Analytical Techniques for Mineral Oil Migration in Food Packaging
Summary
The monitoring of mineral oil migration into food matrices has evolved through the integration of advanced separation and detection platforms. Initial approaches relied on one-dimensional liquid chromatography coupled with gas chromatography and flame ionisation detection (LC-GC-FID) to quantify saturated (MOSH) and aromatic (MOAH) fractions. Recent methodological refinements include comprehensive two-dimensional gas chromatography (GC×GC) interfaced with time-of-flight mass spectrometry (ToF-MS) or flame ionisation detection, offering superior resolution of complex hydrocarbon profiles and enhanced sensitivity for low-level migration. Suspect-screening workflows employing high-resolution mass spectrometry (HRMS) now permit the untargeted identification of non-intentionally added substances (NIAS), while tailored simulants and accelerated migration protocols improve the relevance of migration data to real-world food contact scenarios. Emerging nuclear magnetic resonance (NMR) methods provide a solvent-free alternative for rapid quantification of MOSH and MOAH in simplified matrices. Across all techniques, standardised sample preparation—including solid-liquid extraction, size-exclusion chromatography and selective clean-up—remains critical to minimise matrix interferences. Harmonised validation through interlaboratory comparisons has steadily improved repeatability and accuracy, supporting regulatory compliance and risk assessment at global scale.

Analytical Techniques for Mineral Oil Migration in Food Packaging publication trend
The graph below shows the total number of articles in analytical techniques for mineral oil migration in food packaging across all publications each year (not limited to Nature Index journals).
Technical terms
Mineral Oil Saturated Hydrocarbons (MOSH): Aliphatic and cycloaliphatic hydrocarbons derived from petroleum that migrate preferentially into fatty food matrices and are quantified as a chromatographic fraction.
Mineral Oil Aromatic Hydrocarbons (MOAH): Aromatic and polycyclic aromatic hydrocarbons in mineral oil known for potential genotoxicity; require high-resolution separation to resolve toxicologically relevant subfractions.
Liquid Chromatography–Gas Chromatography–Flame Ionisation Detection (LC-GC-FID): A hyphenated technique combining liquid-phase clean-up and pre-separation with gas chromatographic analysis for quantification of MOSH and MOAH.
Comprehensive Two-Dimensional Gas Chromatography (GC×GC): An advanced separation method employing two distinct stationary phases in series to resolve complex hydrocarbon mixtures with peak capacity far exceeding one-dimensional GC.
Non-Intentionally Added Substances (NIAS): Migrant species not deliberately added during manufacturing, including reaction by-products, oligomers and contaminants detectable through suspect and non-targeted screening workflows.
