The aim of this master´s thesis was to determinate selected nutrients in hen eggs depending on the time of their storage. The content of nutrients in hen albumen, hen yolk and hen melange was measured in fresh eggs ang in storaged eggs after one, two, eight, fiveteen, twenty nine, forty three and fifty seven days. Teoretical part of thesis is focused on chemical composition of hen egg, breeding, history, storage and consumption. Another part of thesis deals with selected nutrients, specifically by magnesium, copper, calcium, zinc and iron. In practical part the results are presented. The content of these elements was determined with using atomic absorption spectometry. The results show that the storage time did not have an effect on the contents of the selected elements in the eggs. Formula clause:hen egg, magnesium, copper, calcium, iron, zinc, atomic absorption spectrometry
