PROBLEM TO BE SOLVED: To provide a manufacturing method of pregelatinized brown rice powder capable of obtaining pregelatinized brown rice powder which has a high moisture content, a high pregelatinization degree, and a high yield by requiring no germination treatment step of brown rice, and sterilizing without spoiling nutrients by heating/compressing without roasting, and a manufacturing system of the same.SOLUTION: A manufacturing method of pregelatinized brown rice powder includes: a moisture content adjustment step of soaking brown rice in water so as to infiltrate water into the inside of brown rice a puffing step of heating/compressing the brown rice adjusted in the moisture content followed by expanding so as to puff and a pulverization step of rotor-pulverizing the puffed brown rice so as to bring to pregelatinized brown rice powder.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】 玄米の発芽処理工程を不要とし、更に、焙煎を行わず加熱・加圧することによって、栄養素を損なわずに殺菌し、水分量が多く、α化度が高く、且つ歩留まりが高いα化玄米粉を得ることができるα化玄米粉及びその製造方法並びにその製造システムを提供すること。【解決手段】 本発明のα化玄米粉製造方法は、玄米を水に浸漬して玄米内部に水を浸透させる水分調節工程と、前記水分調節された玄米を加熱・加圧した後、膨張させてパフ化するパフ化工程と、前記パフ化された玄米をローター粉砕してα化玄米粉にする粉砕工程と、を備える。【選択図】図2
