Toxicological Assessment of Mineral Hydrocarbons in Foods: State of Present Discussions.

The evaluation of mineral oils by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) provided high acceptable daily intakes for classes largely falling into the mass range strongly accumulated by humans. Because they are roughly 2 orders of magnitude above the present exposure, they authorize strongly increased exposure. An approach based on accumulation seems more adequate. Increased organ weights might be more critical than granulomas. Aromatic hydrocarbons with 1-2 aromatic rings should be distinguished from those with at least 3 aromatic rings. If mineral oil saturated hydrocarbon limits were low, no limit might be needed for the 1-2 ring aromatics. It should be considered to phase out substantial use of mineral oils in food application.
