Study on Separation and Purification of Roselle Red
In this paper,the effects of macroporous adsorption resin,aqueous two-phase extraction and membrane separation technology on the separation and purification of roselle red were studied by using roselle red extract as raw material,and the resin type and membrane pore size were discussed.The results showed that the color value of roselle red extract increased from 9.2 to 89.2 after macroporous adsorption resin,aqueous two-phase extraction and membrane separation and purification,and the separation and purification effect was remarkable.
