Determination of macro and microelements in cow, goat and human milk using inductively coupled plasma optical emission spectrometry

The contents of macro and micro-elements in cow, goat and human milk from Croatia were measured and compared for the first time. The highest concentrations of element were measured in milk cow: calcium 1.4 g/kg, sodium 0.6 g/kg, zinc 4.0 mg/kg, strontium 0.4 mg/kg ; goat: magnesium 0.2 g/kg, potassium 2.2 g/kg, iron 0.8 mg/kg, manganese 71 µg/kg, selenium 35 µg/kg, molybdenum 20 µg/kg, chromium 72 µg/kg, lithium 14 µg/kg ; human: copper 193 µg/kg. Equal contents of molybdenum (20 µg/kg) were determined in cow and goat milk. Significant differences in element levels between the three species were determined. Concentrations of magnesium, manganese, selenium, chromium and lithium in goat milk were significantly higher than in cow milk. Significantly lower levels of calcium, potassium, sodium, magnesium, zinc, selenium and strontium were determined in human milk than in cow and goat milk. Chromium content was significantly higher in goat than in human milk. Copper content in human milk was significantly higher than in cow milk. Correlations, mostly moderate and positive, were found between elements in cow and goat milk.
