Abstract:

The paper presents the results of the determination of essential (Fe, Zn, Cu and Se) and toxic (Pb and Cd) microelements in veal leg and in gammon, as determined through the Inductively Coupled Plasma - Mass Spectrometer (ICP-MS) method. Experimental results point to important contents of Zn (23.15 mg/kg and 16.30 mg/kg, respectively) and Fe (12.84 mg/kg and 5.97 mg/kg, respectively), appreciable contents of Cu (0.470 mg/kg and 0.335 mg/kg, respectively) and Se (0.074 mg/kg and 0.106 mg/kg, respectively) and very small amounts of Pb (0.031 mg/kg and 0.013 mg/kg, respectively) and Cd (0.016 mg/kg and 0.012 mg/kg, respectively), i.e. below maximum admitted toxicity limits. Mineral supply of veal and pork leg to the daily recommended diet estimated under experimental conditions show different values between 13.06% (in men and women) - for Cu in the pork leg and 72.34% (in women) - for Zn, in the veal leg. There are higher values of mineral supply in veal leg - 72.34% Zn (in women) and 52.61% Zn (in men) and pork leg - 50.94% Zn (in women) and 48.18% Se (in men and women). There were appreciable values of the mineral supply in the veal leg - 40.13% Fe (in men) and 33.64% Se (in women and men) and in the pork leg - 37.05% (in women). The supply in copper had the lowest values ranging between 9.31% (pork leg) and 13.06% (veal leg).

Keywords: meat, veal leg, pork leg, essential microelements, toxic elements, mineral supply, daily diet
