Grove vezelsamenstelling

Grove vezelsamenstelling bevattende grove vezels van graanbostel, daardoor gekenmerkt dat de grove vezelsamenstelling ten minste 65 gewichtspercentage (gew%) onoplosbare hoog molecuulgewicht dieetvezels (onoplosbare HMWDF) en minder dan 15 gew% proteïne van het totale gewicht van de grove vezelsamenstelling. The invention pertains to a method for processing aleurone-containing plant-based material characterized in that the method comprises the steps of: i) optionally washing the aleurone-containing plant-based material, whereby protein is separated from the aleurone-containing plant-based material to obtain a first protein-containing liquid (22) and the aleurone-containing plant-based material: ii) optionally removing water from the aleurone-containing plant-based material to obtain an aleurone-containing plant-based material suspension (2) containing 1 to 30% by weight of the aleurone-containing plant-based material, based on the total weight of the suspension, and obtaining a second protein-containing liquid (23); and ill) treating the suspension of the aleurone-containing plant-based material (2) containing 1 to 30% by weight of the aleurone-containing plant-based material with a high shear mill (3) to at least partially release protein encapsulated in the aleurone cells, and to obtain a ground aleurone-containing plant-based fiber (4).
