摘要
初步研究了无机膜提取栀子黄色素的工艺过程，采用无机陶瓷微滤膜对浸提液进行精密过滤，再用反渗透膜浓缩过滤液，确定了无机陶瓷膜微滤的操作条件。研究表明。
A new method for the preparation of gardenia yellow pigment by membrane processes is proposed. Main attentions are paid to select the proper operating conditions for ceramic microfiltration membrane process and the reverse osmosis process. The results show that membrane separation technology is a promising new technology for the preparation of natural pigment.
