The skim milk is then fractionated using ultrafiltration to make a skim concentrate that is lactose-reduced. [1] This process separates milk components according to their molecular size. Milk then passes through a membrane that allows some of the lactose, minerals, and water to cross through.
The protein in human milk is approximately 60% whey and 40% casein. [11] The protein fraction in whey constitutes approximately 10% of the total dry solids in whey. This protein is typically a mixture of beta-lactoglobulin (~65%), alpha-lactalbumin (~25%), bovine serum albumin (~8%) (see also serum albumin ), and immunoglobulins . [ 12 ]
Lactotripeptides are two naturally occurring milk peptides: Isoleucine-Proline-Proline (IPP) and Valine-Proline-Proline (VPP). These lactotripeptides are derived from casein, which is a milk protein also found in dairy products. Although most normal dairy products contain lactotripeptides, they are inactive within the original milk proteins.
As well as being high in protein and helping to promote muscle growth, whey protein powder is very high in calcium. A 1.2-ounce scoop of whey protein powder isolate contains about 160 mg or 12% of ...
Like cow’s milk, pasteurized goat’s milk is extremely nutrient-dense but has even more protein and calcium, packing in 327 mg of calcium and 9 grams of protein per 1-cup serving — making it ...
For bodybuilders, whey protein provides amino acids used to aid in muscle recovery. [15] Whey protein is derived from the process of making cheese from milk. There are three types of whey protein: whey concentrate, whey isolate, and whey hydrolysate. Whey concentrate is 29–89% protein by weight whereas whey isolate is 90%+ protein by weight.

This makes the milk coagulate or curdle, separating the milk solids (curds) from the liquid whey. [4] Sweet whey is the byproduct of rennet-coagulated cheese, and acid whey (also called sour whey) is the byproduct of acid-coagulated cheese. [ 5 ]
