Abstract
Abstract A process of texturizing a mycelial fungal mass and resultant product is disclosed. The fungal mycelial mass containing 20% to 35% and preferably 23% to 33% solids in water is extruded through a die containing a foraminous member and a compression zone whereby a meat-like material is obtained.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
61 words
A method of texturizing a mass consisting essentially of fungal mycelia having reduced turgor and a solids content of between 20% and 35% by weight, consisting solely of the steps of passing the mass under pressure through at least one member containing a plurality of apertures whereby the mass is filamented and compacting the resulting filaments to form a textured structure.
Claim 2
Independent Claim
61 words
A method of texturizing a mass consisting essentially of fungal mycelia having reduced turgor and a solids content of between 20% and 35% by weight, consisting solely of the steps of passing the mass under pressure through at least one member containing a plurality of apertures whereby the mass is filamented and compacting the resulting filaments to form a textured structure.
Claim 3
Dependent Claim
20 words
The method as claimed in claim 1, in which the mass is passed in succession through a plurality of meshes.
Claim 4
Dependent Claim
16 words
The method as claimed in claim 2, in which the meshes have a different mesh size.
Claim 5
Dependent Claim
28 words
The method as claimed in claim 3, in which the mass is passed through two meshes, the upstream mesh having a smaller mesh size than the downstream mesh.
Claim 6
Dependent Claim
24 words
The method as claimed in claim 2 in which the mass is heated by shear action prior to passing through the mesh or meshes.
Claim 7
Dependent Claim
27 words
The method as claimed in claim 2, in which the mass is fed to the mesh or meshes under pressure within the range 100 to 200 p.s.i.
Claim 8
Dependent Claim
21 words
A mycelial mass having a texture analogous to the texture of meat or fish prepared by the method of claim 1.
Claim 9
Dependent Claim
14 words
The process of claim 1 wherein the process is carried out at ambient temperature.
