Abstract
Abstract A process for preparing a protein food product in which the protein material is dissolved in an aqueous liquid, the liquid is foamed and is extruded into a coagulant at which time coagulation is taking place the foamed protein material is being drawn. The drawn material is subsequently dried to a product having a fibrous cohesive texture. In the foaming of the proteincontaining aqueous liquid it is preferred that it take place in an alkaline medium having a pH in the range of between 8 and 13 with the protein concentration being between 10 and 15 percent by weight of the liquid.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
68 words
A PROCESS FOR THE PREPARATION OF A PROTEIN CONTAINING FOOD PRODUCT HAVING A FIBROUS, COHESIVE TEXTURE, WHICH COMPRISES DISSOLVING AN EDIBLE PROTEIN CONTAINING MATERIAL IN AN AQUEOUS LIQUID, FOAMING SAID PROTEIN-CONTAINING LIQUID SO THAT THE FOAM CONTAINS UP TO 50% BY VOLUME OF PROTEIN CONTAINING LIQUID, EXTRUDING THE FOAMED PROTEIN-CONTAINING LIQUID INTO A NON-TOXIC COAGULANT, DRAWING SAID FOAMED PROTEIN MATERIAL AS IT COAGULATES AND DRYING THE PROTEIN MATERIAL.
Claim 2
Dependent Claim
68 words
A PROCESS FOR THE PREPARATION OF A PROTEIN CONTAINING FOOD PRODUCT HAVING A FIBROUS, COHESIVE TEXTURE, WHICH COMPRISES DISSOLVING AN EDIBLE PROTEIN CONTAINING MATERIAL IN AN AQUEOUS LIQUID, FOAMING SAID PROTEIN-CONTAINING LIQUID SO THAT THE FOAM CONTAINS UP TO 50% BY VOLUME OF PROTEIN CONTAINING LIQUID, EXTRUDING THE FOAMED PROTEIN-CONTAINING LIQUID INTO A NON-TOXIC COAGULANT, DRAWING SAID FOAMED PROTEIN MATERIAL AS IT COAGULATES AND DRYING THE PROTEIN MATERIAL.
Claim 3
Dependent Claim
21 words
The process of claim 1 wherein the drawing of the foam takes place entirely or mainly before completion of the coagulation.
Claim 4
Dependent Claim
38 words
The process of claim 1 wherein the coagulant is a liquid and the foam stream is extruded in substantially a vertical direction in a bath and is drawn by the upthrust the foam stream experiences in the coagulant.
Claim 5
Dependent Claim
26 words
The process of claim 3 wherein the degree of drawing is increased by passing the liquid coagulant along the foam in the direction of extrusion thereof.
Claim 6
Dependent Claim
40 words
The process of claim 1 wherein the ratio of the rate at which the drawn and coagulated foam is discharged from the coagulating bath to the squirting rate of the foam issuing from the extrusion opening is higher than 1.3.
Claim 7
Dependent Claim
13 words
The process of claim 5 wherein the ratio is from 1.5 to 2.0.
Claim 8
Dependent Claim
21 words
The process of claim 1 wherein the starting material used for the preparation of the protein foam is a soy protein.
Claim 9
Dependent Claim
38 words
The process of claim 1 wherein the foam is prepared by foaming up an aqueous alkaline protein solution having a pH in the range between 8 and 13 and a protein concentration between approximately 10 and 15 percent.
Claim 10
Dependent Claim
28 words
The process of claim 1 wherein the protein-containing solution is foamed up with air being introduced to an air content of approximately 50 percent by volume or higher.
Claim 11
Dependent Claim
14 words
The process of claim 1 wherein the coagulant used is a polar organic solvent.
Claim 12
Dependent Claim
10 words
The process of claim 10 wherein said solvent is propanol.
Claim 13
Dependent Claim
10 words
The process of claim 10 wherein said solvent is ethanol.
