What it is

Isolated soy protein is a highly purified protein extracted from soybeans. Soybeans are dehulled, defatted, and then processed to separate the protein from carbohydrates and other components. The resulting product is typically a powder with a high protein content.

Why it's used

Manufacturers add isolated soy protein for its nutritional value and functional properties, such as binding, emulsifying, and thickening. It is often used in processed meats like sausages and hot dogs, as well as in frozen meals and appetizers to improve texture and protein content.

Health notes

Isolated soy protein is generally recognized as safe (GRAS) by the FDA when used as intended. It is a source of complete protein, containing all essential amino acids. The WHO and FAO have evaluated soy proteins, and EFSA has also assessed related compounds. Evidence on the health effects of isolated soy protein at typical dietary intakes is generally positive, with some research suggesting benefits for heart health.

Allergen info

Soy is one of the nine major allergens identified by the FDA. Isolated soy protein is derived from soybeans and therefore contains soy.
