How is Soy Protein Powder made?
Soy protein powder is made from soy beans, a member of the legume family. However these soy beans contain unwanted fat and carbs which need to be removed. Dried beans are milled into flour and then processed with various methods including with water, alcohol and acid. Heat and pressure are also used to help separate the unwanted fat and carbohydrates. The resulting powder if dried to provide soy protein concentrates and isolates depending on the purity of the resulting protein powder.
