摘　　要：[目的]优化木薯粉与玉米粉混合发酵工艺,提高最终出酒率。[方法]研究了添加少量玉米粉以及木薯与玉米粉大比例配合对产生乙醇的影响。[结果]试验表明,添加1.0%玉米粉时效果最优,出酒提高率最大,由此说明将玉米作为助剂添加时,有利于提高木薯乙醇出酒率;当木薯与玉米粉的质量比为9∶1时,出酒率最高,同时出酒率提高最大,即木薯与玉米粉最佳配比为9∶1。[结论]研究结果对于木薯、玉米产量都较多的国家或地区发展燃料乙醇具有重要意义。[Objective] To optimize cassava flour and corn flour mixed fermentation process,improve yields of ethanol. [Method] Effects of adding small amount of corn flour,and high proportion mixing of cassava flour and corn powder on ethanol were studied. [Result] The results showed that optimal effect was observed if one percent corn flour mixed with cassava flour,which indicated the additive corn can improve the yields of ethanol; the highest production occurred when cassava and corn flour were mixed at the proportion of 9∶1（mass ratio）. Therefore,the best ratio between cassava and maize flour was 9∶1. [Conclusion]The study has significance on developing ethanol in countries and regions with high yield of cassava and corn.
