Abstract
A red pigment was extracted from Amaranthas Paniculatus by ultrafiltrion-resin association technology.And ultrafiltrion-resin extracting process was studied.The result indicated that transmembrane pressure 0.10 MPa,and cross-flow velocity 1 500 L/h,the red pigment was separated effectively.The red pigment was absorbed when the filtrate courses through the HPD-100A resin,and it was desorbed by 70 % alcohol.The high quality red pigment was obtained.
