W pracy oznaczono zawartość fosforu ogólnego oraz magnezu i żelaza w wybranych krajowych przetworach mięsnych drobiowych, wieprzowych i wołowych oraz oszacowano, w jakim stopniu produkty te pokrywają dzienne zapotrzebowanie na te składniki mineralne u młodzieży w wieku rozwojowym oraz u dorosłych. Stwierdzono, że zawartość składników mineralnych jest bardzo zróżnicowana w zależności od gatunku wędliny. Wykazano, że 100 g badanych produktów pokrywa dzienne zapotrzebowanie na fosfor w ok. 25%, na żelazo w 11% oraz na magnez w 4%.

The aim of the study was to determine the content of phosphorus, iron and magnesium in meat products and to estimate their participation as a source of elements in diet. In the study we used 25 different kinds of meat products. The following kinds of meat products were studied: poultry, pork, beef, sausages. Magnesium and iron were determined by atomic absorption spectrometry. The concentration of phosphorus was determined by Scheel method. In all cases dry mineralization were used. It was shown that in meat products the content of phosphorus was from 79,4 mg% to 283,7 mg% (average 181,6 mg%): the concentration of iron ranged from 0,46 mg% to 2,8 mg% (average 13,0 mg%) and the content of magnesium was from 4,0 mg% to 22,0 mg% (average 13,0 mg%). The total amount of phosphorus calculated as P2O5 was in the range indicated in the norms for phosphorus in meat products. It was calculated that 100 g of meat product can cover 25% of recommended daily intake of phosphorus, 11% iron and 4% of magnesium.
