                                According to the U.S. Food and Drug Administration (FDA), a product must contain less than 20 parts per million (ppm) of gluten to be legally labeled as "gluten-free". The term "gluten 30%" is not a food product for human consumption, but rather a descriptor for an animal feed ingredient known as maize gluten feed.
