Abstract
Abstract A process for preparing products from legumes which comprises preparing an aqueous suspension containing finely ground seed from peas or beans, at a pH within the range of about 2.0 to 10.0, subjecting the suspension to one or more centrifugation operations and isolating therefrom at least one product containing essentially the protein content of the seed and another product containing essentially the starch content of the seed. A good quality fibrous by-product may also be isolated. The products are useful in the food industry.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
61 words
A process for the removal of fibrous material fro mlegume seed which comprises slurrying finely ground or powdered dehulled legume seed in an aqueous acidic medium to provide an aqueous slu7rry thereof wherein the pH is within the range of from about 2.2 to about 3.2 subjecting said aqueous slurry to screening or filtering to remove relatively large sized fibrous material.
Claim 2
Dependent Claim
61 words
A process for the removal of fibrous material fro mlegume seed which comprises slurrying finely ground or powdered dehulled legume seed in an aqueous acidic medium to provide an aqueous slu7rry thereof wherein the pH is within the range of from about 2.2 to about 3.2 subjecting said aqueous slurry to screening or filtering to remove relatively large sized fibrous material.
Claim 3
Dependent Claim
19 words
The process of claim 1 wherein the pH of the aqueous slurry is from about 2.5 to about 3.0.
Claim 4
Dependent Claim
15 words
The process of claim 1 wherein the pH of the aqueous slurry is about 2.5.
Claim 5
Dependent Claim
23 words
The process of claim 1 wherein the aqueous slurry is formed by the wet grinding of legume seed in an aqueous acid medium.
Claim 6
Dependent Claim
33 words
The process of claim 1 wherein the aqueous slurry is formed by the wet grinding of legume seed in an aqueous acid medium at a pH of from about 2.5 to about 3.0.
Claim 7
Dependent Claim
28 words
The process of claim 1 wherein the aqueous slurry is formed by the wet grinding of legume seed in an aqueous medium at a pH of about 2.5.
Claim 8
Dependent Claim
24 words
The process of claim 1 wherein the aqueous slurry contains hydrochloric acid or phosphoric acid to provide the desired pH in said aqueous slurry.
Claim 9
Dependent Claim
22 words
The process of claim 1 wherein the finely ground or powdered seed has a particle size not greater than about 120 microns.
Claim 10
Dependent Claim
31 words
The process of claim 1 wherein the temperature of the aqueous medium in which the seed is slurried is within the range of from about 15° C. to about 25° C.
Claim 11
Dependent Claim
26 words
The process of claim 1 wherein the ratio of water in said aqueous medium to the seed is from about 3:1 toa bout 10:1 by weight.
Claim 12
Dependent Claim
48 words
The process of claim 1 wherein the pH of the aqueous slurry is in the range of from about 2.5 to 3.0 and is at a temperature of from about 15° C. to about 25° C. and the ratio of the aqueous medium to seed being about 4:1.
Claim 13
Dependent Claim
60 words
The process of claim 1 wherein the aqueous slurry is formed by the wet grinding of the seed in an aqueous medium at a pH of from about 2.5 to about 3.0, at a temperature of from about 15° C. to about 25° C. and the ratio of said aqueous medium to seed is from about 3:1 to about 10:1.
Claim 14
Dependent Claim
41 words
The process of claim 1 wherein the fibrous matter thus obtained is reslurried in an aqueous acidic medium at a pH of from about 2.5 to about 3.0 and the aqueous slurry thus obtained is filtered to provide purified fibrous matter.
Claim 15
Dependent Claim
15 words
The process of claim 1 wherein said legume seed is a yellow field pea seed.
