Compositional Investigations of Some Romanian Cereals

Abstract

Wheat, barley, rye, oat as grains, bran, and flour are the most consumed cereals by humans. Cr, Fe, Co, Ni, Cu, Zn, Cd, and Pb, were determined in this paper, by inductively coupled plasma atomic emission spectrometer (ICP-AES) and FTIR analytical technique. By ICP-OES, the concentration of the minerals has been identified and calculated, while by FTIR, the main compounds are identified, as follows: lipid lignin and carbohydrate. The highest Fe content was detected in barley flour (61.233 ± 0.409 mg/kg), whereas the lowest content was determined in what flour (7.850 ± 0.029 mg/kg). Furthermore, the highest and lowest Cr contents were found in flour, too: oat, barley, and rye, respectively.
