Abstract
Abstract A process of continuously forming tender textured protein structures is disclosed. The structures are formed from an aqueous slurry of a proteinaceous material having a solids content of up to about 35 percent by weight. The proteinaceous slurry is formed into textured filaments or fibers by continuously heating the slurry under pressure and cooling the slurry.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
13 words
The process of claim 1 wherein the proteinaceous material is solvent extracted soybean.
Claim 2
Dependent Claim
19 words
The method of claim 1 wherein the slurry is processed at a pressure between about 50 and 5000 psig.
Claim 3
Dependent Claim
15 words
The process of claim 1 wherein the slurry is heated with an injection heat exchanger.
Claim 4
Dependent Claim
29 words
The process of claim 1 wherein a source of phosphate ion is added to the treated slurry in proportions of about 3-4 percent by weight of the proteinaceous material.
Claim 5
Dependent Claim
9 words

Claim 6
Dependent Claim
200 words
A process of continuously forming elongated tender protein filaments from an oilseed proteinaceous material comprising: a. forming a slurry of an oilseed proteinaceous material containing off flavors with water, the slurry having a proteinaceous solids content of between about 20 and 35 percent by weight, b. treating the slurry by raising the pH of the slurry to place the proteinaceous material in a sufficiently reactive form to produce elongated protein filaments to between about 4 and 11 with hydroxides and salts of polyvalent linking agents selected from the group consisting of calcium, aluminum, magnesium, and adding a source of phosphate ion to the slurry, the source of phosphate ion being added in proportions of about 3-4 percent by weight of the proteinaceous material, c. continuously conducting the treated proteinaceous slurry under pressure suitable to produce elongated tender protein filaments through a heat exchange zone to heat the slurry to a temperature between about 240* and 315* F. for a period of time sufficient to produce elongated tender protein filaments in the slurry and continuously removing the heated slurry and elongated protein fibers through an orifice to a collecting zone, and d. recovering tender elongated protein filaments from the protein slurry.
Claim 7
Dependent Claim
14 words
The process of claim 7 wherein the source of phosphate ion is trisodium phosphate.
Claim 8
Dependent Claim
9 words
The product produced by the process of claim 7.
