|
In order to enhance the yield and physical property of Korean red ginseng extract, preheating stage was added to the inception of red ginseng manufacturing process and its effect was investigated. Preheating of raw ginseng at $70^{\circ}C$ 수식 이미지 for 2 hour followed by steaming for 2 hours increased the yield of water and 60% alcohol extract most effectively. Those yields were the highest at the same condition as above except preheating time shortened to 1 hour at $70^{\circ}C$ 수식 이미지. Steaming time had little effect on the yield of water and 60% alcohol extract. The content of starch in red ginseng was reduced effectively by preheating of raw ginseng at $70^{\circ}C$ 수식 이미지. The brown color intensity of red ginseng increased in proportion to preheating temperature in the range of $50-70^{\circ}C$ 수식 이미지. However, there was no increase in the color intensity at $80^{\circ}C$ 수식 이미지.
