The therapeutic potential of broccoli has been highlighted by its function in the prevention of cancer, diabetes and other diseases. As a result, there is a great deal of interest in creating innovative functional foods supplemented with broccoli. In the extrusion-cooking process, raw materials based on potato mixes with the addition of fresh broccoli (Brassica oleracea L. var italica, Brassicaceae) were used to create new generation extruded snack pellets. A prototype single screw extruder-cooker with L/D=20 was utilized, and various processing conditions (screw speed 60 and 100 rpm, as well as either 32 and 36% levels of initial moisture content) were applied.
