1 Scope

This standard specifies the method for the determination of mineral oil content in food simulants by gas chromatography. This standard applies to mineral spirits in food simulants (water, 3% acetic acid, 10% ethanol and isooctane) in contact with food contact paper and paperboard. Determination of the content.

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Mineral oil saturated hydrocarbon mineral oilsaturatedhydrocarbons; MOSH Saturated open chain alkanes and cycloalkanes, including linear, branched saturated alkanes and alkyl substituted cyclic saturated alkanes. 3.2 Mineral oil aromatic hydrocarbon mineraloilaromatichydrocarbons; MOAH Highly alkylated monocyclic aromatic hydrocarbon or polycyclic aromatic hydrocarbon.

4 Principle

The food simulant obtained by the migration test is extracted and enriched by n-hexane, and the MOSH portion of the mineral oil is separated and eluted by a solid phase extraction column. The MOAH part was concentrated and constant volume, and determined by gas chromatography flame ionization detector (FID) and quantitatively calculated by internal standard.
