PROBLEM TO BE SOLVED: To provide a method for producing alpharized rice, free from the need of setting a soaking process, and retaining a rice grain shape.SOLUTION: The method for producing the alpharized rice includes sequentially a pressure steaming process S1 of steaming rice grains as the raw material by pressure steam, a boiling process S3 of alpharizing the rice grains after the pressure steaming process, a high-temperature drying process S4A of drying the rice grains at high temperature after the alpharizing process, and a low-temperature drying process S4B of drying at low temperature lower than that of the high-temperature drying process. Thus an alpharized layer is formed on a rice grain surface by pressure steaming before the boiling process without setting a soaking process.COPYRIGHT: (C)2012,JPO&INPIT【課題】浸漬工程を設ける必要がなく、米粒の形状を維持したα化米の製造方法を提供する。【解決手段】原料である米粒を加圧蒸気で蒸煮する加圧蒸煮工程S1と、該加圧蒸煮工程後の米粒をα化する炊飯工程S3と、該α化工程後の米粒を高温で乾燥する高温乾燥工程S4Aと、該高温乾燥工程よりも低温で乾燥する低温乾燥工程S4Bとを順次設け、浸漬工程を設けず、炊飯工程前に加圧蒸煮によって米粒表面にα化層を形成させるという技術的手段を講じた。【選択図】図1
