| Abstract: | 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. |
