PROBLEM TO BE SOLVED: To provide a production method of heat-treated grain flour capable of producing a grain flour-containing food product excellent in secondary workability, and having excellent texture.SOLUTION: In a production method of heat-treated grain flour, raw material grain flour is subjected indirectly to dry heat treatment to raise a product temperature of the raw material grain flour, and then to wet heat treatment. Preferably, dry heat treatment is performed for 0.1-60 seconds, and the product temperature of the raw material grain flour is raised up to a prescribed temperature of 60°C or lower. Further preferably, in the wet heat treatment, the product temperature of 80-120°C of the raw material grain flour is maintained for 1-60 seconds.SELECTED DRAWING: NoneCOPYRIGHT: (C)2018,JPO&INPIT【課題】二次加工性に優れ、食感の良好な穀粉含有食品を製造し得る熱処理穀粉の製造方法を提供すること。【解決手段】本発明の熱処理穀粉の製造方法は、原料穀粉に対し、間接的に乾熱処理して該原料穀粉の品温を高めた後で湿熱処理する。前記乾熱処理を0.1~60秒間行い、前記原料穀粉の品温を60℃以下の所定温度まで高めることが好ましい。前記湿熱処理では、前記原料穀粉の品温80~120℃を1~60秒間維持することが好ましい。【選択図】なし
