摘　　要：本研究采用膜分离装置对南瓜汁进行了超滤澄清处理,分析了超滤过程中膜孔径、操作压力和操作温度对膜通量的影响。结果表明,南瓜汁经过微滤后,选用截留相对分子质量5万的聚砜卷式超滤膜,在操作压力0.3 MPa,最适温度35℃时进行全回流超滤试验,膜通量至少可达到30.23 L.m-2.h-1,且得到澄清透明的南瓜汁饮料。In the paper, pumpkin juice was ultrafiltrated by experimental membrane separation module, the effects of operating parameters including membrane pore diameter, pressure, temperature on the membrane flux were also studied, The results showed that after treating with microfilter, the more stable clear pumpkin juice was obtained and the membrane flux was 30,23 L·m^-2·h^-1, at least by using polysulphone tape ultrafiltration membrances of 50 000 at 0.3 MPa, 35 ℃.
