What it is

Sodium casein is the sodium salt of casein, the main protein found in milk. It is produced by treating casein with a sodium compound. This process makes the protein more soluble and easier to use in food products.

Why it's used

Sodium casein is often used as a source of protein and as an emulsifier, helping to blend oil and water in foods. It can also act as a stabilizer and thickener. You can find it in products like cream soups, sauces, and some baked goods.

Health notes

In the U.S., sodium casein is generally recognized as safe (GRAS) by the FDA when used for its intended purpose. Regulatory bodies like JECFA have evaluated it. It is a source of protein and calcium. For most people, consuming it in typical food amounts does not pose health concerns.

Allergen info
