Oat flakes are very versatile and being used as an ingredient for muesli, pastries and cookies, to name a few. Oats are very rich in nutritional fibre and protein. It also contains much thiamine (vitamin B1). The latter is especially important for good functioning of the muscles and its nerve system. Oats contain also all kinds of minerals, among which mangaan, magnesium and phosphorus. In order to make the flakes, the moisture content of the grain is raised by means of steam. The grains are then flattened by flattening machines, where they come out as flat flakes. It is almost impossible to flatten the grains without steam, because this extra moisture makes sure that the grains are flattened instead of crumbled.
