2. Principles of sensory metrology
2.1 Sensitivities involved
Visual sensitivity
It is due to the excitation of receptors located on the retina (cones and rods) and is probably the best-known and best-understood sensitivity: we all know what a visual sensory image is. In fact, several people can "share" the same visual image at the same time, so that it will generate, almost automatically, a semantic or artistic communication.
the appearance, shape, color, shine and transparency of a food or drink are generally the first sensory perception.
Olfactory sensitivity
A large proportion of the organoleptic...

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...
