Abstract
The quality of edible oils regarding their freshness, storability and toxicity can be evaluated by
the determination of different macro and trace elements. The quantification of trace elements in oil
samples is particularly difficult to perform, as some of them are present at very low concentration
levels; therefore, sample preparation is a critical step in the whole analytical procedure. This work
presents a quantification approach for elements determination in different types of cold pressed and
refined edible oils using inductively coupled plasma -mass spectrometry (ICP-MS) with previously
microwave digestion of the oil samples. Studying the content of trace elements, in order to detect
tendencies in the samples of the same type of oil, principal components analysis was used. Promising
groupings were observed using a model with two principal components.
