Some Physiochemical Properties of Wheat Flour Hemicellulose in Solution.

A hemicellulose that did not complex with borate was isolated from wheat flour "tailing." Electrophoretically, it migrated as a single component but ultracentrifuge patterns showed some polydispersity. The ratio (MsD)/(Mn) was equal to 118,000. In agreement with other studies this polysaccharide was found to be basically an arabinoxylan with short, labile arabinose side branches. It is proposed that in solution the molecule has a random coil configuration that is somewhat rigid and extended owing to these branches.
