METHODS OF TEST FOR PALM OIL AND PALM OIL PRODUCTS : PART 6: DETERMINATION OF TOCOPHEROLS AND TOCOTRIENOLS CONTENT – METHOD USING HIGH-PERFORMANCE LIQUID CHROMATOGRAPHY (SECOND REVISION) (ISO 9936:1997, IDT)
This Malaysian Standard specifies a method for the determination of the contents of free a-, b-, g- and d-tocopherols and tocotrienols (referred to jointly as tocols) in palm oil and palm oil products (referred to hereinafter as fats) by high-performance liquid chromatography (HPLC).
For products containing tocopherol or tocotrienol esters, it is necessary to prepare theunsaponifiable matter.
NOTE. A suitable method involving a cold saponification procedure is described in Appendix A for information only.
