Description After cohesive gluten proteins are removed from wheat flour, centrifugation of the water suspension separates a tightly packed dense layer of wheat starch from a less dense mucilaginous material called starch tailings. Insoluble pentosans were isolated from starch tailings to study their effect on bread quality. Incorporation of the insoluble pentosans into bread lowered bread quality. A significant decrease in bread vol. (6%) occurred when 0.5% insoluble pentosans was added to wheat flour. Addition of 2% pentosans further decreased loaf vol. by 2%. Such adverse effects were partially overcome by addition of an optimum level of a pentosanase or an alpha-amylase and more completely overcome with addition of a combination of the enzymes. Pentosanase hydrolysed about 60% of total insoluble pentosans in solution in 0.5 h. The solubilized pentosans slightly increased the relative viscosity of the solution. [From En summ.]
