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.

Describes thin-layer chromatography for nordihydroguairetic, propylgallate, octylgallate, dodecylgallate, tertiobutylhydroquinone, butylhydroxyanisole, α-tocopherol and butylhydroxytoluene.
