Abstract
Three groups of subjects, aged 18–25 years (Young), 36–45 years (Middle) and 56–65 years (Old) judged the similarity of pairs of pureed fruits and vegetables and rated the purees on 10 attribute scales. Multidimensional scaling of the similarity judgments produced four-dimensional solutions for each age group. Dimensions associated with tactile and texture attributes were found for each group. An hedonic dimension was indicated for Young and Middle groups, but sweetness ratings correlated with that dimension only for the Young group. Intensity was an important dimension for the Old group only. In general, the Young rated all the foods as having a more bitter flavor and sharper character than did the older ones. As a control, subjects also rated the similarities of foods by names only. Analysis of this scaling showed no age differences.
