Abstract: A method for producing a granular material, comprising treating unprocessed starch(es) with acid treatment, oxidation treatment and/or enzymatic treatment to obtain partially degraded starch(es), the unprocessed starch including 5% by weight or more of amylose relative to the unprocessed starch; obtaining a raw material comprising 45% by weight or more of a starch relative to a total amount of the granular material, the starch comprising 7% by weight or more of the partially degraded starches relative to the total amount of the granular material; and granulating the raw material by heating and compressing with an extruder, wherein a water absorption rate is 250-700% by weight, a compressive syneresis rate is 7% by weight or more, and a content of particles over a sieve of 0.5 mm aperture in the granular material is 40-100% by weight.

Abstract: 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.
