Abstract: | "Although esters were important odorants in light aroma-type liquor, it was still puzzling that sensory interaction between esters made the odor quality of light aroma-type liquor outstanding. The aim of the paper was to investigate perceptual interaction among esters. The odor thresholds of eighteen esters and 35 binary mixture were determined by a three-alternative forced-choice procedure. The relationship between odor threshold and carbon chain length of homologous ethyl esters was investigated. Moreover, 31 binary mixtures present either a synergistic effect or additive action. Furthermore, odor quality and odor intensity were determined by p/tau plot and sigma/tau plot, respectively. From the p/tau plot, an ideal sigmoidal function for odor quality was obtained. From the sigma/tau plot, for all 120 binary mixtures, just 9 mixtures were in the hyper-additivity area (sigma?ª+>?ª+1.05), and two were in the so-called perfect additivity area (0.95?ª+ª+sigma?ª+ª+1.05). Almost one half (48%) showed compromise level. Finally, a significantly difference was observed by flash gas chromatography electronic nose (p?ª+ª+.05). Sensory analysis revealed that a mask effect of fruity note was occurred by adding ethyl phenylacetate at various levels (100, 2500, 58,000?ª+ppb) to the fruit recombination and an enhancement effect of floral note was reported by adding phenylethyl acetate at low (1400?ª+ppb) or high level (11,500?ª+ppb). It was noticed that sweet note was significantly enhanced by adding phenylethyl acetate at peri-threshold (3200?ª+ppb)" |
