Vliv skladování na obsah vybraných nutrientů v křepelčích vejcích
Piskořová, Daniela
The aim of this master’s thesis was to determine the total contents of selected nutrients (magnesium, copper, calcium, zinc and iron) in quail eggs during the time of their storage. The contents of elements were measured in fresh eggs and then after first, second, third, eighth, fifteenth, twenty – ninth, forty – third and fifty – seventh day of storage. Theoretical part is focused on the production and importance of eggs, their creation and chemical composition. Additionally, this part deals with the more detailed characteristics of aforementioned elements and with their relationship to human nutrition. The practical part includes the results of measured contents of elements in whole egg, yolk and egg white. The analysis was carried out using atomic absorption spectrometry. The results show that the time of storing has no effect on the contents of selected elements in quail eggs.
