AWWA WQTC55091

The objective of this research was to evaluate the effect of temperature (25 degrees C and 45 degrees C) on odor intensity for geosmin, 2-methylisoborneol, TCN, n-hexanal, isobutanal, free chlorine, and 1-butanol. Odor intensity was measured by flavor profile analysis (FPA) and quantitative description analysis (QDA). Panelists were trained in flavor profile analysis (FPA) and evaluated water samples that contained odorants at either 25 degrees C or 45 degrees C. The higher water temperature resulted in an increase in odor intensity for some, but not all, concentrations of geosmin, 2-methylisoborneol, trans-2, cis-6-nonadienal, n-hexanal, free chlorine, and 1-butanol. The odor response of isobutanal was not affected by temperature changes. Includes 41 references, tables, figures.
