Investigation of an iodine-like taste in herring from the Baltic Sea
conference paper
Marinated herring from the Baltic Sea was found to have an offensive odor and taste described as iodine-like and phenolic. Fat isolated from herring was found to contain this taint. The volatiles were isolated from the fat, using a molecular distillation and were subsequently fractionated by gas chromatography. A fraction containing the taint was obtained and submitted to mass spectrometric analysis to identify compound(s) of interest. By this procedure, the tainted herring was found to be contaminated with o-bromophenol. This compound was not found in good quality herring or only at a concentration level below its odor and flavor threshold values. The odor and taste thresholds of this compound and its isomers were determined. Refs.
