WHEAT BRAN
Introduction
Bran is the outer layers of the wheat. Wheat bran is a by-product of wheat flour milling.
Wheat bran is a by-product of wheat milling industry. Milling of one million tons of wheat can yield 0.25 million tons of wheat bran. For example, in Finland, one of the biggest industrial mills: Fazer Mills and Mixes Ltd., produces around 20 000 tons of wheat bran every year. More than 95 % of it is used as animal feed. The price of the wheat bran is from 70 to 140 Euros per kilo, depending on its quality.
Wheat bran usually accounts for 14-19 % of the grains weight. It consists of outer layers. Germ can also be included in bran depending on the milling process. The composition of wheat bran depends greatly on wheat variety, cultivation conditions and separation methods. Separation methods determine how much starch is attached to the aleurone layer after the separation.
