Abstract
Abstract A method is disclosed for producing a bland textured protein product. The method includes the steps of mixing untextured protein material and water to form an untextured protein slurry which is fed into a flowing stream of hot, pressurized steam and carried to a zone of lower pressure. The slurry is partially dehydrated upon entering the zone of lower pressure and is texturized.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
16 words
The method of claim 1 wherein said water content is reduced at least about 50 percent.
Claim 2
Dependent Claim
33 words
The method of claim 1 wherein said water content is reduced at least about 70 percent and wherein the moisture content of the resultant textured protein material is at least about 5 percent.
Claim 3
Independent Claim
102 words
A method for texturizing protein material comprising: mixing water and protein material having a protein content of at least 30 percent to form a slurry, said slurry having a moisture content of about 70 to 85 percent, commingling a stream of said slurry and a stream of pressurized, superheated steam, said steam being at a temperature of at least 250*F. and a pressure of at least 25 p.s.i.g., said steam providing heat transfer to said slurry of about 100 to 1,250 BTU per pound of slurry, and releasing said commingled streams to a zone of lower pressure thereby texturizing said protein material.
Claim 4
Dependent Claim
16 words
The method of claim 4 wherein said steam pressure is between about 80 and 140 p.s.i.g.
Claim 5
Dependent Claim
15 words
The method of claim 4 wherein said protein content is at least about 50 percent.
Claim 6
Dependent Claim
13 words
The method of claim 6 wherein said steam pressure is about 140 p.s.i.g.
Claim 7
Independent Claim
127 words
A method for texturizing protein material comprising: mixing untextured protein material and water to form an untextured protein slurry, said protein material being capable of texturization and having a protein content of at least 30 percent dry weight basis, said slurry including from 70 to 85 percent total moisture by weight; feeding said slurry to a stream of steam in a confined cylinder means, said slurry and said steam being intimately commingled, said steam having a pressure of at least 25 p.s.i.g. and a temperature of at least 250*F., said steam being present in a weight ratio of between about 1 and 10 parts steam per part of slurry; removing said slurry to a zone of lower pressure thereby flashing off water and texturizing said protein material.
Claim 8
Dependent Claim
29 words
The method of claim 8 wherein said water is flashed off to reduce the moisture content at least about 5 percent based on the total weight of the slurry.
Claim 9
Dependent Claim
45 words
The method of claim 8 wherein said water is flashed off to reduce the moisture content at least about 50 percent based on the total weight of the slurry and wherein the moisture content of said textured protein material is at least about 5 percent.
