The objectives of this study were to determine the effect of extrusion cooking variables (feed
moisture, FM, 20% and 50%; screw speed, SS, 200 and 400 rpm) and storing of the extruded flours at
4 C for 24 h on the physicochemical properties, resistant starch (RS), pasting properties and antioxidant
capacities. Extrusion cooking at higher FM and lower SS increased the amylose content, which was
expressed in highest RS content.
