Abstract:
A method of preparing an extruded grain based product comprising the steps of:A. feeding an at least partially ungelatinized grain based material to a cooker extruder having at least one rotating screw, said cooker extruder including a barrel having a length to diameter (""L/D"") ratio, with the extruder barrel having an L/D of .ltoreq.6 and wherein the grain based material includes greater than about 15% to about 40% of a nutritive carbohydrate sweetening ingredient and has a moisture content;B. working the grain based material by rotating the screw to impart sufficient amounts of Specific Mechanical Energy (""SME"") to mix, heat and liquify the grain based material to a plasticized mass and to force the plasticized mass against a die plate at a pressure, wherein the screw rotational speed is at least 700 rpm and the residence time of the grain based material blend is .ltoreq.5 seconds; andC. forcing the plasticized mass through at least one die orifice in the die plate to obtain an extrudate.
