Summary for Patent: 9,095,145
Title:Method and system for the direct injection of asparaginase into a food process
Abstract: A method and system for the direct injection of a concentrated additive is disclosed. In one aspect, the concentrated additive comprises asparaginase. Because dilution of asparaginase in chlorinated drinking water can reduce the activity of the enzyme thereby making the enzyme less effective the direct injection of the enzyme into a dough can increase the acrylamide reduction in food products.
Inventor(s): Anderson; Keith Steve (Lewisville, TX), Boudreaux; Eric Richard (Dallas, TX), Emerson; David Brian (Coppell, TX), Frazier; Phillip Stuart (Frisco, TX), Sims Pratt; Glenn (Frisco, TX)
Assignee: Frito-Lay North America, Inc. (Plano, TX)
Application Number:12/205,330
Patent Claims:1. A method for the direct injection of a liquid additive into a dough-based product, said method comprising the steps of: a) providing a concentrated liquid additive, wherein said concentrated liquid additive comprises a liquid matrix having no chlorinated water and further wherein said concentrated liquid additive comprises asparaginase; b) adding said concentrated liquid additive directly to dough ingredients; and c) mixing said concentrated liquid additive into said dough ingredients to form an asparagine deficient dough, wherein if any additional water is necessary to form the dough, the additional water is added to the dough ingredients via a different stream than the concentrated liquid additive, and further wherein said mixing comprises a grinding step.

2. The method of claim 1 wherein said additive comprises an acrylamide reducing agent.

3. The method of claim 2 wherein said additive consists essentially of asparaginase.

4. The method of claim 1 wherein said additive comprises a coloring agent.

5. The method of claim 1 wherein said additive comprises a flavoring agent.

6. The method of claim 1 wherein said additive comprises lysine.

7. The method of claim 1 wherein said additive comprises a divalent or trivalent cation.

8. The method of claim 1 wherein said additive comprises a vitamin.

9. The method of claim 1 wherein said dough ingredients comprise dry ingredients and said adding at step b) further comprises the addition of added water, wherein said added water and said concentrated liquid additive of step b) are added via different streams.

10. The method of claim 1 omitting the addition of added water.

11. The method of claim 1 wherein said dough ingredient at step b) comprises de-hulled washed corn, and said mixing step comprises grinding in a mill.

12. The method of claim 1 comprising a residence time of at between about 5 and about 10 minutes.

13. The method of claim 1 wherein said adding step b) is performed by injecting a said concentrated liquid additive onto said dough ingredients with a direct injection system.

14. The method of clam 1 wherein said concentrated liquid additive is added at step b) at a rate of between about 5 drops to about 2500 drops per minute.

15. The method of claim 1 further comprising the step of thermally processing said dough to make a thermally processed food product.

16. The method of claim 1 wherein said dough is processed for the production of a food product selected from the group consisting of tortilla chips, pretzels, crackers, and corn chips.

17. The method of claim 1 wherein said method is performed in a continuous operation.

18. The method of claim 17 wherein said continuous operation injects a set rate of said concentrated liquid additive of between about 20 ml and about 10000 ml per hour of a concentrated asparaginase having an activity of between about 1000 units per gram and about 4000 units per gram.
