Comparison of two sensory profiling techniques based on consumer perception

Eight chocolate milk desserts with different formulation were evaluated by two groups of consumers. Fifty consumers evaluated the samples and indicated their overall liking and answered a CATA question. Meanwhile, 40 consumers elicited up to four words to describe the desserts and completed a projective mapping task. Projective mapping and the check-all-that-apply question provided very similar sensory profiles for the evaluated milk desserts. Differences in the sensory characteristics of the samples were explained by differences in their formulations, which suggest the validity of the sensory profiles given by consumers. Projective mapping and the CATA question consisted on valuable tools to understand their perception of the sensory and hedonic characteristics of the desserts. These methodologies could consist on useful and interesting complimentary techniques to trained assessors' data, being CATA question easier to understand and less time consuming for consumers.
