Bromate and trace metal levels in bread loaves from outlets within Ile-Ife Metropolis, Southwestern Nigeria
Bread loaves randomly sampled from nine outlets and bakeries within Ile-Ife were analysed to determine their safety levels for human consumption with respect to bromate and trace metal contents. Bromate determination was carried out via spectrophotometric method while trace metals in the digested bread samples were profiled using Flame Atomic Absorption Spectrophotometer. Bromate levels in the ...
متن کاملMeasurement of bromate in bread by liquid chromatography with post-column flow reactor detection.
This method is suitable for the determination of bromate residues in a variety of baked goods. The peer-verified method trial was performed on white bread, multigrain bread, and coffee cake spiked with known levels of potassium bromate. The analytical portion is extracted with deionized water to remove bromate from the bulk of the baked product. The aqueous extract is carried through a series o...
متن کاملSpecific determination of bromate in bread by ion chromatography with ICP-MS.
A sensitive method for detecting bromate in bread by ion chromatography with inductively-coupled plasma mass spectrometry (IC/ICP-MS) was developed. Bromate was extracted from bread with water. The clean-up procedure included a 0.2 micron filter, a C18 cartridge for defatting, a silver cartridge to remove halogen anions, a centrifugal ultrafiltration unit to remove proteins, and a cation-exchan...
متن کاملEffects of Reducing Agents and Baking Conditions on Potassium Bromate Residues in Bread
Potassium bromate is a well known dough conditioner that has been used for many years in breadmaking around the world. It is used to improve dough-handling properties, oven rise, texture, and loaf volume and to control bread properties affected by changes in wheat qualities between crop years. Potassium bromate is a slow-acting oxidizing agent. It reacts until the end of the make-up stage, mode...
متن کاملClosed-form analytical solution procedure for element design in D regions
This paper presents a novel procedure for solving the equations system of the rotating crack model used for reinforced concrete. It is implemented in the programme NonOPt where it is used to optimise the reinforcement design of D regions. The procedure is based on solving explicit closed-form relations without the need to incrementally increase the applied loads. The solution procedure is based...
