Whey Protein

Pack : 500 gm powder

Whey protein is a mixture of proteins isolated from whey. Whey is the liquid part of milk that separates during cheese production.

Milk actually contains two main types of protein casein (80%) and whey (20%).

Whey is found in the watery portion of milk. When cheese is produced, the fatty parts of the milk coagulate and the whey is separated from it as a by-product


There are three primary types of whey protein : whey protein concentrate (WPC), whey protein isolate (WPI), and whey protein hydrolysate (WPH). Let's look at each of these in turn:

  • Whey protein concentrate - WPC contains low levels of fat and low levels of carbohydrates (lactose). The percentage of protein in WPC depends on how concentrated it is. Lower end concentrates tend to have 30% protein and higher end up to 90%
  • Whey protein isolate - WPIs are further processed to remove all the fat and lactose. WPI is usually at least 90% protein
  • Whey protein hydrolysate - WPH is considered to be the "predigested" form of whey protein as it has already undergone partial hydrolysis - a process necessary for the body to absorb protein. WPH doesn't require as much digestion as the other two forms of whey protein. In addition, it is commonly used in medical protein supplements and infant formulas because of it's improved digestibility and reduced allergen potential.
