Gluten is a protein found in wheat. Nearly 1% of Americans are allergic to gluten. Products labeled as GFCO certified gluten free contain less than 10 ppm gluten.
Gluten is a protein found in wheat, barley, rye and other grains. Gluten is called a storage protein because it is found in the seed of the plant and stores nutrients. Since gluten can removed from wheat easily, it is widely used as a source of protein or thickening agent in prepared foods.
