Limitations and perspectives in the use of Flash Profile

Despite its enormous advantages. Hash Profile cannot be used to answer all our sensory issues, and we are now facing some limitations with this methodology. 

Rapid Sensory Profiling Techniques and Related Methods 

A second limitation of the comparative evaluation methodology is that it is rather difficult to compare results from different sessions obtained at different times. Indeed, with Flash Profile the products are ranked in order of increasing intensity for each descriptor, but they are not given any absolute intensity scores on a scale. Contrary to conventional descriptive methodologies, it is thus much more difficult to correlate several sensory maps. Two maps can be qualitatively compared, but combining data into one map is not straightforward and will require specific calculation techniques. The free vocabulary also adds to this complexity and to the difficulty in comparing data from different exercises. 

The fact that the evaluations are based on ranks and not on intensity scores can finally lead to difficulties in communicating the results we can always say that Product B is softer than Product A, but how much softer is a recurring question. It could only be answered by including standard products in the evaluations and by using intensity scales.
