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.
