ResumoIntensity and persistence of sweet taste of sugars (glucose, fructose, xylose and sucrose) and polyols (sorbitol, xylitol) were determined in ethanol-water mixtures using a sensory measuring unit for recording flux (SMURF) device. In all cases sweetness intensity and persistence were decreased when ethanol concentration was increased from 10% to 30%. Assessing intensity/time responses for varied (from 2.3% to 9.2%, w/v) concentrations of d-glucose, d-fructose and sucrose in 5% ethanol mixture shows that persistence is more affected by the presence of ethanol than intensity. These results are interpreted by the solution properties in the ethanol-water binary solvent.
