An oil and fat composition is provided which can reduce cooked odors without using an additive such as emulsifier. The oil and fat composition includes an oil and fat produced by oxidizing a fresh oil and fat so that a difference in anisidine value before and after the oxidation is 0.5 to 350, and an edible oil and fat. An added anisidine value of the oil and fat composition is 0.07 to 350 and is further calculated by the following formula: added anisidine value=(anisidine value after oxidation−anisidine value before oxidation)×[additive amount (wt. %)].
