Abstract

The presence of a sufficient amount of a calcium complexing agent prevents the gelling of corn steep liquor.

Claims

1. A non-gelling corn steep liquor composition which comprises:

(a) corn steep liquor; and

(b) an amount of a calcium complexing agent sufficient to prevent gelling of the corn steep liquor.

2. The composition of claim 1 wherein the calcium complexing agent is an anion selected from the group consisting of phytate anions, citrate anions, oxalate anions, phosphate anions, metaphosphate anions, polyphosphate anions, phosphite anions, and anions derived from EDTA, EGTA, or NTA.

3. The composition of claim 2 wherein the calcium complexing agent is present in an amount of about 1 to 15 weight percent based on the weight of the corn steep liquor.

4. The composition of claim 3 wherein the source of the calcium complexing agent is a conjugate acid of the anion or a salt of the conjugate acid.

5. The composition of claim 4 wherein the source of the calcium complexing agent is an acid or salt selected from the group consisting of phytic acid, sodium phytate, citric acid, sodium monobasic citrate, oxalic acid, sodium oxalate, phosphoric acid, potassium monohydrogen phosphate, sodium metaphosphate, sodium dihydrogen phosphate, ammonium dihydrogen phosphate, EDTA, EDTA disodium salt, EGTA, EGTA disodium salt, EGTA dipotassium salt and nitrilotriacetic acid potassium salt.

6. The composition of claim 5 wherein the pH of the composition is about 3.8 to 4.5

7. The composition of claim 6 wherein the calcium complexing agent is present in an amount of about 3 to 12 weight percent based on the weight of the corn steep liquor.

8. The composition of claim 7 wherein the calcium complexing agent is a phosphate anion.

9. The composition of claim 8 wherein the source of the phosphate anion is phosphoric acid.

10. The composition of claim 8 wherein the source of the phosphate ion is an ammonium or alkali metal mono-, di-, or tribasic phosphate salt.
