On-line and automated LC-SE-LC-GC-FID was used for the analysis of pol
yaromatic hydrocarbons in foods contaminated with mineral oil products
. The detection limit for a fraction was around 1 mg/kg. Batching oil
from jute bags introduces two-ring and three-ring aromatic compounds i
nto foods (shown for rice), and environmental contamination of fish in
troduces primarily two-ring compounds. For other foods containing mine
ral oil material from unknown sources, the analysis provided important
information about the type of oil involved (shown for a sample of lin
seed oil, a safflower oil and a chocolate).
