A foodstuff having a heterogeneous composition and a fibrous structure in the form of coherent filaments of substantial length, is prepared by simultaneously crushing and compressing whole or coarsely broken animal, fish or crustacean raw material in a phase separation press, with at least one advancing punch in a closed chamber filled with the raw material under a pressure sufficient to compress and masticate soft foodstuff matter and crush hard matter in the raw material without substantially destroying the cohesion of the desired food components of the raw material and to extrude the masticated soft matter from the press, the closed chamber and/or punch being provided with exit channels through which the masticated matter is extruded the masticated soft foodstuff matter is extruded from the press to obtain a product having a hetetogeneous composition and containing the desired food components in the form of coherent filaments of substantial length, the undesirable components of the raw material remaining in the portion resisting to extrusion. The method of the invention enables to obtain a foodstuff in which the food components have several millimeters long, which gives the product a good aspect for appetency. |
