- Opis:
- The aim of the study was to determine the chemical composition of pig meat, liver and kidney in terms of mineral elements, and to establish the relationships between selected macro- and microelements. Twenty organically raised pigs [Złotnicka Spotted and F1 (Polish Large White × Polish Landrace)] were investigated. At the end of fattening (100-108 kg of body weight), the animals were slaughtered and the following tissues and organs were sampled from each pig: muscle longissimus lumborum, liver, and kidney. The samples were freeze-dried and digested in an Ethos Plus microwave system. Mineral content of the prepared samples was determined by means of a Unicam Solar 969 atomic absorption spectrometer. Longissimus lumborum muscle proved to be rich in macroelements as 1 kg of fresh tissue was found to contain as much as 282.34 mg magnesium, 3 668.41 mg potassium and 329.35 sodium. Among the analysed microelements (Zn, Cu, Mn and Fe), the presence of only zinc and iron (16.13 and 0.02 mg kg-1 of fresh tissue, respectively) was detected in the muscles. Liver samples were characterised by the highest levels of Zn (64.09 mg kg-1), Mn (3.37 mg kg-1) and Fe (0.48 mg kg-1). The mean content of Cu in 1 kg of fresh tissue did not exceed 7.42 mg. The macroelements determined were Mg (180.89 mg kg-1), K (3 082.04 mg kg-1) and Na (744.25 mg kg-1). Kidneys were most abundant in Cu (9.52 mg kg-1) and Na (1 404.08 mg kg-1). In addition, they also contained zinc (24.62 mg kg-1), manganese (2.25 mg kg-1), iron (0.11 mg kg-1), magnesium (202.14 mg kg-1) and potassium (2 541.63 mg kg-1).
