Abstract
The aim of this study was to examine the effect of heat treatment on the content of iron (Fe), zinc (Zn), copper (Cu) and magnesium (Mg) in muscles and liver of cattle depending on the fattening system from which the animals originate. The study was conducted on samples of muscle meat (round and chuck) and liver of cattle aged 9 to 12 months that were fattened extensively (n = 12) or intensively (n = 12). Each sample was divided into two equal parts, one of which was analyzed in the raw state and the other after heat treatment by boiling in water at 100°C. The results are expressed in dry matter of meat. The content of ash (mineral residues) in thermally treated samples was reduced compared to raw samples, but this was not accompanied by significant changes in the content of Fe, Zn and Cu in muscle meat, nor changes in Zn and Cu in the liver. Heat treatment led to a decrease in Mg content in all examined batches of meat (by 40-50%), and a decrease in Fe content occurred only in the liver (by 25-42%). The effect of heat treatment on the content of tested minerals in muscles and liver was independent of the fattening system, although differences in the fattening system were evident for all tested minerals, except for Fe. The Zn content in beef round muscles from extensive fattening was lower, and the Cu content was higher compared to samples from intensive fattening system. In contrast to round muscles, the Cu content in the liver was higher in cattle from intensive fattening. In all examined batches of meat from extensive fattening the Mg content was significantly higher than in beef from intensive fattening system.
