3. Sensory response characteristics
The characteristics of a sensory response are very different from those of an instrumental response. They are due both to the sensory signal at the origin of the response and to the activity of the subjects, placed under stress, who provide the response.
3.1 The three components of sensory response
A sensory signal (always) has three components: a qualitative component (this drink is an orange drink), a quantitative component (the orange taste of this drink is weak) and a hedonic component (I like this orange drink).
The qualitative component is certainly the most difficult to express, if not to identify, when we only have the sensory inputs (and not the commercial variables) to apprehend it. It corresponds to the...

Research organizations
In addition to the ACTIA centers, which develop applied research activities in the field of sensory metrology alongside their activities as service providers, most agri-food schools, notably Enitia (Nantes), Ensbana (Dijon) and Ensia (Massy), have a sensory evaluation research group.
At INRA, the most active laboratories in the sensory field are certainly those at...

Service providers
Numerous organizations offer custom assessments in the discriminative, descriptive and hedonic fields.
A number of these centers, which come under the auspices of technical centers or CRITTs, are members of ACTIA (Paris). ACTIA has drawn up a Guide to Good Practice (see above) for clients of ACTIA centers who "sell" sensory evaluation and who undertake to comply...
