Casein
What is Casein?
Casein is a protein found in milk and dairy products. It is the main protein component of cow's milk and is responsible for its white, opaque appearance. Casein is typically extracted through a process of precipitating it from milk using heat or acid.
Casein is used in a variety of food products because it provides a rich source of amino acids and is helpful in achieving a desired texture or consistency, especially in cheese-making and processed foods. Evidence on health effects suggests casein is a valuable protein source, although some individuals may experience intolerance or allergic reactions.
When you see casein on a label, it's important to recognize it as a dairy-derived ingredient, which means it's not suitable for those avoiding dairy for dietary reasons.
Commonly found in: Cheese, Baby Formula, Protein Supplements, Cereal Bars
