Status of macroelements in leek on the Zagreb market

Popis výsledku v původním jazyce

Leek (Allium ampeloprasum L. ssp. porrum) is a plant of the Alliaceae family. It is one of the most grown vegetables in the world. It has an important place among vegetables because of its benefits for human health. A growing problem faced by consumers is the lack of information about the nutritional composition of fruits and vegetables. Macronutrients are needed in the human body in larger quantities than micronutrients, so it is important that consumers be informed about their composition in the food they consume. The aim of this study was to determine the content of macronutrients in leeks offered on the Zagreb market. Sampling was conducted across nine purchase points in the city of Zagreb, including three markets, three retail chains and three organic product shops. The average samples were dried at 105 degrees C, then ground and homogenized. Nitrogen was determined by the Kjeldahl method, and after digestion with concentrated HNO3 and HClO4 in a microwave oven, phosphorus was determined by spectrophotometry, potassium by flame photometry, and calcium and magnesium by atomic absorption spectrometry. Dry matter (DM) in leek ranged from 8.38 to 9.97%. The determined content of macroelements in the dry matter of leeks ranged 2.32-3.07 g N 100 g(-1) DM, 0.35-0.41 g P 100 g(-1) DM, 2.76-3.75 g K 100 g(-1) DM, 0.40-0.44 g Ca 100 g(-1) DM and 0.12-0.17 g Mg 100 g(-1) DM, while on a fresh matter basis the values ranged 272.67-386.67 mg N100 g(-1) fresh matter, 40.33-51.33 mg P 100 g(-1) fresh matter, 320.67-474.33 mg K 100 g(-1) fresh matter, 46.67-56.00 mg Ca 100 g(-1) fresh matter and 14.33-17.67 mg Mg 100 g(-1) fresh matter. By consuming 100 g of analyzed leeks, it is possible to meet 2.7-3.9% of daily needs for nitrogen, 5.8-7.3% of daily needs for phosphorus, 16.0-23.7% for potassium, 5.8-7.0% for calcium, and 3.8-4.7% of daily magnesium needs.
