What are the trace element profiles of different types of milk? This study investigates the content of trace elements of nutritional and toxicological interest in 90 samples of whole, low-fat, skim, condensed, evaporated, and powdered milks. Slurries were prepared with Triton X-100 and analyzed using electrothermal atomic absorption spectrometry.
The graphite oven's temperature–time program was optimized for each element. Concentrations of Pb, Cd, Al, Cu, Cr, Mn, Se, Zn, and Ni were determined. Concentrations of the pairs Cu–Cd, Mn–Cd, Mn–Cu, Zn–Mn, Ni–Cu, Ni–Mn, and Ni–Zn were significantly correlated (
This paper on trace element determination in milk aligns well with the scope of the Journal of Dairy Research, which focuses on research related to milk and dairy products. The investigation into the composition of different types of milk is highly relevant to the journal's audience.
