Sensory Evaluation for Quality Designing the Fragrance

In research and development process, sensory evaluation is often performed for quality designing of the product that should be selected by target user. In sensory evaluation methods, semantic differential method is especially popular and useful by means of its quantitative property. So it is necessary that user's sensory structure made by ordinary terms is identical with manufacturer's one made by professional terms. But, in fragrance products, the gap of sensory structure between user and manufacturer is rather large, so user's sensory data by semantic differential method is insufficient for quality design by manufacturer, except preference data. Using eau de toilette, we propose PREFMAP that can analyze user's preference data to locate in sensory structure of professional terms.
