Abstract

Food additives: are compounds that are added to food to maintain flavor or improve its appearance, taste, or other sensory attributes. Potassium Bromate: Bakers regularly employ potassium bromate (KBrO3) as an oxidizing agent to improve bread quality. It improves gas retention and product volume by maturing flour and strengthening the gluten network. IARAC in1999 classed it as a category 2B carcinogen (probably harmful to humans). The main aim of this study is determination the contents of potassium bromated in some Bread and Pastry products collected from different cities in Libya. Sampling: Total different fifty samples of bread and pastry products were collected randomly from local markets from some Libyan cities. Mythology: The absorbance of the samples was measured at 620 nm using a UV-V by spectrophotometer. Analysis was done on three replicates for each of the samples. Results: All of the 50 samples show a high level of KBrO3 ranged from (2.632-16.54µg/g). Discussion: The results of the contents of potassium Bromate in the studied samples showed wide variations. Potassium bromate was found in all samples and higher than the limits which set by World Health Organization (WHO), and Food and Drug Administration (FAO). Conclusion: According to the obtained results in this study there is wide variations in the potassium bromated contents, where some of samples contained high values given by WHO and FAO presimible limits. There are some heavy metals values higher than the WHO and NHMRC guide lines for human consumer
