Abstract
This study was conducted in the laboratories of the Department of Food Sciences - College of Agriculture - Tikrit University from November - 2020 until January - 2021 with the aim of estimating the extent of contamination of pastries offered in the market with heavy metals and estimating the concentration of potassium bromate. The concentration of heavy metals (Cd, Cu, Ni) in pastries from different origins was estimated, as the cadmium concentration reached (<0.05 mg/kg) and did not exceed the internationally permissible limit. As for copper, its concentration ranged between (1.71 - 0.13 mg/kg) and did not exceed the internationally permissible limits. As for nickel, its concentration ranged between (0.16-0.95 mg/kg), and four samples of all studied samples exceeded the internationally permissible limits. This study showed that the potassium bromate concentration in pastries was between 0.21- (25.24 mg/kg) and all samples were within the internationally permissible limits.
