What is whey and how is it produced?
Whey is a byproduct of cheese production, derived from milk. When milk is curdled and strained during the cheese-making process, the liquid that remains is called whey. This liquid is rich in proteins, lactose, vitamins, and minerals. The whey is then processed to separate the protein from the other components, resulting in various forms of whey protein powders commonly used in dietary supplements and food products.
The production of whey involves several steps, including pasteurization, separation, and filtration to concentrate the protein. After isolation, the whey can be further processed into different types such as whey protein concentrate, isolate, or hydrolysate, each varying in protein content and nutritional properties. This versatile ingredient is praised for its high-quality protein and is commonly found in protein shakes, bars, and various baked goods.
