PROBLEM TO BE SOLVED: To provide a method for producing a ginger processed product enriched with shogaols with a good productivity.SOLUTION: A method for producing a ginger processed product has a freezing step of subjecting ginger as a raw material to freezing treatment, a steam heating treatment step of subjecting ginger after freezing treatment to heating treatment in the coexistence of steam under conditions of a temperature of 100 to not more than 150°C, preferably, 110 to 130°C and a pressure of 0.12 to 0.30 MPa, preferably for a heating treatment time of 5 hours or longer. The temperature in the freezing step is -10°C or lower. A method for enriching shogaols comprises subjecting ginger subjected to freezing treatment to heating treatment in the coexistence of steam under a condition of a temperature of 100 to 150°C to convert gingerols contained in ginger into shogaols.SELECTED DRAWING: NoneCOPYRIGHT: (C)2017,JPO&INPIT【課題】生産性良くショウガオール類が富化されたショウガ加工物を製造する方法を提供する。【解決手段】原料であるショウガを冷凍処理する冷凍工程と、冷凍工程後のショウガを、水蒸気共存下、温度100~150℃以下好ましくは110~130℃及び圧力が0.12~0.30MPaの条件で好ましくは、加熱処理時間を5時以上で加熱処理する蒸気加熱工程と、を有するショウガ加工物の製造方法。冷凍工程における温度が、-10℃以下であるショウガ加工物の製造方法。冷凍処理されたショウガを、水蒸気共存下、温度100~150℃の条件で加熱処理して、ショウガに含まれるジンゲロール類をショウガオール類へ変換するショウガオール類の富化方法。【選択図】なし
