A method of making a powdered whey protein, where the method includes heating a slurry comprising starting whey protein to a temperature of about 140° F. to about 300° F. The heating converts at least a portion of the starting whey protein to denatured whey protein. The method also includes subjecting the slurry to high shear conditions, and drying the slurry to leave the powdered whey protein. Also, a system for producing a powdered whey protein. The system includes a cooker to heat a slurry comprising starting whey protein, and a shear pump to subject the slurry to high shear conditions.

What is claimed is: 1. A method of making a powdered whey protein, the method comprising: heating a slurry comprising a starting whey protein to a temperature of about 140° F. to about 300° F., wherein the heating converts at least a portion of the starting whey protein to denatured whey

What is claimed is: 1. A method of making a powdered whey protein, the method comprising: heating a slurry comprising a starting whey protein to a temperature of about 140° F. to about 300° F., wherein the heating converts at least a portion of the starting whey protein to denatured whey protein; homogenizing the slurry; subjecting the slurry to high shear conditions; exposing the slurry to a sub-atmospheric pressure atmosphere; and drying the slurry to leave the powdered whey protein. 2. The method of claim 1, wherein the starting whey protein is a native whey protein. 3. The method of claim 1, wherein the slurry is derived from a cheesemaking process. 4. The method of claim 1, wherein the slurry is mixed while being heated. 5. The method of claim 1, wherein the slurry is heated by injecting steam directly into the slurry. 6. The method of claim 1, wherein the slurry is heated by an indirect heat source. 7. The method of claim 1, wherein the slurry is spray dried to form the powdered whey protein. 8. The method of claim 1, wherein the slurry has a whey protein content of about 7%, by weight, or more. 9. The method of claim 1, wherein the slurry has a total dry matter content of about 20%, by weight, or more. 10. The method of claim 1, wherein the slurry has a whey protein content of about 34% or more, by weight, relative to the total dry matter. 11. The method of claim 1, wherein the slurry comprises a pH adjusting agent. 12. The method of claim 11, wherein the pH adjusting agent is calcium hydroxide. 13. The method of claim 1, wherein the temperature is about 195° F. 14. The method of claim 1, wherein the denatured whey protein is an ingredient in a confectionary. 15. The method of claim 14, wherein the confectionary is caramel, protein bar, or meal replacement food. 16. A method of making protein enhanced caramel, the method comprising: heating a whey protein slurry to about 140° F. to about 300° F., and subjecting the slurry to high shear conditions, wherein the heating converts at least a portion of native whey protein to a denatured whey protein; homogenizing the slurry; subjecting the slurry to high shear conditions; exposing the slurry to a sub-atmospheric pressure atmosphere; drying the slurry to form a whey protein powder; and adding the whey protein powder to other ingredients and forming the protein enhanced caramel. 17. The method of claim 16, wherein the other ingredients are selected from the group consisting of butter, sugar, milk, sweetened condensed milk, partially hydrogenated vegetable oil, vegetable oil, non-fat dry milk, whey salt, soy lecithin, glucose syrup, sweetened condensed skim milk, sorbitol, sugar substitutes, whey powder, cream, cane sugar syrup, flavors, corn syrup, high-fructose corn syrup, milk, disodium phosphate, sodium bicarbonate, artificial flavors, vanilla, skim milk, and starch. 18. The method of claim 16, wherein the protein enhanced caramel is added to a confectionary product. 19. The method of claim 18, wherein the confectionary product is a protein bar.
