The methods used to measure Se (HG–AAS) and Cu, Cr, and Mn
(ETA–AAS) are appropriate for microelement determination in
fermented goat and cow milks. The fermenting microorganisms
employed in the yoghurt manufacture did not influence Se, Cr,
Cu, or Mn levels. Thus, specifically the probiotic strain used to produce
our-lab goat yogurt had no influence on mineral levels. Se
was the only microelement studied that showed lower levels in
goat versus cow milk yoghurts. Given the recommended Se, and
overall Cr intakes for healthy adults, fermented goat and cow milk
products may be important dietary sources for these elements.
