Data refer to three average batches from each brand of infant formulas marketed in Brazil. Each sample was analyzed in quintuplicate, and data are reported as means ± SD. Different superscript letters in the same column indicate significant differences among the IFs at a significance level of p <0.01. IFs, infant formulas.
