Abstract

Food products and systems and methods for their production involve subjecting pasteurized milk to a concentration process thereby forming liquid concentrated milk, then fermenting the liquid concentrated milk to form a fermented concentrated milk product. The fermented concentrated milk product is combined with a liquid emulsifying agent, thereby forming a food product. The food product is formed without the fermented concentrated milk product and the food product reaching a temperature of 145° F.

First claim

What is claimed is:

1. A method for the production of a food product, the method comprising:
subjecting pasteurized milk to a concentration process thereby forming liquid concentrated milk;
fermenting the liquid concentrated milk thereby forming a fermented concentrated milk product containing one or more active dairy cultures;
combining the fermented concentrated milk product with a liquid emulsifying agent thereby forming a food product, wherein during the step of combining, the food product is formed at or below a temperature of 145° F. such that the one or more active dairy cultures from the fermented concentrated milk product are retained in the food product.

2. The method of claim 1 , further comprising removing moisture from the food product after combining the fermented concentrated milk product with the liquid emulsifying agent through evaporative processing thereby producing a plastic food product, wherein during the step of removing moisture, the plastic food product is formed at or below a temperature of 145° F. such that the one or more active dairy cultures in the food product are retained in the plastic food product.

3. The method of claim 2 , wherein removing moisture from the food product after combining the fermented concentrated milk product with the liquid emulsifying agent through evaporative processing thereby producing a plastic food product includes removing the moisture from the food product through evaporative processing in a wiped film evaporator to produce the plastic food product.

4. The method of claim 1 , wherein the concentration process includes at least one of ultrafiltration, microfiltration, reverse osmosis, or evaporation.

5. The method of claim 2 , wherein the concentration process includes at least one of ultrafiltration or microfiltration, and the concentration process removes at least a portion of lactose or serum proteins from the pasteurized milk using diafiltration.

6. The method of claim 1 , wherein combining the fermented concentrated milk product with a liquid emulsifying agent thereby forming a food product includes combining, in an inline mixer, the fermented concentrated milk product with the liquid emulsifying agent thereby forming the food product.

7. The method of claim 1 , wherein the liquid emulsifying agent includes at least one of liquid sodium phosphate, liquid sodium citrate, or liquid potassium phosphate.

8. The method of claim 1 , wherein combining the fermented concentrated milk product with a liquid emulsifying agent thereby forming a food product includes combining the fermented concentrated milk product with a predetermined amount of the liquid emulsifying agent to form the food product of a spreadable cheese.

9. The method of claim 1 , further comprising removing moisture from the fermented concentrated milk product through evaporative processing after fermenting the liquid concentrated milk and before combining the fermented concentrated milk product with the liquid emulsifying agent, wherein during the step of removing moisture, the fermented concentrated milk product does not reach a temperature of 145° F. such that the one or more active dairy cultures from the fermented concentrated milk product are retained in the fermented concentrated milk product after the step of removing moisture.

10. The method of claim 1 , further comprising combining the fermented concentrated milk product with chymosin.

11. A method for the production of a food product, the method comprising:
fermenting liquid concentrated milk thereby forming a fermented concentrated milk product containing one or more active dairy cultures;
combining the fermented concentrated milk product with a liquid emulsifying agent thereby forming a food product, wherein during the step of combining, the food product is formed at or below a temperature of 145° F. such that the one or more active dairy cultures from the fermented concentrated milk product are retained in the food product.

12. The method of claim 11 , further comprising removing moisture from the food product after combining the fermented concentrated milk product with the liquid emulsifying agent through evaporative processing thereby producing a plastic food product, wherein during the step of removing moisture, the plastic food product is formed at or below a temperature of 145° F. such that that the one or more active dairy cultures in the food product are retained in the plastic food product.

13. The method of claim 12 , wherein removing moisture from the food product after combining the fermented concentrated milk product with the liquid emulsifying agent through evaporative processing thereby producing a plastic food product includes removing the moisture from the food product through evaporative processing in a wiped film evaporator to produce the plastic food product.

14. The method of claim 11 , further comprising subjecting pasteurized milk to a concentration process thereby forming the liquid concentrated milk, wherein the concentration process includes at least one of ultrafiltration or microfiltration and removes at least a portion of lactose or serum proteins from the pasteurized milk using diafiltration.

15. The method of claim 11 , wherein the liquid emulsifying agent includes at least one of liquid sodium phosphate, liquid sodium citrate, or liquid potassium phosphate.

16. The method of claim 11 , further comprising hydrating one or more dairy powders to form the form the liquid concentrated milk.

17. A method for the production of a food product, the method comprising combining a dairy product containing one or more active dairy cultures with a liquid emulsifying agent thereby forming a food product, wherein during the step of combining, the food product is formed at or below a temperature of 145° F. such that the one or more active dairy cultures from the dairy products are retained in the food product, wherein the dairy product includes one of ground cheese or a fermented concentrated milk product.

18. The method of claim 17 , wherein the dairy product includes the ground cheese.

19. The method of claim 17 , wherein the dairy product includes the fermented concentrated milk product and the method further comprises forming the dairy product by:
filtrating pasteurized whole milk using at least one of ultrafiltration or microfiltration to form a liquid concentrated milk; and
fermenting the liquid concentrated milk to form the fermented concentrated milk product.

20. The method of claim 17 , wherein the dairy product includes the fermented concentrated milk product and the method further comprises forming the dairy product by:
hydrating one or more dairy powders to form the form a liquid concentrated milk;
pasteurizing the liquid concentrated milk; and

fermenting the liquid concentrated milk to form the fermented concentrated milk product.
