Extrusion is defined as which process?

• A. Pushing Material Through a Hole by Applying Pressure
• B. Cooking Food with Direct Heat
• C. Drying Material by Evaporation
• D. Packaging Material in Sealed Bags

Answer: (A)

Extrusion is the process of forcing material through a die or opening under pressure, typically with heat and shear, to shape and often cook the product as it forms. The essential idea is pushing material through a hole by applying pressure, usually with a screw-driven extruder that can also heat the material. This distinguishes it from simply cooking with direct heat, drying by evaporation, or packaging the product, all of which don’t involve forcing material through a die to create a shaped, continuous product. Extrusion is widely used for foods like pasta, snacks, cereals, and texturized protein products, where the die determines the final cross-section and texture.
