METHODS OF TEST FOR PALM OIL AND PALM OIL PRODUCTS : PART 7: DETERMINATION OF UNSAPONIFIABLE MATTER : SECTION 1: METHOD USING DIETHYL ETHER EXTRACTION (REFERENCE METHOD)(ISO 3596:2000, IDT)
This Malaysian Standard specifies the reference method using diethyl ether extraction for the determination of the unsaponifiable matter of palm oil and palm oil products.
This method is not applicable to waxes.
NOTE. MS 817 : Part 7 : Section 2 describes a method using nine hexane extractions which gives similar results formany animal and vegetable fats and oils, but because of differences of solubility of some constituents of the unsaponifiable matter in the two solvents, the results may not be identical, the hexane method giving lower results.The hexane method may be used when climatic conditions, or regulations, do not permit the use of diethyl ether.
