摘　　要：以栀子黄色素萃取液为原料,研究陶瓷膜微滤过程中不同膜孔径、不同操作压力对渗透通量和色素液品质的影响,确定孔径200nm的陶瓷膜、0.125MPa压力下微滤为栀子黄色素纯化的最佳工艺条件。栀子黄微滤渗透液再经聚酰胺膜纳滤,1.5MPa压力下浓缩倍数达到3倍以上。The extraction of Gardenia （Gardenia jasminoides Ellis） yellow pigment was purified and concentrated by microfiltration and nanofiltration. According to the effects of different membranes and transmembrane pressures on permeate flux and quality, ceramic membrane with pore size 200nm and transmembrane pressure of 0.125MPa was optimal for microfiltration of Gardenia yellow extraction. Then the permeate was three times its original concentration by nanofiltration under transmembrahe pressure of 1.5 MPa.
