Evaluation of Cu, Mg, Fe and Na Metal Contents in Sapodilla Plum (Quararibea cordata) from Valle del Cauca, Colombia
Introduction: this article is the result of the research “Nutritional evaluation of fruits grown in Valle del Cauca, Colombia” conducted in 2014 by the University Santiago de Cali. Its purpose is to evaluate the Fe, Na, Mg and Cu minerals found in the pulp of sapodilla plum (Quararibea cordata) grown in Valle del Cauca. It uses flame atomic absorption spectrophotometry as the main method.
Methodology: the quantification was performed by determining the lineal working range; concentration was low in each metal and meted the statistical tests of system linearity, like correlation coefficient and hypothesis for pending and intercepting when using a Student t-test with a confidence of 95% (including zero).
Results: the obtained composition of minerals in the pulp of sapodilla plum was of 0,42 ± 0,03 mg Cu/100g pulp, 3,2 x 10-3 ± 0,04 mg Mg/100g pulp, 0,47 ± 0,09 mg Fe/100g pulp, and 0,03 ± 0,01 mg Na/100g pulp. The report includes low content of Mg and higher amounts of Fe and Cu.
Conclusion: the analysis method of flame air-acetylene atomic absorption spectrophotometry for evaluating iron, magnesium, copper and sodium metals found in the pulp of sapodilla plum (Quararibea cordata) grown in the Valle del Cauca region guarantees the reliability of these results.
