What is Whey Protein Concentrate (WPC)?
Whey Protein Concentrate is one of the primary forms of whey protein. It is produced during the cheese-making process when milk is coagulated and separated into curds and liquid whey. This liquid whey contains a mixture of proteins, including whey protein, fats, lactose, and various bioactive compounds.
Whey Protein Concentrate contains around 70-80% protein by weight, with the remaining 20-30% comprising of fats and carbohydrates (primarily lactose). The protein content can vary depending on the specific WPC product, as manufacturers offer different concentration levels.
Whey Protein Isolate (WPI)?
Whey Protein Isolate is a more refined form of whey protein. It undergoes additional processing to remove most of the fats and carbohydrates, leaving a product that is predominantly protein. The protein content in Whey Protein Isolate is typically higher, often exceeding 90% protein by weight, with minimal fats and lactose content.
