Abstract:
The antioxidant capacity of molasses was evaluated with organic free radical DPPH scavenging reaction system. The wavelength for the determination of DPPH reaction system by spectrophotometric method was chosen as 517.0 nm and the value of molasses concentration for scavenging half of DPPH （1.2×10-4 mol/L）radica1 (IC50 value) was used as the index to evaluate scavenging capacity. Results showed that IC50 values for molasses with and without electrodialysis treatment were 0.2887 mg/mL and 0.3669 mg/mL, respectively. It was concluded that that the electrodialysis treatment could reduce the antioxidant capacity of molasses.
