YWD-01大孔吸附树脂分离纯化黑豆红色素的研究

目的:研究大孔树脂分离纯化黑豆红色素的工艺。方法:考察六种树脂对黑豆红色素的吸附量,选出最优树脂YWD-01,考察温度、酸度对YWD-01吸附能力的影响以及不同醇浓度对该树脂的解吸作用等。结果:通过筛选YWD-01对黑豆红色素的吸附能力最强,其在pH3.0时吸附效果最好,不同的乙醇浓度对洗脱有很大影响,50%洗脱效果最好。结论:YWD-01树脂适用于分离纯化黑豆红色素,有望得到含量更高的黑豆红色素。

Study on the Absorption and Purification of Black Soya Bean Red Pigment by Macro-Porous Resin YWD-01

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.
