Loterre: Extrusión: texturisation

In case of proteinaceous substrates texturization involves a restructuring of protein molecules into a layered crosslinked mass which is resistant to disruption upon further heating and/or processing. The large unfolded protein molecules align themselves in the direction of flow in the screw channels and void space behind the die. Flow is necessary to achieve alignment of the unfolded molecules and with increased temperature to 140-160°C, chemical crosslinking reoccurs to give the layered, fibrous structure which simulates meat.
