The effects of these pentosans on the physical and technological properties of the dough and bread and bread staling were then determined. Results show that all three pentosans markedly increased the water absorption and loaf volume, and retarded bread staling. Water-soluble rye pentosans in particular showed the most desirable effects. 收起
