Samples of different brands of banaspati ghee (Hydrogenated vegetable oil) were procured from local market in Peshawar. Nickel, Pro-oxidants and other heavy metals in these samples were determined by microwave acid digestion method and were analyzed by atomic absorption spectrometry, to evaluate the value of different brands of banaspati ghee found in the local Peshawar market. Microwave acid digestion program was developed to give reliable estimates for metals in small sample (0.5g) of banaspati ghee. It reduced the external contamination and required small quantities of acid, improving the detection-limits and overall accuracy of the analytical method. Iron and copper concentrations were found in ranges of (0.44 to 4.64 ppm), (0.072 to 0.38 ppm), respectively. Nickel ranged (0.098 to 0.24 ppm), while the concentrations of chromium, cadmium, lead, manganese and zinc ranged (0.035 to 0.15ppm), (0.022 to.16ppm), (0.025 to .095ppm), (0.029 to 12 ppm) and (0.019 to 13 ppm), respectively.
