PROBLEM TO BE SOLVED: To provide a method for producing dry powder foodstuffs, capable of preventing discoloration of fruits or vegetables and breakage of active ingredients, and dry powder foodstuffs obtained by the same.SOLUTION: A method for producing dry powder foodstuffs includes a first heating step (step S104) of irradiating far-infrared radiation to a solid matter made by squeezing fruits or vegetables followed by separating squeezed liquid, and heat-drying the product at 80°C or more, and 95°C or less, and a second heating step (step S105) of irradiating after the first heating step, far-infrared radiation to the solid matter made by squeezing fruits or vegetables followed by separating squeezed liquid, and heat-drying the product at 50°C or more and 70°C or less. It is preferable to use a lava stone dry room of a far-infrared radiation rate of 83% in the first heating step and the second heating step.COPYRIGHT: (C)2014,JPO&INPIT【課題】果実又は野菜の変色及び有効成分の破壊を防止することができる乾燥粉末食品の製造方法及びそれにより得られる乾燥粉末食品を提供する。【解決手段】果実又は野菜を搾って搾り汁を分離した固形物に遠赤外線を照射し、80℃以上95℃以下の温度で加熱乾燥する第1加熱工程(ステップS104)と、第1加熱工程の後、果実又は野菜を搾って搾り汁を分離した固形物に遠赤外線を照射し、50℃以上70℃以下の温度で加熱乾燥する第2加熱工程(ステップS105)とを含む。第1加熱工程及び第2加熱工程では、遠赤外線放射率83%の溶岩石乾燥室を用いることが好ましい。【選択図】図1
