenosides such as Rg2 and Rg5 contained in the recently-interested black ginseng have been increased significantly in the condition of high-barrel temperature. This result shows that the process using pilot plant twin screw extruder equipment can be useful for industrialization as a method of processing ginseng.
