Antioxidant activities of butylatedhydroxyanisole
(BHA) and orange peel powder extract in ghee stored at different
storage temperatures (T1:6±2 °C; T2: 32±2 °C; T3:60
±2 °C) were evaluated during storage period of 21 days.
Peroxide value (PV), thiobarbituric acid (TBA), radical scavenging
activity (RSA) and free fatty acids (FFA) of ghee samples
were analyzed during the study. PV, TBA and FFA of
ghee samples increased significantly while radical scavenging
activity (RSA) of ghee samples decreased significantly at accelerated
temperature (T3) as compared to the temperatures at
T1 and T2. Effect of storage temperature on development of
peroxides and TBA of ghee samples was significantly higher
than the effect of treatment and storage period while treatment
had more significant effect on the change in FFA and RSA as
compared to storage temperature and storage period. Ghee
incorporated with orange peel extract (OPE) showed stronger
activity in quenching DPPH radicals and least development of
PV, TBA and FFA than ghee incorporated with BHA and
control. The study revealed that orange peel could be a good
