Both the addition of anthocyanin extracted from purple car- rots extract and BHT as antioxidant for sunflower oil retarded the changes in peroxide value of sunflower oil during 7 days of storage at 60 °C. It is evident from these results that, as the concentration of antioxidant increased, inhibitory effect on peroxides value increased considerably as shown in Table 8. After 7 days of storage at 60 °C, peroxide values on sunflower oil treated with 200, 500 and 1000 ppm of purple carrots anthocyanin were 12.30, 9.60 and 7.90 meq/kg
