Whey is the liquid remaining after milk has been curdled and strained. It is a byproduct of the manufacturing of cheese or casein and has several commercial uses. Whey proteins consist of α-lactalbumin, β-lactoglobulin, serum albumin, immunoglobulins, and proteose peptones. Whey protein is the collection of globular proteins isolated from whey. To produce cheese, rennet or an edible acid is added to heated milk.
Whey is left over when milk is coagulated during the process of cheese production and contains everything that is soluble from milk after the pH is dropped to 4. Whey can be denatured by heat. Whey is used to produce whey cheeses such as ricotta, brunost, and whey butter and many other products for human consumption. 1,000 pounds of whey are required to make a few pounds of whey butter.
