Awareness of the need to consider a consumption context when measuring the consumer's hedonic evaluation of a food product led researchers to investigate differences among responses given by consumers in different contexts. Previous studies measured the effects of evoking a consumption context, by using photographic pictures or a written scenario, on hedonic evaluations of consumers for food products. This study investigated the influence of evoking a consumption context, on hedonic evaluation of minimally processed cactus pear (O. ficus-indica) fruit, using pictures and memories of pleasant personal experiences. An hedonic scale method for measuring food preferences was used. Hedonic evaluation of minimally processed cactus pear fruit with sensory differences by a sample of consumers (n=150) when measured in the evoked context when having pleasant personal experience was compared with the one of another sample (n=150) measured outside context. Furthermore sensory evaluation of 'experts' (n=20) was accomplished. Differences in rating the sensory attributes were found among the three samples. To test hedonic differences between the two samples of consumers data sets were analyzed using ANOVA. Significant difference was observed between groups of consumers. Having obtained the rankings of sensory attributes correlation between consumers' and experts' evaluations was measured using the Spearman's rank correlation coefficient. This study highlights that the influence of a positive evoked context on hedonic evaluation of sensory attributes of minimal processed cactus pear that may influence consumer's purchasing behavior. Future research will explore the effect of evoking a consumption context comparing different fruit and whether this measure reflects product liking in actual consumption context.
