Abstract
The invention relates to a process for the accelerated ageing of iris rhizomes consisting of irradiating after harvesting, all or part of the rhizomes with ionizing radiation with a view to accelerating the transformation of triterpenoids of the rhizomes into irones. After leaving them for several days, the irones produced are extracted and are ready for use, particularly in perfumes.
