Left: resin; center: rosin; right: turpentine oil

After harvesting, the resin takes the form of a homogeneous mixture. Its distillation makes it possible to obtain two products: rosin and turpentine oil. The objective of extraction is to isolate and sample these compounds accurately. In other words, it is a question of having the finest possible selectivity. The second objective is not to alter the molecules and thus take full advantage of its qualities.

Forest of Epiceas in the north-east of France.

The objective of the project is to provide preliminary information, both bibliographic and ethnological, chemical, genomic, biochemical, technical and economic, in order to assess the relevance of restarting the resin extraction of forest species other than maritime pine to supply the growing societal demand for terpene biomolecules.
