Resumen : Abstract: The objective of this study was to measure the sensory acceptability and obtain check-all-that-apply (CATA) responses for fruit-flavored powdered juices, with three different consumer segments: children and women who could be considered target populations, and a convenience sample of foodscience- related consumers (FSRC). The study was conducted with a total of 550 consumers in four cities: Alicante (Spain), Buenos Aires (Argentina), Manhattan (U.S.A.) and 9 de Julio (Argentina). The products were reconstituted powdered juices with the following flavors: apple, cherry, grape, grapefruit, orange and pear. Overall, FSRC consumers had the lowest acceptability scores for these products. Regarding CATA results, multiple correspondence analysis showed cherry and grape juices were associated to artificial-flavor and artificial-color, with the FSRC respondents being mainly responsible for the use of these descriptors. Pear and orange were considered to have natural-flavor and good-color, mainly by children and women. A generalized linear model was used to analyze the effect of “sample,” “city” and “consumer segment” on the percentage of checks given to each descriptor. The “consumer segment” effect was significant for nearly all descriptors, with FSRC checking samples differently to women and children
