N2 - Flash Profile is a descriptive sensory analysis method, which gives freedom to the individual to decide on his/her own vocabulary to describe the sensory differences between products. The technique combines an individual vocabulary generation with inputs from the panel as a whole. The method is fast to generate a sensory vocabulary; often two vocabulary development sessions are sufficient. Subsequently, each subject uses his/her own vocabulary to rank all samples on their relative differences for the sensory attributes. The comparative assessment limits the method to the number of samples that can be tested. The method requires 5 to 10 experts or experienced sensory subjects, but does not need extensive training on the product properties, as needed in conventional sensory descriptive analysis methods. Although the method is fast and less laborious than conventional descriptive analysis methods, Flash Profile relies on subsequent alignment of the products×attributes space. This leads to a lower degree of precision especially when the attribute space is complex, e.g. when determining the flavour of foods. In cases where the attribute space is limited like for texture or sound, Flash Profile has the advantage of generating fast descriptive results on the main sensory differences between products. The ambiguous use of attributes in Flash Profile may have an advantage in cases where the generation of multiple attributes are desired, e.g. for vocabularies for communication with consumers.
