Abstract

A method for the detection and estimation of brominated vegetable oils applicable to the routine of soft drinks analysis is presented. Oils are extracted from the sample and then submitted to an alkaline combustion. The existing bromine is thus transformed in alkaline bromide. In an extremely simple device bromine is released through the reaction with sulphuric acid and potassium dichromate being then absorbed by
starch-iodide paper stríps producing a blue colour proportional to the original quantities of vegetable oils. By using this method ít is possible to detect till 10 parts per million of brominated vegetable oils in soft drinks.
