The present research is directed towards the use of a rapid heart-cutting multidimensional LCGC- FID method for the analysis of mineral oil saturated hydrocarbons (MOSH), contained in different types of homogenized solid baby food (fish, meat and fruit products). The fish and meat products all contained vegetable oil (sunflower), potentially an important source of mineraloil contamination. Sixteen commercial baby food samples were subjected to analysis, with various degrees of MOSH contamination found. Hence, MOSH contamination was found not only in the meat and fish products, but also in the fruit ones. For confirmation of the analytical findings, three of the sixteen samples were analyzed in two separate laboratories, using two distinct LC-GC methods, based on different interfaces. The results were confirmed, in qualitative terms, by collecting the LC fractions, relative to some of the food samples, and subjecting them to comprehensive two-dimensional GC-quadrupole mass spectrometry. Thus, mass spectral data were attained for the saturated hydrocarbons.

Abstract
The present research is directed towards the use of a rapid heart-cutting multidimensional LCGC- FID method for the analysis of mineral oil saturated hydrocarbons (MOSH), contained in different types of homogenized solid baby food (fish, meat and fruit products). The fish and meat products all contained vegetable oil (sunflower), potentially an important source of mineraloil contamination. Sixteen commercial baby food samples were subjected to analysis, with various degrees of MOSH contamination found. Hence, MOSH contamination was found not only in the meat and fish products, but also in the fruit ones. For confirmation of the analytical findings, three of the sixteen samples were analyzed in two separate laboratories, using two distinct LC-GC methods, based on different interfaces. The results were confirmed, in qualitative terms, by collecting the LC fractions, relative to some of the food samples, and subjecting them to comprehensive two-dimensional GC-quadrupole mass spectrometry. Thus, mass spectral data were attained for the saturated hydrocarbons.Pubblicazioni consigliate
