This International Standard specifies a thin-layer chromatographic method for the detection and identification of the following antioxidants in animal and vegetable fats and oils:
- nordihydroguairetic acid (NDGA)
- propylgallate (PG)
- octylgallate (OG)
- dodecylgallate (DG)
- tertiobutylhydroquinone (TBHQ)
- butylhydroxyanisole (tert-butyl-4-methoxyphenol) (BHA)
- α-tocopherol
- butylhydroxytoluene (2,6-di-tert-butyl-4-methylphenol) (BHT)
The antioxidants are listed in the order of their Rf values.
The detection of α-tocopherol is sometimes difficult as the spots of this antioxidant are of a generally diffuse aspect.
The method has limits of detection of 20 mg/kg (ppm) for BHT, and 10 mg/kg (ppm) for the other antioxidants. It should be noted that BHT is not completely isolated by this method.
