Abstract
This study evaluated the effects of lutein or β-carotene incorporation (0.1 mg/ml) on the quality, sensory attributes and stability of Arbequina, Picual or Royal monovarietal extra virgin olive oils. The fortification significantly decreased (p value < 0.05) the chemical quality of the fortified oils (peroxide values: +3% to +34%; extinction coefficients: +4% to +55%). The negative impact was higher on Arbequina oil, followed by Royal and Picual oils, especially in lutein fortified oils. Nevertheless, all fortified oils fulfilled the legal thresholds required by extra virgin category. Compared ...
