Oat cereals. Celiac disease (coeliac disease) is a permanent intolerance to certain gluten proteins in genetically predisposed people, having a prevalence of about 1% in the developed world. Gluten is present in wheat, barley, rye, oat, and all their species and hybrids and contains hundreds of proteins, with high contents of prolamins. Oat prolamins, named avenins, are similar to gliadins found in wheat, hordeins in barley, and secalins in rye, which are collectively named gluten. Avenins toxicity in celiac people depends on the oat cultivar consumed because of prolamin genes, protein amino acid sequences, and the immunoreactivities of toxic prolamins which
Wheat gluten (food) and chewiness of the final product. Very little is required, generally about 1 Tablespoon (15ml) per 2-3 cups (480-620 ml) of flour. The powdered form of wheat gluten (vital wheat gluten), is made by hydrating hard wheat flour to activate the gluten and then processing the hydrated mass to remove the starch, leaving only the gluten. The gluten is then dried and ground back into a powder. Seitan may be made from vital wheat gluten or from hard wheat flour (a.k.a. high-protein flour, high-gluten flour, or gluten flour). When seitan is made from vital wheat gluten, the powder is simply
