Extrusion Processing

Extrusion is a very common processing technology used in the food industry to produce direct expanded snack foods, cereals, and pet foods, among other products. Extruded products are typically made by utilizing a raw material, often flour, and subjecting it to high temperatures while also creating a high shear and high pressure environment using rotating screws.

This introductory course will provide information about the extrusion processing systems, extruder parts, basic heat and mass transfer, extruder screws and dies, food ingredient functionality and food product development with extrusion. The course will provide practical examples of product development with extrusion using ingredients.

Extrusion is a very widely used technology in the food industry. Some of the common food products made with extrusion technology include snacks, breakfast cereals, flat breads, bread crumbs, pellet products, textured vegetable proteins and many others.
