Abstract

A method for eliminating the uncooked curd defect in process cheese products associated with fortification of milk during the natural cheese make process. This fortification results in a significant increase in the amount of calcium bound in the casein micelle. The fortified milk is subjected to an acid or acid producing material that quickly lowers the pH either before or after pasteurization to a pH of approximately 6.6 to 5.70. The acidification is performed under turbulent conditions to maintain milk protein native integrity. The acidification step results in a significant migration of calcium out of the casein micelle and into a soluble form that is carried away with the whey stream. The acidified fortified milk is then subjected to the conventional cheese making process. The resulting natural cheese can then be further processed into a process cheese product without the risk of uncooked curd particles in the finished product.

Claims (45)

1. A method for making a process cheese product, the method comprising:

fortifying milk with additional dairy solids up to a legally acceptable level for the making of cheese;

acidifying the fortified milk to a pH of approximately 6.6 to 5.75 under turbulent conditions;

forming a cheese from the acidified fortified milk;

grinding the cheese and adding emulsifier salts thereto;

cooking the cheese to produce a molten process cheese mass; and

forming the molten process cheese mass to a useable form.

2. The method of claim 1 wherein the fortified milk is acidified after pasteurization.

3. The method of claim 1 wherein the fortified milk is acidified in-line in a region of turbulent flow.

4. The method of claim 1 wherein the fortified milk is acidified to a pH range of approximately 6.5 to 6.1.

5. The method of claim 1 wherein the fortified milk is acidified with an organic or inorganic acid or acid producing bacteria.

6. The method of claim 1 wherein the milk is fortified with at least 14% additional dairy solids.

7. A method for making a process cheese product, the method comprising:

fortifying milk with additional dairy solids up to a legally acceptable level for the making of cheese;

acidifying the fortified milk to a pH of approximately 6.6 to 5.75 under turbulent conditions;

forming a coagulum from the acidified fortified milk;

cutting the coagulum to separate curd and whey;

draining the whey from the curd;

processing the curd to form cheese;

grinding the cheese and adding emulsifier salts thereto;

cooking the cheese to produce a molten process cheese mass; and

forming the molten process cheese mass to a useable form.

8. The method of claim 7 wherein the fortified milk is acidified after pasteurization.

9. The method of claim 7 wherein the fortified milk is acidified in-line in a region of turbulent flow.

10. The method of claim 7 and further comprising pasteurizing the fortified milk and wherein the fortified milk is acidified before pasteurization.

11. The method of claim 7 wherein the fortified milk is heat-treated before or after acidification.

12. The method of claim 7 wherein the fortified milk has neither been heat-treated or pasteurized.

13. The method of claim 7 wherein the fortified milk is acidified while flowing through a conduit under turbulent conditions.

14. The method of claim 13 wherein the turbulent flow occurs at a “T” connection.

15. The method of claim 13 wherein the turbulent flow occurs at an elbow.

16. The method of claim 13 wherein the acidification occurs in a batch tank under turbulent conditions.

17. The method of claim 7 wherein the fortified milk is acidified with citric acid.

18. The method of claim 17 wherein the fortified milk is acidified with an organic or inorganic acid or acid producing bacteria.

19. The method of claim 7 wherein the temperature of the fortified milk during acidification is less than 35° F. or greater than 100° F.

20. The method of claim 7 wherein a cheese like product is produced using a combination of dairy proteins and fat with or without the formation of a coagulum.

21. The method of claim 7 wherein fortified milk is used directly into the manufacture of process cheese products thereby skipping the formation of curds and whey.

22. Tile method of claim 7 wherein the milk is fortified with at least 14% additional dairy solids.

23. A method for reducing translucent cheese particles in a process cheese made from a cheese in which the cheese milk was fortified with additional dairy solids, the method comprising:

acidifying the fortified cheese milk to a pH of approximately 6.6 to 5.75 under turbulent conditions; and

thereafter using the cheese produced with the acidified fortified milk to make the process cheese product.

24. The method of claim 23 wherein the fortified milk is acidified after pasteurization.

25. The method of claim 23 wherein the fortified milk is acidified in line in a region of turbulent flow.

26. The method of claim 23 wherein the fortified milk is acidified to a pH range of approximately 6.5 to 6.1.

27. The method of claim 23 wherein the fortified milk is acidified with an organic or an inorganic acid or acid producing bacteria.

28. The method of claim 23 wherein the milk is fortified with at least 14% additional dairy solids.
