The use of alkaline sample solubilization and robust plasma
conditions led to accurate and precise determinations of Fe, Mg,
Mn, P and Zn in different types of meat samples. The method
applicability was verified by analyzing 7 meat samples, and the
results indicated that meat processing may be associated with a
possible increase in Fe contents and a decrease in Mg and P
concentrations.
Concerning the sample preparation, the dissolution with TMAH
was fast, simple and reproducible and does not require special
instrumentation such as microwave oven or strong acids for the
sample preparation. Furthermore, this procedure requires only
small amounts of sample and reagent, being less susceptible to
contamination or analyte losses. Due to its simplicity and the ICP OES multielemental capability, the proposed method shows good
promise for application to routine analysis (quality control)
of meat.
