Free‐choice profiling (FCP) was carried out in order to investigate how naive consumers (who had never tried the product before) described and perceived passion‐fruit juice. This method allows participants to use their own attributes to describe and quantify food products and beverages. The study used four different samples of passion‐fruit juice, analyzed by 10 consumers in three replicates. The data were analyzed by using generalized Procrustes analysis. The first and second dimension accounted for 78.7% of the variance. The product consensus configuration revealed that assessors were able to reproduce samples’ description, and also to differentiate samples. Free‐choice profiling is a useful method for describing consumer perception of passion‐fruit juice.
