Abstract The best technological parameters and antioxidant properties of black rice pigment were studied. The results showed that in the process of extracting black rice pigment， when the solid-liquid ratio reached 1∶6 and the extraction duration was about 30 min， the extraction effect could reach the best. Black rice pigment can scavenge DPPH radical， superoxide anion and hydroxyl radical， which provides a theoretical basis for the wide application and research of black rice pigment in food， biomedicine and other fields.
