Detection of Residual Potassium Bromate Concentrations in Cake Samples Sold at Kano State, Nigeria

Abstract

The level of residual potassium bromate concentrations of cake samples sold within the three senatorial districts of Kano State was evaluated. The residual potassium bromate level was determined following standard Spectrophotometric protocols. Data for residual potassium bromate concentrations in cakes sold within the three senatorial districts of Kano State was expressed as Mean ±SD and analyzed using one-way analysis of variance ANOVA. Values were considered significant when p<0.05. Correlations were carried out for the mean levels of residual potassium bromate concentrations of the three senatorial district. A total of four hundred and fifty (450) cake samples from three selling points (markets, shops and bakeries) of the three senatorial districts of Kano State were analyzed. The mean residual potassium bromate levels in the samples analyzed ranged from 24.8 - 177.5mg/kg. Statistical analysis showed significant difference (P=0.02) between Kano Central Senatorial District and the two other Senatorial Districts of Kano State. Percentage (%) Compliance and Defaulters of Potassium Bromate in the Three Senatorial District of Kano State shows the highest potassium bromate defaulters to be found in Kano Central 51(34%) while the highest bromate compliance was found in Kano North 144 (96%). The results revealed that most of the cake samples obtained from Kano Central Senatorial District had
