Meat & Fish Process High-moisture extrusion processing can be used to create plant-based meat and seafood textures. During extrusion, proteins undergo thermal and mechanical stresses by heating of the barrel and shearing of the screws. As a result, protein structure is altered leading to the formation of soluble and/or insoluble aggregates. By attaching a long cooling die to the end of the extruder (as shown in the photograph on this page), proteins can be aligned in the flow direction forming an anisotropic protein network.
