PROBLEM TO BE SOLVED: To provide a production method of tofu-residue powder capable of producing tofu-residue powder having a value as a completely new food product, not having a burnt smell, and not existing in conventional tofu-residue.SOLUTION: A production method of tofu-residue powder has a separation step SP3 for separating a tofu-residue mixture D obtained by heating pulverized soy bean A together with water B into soybean milk E and tofu-residue F, and a heating pulverization step SP4 for sending the tofu-residue F passing through the separation step SP3 toward a propeller by hot wind, and pulverizing and drying it until the particle size becomes less than 100 μm at a temperature below 100°C, to thereby obtain a powdery shape.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】焦げ臭がなく、従来のおからにはない全く新しい食品としての価値を有するおからパウダーを製造可能なおからパウダーの製造方法の提供。【解決手段】粉砕された大豆Aを水Bとともに加熱して得たおから混合物Dを豆乳EとおからFとに分離する分離工程SP3と、分離工程SP3を経たおからFを、熱風によってプロペラに向けて送り込み、100℃未満で粒径が100μm未満になるまで粉砕及び乾燥させてパウダー状にする乾燥粉砕工程SP4とを有するおからパウダーの製造方法。【選択図】図1
