Abstract
A rice improver containing a gelatinized product of an acid-treated waxy type starch or a gelatinized product of an oxidation-treated waxy type starch, wherein a cold water solubility of the rice improver in pure water at 25 degrees centigrade is equal to or higher than 50%, wherein a content of a fraction of a granular material sieved over 0.5 mm-opening (32 mesh) sieve in the rice improver is smaller than 5% by weight, and wherein a total of contents of said acid-treated waxy type starch and said oxidation-treated waxy type starch over the whole rice improver is equal to or larger than 50% by weight.

A process for preparing a cooked rice food, including cooking a rice after adding a rice improver at a ratio of equal to or larger than 0.5% by weight and equal to or smaller than 10% by weight over the rice for cook,
- wherein the rice improver contains a gelatinized product of an acid-treated waxy type starch or a gelatinized product of an oxidation-treated waxy type starch,
- wherein a cold water solubility of the rice improver in pure water at 25 degrees centigrade is equal to or higher than 50%,
- wherein a content of a fraction of a granular material sieved over 0.5 mm-opening (32 mesh) sieve in the rice improver is smaller than 5% by weight,
- wherein a total of contents of said acid-treated waxy type starch and said oxidation-treated waxy type starch over the whole rice improver is equal to or larger than 50% by weight, and
- wherein viscosity of an aqueous solution of the gelatinized products of said acid-treated waxy type starch and said oxidation-treated waxy type starch contained at 30% by weight measured by a Brookfield viscometer is equal to or higher than 30 cps and equal to or lower than 17,400 cps at 40 degrees centigrade and 30 rpm.
