What are extruded products?

Extruded products are mostly manufactured without plasticizers (rigid), which includes all major products such as window and door profiles, siding, and pipes, and many other products such as blinds, clear compounds, fencing, interior profiles, planks, and sheets.

What are examples of extrusion?

Everyday examples of extrusion can be seen when toothpaste is squeezed out of a tube, icing is pushed out of an icing bag and “Playdo” shapes are made. Extrusion moulding of plastics is used to make any long shape that has a constant cross section.

What is extrusion in food industry?

Food extrusion is a form of extrusion used in food processing. It is a process by which a set of mixed ingredients are forced through an opening in a perforated plate or die with a design specific to the food, and is then cut to a specified size by blades.

Why is extrusion used in the food industry?

Extrusion enables mass production of some food, and will “denature antinutritional factors”, such as destroying toxins or killing microorganisms. It may also improve “protein quality and digestibility”, and affects the product’s shape, texture, colour, and flavour.

What are extruded snacks?

Extrusion cooking is the process extensively used for the production of snacks which are mainly produced from cereal flour or starches. Extruded snacks are normally high in calories and fat with low content of protein, fiber, and perceived as unhealthy food to many consumers.

Where is extrusion used?

Extrusion is a metal forming process in which metal or work piece is forced to flow through a die to reduce its cross section or convert it into desire shape. This process is extensively used in pipes and steel rods manufacturing. The force used to extrude the work piece is compressive in nature.

What is extrusion technique?

Extrusion technique is a process in food processing technology which combines several unit operations including mixing, cooking, kneading, shearing, shaping and forming. The extruder consists of a large, rotating screw tightly fitting within a stationary barrel, at the end of which is the die.

What are the disadvantages of extrusion?

Disadvantages of extrusion

• Variations in size of product.
• Product limitations because of only one type of cross section can be obtained at a time.
• High initial cost setup.

What is the principle of extrusion cooking?

Principle of Extrusion Cooking The raw materials are allowed into the extruder barrel and the screw(s) then convey the food along it. Further down the barrel, smaller flights restrict the volume and increase the resistance to movement of the food.

How is extrusion used in food processing?

Extrusion – New and Creative Food Items The extrusion process can take place under high pressures and temperatures or it can be just an easy non-cooking, and forming process. Use of extrusion in food production mainly assists in preserving the food products. Extrusion is used for making pet foods.
