The effect of pentosans (water-soluble and water-insoluble) on loaf volume and bread staling rate was investigated. The water-binding capacity of pentosans was determined using the farinograph. The water- soluble pentosans absorbed 4.4 times their weight of water and the water-insoluble pentosans 9.9 times their weight. The loaf volume was not affected by adding water-soluble pentosans, but was slightly decreased with the incorporation of water-insoluble pentosans. Pentosans decreased the bread staling rate, and the effect exerted by the water-insoluble pentosans was more pronounced than that exerted by the water-soluble pentosans. Kinetic studies indicated that pentosans simply reduce the amount of starch components available for crystallization, thus decreasing the bread staling rate.
