Evidence of regional differences in chlorine perception by consumers: sensitivity differences or habituation?
Chlorinous flavors are a leading cause of customers9 dissatisfaction with drinking water. Potential differences in chlorine perception were investigated by conducting sensory testing experiments in France and Spain to assess consumers9 sensory sensitivity (chlorine flavor detection threshold and supra-threshold intensity) as well as their liking of and acceptability for chlorinated solutions. In both countries, two groups of panelists were constituted based on their water drinking habits (tap vs. bottled water). Chlorine flavor detection threshold was found to vary depending on countries (0.17 mg/L Cl 2 in France and 0.56 mg/L Cl 2 in Spain). Taking into account that mean flavor detection t…
Evidences of regional differences in chlorine perception by consumers: sensitivity differences or habituation?
Résumé du poster présenté.; Chlorinous flavors are one of the leading cause of customers’ complaints and dissatisfaction with drinking water. To investigate potential regional differences in chlorine perception, sensory testing experiments were conducted in France and in Spain to assess consumers’ sensory sensitivity (chlorine flavor detection threshold) as well as their liking and acceptance for chlorinated solutions. The chlorine flavor detection threshold was found to vary depending on countries (0.17 mg/LCl2 in France and 0.56 mg/LCl2 in Spain). According to the relation found between chlorine practices and average flavor detection thresholds, it is likely that habituation may support o…
