Abstract

A method and system for forming a beverage mixture comprising protein is disclosed. The method comprises heating the beverage in a heat exchanger, transferring the beverage to a hold loop located outside of the heat exchanger, and denaturizing the protein within the hold loop for a residence time, after the beverage is heated in the heat exchanger such that the denaturizing occurs outside of the heat exchanger to prevent fouling of the heat exchanger. The system comprises a beverage forming tank, a heat exchanger for heating the beverage, and a first hold loop separate from the heat exchanger, which is configured to hold the beverage for a residence time to denaturize a protein in the beverage.

First claim

What is claimed is:

1. A method of denaturizing proteins in a liquid beverage comprising:
mixing beverage contents comprising one or more proteins, each protein having an isoelectric point, and juice to form the liquid beverage having a pH at an isoelectric point or between isoelectric points of the one or more proteins in the liquid beverage;
heating the liquid beverage in a heat exchanger;
transferring the liquid beverage to a first hold loop located outside of the heat exchanger;
denaturizing the proteins within the first hold loop for a residence time after the liquid beverage is heated in the heat exchanger such that the denaturizing occurs outside of the heat exchanger to prevent fouling of the heat exchanger; and
transferring the liquid beverage to a second hold loop and sterilizing the liquid beverage in the second hold loop.

2. The method of claim 1 wherein the first hold loop is a stainless steel pipe.

3. The method of claim 1 wherein the residence time in the first hold loop is within a range of 30 to 180 seconds.

4. The method of claim 1 wherein the liquid beverage is heated in the heat exchanger within a range of 180° F. to 210° F. prior to transferring the liquid beverage to the first hold loop.

5. The method of claim 1 wherein the liquid beverage comprises a fruit juice smoothie comprising 3% to 8% whey protein.

6. The method of claim 1 wherein the first hold loop is configured to be bypassed during processing of other liquid beverages.

7. The method of claim 1 wherein a swing panel comprising a removable pipe is configured to route the liquid beverage to the heat exchanger and to the first hold loop.

8. The method of claim 1 wherein no additional heating is applied to the liquid beverage in the first hold loop.

9. The method of claim 1 wherein the liquid beverage is passed through a third hold loop.

10. The method of claim 1 wherein the liquid beverage is passed through a homogenizer.

11. A method for denaturizing protein in a liquid beverage mixture comprising:
forming the liquid beverage mixture comprising a protein having an isoelectric point and juice, the liquid beverage mixture having a pH at the isoelectric point of the protein;
heating the liquid beverage mixture;
after heating the liquid beverage mixture transferring the liquid beverage mixture to a first hold loop;
denaturizing the protein within the first hold loop for a residence time after the liquid beverage mixture is heated; and
transferring the liquid beverage to a second hold loop and sterilizing the liquid beverage in the second hold loop.

12. The method of claim 11 wherein the first hold loop is a stainless steel pipe.

13. The method of claim 11 wherein the residence time in the first hold loop is within a range of 30 to 180 seconds.

14. The method of claim 11 wherein the liquid beverage mixture is heated within a range of 180° F. to 210° F. prior to transferring the liquid beverage mixture to the first hold loop.

15. The method of claim 11 wherein the liquid beverage mixture comprises a fruit juice smoothie comprising 3% to 8% whey protein.

16. The method of claim 11 wherein a swing panel comprising a removable pipe routes the liquid beverage mixture to the first hold loop.

17. The method of claim 11 wherein no additional heating is applied to the liquid beverage mixture in the first hold loop.

18. The method of claim 11 wherein the liquid beverage mixture is passed through a third hold loop.

19. The method of claim 11 wherein the liquid beverage mixture is passed through a homogenizer.

20. The method of claim 11 wherein the protein is formed from one of dairy, plants, and combinations thereof.

21. The method of claim 11 further comprising forming the liquid beverage mixture with more than one protein.
