摘　　要：在室温下,葡萄糖溶液的水分活度与果汁的水分活度相当,本研究以葡萄糖溶液为果汁模拟液进行了OD浓缩的试验研究,分析了盐溶液的浓度、进料液的浓度、流速等条件对OD膜通量的影响,并在此基础上进行了OD浓缩澄清橙汁的可行性研究,证明OD可在室温下将8.8°Brix的澄清橙汁浓缩至63°Brix。Tbe water activity of glucose is very similar to that of many fruit juices at room temperature. Glucose solution used as model juice was concentrated by osmotic distillation. The effect of brine concentration, feed concentration and feed cross flow velocity on vapor flux is studied. On this basis, the concentration of clarified orange juice by osmotic distillation was carried out. It could be concluded that the clarified orange juice can be concentrated from 8.8°Brix to 63°Brix by osmotic distillation.
