Values are means ± standard deviation of three replicates (n = 3). In the same line, values followed by different superscript letters are significantly different (p < 0.01). Wp = whole pulp of fresh fruit; Pt = pulp of fruit dried from the tree; Pm = Pulp of fruit purchased from the market. Cu: Copper; Zn: Zinc; Mn: Magnesium; Fe: Iron; Ca: Calcium; Mg: Manganese; K: Potassium; Na: Sodium.
