### Evaluation of Compliance with the Content of Determined Mineral Components in Infant Formulas
#### 3.4.1 Conventional Initial and Follow-On Infant Formulas  
Compared to the European Commission's mineral content range, of the initial IFs, only C-BI exceeded the recommended Fe content by about 5%, whereas in C-C1, the labeled Na value was 14% lower than the range of values set by European standards. The contents of the other minerals were within the specified ranges in the other IFs. The largest deviation in the mineral content assessment determined and declared by the IF manufacturers was recorded for Fe. In C-C1 and C-D1, the marked Fe values were 23 and 13% lower than the labeled values. On the other hand, in C-A1 and C-B1, about 40 and 70% more Fe was identified than the manufacturer declared on the label. For Ca, there have been deviations from labeled values in the range of 5-20%. For other minerals, C-A1 showed almost 30% lower and almost 40% higher Mg and Mn contents relative to label specifications. In addition, in C-B1, the marked \(p\) value was more than 50% higher than that declared by the manufacturer. In follow-on IFs, all the marked mineral values were within the range specified by the European Commission [15; 25]. As in the initial IFs, the greatest deviations from the mineral values marked and declared by the manufacturer were recorded in the Fe content. In C-B2 and C-C2, the marked Fe values were about 50%, and in C-D2, more than 20% lower than those declared by the manufacturer. The smallest deviations were recorded for Zn (up to 9%) and Cu (up to 15%). The determined Mg contents were 15-23% lower than those declared by the manufacturers. \begin{table}
