[Development of reference standards for preferential evaluation of odors].
The easy to handle and usefull portable standard for hedonic judgement of odors should consist of 5-6 microencapsulated various odorants to comparisons with evaluated odor in practice. In present study the 14 odorants were investigated on purpose to select the 6 ones. The group of judges was engaged and each odorant several times was classified as more or less unpleasant then one from 13 others. The set of individual preference relations was analyzed by two ways. First, the best acceptable sequence of all 14 considering odorants was computed and divided into 6 clusters. The single optional representative of each cluster was included in designed standard. The alternative approach bases on the best acceptable sequences of only 6 odorants from 14 considering ones. Thus, circa 50 primary solutions were obtained. Then the elimination from practical and medical points of view were executed and finally two follow standards are recommended: 1) anethole, 2) n-butyl alcohol, 3) acetone, 4) tetralin or indole, 5) isobutyric acid, 6) 2-mercaptoethanol.
