Abstract

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.
