Determination Unsaponifiable Matter in Oils and Fats

Hydrocarbons, sterols and aliphatic alcohols with high molecular masses form unsaponifiable substances in oils and fats. By determining the unsaponifiable substances in fats and oils, the identification of oils and the detection of natural or intentional impurities can be achieved. For example, it is important to evaluate unsaponifiable substances in detecting counterfeiting in mineral oils.

In general, all existing methods for the determination of unsaponifiable matter involve saponification of the sample with ethanolic potassium hydroxide, dilution with water and diethyl ether, light petroleum. or extraction with solvents such as hexane.
