WHEAT
An ingredient used in many foods,
flour is a fine powder made from cereals or other starchy food
sources. It is most commonly made from wheat, but also maize (corn)
rye, barley and rice. Flour is always based on the presence of
starches which are complex carbohydrates.
Whereas wheat is widely used because
of an important property: when wheat flour is mixed with water, a
complex protein called gluten develops. The gluten is what gives
wheat dough an elastic structure that allows it to be worked in
variety of ways, allows retention of gas bubbles in an intact
structure, resulting in a sponge-like texture to the final products,
such as breads, cakes, pastries, and other packed products.
Usually the word flour alone refers to
wheat flour, which is one of the most important foods today. It is
produced by milling wheat.
Regular flour is produced from the
central part of wheat kernel. The bran layer is removed by sieving
during the milling process. The colour of the flour is creamy white
to white depending on the variety of wheat used. |
