摘要：

Pigment was extracted to decolor the sugarcane juice alcohol wastewater and its antioxidant activities were evaluated. The pigment was extracted using ion exchange fiber along with macroporous resin D-101 as the absorbent and an ethanol-water mixture (6:4, v/v) as the eluent. Total flavonoid and phenolic contents of the pigment were determined. DPPH radical scavenging ability and reducing power of 1.0 mg/mL of the pigment were approximately 78.5 and 16.8%, respectively, compared to 1.0 mg/mL of the tea polyphenol (positive control). The hydroxyl radical scavenging ability of 10.0 mg/mL of the pigment was about 92.5% compared to that of positive control. The DPPH radical scavenging ability of the pigment was enhanced significantly with thermal treatment at 70 and 100A degrees C. The result shows the proposed procedure can be effective to decolor such wastewater and to get antioxidative pigment.
