Extrusion Processing: A Versatile Technology for Producing …

The word extrusion means shaping a material or a blend of materials that can be plasticized (able to be melted and become fluid-like), and is pumpable by forcing through a restricted opening or die.. The versatility of the process is evident in its ability to produce different types of foods. The power of the process can be further appreciated by its ability …
