Abstract

Barley as a cereal grain is very important for animal and human nutrition, being also used in food products technology for fermented or distillated beverages. It has very good nutritional properties for animals and human, being the forth ranks in cultivation and quantity production in the world. The flame atomic absorption spectroscopy (FAAS) is an analysis method for metals, but the laboratory procedure is essential for the final result. Our goal was to analysis the barley content from Banat area with FAAS method using direct determination from the solution after digestion and using a diluted solution. The direct determination for copper content in barley (in mg/Kg, presented as mean and SD) was 4.146±0.205; iron content was 25.657±0.583; manganese determination was 10.391±0.192 and zinc content was 17.911±0.565. The quantity of metals (in mg/Kg, presented as mean and SD) from diluted (5x) samples for copper was 4.463±0.403; for iron was 26.821±1.083; for manganese was 11.136±0.444; for zinc was 18.731±0.665. Comparative evaluation of the mineral content for copper, iron, manganese and zinc showed that the quantitative analysis of five times diluted samples present higher values for all analyzed minerals comparative with direct determination.
