Description Ghee is a high-priced product that costs three to six times than the edible vegetable oil. Ghee is frequently adulterated with low-cost vegetable oil (palm oil). Dry fractionation is one of the cost-effective methods of modifying the physical properties of milk fat. Natural antioxidant present in palm oil is believed to enhance the oxidative stability of ghee. Therefore, in the current study, ghee was intentionally blended with palm oil at levels of 0, 5, 10, and 20%. Then the ghee was fractionated to separate liquid and solid portions by dry fractionation technique. The antioxidant activity accessed by the 2, 2-diphenyl-1-picrylhydrazyl (DPPH) method shows that as the palm oil level increased the antioxidant activity in the prepared samples. This could be due to carotenoids and vitamins E which act synergistically as powerful natural antioxidants which also contribute better towards stability against auto oxidation (peroxide value).The liquid fraction (L20 with palm oil 20%) has a high level of antioxidant activity. Fractionated ghee showed higher antioxidant activity as compared to ghee due to liquid fraction which had the higher antioxidant activity as to it is very rich in vitamin E, especially tocotrienols and tocopherols. The peroxide value and free fatty acid content of ghee were determined during storage at 30°C and 60°C for 90 days.
