With the process for producing potato based expandable pellets, an intermediary product is manufactured that is capable of being stored for up to about six months. These pellets can be later expanded into a food product, particularly a potato based snack product that has improved flavor qualities and increased oil pick up. To form the pellets, a potato meal is passed through a twin screw extruder at a relatively low extruder rotational speed, which increases the residence time and the volume of bed pack in the extruder while decreasing shear. The extrudate produced is then split into ribbons that are subsequently perforated. These ribbons are then formed into shaped pellets.
