The method used is descriptive method with the treatment of variations in temperature and roasting time. The results of the analysis for antioxidant activity ranged from 36.01 - 47.66% inhibition obtained with IC50 values between 41.44 - 93.37 μg / ml. antioxidant properties with a very strong category in treatment B (temperature 180 ℃ with a roasting time of 30 minutes) and in treatment C (temperature 220 ℃ with a roasting time of 22 minutes).
