PROBLEM TO BE SOLVED: To provide a method for processing unpolished rice which is easy to eat in a short time, without damaging a functional component such as γ-aminobutyric acid contained in a rice bran layer.SOLUTION: A processing of unpolished rice includes an immersion step for immersing the unpolished rice, and a draining step for draining the unpolished rice after the immersion step. In the immersion step, such technical means is taken that an enzyme for decomposing fibers is added into immersion water, and the immersion water is maintained within a temperature range of 40°C-60°C, and immersion is performed for 30 minutes to 3 hours.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】糠層に含まれるγ-アミノ酪酸等の機能性成分を損なうことなく、短時間で食べやすい玄米を加工する方法を提供することを目的とする。【解決手段】玄米の加工において、玄米を浸漬する浸漬工程と、該浸漬工程後の玄米を水切りする水切り工程とを含み、前記浸漬工程では、繊維質を分解する酵素を浸漬水に添加するとともに、該浸漬水を40℃~60℃の温度範囲に維持し、30分~3時間浸漬とする、という技術的手段を講じるものとした。【選択図】図1
