| Description |
A new method is presented for the qualitative and quantitative estimation of trace amounts (up to 0.15 ppm) of
benzene in crude as well as refined vegetable oils obtained by extraction with food grade hexane (FGH), and in
the oil seed cakes left after extraction. The method involves the selection of two solvents; cyclohexanol, for
thinning of viscous vegetable oil, and heptane, for azeotroping out trace benzene as a concentrate from the
resulting mixture. Benzene is then estimated in the resulting azeotrope either by UV spectroscopy or by GC-MS
subject to availability and cost effectiveness of the latter. Repeatability and reproducibility of the method is within
1–3% error. This method is suitable for estimating benzene in vegetable oils and oil seed cakes.
