Titration of Acidity in Fats and Oils

Analysis outlining the titration method for determination of the acid number and free fatty acids (FFA) in fats and oils. This method is suitable for edible fats and oils such as butter, olive, palm, or sunflower oil. The acid number is the quantity of base, expressed in milligrams of potassium hydroxide, that is required to neutralize all acidic constituents present in 1 g of sample. The calculation of the % FFA depends on the titrated type of sample. The procedure is performed using the Schott Instruments TitroLine TitroLine 7000 Advanced Titrator or TitroLine 7750 Multi Parameter Titrator. Note: We recommend ready to use KOH titrants. The exact concentration of the KOH 0.1 mol/l can be determined using the titrimetric standard potassium hydrogen phthalate.
