Sažetak
Macromineral and microelement contents were measured by inductively coupled plasma-optical emission spectrometry in 51 dairy products (milk, four types of cheese and butter). Significant differences in the concentrations of Ca, K, Na, Mg, Zn and Cu were observed (p < 0.05, all) between dairy products. Higher levels of Ca, Na, Mg and Se were measured in hard cheese than in semi-hard, fresh and cream cheese samples. The highest mean levels of elements were measured in products (mg kg −1): milk: K 2070 ; hard fat cheese: Ca 10700, Na 10300, Mg 440, Zn 91.3, Se 0.78 ; cream cheese: Cu 3.12, Fe 3.9 ; butter: Se 0.79. The estimated daily intakes (EDIs) calculated for milk show contribution to the recommended dietary allowance (RDA) for the elements (%): Ca 42, K 13.2, Mg 10.3– 13.3, Zn 11.4-15.7, Se 13.1. The highest contribution of elements to the RDA values was determined for hard fat cheese (%): Na 7.93, Zn 16.6-22.8, Se 28.4. However, a contribution to the RDA of less than 1% was determined for K, Mg and Fe in cheeses. The contribution of Cu to the RDA value ranged in cheese samples between 2.78–6.93%, though this was less than 1% in milk.
