Grains and the cereals made from them comprise a large group of foodstuffs that come in many guises with a broad range of different textures. Such grains as wheat, barley, oats, rye, rice, maize, and millet put in an appearance in cuisines all over the world. Breakfast foods, bread, cakes, pasta, flour, beer, porridge, and many other items are all based on them. While their large starch content is primarily important for its contribution to their significant nutritional value, it is also the source of their different types of mouthfeel.
