Bromate content in thirty different brands of bread baked in Port Harcourt Metropolis Rivers State, Nigeria

Abstract

This work considered the presence of potassium bromate in thirty different bread brands baked in Port Harcourt metropolis of Rivers State, Nigeria. The analysis was carried out in two locations of South and North, Port Harcourt metropolis with fifteen samples for each. The study revealed the presence of potassium bromate in all the samples 0.025-0.058 mg/Kg and 0.011- 0.059 mg/Kg for south and north respectively. It also revealed the mean to be 0.048±0.010 mg/Kg for south and 0.041±0.008 mg/Kg for the north, Apart from one of the samples (B10analyzed, the concentrations ranged from), all the values were above the allowed limit by NAFDAC. The result showed that both locations have bakeries that use bromate content higher than permissible limit. It is therefore advisable that consumption of bread from the study area may be of harmful effect due to bioaccumulation over a period of time.
