Extrusion is referred to as a system of propelling mixed ingredients out through a small opening, called a die, to form and shape the materials. The formed products are then called extrudates. The first extruders for food processing were piston and ram-type extruders for processing meats and sausages (Harper 1981). Food extrusion is a part of the food processing process which aids in developing food a specific way, and later bringing it to defined sizes majorly with the help of blades. Breakfast cereals, confectionery products, baby foods, and different kinds of pasta make important applications of the food extrusion mechanism.
