The oil was extracted from sesame seed with two extraction
methods. Traditional (Ardeh oil) and industrial method (cold
pressing method: virgin and refined sesame oil) oil extraction
was studied to compare the quality and heavy metal content of
extracted oils. The chemical properties (fatty acid composition,
peroxide,anisidine, acid values, and TOTOX) and heavy metal
contents were investigated. The Hazard Quotient (HQ) and Hazard
Index (HI) of heavy metal intakes were calculated. The results
demonstrated that the predominant fatty acid in oil samples was
oleic, linoleic, palmitic, and stearic acids. It was indicated
the peroxide, anisidine, acid values, and TOTOX of oil samples
were as the order of Ardeh oil > virgin sesame
oil
> refined sesame oil. The reduction pattern of Pb > Zn
>Cu > Cd >As was reported in sesame seed. Although the
oil refining had greatly reduced the Pb of oil sample, it had yet
been much higher than the permissible levels set by Codex
Alimentarius. The HQ and HI of all heavy metals were less than
one, but they were higher in Ardeh oil compared to others. It is
necessary to monitor the presence of heavy metal contaminants and
the quality of imported sesame seeds prior to oil
preparation.
