What it is

Isolated soy protein is a highly purified protein extracted from soybeans. It is made by removing most of the fat and carbohydrates from dehulled soybeans, leaving a protein concentrate or isolate. This process results in a product that is typically over 90% protein.

Why it's used

Manufacturers add isolated soy protein to foods for its nutritional value and functional properties, such as improving texture and binding water. It is often used in meat alternatives, baked goods, dairy-free products, and protein supplements.

Health notes

Isolated soy protein is Generally Recognized As Safe (GRAS) by the FDA for use in food. It is a source of complete protein, containing all essential amino acids. Regulatory bodies like JECFA and EFSA have evaluated soy proteins. While generally considered safe, some individuals may have soy allergies.

Allergen info

Soy is one of the 9 FDA major allergens. Isolated soy protein is derived from soybeans and is therefore a major allergen.
