CEN - EN ISO 9936

Animal and vegetable fats and oils - Determination of tocopherol and tocotrienol contents by high-performance liquid chromatography

inactive
Organization: CEN
Publication Date: 1 April 2006
Status: inactive
Page Count: 26
ICS Code (Animal and vegetable fats and oils): 67.200.10
scope:

This International Standard specifies a method for the determination of the contents of free α-, β-, γ-, and δ-tocopherols and tocotrienols (referred to jointly as tocols) in animal and vegetable fats and oils (referred to hereinafter as fats) by high-performance liquid chromatography (HPLC).

For products containing tocopherol or tocotrienol esters, it is necessary to carry out a preliminary saponification.

NOTE A suitable method involving a cold saponification procedure is described in Annex B for information only.
