3.4. Mineral oil content in the analysed samples
Fig. 5 summarises the total mineral oil contamination found in a
number of cereal-based products from the Italian market, such as
dry egg and semolina pasta, and different bakery products (bread,
biscuits, cakes) with different fat, sugar and moisture content.
MOSH data were divided into three ranges of volatility: MOSH
from n-C10 to n-C16, from n-C16 to n-C25, and from n-C25 to
n-C35, while MOAH were quantified in the range n-C10–C35. MOSH
from n-C16 to n-C35 are the most relevant from a toxicological
point of view since they accumulate in human tissues, while MOSH
and MOAH up to n-C25 are often an index of the presence of mineral
oil migrated via gas phase from recycled paperboard packaging
(EFSA, 2012).
The dry semolina and egg pasta in direct contact with recycled
paperboard presented always a MOSH contamination in the range
n-C10–C25, generally centred on n-C17–C18 and accompanied by
10–25% of MOAH in the same range of volatility, as is typical for
products contaminated with mineral oils (from printing ink residues
present in recycled fibres) and migrated to food via the gas
phase. The highest contamination levels were found in an egg
