영문 초록

The contents of starch, moisture, crude pro-tein, crude fat, crude fiber, and ash of different varieties of various crops such as brown rice, barley, corn, sweet potato were analyzed. The average starch contents of brown rice, barley, corn, and sweet potato were 70.1±0.4 ~ 72.2± 2.1, 68.7±0.2 ~ 71.4±1.2, 67.6±0.8 ~ 69.4±1.8, and 21.7± 0.9 ~ 28.3±0.5%, respectively. The ground powder of each starchy substrate was suspended in distilled water, and then liquefied, saccharified, and fermented by dried active yeast at 32 for 4 days. By statistical analysis, the effectiveness ℃ of the contents of the different components such as starch, moisture, crude protein, crude fat, crude fiber, and ash of the crops on the ethanol production were examined. The results showed that the starch content positively affected the ethanol production in all the tested cereals and sweet potato. In brown rice, ash content affected negatively the ethanol production. In barley, protein content affected nega-tively the ethanol production, while fiber content affected positively the ethanol production. The sweet potato con-taining higher content of moisture produced less amount of ethanol.
