A granular material including equal to or larger than 45% by weight of a starch, the starch including a starch composed of one, two or more types of partially degraded starch(es) produced by treating a starch containing amylose at a content of equal to or larger than 5% by weight with any one, two or more of an acid treatment, an oxidation treatment and an enzymatic treatment, at equal to or larger than 7% by weight in the granular material, wherein a water absorption rate, in which the granular material absorbs water for 1 hour at 30 degrees C. by adding 40 g of water to 5 g of the granular material, is equal to or larger than 250% by weight and equal to or smaller than 700% by weight, wherein a compressive syneresis rate, in which a water-absorbed dough that absorbs water for 1 hour at 30 degrees C. by adding 40 g of water to 5 g of the granular material is compressed at a pressure of 141.5 g/cm2 at 30 degrees C. for 10 minutes, is equal to or higher than 7% by weight, and wherein a content of particles over a sieve of 0.5 mm aperture in the granular material is equal to or larger than 40% by weight and equal to or smaller than 100% by weight.
