For more than 35 years, the CVG has made available a unique tool in the country which provides a structure that wants to innovate, diversify or solve a specific problem with access to a set of services and skills ranging from concept validation to marketing innovating products.
Innovating project management and studies
Support for innovation projects, expertise on markets, personalised strategy consulting, financial preparation for programmes.
Research and development under contract
Technical and economic feasibility studies on all types of plant raw materials, by-products or fractions, and in terms of extraction, purification and chemical or enzymatic modification of plant biomass.
Industrial transfers, putting on the market, defining industrial tools
The size of the equipment at CVG allows us to perform the extrapolations that are needed to produce pre-series, intended for validating target markets (new food ingredients, active ingredients in cosmetics, parapharmaceuticals, nutraceuticals or fine chemistry). The production campaign possibility also makes it possible to validate the industrial cost prices and the overall robustness of a chain of unitary processes, before the final definition of a production workshop.
Forming specialty products
Active substances and ingredients, extracts, nutraceuticals (extraction / purification, drying).


Food technology institute (ITAI).
Technological ressource centre (CRT).
Research structure under contract (SRC)
Approved for research tax credit.
Accredited training organisation (Approval no.:
ISO 9001 Certification for all of the activities at CVG (studies, research & development, transfers).


Cosic (Strategic orientation committee on chemical industries).
General directorate of customs and indirect rights.
BPI France.


The Extractis site is equipped with a main hall devoted to fractioning and to the "dry route" process, as well as Atex extensions (solvent purification).
The analytical and pilot equipment make it possible to work on all of the unitary operations in fractioning, purification, chemical and enzymatic modification of molecules and plant constituents, on a scale ranging from the gram to several tonnes for transfer operations and industrial validation.
The site also has the required utilities (steam, softened water, osmosed water) in order to work on all of the process parameters in actual industrial conditions.
