The present invention refers to an important step in the processing of bioproducts, as is the case of essential oils rich in safrole. The invention here described refers to the enrichment of safrole from mixtures containing safrole resulting from the extraction of safrole from plants which are rich in this component. The enrichment process uses the operations of adsorption and desorption in an activated charcoal bed. The adsorption operation is followed by desorption using an alcoholic solvent which contains then, the enriched, desorbed essential oil. This method employs simple and easy-to-handle equipments, as well as allows, due to a low time consumption and low financial cost, the enrichment to reach a higher safrole content than the currently employed methods. La présente invention concerne une étape importante dans le traitement de produits biologiques, comme dans le cas d'huiles essentielles riches en safrole. La présente invention concerne l'enrichissement du safrole à partir de mélanges contenant du safrole résultant de l'extraction du safrole de plantes qui sont riches en ce composant. Le procédé d'enrichissement met en oeuvre des opérations d'adsorption et de désorption dans un lit de charbon actif. L'opération d'adsorption est suivie d'une désorption utilisant un solvant alcoolique qui contient alors l'huile essentielle désorbée enrichie. Ce procédé emploie du matériel simple et facile à manipuler, de même qu'il permet, du fait d'une faible durée et d'un faible coût, à l'enrichissement d'atteindre une teneur en safrole plus élevée que les procédés actuellement employés.
