Abstract

Disclosed are processes for contacting a protein containing material with one or more wet-mill streams. The protein content of the protein containing material is increased.

First claim

What is claimed is:

1. A corn protein concentrate comprising:
a) corn protein, wherein the corn protein is present in the corn protein concentrate in an amount of greater than 70% corn protein on a dry basis; and
b) sugars of degree of glucose polymerization 1-13 and having glucose units attached by alpha-glycosidic linkages, wherein at least 10% of the sugars of degree of glucose polymerization 1-13 (total area 1-13) are sugars of degree of glucose polymerization 5-13 (total 5-13).

2. The corn protein concentrate according to claim 1 , wherein the corn protein concentrate does not include exogenous saccharification enzymes.

3. The corn protein concentrate according to claim 2 wherein the saccharification enzymes are derived from microorganisms.

4. The corn protein concentrate according to claim 2 , wherein the saccharification enzymes are selected from the group consisting of glucoamylases, pullulanases, and mixtures thereof.

5. The corn protein concentrate according to claim 3 , wherein the microorganisms are selected from the group consisting of fungi, bacteria, and mixtures thereof.

6. The corn protein concentrate according to claim 1 , wherein at least 20% of the sugars of degree of glucose polymerization 1-13 (total area 1-13) are sugars of degree of glucose polymerization 5-13 (total 5-13.

7. The corn protein concentrate according to claim 1 , wherein at least 30% of the sugars of degree of glucose polymerization 1-13 (total area 1-13) are sugars of degree of glucose polymerization 5-13 (total 5-13).

8. The corn protein concentrate according to claim 1 , wherein at least 35% of the sugars of degree of glucose polymerization 1-13 (total area 1-13) are sugars of degree of glucose polymerization 5-13 (total 5-13).

9. The corn protein concentrate according to claim 1 , wherein at least 40% of the sugars of degree of glucose polymerization 1-13 (total area 1-13) are sugars of degree of glucose polymerization 5-13 (total 5-13).

10. The corn protein concentrate according to claim 1 , wherein at least 55% of the sugars of degree of glucose polymerization 1-13 (total area 1-13) are sugars of degree of glucose polymerization 5-13 (total 5-13).

11. The corn protein concentrate according to claim 1 , wherein the corn protein concentrate comprises at least 80% corn protein on a dry basis.

12. The corn protein concentrate according to claim 1 , wherein the corn protein concentrate comprises at least 90% corn protein on a dry basis.

13. The corn protein concentrate according to claim 1 , wherein the corn protein concentrate comprises at least 70% to 90% corn protein on a dry basis.

14. The corn protein concentrate according to claim 1 , wherein the corn protein concentrate comprises at least 70% to 93% corn protein on a dry basis.

15. A corn protein concentrate comprising:
a) corn protein, wherein the corn protein is present in the corn protein concentrate in an amount of at least 75% to 80% corn protein on a dry basis; and
b) sugars of degree of glucose polymerization 1-13 and having glucose units attached by alpha-glycosidic linkages, wherein at least 10% of the sugars of degree of glucose polymerization 1-13 (total area 1-13) are sugars of degree of glucose polymerization 5-13 (total 5-13).

16. A corn protein concentrate produced by the process comprising:
a) providing a grain steeped under conditions to form a steeped grain;
b) separating starch from protein in the steeped grain to provide a protein fraction and a starch fraction;
c) adding carbohydrase enzymes to the protein fraction to degrade starch and to obtain a corn protein concentrate,

wherein the corn protein is present in the corn protein concentrate in an amount of at least 75% to 80% corn protein on a dry basis; and
b) sugars of degree of glucose polymerization 1-13 and having glucose units attached by alpha-glycosidic linkages, wherein at least 10% of the sugars of degree of glucose polymerization 1-13 (total area 1-13) are sugars of degree of glucose polymerization 5-13 (total 5-13).
