Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
77 words
A process for producing a heat coagulable viscous protein product substantially free of added salts which comprises: a. forming an aqueous slurry of an oleaginous seed material present at a solids concentration of less than about 15 percent (weight/volume basis) based upon the total volume, said slurry having a pH of about 5.1 to about 5.9; b. separating the liquid from the solids portion of said slurry; and c. recovering said protein product from said separated liquid.
Claim 2
Dependent Claim
77 words
A process for producing a heat coagulable viscous protein product substantially free of added salts which comprises: a. forming an aqueous slurry of an oleaginous seed material present at a solids concentration of less than about 15 percent (weight/volume basis) based upon the total volume, said slurry having a pH of about 5.1 to about 5.9; b. separating the liquid from the solids portion of said slurry; and c. recovering said protein product from said separated liquid.
Claim 3
Dependent Claim
13 words
A process according to claim 1, wherein the oleaginous seed material is leguminous.
Claim 4
Dependent Claim
16 words
A process according to claim 1, wherein the oleaginous seed material is a defatted leguminous material.
Claim 5
Dependent Claim
25 words
A process according to claim 3, wherein the defatted leguminous material is soybean and the temperature of the aqueous slurry is less than 60° C.
Claim 6
Dependent Claim
32 words
A process according to claim 1, wherein the aqueous slurry has a pH of about 5.5 and the aqueous slurry is maintained at a temperature between about 30° C. and 50° C.
Claim 7
Dependent Claim
33 words
A process according to claim 1, wherein an antioxidant is added to the aqueous slurry at a concentration less than about 1 weight percent based upon the weight of the oleaginous seed material.
Claim 8
Dependent Claim
17 words
A process according to claim 1, wherein the aqueous slurry of an oleaginous seed material is agitated.
Claim 9
Dependent Claim
55 words
A process according to claim 1, wherein the oleaginous seed material is defatted soybean material present at a solids concentration of between about 8 and about 12 percent (weight/volume basis) based upon the total volume, and the aqueous slurry has a pH of about 5.5, and is maintained at a temperature of about 40° C.
Claim 10
Dependent Claim
22 words
A process according to claim 1, wherein the heat coagulable viscous protein product is recovered from said separated liquid by isoelectric precipitation.
Claim 11
Dependent Claim
27 words
A process according to claim 9, wherein isoelectric precipitation is accomplished by adjusting the pH of said separated liquid to a pH between about 3.0 and 5.0.
Claim 12
Dependent Claim
15 words
A process according to claim 10, wherein the pH is between about 4.4 and 4.8.
Claim 13
Dependent Claim
21 words
