Odor functions relating sensory

LINEAR AND POWER FUNCTIONS RELATING SENSORY ODOR INTENSITY AND CONCENTRATION... [Pg.30]

The first analysis of the ratings concerns their validity. Can panelists actually scale the relative sensory impressions of these odor stimuli by magnitude estimation Correct scaling of overall odor Intensity provides a validating measure of the panelist s sensory capabilities in this complicated study. Since panelists had the opportunity to scale unmixed odorants as well as the odor mixtures, and since the unmixed odorants comprised a graded intensity series (albeit presented at random in the set of 2k stimuli) it becomes a straightforward matter to determine whether panelists could pick out the k levels of each unmixed odorant, and scale them in the correct order of concentration. Panelists should do so. Table V shows linear and log-log (viz., power functions) relations between odor concentration in air, and rated overall odor intensity, for each pair of odorants in each study. Linear and power functions fit the data adequately. For power functions, the exponents are less than 1.0, confirming previously reported results in the literature. (2, 3)... [Pg.25]
