Soy protein isolate
To make soy protein isolate, the soybeans are put into a tub of hexane, a petroleum solvent similar to gasoline.
Hexane is used because it is a cheap way to separate the oil from protein in soybeans.
Soy protein isolate is found in non-organic soy oil and soy protein ingredients. For example, it is found in non-organic veggie burgers, meat alternatives, protein powder, and nutrition bars.
It is NOT in organic foods.
Chemical hexane has been classified as a neurotoxin by the Centers for Disease Control and Prevention
