Water insoluble cellulosic fraction-based fibers were prepared from low-valued agricultural processing by-products, agricultural residues and energy crops by removing the alkali-extractable hemicelluloses and processing the alkali insoluble material under high temperature and high shear conditions. Most of them contained more than 90% water insoluble dietary fiber. Sugar composition and glycosyl-linkage analysis show that they are composed of cellulose and arabinoxylans indicating that they have a typical cellulosic arabinoxylan structure. They have very high water holding capacity varying from 6.4 to 74.3 g/g (water/fiber), high viscosity, and they all show shear thinning flow behavior. Owing to their high functionality and non-caloric nature, they are very interesting and commercially valuable class of health-promoting, insoluble dietary fiber based bulking agents, viscosifiers and texturizing agents for use in food and non-food applications.
