A method for the purification of lecithin, comprising the steps of: a. reducing the viscosity of lecithin to a viscosity of less than about 10 Pa.s; then b. mixing the lecithin with granulated active carbon; then c. separating the lecithin from the granulated active carbon and recover purified lecithin. Lecithin substantially free of poly-aromatic hydrocarbons, and a food or feed product comprising said lecithin. Procédé de purification de lécithine, comportant les étapes consistant à: a) réduire la viscosité de la lécithine à une viscosité inférieure à environ 10Pa.s; puis b) mélanger la lécithine à du charbon actif en granulés; puis c) séparer la lécithine du charbon actif en granulés et récupérer de la lécithine purifiée. La lécithine obtenue est sensiblement exempte d'hydrocarbures poly-aromatiques. Un aliment ou un produit d'alimentation comportant ladite lécithine est également décrit.
