Analysis and Expertise
Studies and Services analysis unit
You wish to
A guarantee of food safety
To finely characterize the fat of your products
Sensory analysis of your oils and proteins by an expert jury
Study the rheological behaviour and texture of your fatty phases
.
The Analysis and Expertise Department mobilizes a high-level of expertise on fatty substances(COFRAC accreditation on a large number of analyses offered).
It is also a valuable operational capacity in the event of a health crisis for all industrial players.

Recognized expertise in
- fine characterization of fats and purity controls
- search for contaminants to guarantee food safety(mineral oils, pesticides, solvents, hydrocarbons, phthalates, etc.)
and for undesirable neoformed products (trans-fatty acids, oxysterols, etc.) - assessment of spoilage with checks for conformity, oxidation stability and rancidity
- sensory analysis (oil expert panel)
- studies of the rheological behaviour and texture of fats
From Services on all types of products including fatty matrices


Fat extraction adapted to the matrix - Fat content: all matrices / formulation
(Soxhlet, Hydrolytic, Non-altering) - Free fat content
