1 Scope
This International Standard specifies a method for the determination of saturated
aliphatic hydrocarbons from C10 to C56 of natural origin present in vegetable oils,
and for detecting the presence of mineral oil and diesel oil.
The method is applicable to all types of crude and refined edible oils and fats, for
concentrations of mineral oils from 50 mg/kg to 1 000 mg/kg.
A rapid method for refined and virgin (or cold-pressed) oils is proposed in Annex C. This rapid method is not adapted for crude oils due to a lack of retention of triglycerides
observed for some samples.
A method for fat recovery from food samples by soxhlet extraction with a blend of
solvents is proposed in Annex D.
