Abstract: The present invention relates to a method of treating a raw feed material, the method comprising a grinding step, an enzymatic treatment step, and a drying step, wherein the raw feed material is ground to obtain a meal in the grinding step, water is added and mixed into the meal to obtain a mixture, which is then subjected to an enzymatic treatment step with an enzyme preparation, to obtain an enzymatically treated mixture. The enzymatically treated mixture is dried in the drying step. The grinding process is adjusted in such way as to deliver a meal that has a particle size, measured as d50, between ?100 ?m and ?1000 ?m, whereas water is added to achieve a total water content of between ?15% w/w and ?40% w/w.
