For olive oils, the EU Reg. 432/2012 introduced the possibility to report the health claim “Olive oil polyphenols contribute to the protection of blood lipids from oxidative stress” in the label, if the product contains at least 5 mg of hydroxytyrosol and its derivatives (e.g. oleuropein complex and tyrosol) per 20 g of product. As reported in previous investigations, such a claim is rather confusing because of the method for the quantification of secoiridoid aglycons (Brenes at al., 2012). The aim of this work was to find a method for improving the estimation of the hydroxytyrosol and its derivatives content in olive oil, also taking in consideration previous experiences (Mulinacci et a., 2006), as requested by the EU regulation.

Abstract

For olive oils, the EU Reg. 432/2012 introduced the possibility to report the health claim “Olive oil polyphenols contribute to the protection of blood lipids from oxidative stress” in the label, if the product contains at least 5 mg of hydroxytyrosol and its derivatives (e.g. oleuropein complex and tyrosol) per 20 g of product. As reported in previous investigations, such a claim is rather confusing because of the method for the quantification of secoiridoid aglycons (Brenes at al., 2012). The aim of this work was to find a method for improving the estimation of the hydroxytyrosol and its derivatives content in olive oil, also taking in consideration previous experiences (Mulinacci et a., 2006), as requested by the EU regulation.
