摘　　要：本文利用单因素实验和正交试验,深入研究并确定提高葡萄糖异构反应转化生成甘露糖收率的反应条件。通过正交试验并结合实际情况,得出的实际优化条件为:钼酸铵用量为葡萄糖量的0.4%、反应温度98℃、反应时间150min、反应液pH值0.2、糖液浓度55%,所得到的甘露糖收率可达到32.6%。The optimum reaction conditions which could increase the yield of mannose from glucose by epimerization conversion were studied and obtained. Combined with the orthogonal test and the actual situation, the actual optimal conditions were： ammonium molybdate consumption 0.4% of glucose, reaction temperature 98℃, reaction time 150 minutes, pH of reaction liquid 2.0, sugar concentration 55%. Under the actual optimal conditions, the yield of mannose could reach 32.6%.
