The apple (Malus domestica) is a continental fruit tree whose fruit ripens from early summer to winter. More than 6000 varieties are known worldwide. It belongs to the Rose family (Rosaceae). In Croatia, it is considered as an important crop as it covers 22 % of the fruit-growing area. As a food, it is recommended as part of the daily diet due to its extremely high nutrient content. The importance of this study is to provide consumers information on the sales channels where they can find apples with the highest mineral content, while the aim is determination the nitrogen and magnesium content of apples on the Zagreb market and calculation what percentage of the daily nitrogen and magnesium requirement is covered by the investigated samples. The hypothesis of the work is that the content of nitrogen and magnesium in apples from stores with organic products is higher than in apples from retail chains and markets. Sampling of apple fruits was carried out on October 23, 2023 in the city of Zagreb in three markets, three retail chains and three stores with organic products. The sampling was carried out in triplicate. The results show that the highest nitrogen content (0.42 % N in dry weight) were found in apples from retail chains, while almost the same results were obtained for magnesium (0.03 % Mg dry weight) in all sales channels. The highest nitrogen content (69,12 mg N/100 g in fresh weight) was found in apple samples from markets, while the magnesium content (5,77 mg Mg/100 g in fresh weight) was slightly higher in stores with organic products. The apple is a food that contains small amounts of nitrogen and magnesium, and these amounts do not correspond to the daily requirement recommended for absorption in the body, but nevertheless there are many other benefits that make its daily consumption recommendable.
