优化大孔树脂提取分离苋菜红色素的工艺

Optimization of Extraction and Separation of Red Pigment from Amaranthus Paniculatus with Macroporous Adsorption Resin

摘要:

采用正交设计实验筛选AB-8大孔树脂纯化苋菜红色素的最佳工艺条件。其最佳工艺为：上样pH值为3、吸附流速1.2 mL/min、洗脱剂浓度为15%乙醇溶液、洗脱流速0.9 mL/min。经过AB-8大孔树脂提纯后，提高了苋菜红色素的品质。

Abstract:

AB-8 resin was selected out to purify the red pigment of Amaranthus paniculatus by orthogonal design. The best conditions for isolation of the red pigment of Amaranthus paniculatus were determined as follows: pH 3, adsorption velocity 1.2 mL/min, solution adsorbent 15% ethanol and elution velocity 0.9 mL/min. After AB-8 macroporous resin purification, greatly enhance the pigment quality.
