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.
