Abstract: Disclosed are rice grains in which various water-soluble polymeric substances can be retained without applying pressure to the rice grains. Mutant rice grains (wx/ae rice grains) which are deficient in both an amylopectin branching enzyme (BEIIb) and amylose synthase I (GBSSI) are immersed in an aqueous solution of a water-soluble polymeric substance such as indigestible dextrin, arabinogalactan and polyphenol at ambient pressure and room temperature, and subsequently the mutant rice grains are dried at a temperature of 60°C or lower, preferably about 50°C, thereby producing rice grains which are impregnated with the polymeric substance or retain the polymeric substance.
