Abstract
Abstract Method of making a stable aqueous maltodextrin solution containing maltodextrin, water and sorbic acid and a suitable food grade acid to adjust the pH to 2-4. The solution, preferably stored at an elevated temperature of, e.g., 100 DEG F., shows substantially no mold or yeast contamination after several months. The solution is preferably made up hot and transferred to shipping containers while hot.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
87 words
A method of preparing an aqueous maltodextrin solution which comprises: admixing maltodextrin, water, sorbic acid and an acidifying agent to provide a food grade aqueous solution of maltodextrin having a pH of 2-4 and a sorbic acid content of 0.02-0.1% by weight; maintaining the temperature of said solution at 130°-190° F. during the admixing step; transferring the solution while it remains at said temperature of 130°-190° F. to a clean shipping container; and storing said solution prior to use at a temperature of at least 70° F.
Claim 2
Independent Claim
87 words
A method of preparing an aqueous maltodextrin solution which comprises: admixing maltodextrin, water, sorbic acid and an acidifying agent to provide a food grade aqueous solution of maltodextrin having a pH of 2-4 and a sorbic acid content of 0.02-0.1% by weight; maintaining the temperature of said solution at 130°-190° F. during the admixing step; transferring the solution while it remains at said temperature of 130°-190° F. to a clean shipping container; and storing said solution prior to use at a temperature of at least 70° F.
Claim 3
Dependent Claim
17 words
A method according to claim 1 wherein the solution is stored prior to use at 100°-140° F.
Claim 4
Dependent Claim
16 words
The method according to claim 1 wherein said solution is stored for at least one month.
Claim 5
Dependent Claim
20 words
A method according to claim 1 comprising an additional step of adjusting the maltodextrin solids level by admixing additional water.
Claim 6
Dependent Claim
20 words
A method according to claim 1 wherein potassium sorbate is used to provide the sorbic acid component of the solution.
