Wheat human food, having a protein content of about 13%, which is relatively high compared to other major cereals but relatively low in protein quality for supplying essential amino acids. When eaten as the whole grain, wheat is a source of multiple nutrients and dietary fiber. In a small part of the general population, gluten – the major part of wheat protein – can trigger coeliac disease, noncoeliac gluten sensitivity, gluten ataxia, and dermatitis herpetiformis. Cultivation and repeated harvesting and sowing of the grains of wild grasses led to the creation of domestic strains, as mutant forms ('sports') of wheat were
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
