What is Whey Protein Powder? How is it Made?
Whey protein powder, also known as whey protein, is derived from the liquid part of milk that separates during the cheese-making process. Milk contains two main types of proteins: 80% casein and 20% whey. Whey is found in the liquid part of the milk. When cheese is produced, the fatty parts of the milk coagulate, and whey separates as a by-product.
If you’ve ever opened a yogurt container and seen a liquid on top, that's whey. Cheese manufacturers used to discard this by-product before its commercial value was discovered.
Whey alone is not a flavorful product, so it is flavored and sold in various forms.
Whey protein powders are absorbed very quickly and are typically consumed after exercise.
There are two main ways most people effectively use whey protein powder: to increase daily protein intake and as a part of their nutritional strategy.
Other Types of Protein Powders
There are three main types of protein powders: whey protein, casein protein, and plant-based protein powders. We have already discussed whey protein in detail.
Casein protein is another by-product of milk and is a slower-digesting protein. It is commonly consumed at night or as a snack.
Plant-based protein powders are typically a combination of proteins derived from peas, soy, and rice. These powders usually include a mix of various protein sources to provide all the essential amino acids needed for building new tissue.
Do You Need Protein Powder?
When we exercise, our muscles break down to release amino acids, which are then used to rebuild new tissue. To maintain a positive protein balance in the body, protein consumption is necessary. This is where protein from powders or foods comes into play. While protein powder is not essential for muscle growth and repair after exercise, protein itself is.
Protein powders become important if you are unable to eat after your workout or if you cannot meet your daily protein requirements through food alone. Protein powders provide a practical and quick solution to meet these needs.
