High sensitivity determination of mineral oils and olefin oligomers in cocoa powder and related packaging: Method validation and market survey.

Mineral oil saturated (MOSH) and aromatic hydrocarbons (MOAH) and related hydrocarbons of synthetic origin are both packaging and processing contaminants of health concerns. The purpose of this work was to validate a method for their rapid and high-sensitivity determination in cocoa powder, using it to monitor the presence of these contaminants in products purchased in Italy and North Macedonia. Relevant primary and secondary packaging was also analyzed.
