Both of these are derived from milk. Whey is either concentrate or isolate. Casein is the "slow digesting" protein.
Milk
Absorption is slower than whey protein but still significantly faster than casein
Dilys Henry has written: 'The corrosion resistance of some stainless steels in a milk derived medium, acid casein whey'
Vinegar causes the milk to curdle by lowering its pH, leading to a separation of the casein protein from the liquid whey. The casein proteins coagulate and form solid curds that can be separated from the liquid, leaving behind casein-free whey.
Casein is a protein found in milk and other dairy products. It is derived from the curds that form when milk is coagulated. Casein is commonly used in the production of cheese and as a dietary supplement.
Milk proteins are Whey and Casein.
No, it's not Casein free, instead it is one of the 2 proteins in cow milk- Whey and Casein
Whey is one of the two proteins in cow's milk; the other protein is casein
Whey and casein are two types of proteins found in milk. Whey is a fast-digesting protein that is quickly absorbed by the body, making it ideal for post-workout recovery. Casein is a slow-digesting protein that provides a sustained release of amino acids, which can help with muscle recovery overnight or when going without meals for extended periods.
Two kinds: casein and whey.
Casein protein is derived from milk. Many body builders use it at night time due to the fact that it metabolizes slower than other forms of protein. It is a good type of protein to use in combination with whey and soy protein
