Rapunzel speciality flours are partly produced from what is known as press cake. It is a residue from the gentle cold pressing of seeds into oil (e.g. when pressing hemp and linseed). The press cake contains a significantly lower proportion of fat than the raw materials, while retaining valuable ingredients. The flours are then ground from these pure press cakes. Speciality flours are also made from finely ground pulses (e.g. from lupin seeds and chickpeas) or from cold-pressed and ground coconut pulp.
