Soybean Protein

Soybean protein is a protein extracted from soybeans, a legume native to East Asia. It is typically made by removing the hull and oil from soybeans, then processing the remaining flakes to isolate the protein. It can be found in forms like soy protein isolate, concentrate, or textured vegetable protein.

Manufacturers use soybean protein as a meat alternative, a nutritional supplement, and an emulsifier. It helps bind ingredients, improve texture, and add protein content to foods. It is commonly found in vegetarian and vegan products, baked goods, and processed meats.

Soybean protein is generally recognized as safe (GRAS) by the FDA. It is a complete protein, containing all essential amino acids. Some research suggests that consuming soy protein may help lower LDL cholesterol levels, but evidence is mixed. JECFA and EFSA have evaluated soy protein and its components.
