The content of magnesium, calcium, sodium and potassium in infant formulas
Mother’s milk is the basic food for infants. Sometimes women for various reasons cannot continue
or are not willing to continue breastfeeding their babies and then infant formula provides
an alternative. Although breast milk substitutes for infants are produced using high technology
methods, their composition is to some extent different than that of breast milk. Breast milk does
not contain a high amount of minerals on the overall (ash accounts for circa 0.2 %) but they are
characterised by a very high level of assimilability. On the other hand, cow’s milk contains
much higher amounts of minerals – ca. 0.7%. Cow’s milk contains 3 to 4 times more Ca, Mg, Na
and K than breast milk. The study aimed to analyse infant and baby formulas in terms of the
content of Ca, Mg, Na and K. The study covered 11 infant formulas. All the formulas were annotated
as “food for particular nutritional uses”. The powdered milk formulas were purchased
from retailers in Lublin Voivodeship in August 2014, prior to their best-before dates. The content
of Ca, Mg, Na and K was determined by means of flame atomic absorption spectrometry in
a Varian SpectrAA 280 FS apparatus. It was found that starter infant formulas contained less
of minerals covered by the study than had been declared. It was demonstrated that the content
of Ca, Mg, Na and K in the analysed milk samples calculated per 100 kcal was generally comparable
to their standard content
