Whey Protein ProductionBy now you have probably read quite a bit about Whey Protein and the benefits it has to offer. But how is Whey Protein made? How is it produced at all?

Whey protein is a by-product of the cheese making process. Like all dairy-based products Cheese is made following a specific procedure. Fresh milk gets delivered for cheese production. The fresh milk is tested and eventually approved by the Quality Assurance experts and then being pasteurized. The casein, or “curd”, and a portion of the milk-fat are separated out during the pasteurization process to make the cheese. The remaining liquid whey goes through a series of very fine, custom filters to separate out the whey protein from the lactose and the other remaining ingredients that are still in the liquid whey. Concentrated liquid whey enters an ion exchange tower to become further concentrated and to purify the actual whey protein. What is Ion exchange? Ion exchange is a very gentle process and does not degrade, or “break down”, the whey protein.

We’re almost there now. As the next step, the whey product now enters a special drying tower to remove water. The result is Whey Protein in form of a powder. The final step is to package the pure whey protein isolate powder into various size containers for use.
