A method for preparing coated binder units, wherein the coated binder units comprise a core of binder coated with a layer of coating material, is disclosed. The method comprises steps of: (a) co-extruding the binder and the coating material, thereby producing an extrudate wherein the binder is coated with a layer of coating material; and (b) optionally, shaping the extrudate, into coated binder units.
