Ans: Yes, whey protein is derived from milk. Casein and whey are two primary proteins that are derived from Milk.- During cheese-making, milk is separated into curds and liquid whey. The whey, which constitutes about 20% of the protein in milk, is then separated from the curds. This liquid whey is further processed and undergoes filtration to remove most of the lactose, fat, and other non-protein components. The outcome is a concentrated form of whey protein, which is then dried and powdered to create supplementation commonly available in the market. Therefore, it can be said that whey protein is indeed made from milk, specifically from the liquid whey protein obtained during cheese production.
