What is Soy Protein?

Soy protein is a complete protein that contains all the essential amino acids that the body requires to build and repair tissues. Soybeans are the primary source of soy protein, and it is extracted from them. The protein is purified and isolated to eliminate other components in the soybean.

Soy protein is available in various forms, such as soy flour, soy protein concentrate, and soy protein isolate. Soy flour is produced by grinding soybeans into a fine powder. Soy protein concentrate is created by removing some of the carbohydrates and fats from soy flour. Soy protein isolate is the purest form of soy protein and is made by removing almost all of the carbohydrates and fats from soy flour.
