Pomegranate peel powder and grape seed powder are good natural antioxidants. Experiments were conducted by adding these powder in ghee as antioxidants to replace BHA which is a potent carcinogen. Sample with different concentrations of pomegranate peel powder and grape seed powder viz., 0.5 per cent, 1 per cent, 1.5 per cent and 2 per cent. Control and 0.02 per cent BHA sample were also prepared. Sensory evaluation was done to optimise the best concentration of and optimised concentration to 1.5 per cent. Chemical analysis was done for 21 days at an interval of 3 days. It was observed that there was a steady increase in PV value in all treatments however it was less in case of pomegranate peel powder (0.968) which indicated that its high potentiality as antioxidant. Thiobarbituric Acid value was found to be 0.047 in grape seed powder treatment on 21st day which was the lowest among the group and remarkable. It was observed that grape seed powder sample’s value had comparatively less Carbonyl values (0.516) indicating low oxidative rancidity. From the above experiment, it was concluded that grape seed powder could be used as an antioxidant additive for ghee and suitable replacement for BHA.
