PROBLEM TO BE SOLVED: To modify rice through shortly removing a protein component contained in rice at low cost by contacting with rice the water on the cathode chamber side obtained by diaphragm electrolysis of a specific aqueous salt solution. SOLUTION: A rice is modified by contacting with rice the water on the cathode chamber side obtained by diaphragm electrolysis of an aqueous solution of an inorganic salt to remove a protein component, mainly glutelin, contained in rice. As the inorganic salt, a common salt is preferably used, and as the water generated by electrolysis, strongly alkaline water at >=pH 10.0 is preferably used. The protein component content of rice is higher toward the outer layer of rice, and it is eluted in high efficiency through contacting with the above water to bring the rice into a low-protein rice. The low-protein rice is used as a raw material for brewing and confectionery and also as a food material prepared for those such as kidney disease patients who are taking an alimentotherapy. |
