What it is
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 processed to remove the hull and then defatted. The remaining soybean meal is processed to isolate the protein content.
Why it's used
Soy protein isolate is often used as a source of protein in foods, especially in vegetarian and vegan products. It can also act as an emulsifier, helping to blend ingredients like oil and water. It is commonly found in processed meats, protein bars, and dairy alternatives.
Health notes
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 studies suggest soy protein may have benefits for heart health, but research is ongoing and evidence is mixed. JECFA has evaluated soy protein isolate and established an acceptable daily intake.
Allergen info
Soy is one of the nine major allergens designated by the FDA. Soy lecithin, often included with soy protein isolate, is also derived from soy.
