Advantages and disadvantages of extrusion processing
Extrusion processing has continued to gain popularity as one of the most energy efficient and environmentally friendly processes for a wide range of food products.Extrusion cooking is thus one of the preferred food-processing techniques due to its continuous process with high productivity, high temperature and short time cooking period while destroying both harmful microbial organisms and anti-nutrient enzymes, resulting in significant nutrient-retention products with longer shelf life.Furthermore, nutritious foods can be designed through extrusion to meet societal needs in addressing malnutrition and food and nutrition insecurity.

Disadvantages of extrusion food processing include a costly initial financial investment, and careful selection of process parameters such as moisture content, feed particle size, feed rate, screw speed, temperature, screw configuration and die shape to avoid reactive and harmful substance formation.Apart from the initial seed funding, the bulk of the disadvantage is purely technical know-how that can be obtained through short training courses. Thus the advantages of extrusion food processing far outweigh the disadvantages.
