PROBLEM TO BE SOLVED: To provide an improved thermally inhibited flour and a method of producing the same.SOLUTION: A thermally inhibited grain flour has at least 50% less hexanal after zero days or 4 weeks of storage than a flour thermally inhibited after milling. A method of producing improved thermally inhibited flour comprises: dehydrating the grains at a first temperature until becoming anhydrous or substantially anhydrous； heat-treating the dehydrated grains at a second temperature that is higher than the first temperature for a period of time sufficient to obtain, after milling, a thermally inhibited grain flour； milling the heat treated, dehydrated grains to obtain a thermally inhibited grain flour.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】改良された熱抑制フラワー及びその製造方法の提供。【解決手段】粉砕後に熱抑制されたフラワーよりも少なくとも５０％少ないヘキサナールをゼロ日又は４週間の貯蔵後に有する、熱抑制粒のフラワー。粒を第一の温度で無水又は実質的に無水になるまで脱水する工程、脱水された粒を、熱抑制粒のフラワーを粉砕後に得るのに十分な時間、第一の温度よりも高い第二の温度で熱処理する工程、熱処理され、脱水された粒を粉砕して、熱抑制粒のフラワーを得る工程を含む、改良された熱抑制フラワーの製造方法。【選択図】図１
