Niveles de calcio, magnesio, manganeso, zinc, selenio y cromo en aceites de oliva comercializados en Andalucía

摘要: We determined the presence of Ca, Mg, Mn, Zn, Se and Cr in 64 samples olive virgin oil, oil marc produced Andalusia, southern Spain. Flame atomization atomic absorption spectroscopy was used for Ca electrothermal mode Cr. Samples were previously ashed with HNO 3 V 2 O 5 . Analytical conditions optimized to control interference obtain appropriate accuracy precision factors. The method is potentially useful quality oils. concentrations ranged from 0.055 2.725 mg/kg Ca; 0.300 5.300 13.213 296.356 m g/kg 8.758 36.575 undetectable 178.515 Se, 41.510 No statistically significant differences found between three types these elements. There correlations pairs Se-Cr, Mn-Cr, Mg-Zn, Ca-Zn Ca-Cr. Because high intake our setting, this food can be considered a major source essential elemental nutrients.
