Soybean Protein Isolate

Soybean protein isolate is a highly purified form of soy protein, with most of the fat and carbohydrates removed. It is made from soybeans through a process that isolates the protein content. This results in a powder that is about 90% protein.

Manufacturers add soybean protein isolate to foods to boost protein content and improve texture. It is often used in vegetarian and vegan meat alternatives, protein bars, and some dairy-free products. Its neutral flavor and ability to bind water make it a versatile ingredient.

Soybean protein isolate is generally recognized as safe (GRAS) by the FDA for use in food. It is a common ingredient in many foods and is considered safe when consumed as part of a balanced diet. JECFA has evaluated soy protein and found it to be safe. While some people have concerns about soy consumption, scientific reviews generally indicate that moderate intake is safe for most people.
