| Portuguese abstract | Objective: Lately, scientific knowledge on fats and oils has changed dramatically, not only in relation to medical-pharmacological and nutritional fields, but also to the knowledge of chemical compounds deriving from oxidative reactions and contaminants (such as polycyclic aromatic hydrocarbons) due to undesired effects on human body, associated with several degenerative diseases on the organism such as arteriosclerosis, cardiovascular changes and carcinogenesis. This paper has focused its attention on the presence and quantification of these compounds in olive oils imported and marketed domestically in Brazil. Methods: For analysis of natural antioxidants, determination of hydrolysis and oxidized compounds, and screening and authenticity of polycyclic aromatic hydrocarbons, UV high pressure liquid chromatography (HPLC) was used following the methods reported in the bibliography. Results: The samples showed significant contents of oxidized composts and low nutritional health quality indexes. The content of polycyclic aromatic hydrocarbons was within the European Community legislation limit. One of the parameters utilized for authenticity determination, based on equivalent carbon number (ECN42) difference analysis, showed values within the legislation limits for all samples analyzed. Conclusions: The samples show significant contents of oxidized compounds and low nutritional health quality indexes, independent of expiry date. The authenticity determination, based on ECN42 difference analysis, show values within the limits for all samples analyzed. The content of polycyclic aromatic hydrocarbon contaminants was within the European Community legislation limit |
