Minerals occur in all foodstuffs as well as in milk and dairy products. The mineral content in milk is influenced by many factors ranging from environmental conditions during pasture, feeding, breeding, stage of lactation and climate to post-milking handling, transportation and processing. The aim of the study was to assess whether the intakes comply with Recommended Dietary Allowances (RDA), Adequate Intakes (AIs) or Tolerable Upper Intake Levels (ULs) for essential elements. Milk samples from different producers and with different fat content were purchased from Zagreb’s market four times in year 2007 and analysed. Concentrations of ten minerals (Ca, P, Mg, Fe, Cu, Zn, Mn, Ni, K and Na) were determined by atomic absorption spectrometry. Mean values of mineral contents were in range with the literature data. The daily intakes of these minerals by school children selected in age-gender groups (school children 8-9 years old and adolescents 15-18 years old) through milk consumption were also estimated. The average daily intake of essential minerals ranged from a minimum of 1.36 % of manganese up to 35.27 for phosphorus, irrespective of age and gender of children.

Na udjel minerala u mlijeku utječu mnogi faktori, od uvjeta zaštite okoliša za vrijeme ispaše, hranjenja, uzgoja, stadija laktacije i klime do postupaka nakon mužnje, transporta i obrade. Cilj istraživanja bio je procijeniti je li unos esencijalnih minerala u skladu s vrijednostima za Preporučene dnevne unose (RDA), Adekvatne unose (AIs) ili Maksimalno dozvoljene dnevne unose (Uls) za esencijalne elemente. Analizirani su uzorci mlijeka različitih proizvođača, s različitim udjelom masti, a nabavljeni su na zagrebačkom tržištu četiri puta tijekom 2007. godine. Udjeli deset minerala (Ca, P, Mg, Fe, Cu, Zn, Mn, Ni, K and Na) određeni su pomoću atomske apsorpcijske spektrometrije. Srednje vrijednosti udjela minerala bile su u skladu s literaturnim podacima. Također je procijenjen dnevni unos navedenih minerala putem mlijeka, kod djece školskog uzrasta (školska djeca u dobi 8-9 godina i adolescenti u dobi 15-18 godina) podijeljene u grupe obzirom na godine i spol. Prosječni dnevni unosi esencijalnih minerala kretali su se od minimalno 1,36 % za mangan do maksimalno 35,27 % za fosfor, bez obzira na dob i spol djece.

Minerals occur in all foodstuffs thus a milk and dairy products. The mineral content in milk is influenced by many factors ranging from environmental conditions during pasture-fed, feeding, breeding, stage of lactation and climate to post-milking handling, transportation and processing. In this work milk samples are purchased from market four times in year and analyzed. Concentrations of 11 minerals were determined by atomic absorption spectrophotometry. The daily intakes of these minerals by school children selected in age-sex groups through milk consumption also been estimated. The aim of the study was to assess whether the intakes comply with recommended dietary allowances (RDA)for essential and permissible levels for toxic elements. The calculated average daily intakes of essential minerals were not close to the recommended intakes for determined age-sex children groups. Calculated daily intakes of toxic heavy metals through milk consumption were well below the permissible levels.
