Abstract: Objects: Study on the absorption and purification of black soya bean red pigment by macro-porous resin. Methods: The influence factors on the absorption and desorption of YWD-01, such as temperature, acidity and concentration of alcohol were tested. Results: In the six types of macro-porous resin which were tested, the absorption ability of YWD-01 is the best. At pH3 YWD-01has greatest absorption ability. The higher the temperature the faster the absorption. When the concentration of alcohol is 50%, the desorption is most effective. Conclusion: The black soya bean red pigment of high quality can be afforded through the absorption and purification by macro-porous resin YWD-01.

Key words: black soya bean red pigment, macro-porous resin, absorption, desorption
