What purpose do perceptual maps serve in sensory evaluation?

Perceptual maps serve to visually represent relationships between products based on sensory attributes. This graphical tool allows evaluators to plot products in a two-dimensional space according to different sensory characteristics, such as taste, aroma, texture, or overall quality. By placing products on the map, it becomes easier to see how they compare to one another and to identify clusters of similar products, as well as gaps in the market where new products could be developed. This visualization helps in understanding consumer preferences and guiding product development by emphasizing the sensory dimensions that matter most to consumers.
