Abstract
Abstract A process for preparing an oriented fibrous protein product which comprises holding a flowable mixture of protein-containing materials in an injection machine and then injecting said flowable mixture through a nozzle at ram pressures between 500 and 3000 kg/cm 2 into an environment at substantially atmospheric pressure or into a mold.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
54 words
A process for preparing an oriented fibrous protein product which comprises: holding a flowable mixture consisting essentially of protein containing materials in an injection machine and then injecting said flowable mixture through a nozzle at ram pressures between 1000 and 2000 kg/cm 2 into an environment at substantially atmospheric pressure or into a mold.
Claim 2
Dependent Claim
54 words
A process for preparing an oriented fibrous protein product which comprises: holding a flowable mixture consisting essentially of protein containing materials in an injection machine and then injecting said flowable mixture through a nozzle at ram pressures between 1000 and 2000 kg/cm 2 into an environment at substantially atmospheric pressure or into a mold.
Claim 3
Dependent Claim
48 words
The process of claim 1, wherein said protein-containing materials contain above 30% by weight protein on a dry basis, the moisture content of said mixture is from 20 to 80% by weight and the temperature of said injection machine and said mold when present, are below 300° C.
Claim 4
Dependent Claim
31 words
The process of claim 2 wherein said moisture content is from 25 to 65% by weight, and the temperature of said machine and, when present, said mold is below 250° C.
Claim 5
Dependent Claim
21 words
The process of claim 1 wherein at least one of said machine and said mold has a temperature above 80° C.
Claim 6
Dependent Claim
56 words
A process for producing an oriented fibrous protein product which comprises: forming a flowable protein-containing mixture; denaturing said flowable protein-containing mixture prior to or subsequent to injecting said flowable protein-containing mixture through a nozzle at rates of from 5 to 1500 g/sec. and at ram pressures between 1000 and 2000 kg/cm 2 into a pressurized mold.
Claim 7
Dependent Claim
56 words
A process for producing an oriented fibrous protein product which comprises: forming a flowable protein-containing mixture; denaturing said flowable protein-containing mixture prior to or subsequent to injecting said flowable protein-containing mixture through a nozzle at rates of from 5 to 1500 g/sec. and at ram pressures between 1000 and 2000 kg/cm 2 into a pressurized mold.
Claim 8
Dependent Claim
31 words
The process of claim 5 wherein said protein-containing mixture is held in said mold for a period of not less than 5 seconds prior to removing said mixture from said mold.
Claim 9
Dependent Claim
20 words
The process of claim 5, wherein said mold is held at a pressure of at least 20 kg/cm 2 .
Claim 10
Dependent Claim
15 words
The process of claim 5, wherein subsequent to said injection, said mold is further pressurized.
