4. Conclusions
A MAS procedure allowing for rapid extraction of mineral oil
contamination present in cereal-based products of different water
and fat content, has been optimised and validated. The proposed
method allows simultaneous saponification and extraction of up
to 14 samples, with minimal sample manipulation and solvent
consumption. Since MAS eliminates fat, it is particularly advantageous
for high-fat-content samples, for which sensitivity is limited
by the maximum amount of fat than can be injected into the LC
