What it is

Organic soy protein isolate is a highly purified form of soy protein, with most of the fat and carbohydrates removed. It is made from soybeans, which are a legume. The protein is extracted and concentrated through a process that typically involves water or alcohol washing and drying.

Why it's used

Manufacturers use soy protein isolate to boost the protein content of foods. It is also used for its emulsifying and binding properties, helping to hold ingredients together. You can find it in a variety of products, including protein bars, shakes, meat alternatives, and baked goods.

Health notes

Organic soy protein isolate is generally recognized as safe (GRAS) by the FDA for use in food. It is a complete protein, containing all essential amino acids. Some research suggests soy protein may have benefits for heart health, but evidence is mixed. Regulatory bodies like JECFA and EFSA have evaluated soy proteins. Soy is one of the major allergens recognized by the FDA.

Allergen info

Soy is one of the nine major allergens identified by the FDA. People with a soy allergy should avoid products containing soy protein isolate.
