Conteúdo: | The application of the FOX2 (ferrous oxidation in xylenol orange, version 2) method to the measurement of hydroperoxides in edible oils is described. Sample preparation involves dissolving oil (10 mg) in 1 mL of propan-1-ol and mixing an aliquot (100 L) with 900 L of the FOX2 reagent in a 1.5 mL microcentrifuge tube. Absorbance of the supernatant is read at 560 nm following incubation for 30 min at room temperature and centrifugation at 12000g for min. Analysis by the FOX2 assay of 21 varieties of freshly opened vegetable oils revealed that edible oils contained 0.96-6.74 mmol kg of hydroperoxides. The intra-assay coefficient of variation for the FOX2 assay was generally less than 10%.
