PROBLEM TO BE SOLVED: To provide a method for easily and inexpensively extracting an extract containing a large amount of physiologically active health functional components such as inositol, oryzanol, and ferulic acid from rice bran. SOLUTION: A step of putting a predetermined amount of rice bran in a bag and immersing it in water in a container, boiling the water by heating the container and repeating re-boiling a plurality of times, during which ash collected on the surface is collected, After removing the rice bran bag after that, boiling of the liquid, re-boiling is repeated multiple times, a step of collecting the lye generated during that period, a step of adding a predetermined amount of water when the amount of liquid in the container decreases during these repetitions, And a method of extracting an extract containing many health functional components from rice bran, which comprises a step of sterilizing the collected extract by heating. [Selection diagram] None【課題】米糠からイノシトールやオリザノールやフェルラ酸等の生理活性の高い健康機能成分の多い抽出物を手軽に且つ安価に抽出する方法の提供。【解決手段】所定量の米糠を袋に入れて容器内の水中に浸漬し、容器を加熱することで水の沸騰、再沸騰を複数回繰り返し、その間表面に浮き出てくる灰汁を収集する工程、その後米糠袋を取り出した後も、液の沸騰、再沸騰を複数回繰り返し、その間生じる灰汁を収集する工程、これら繰り返しの間、容器内の液量が低下すると所定量の水を添加する工程、及び収集された抽出物を加熱殺菌する工程からなる、米糠から健康機能成分の多い抽出物を抽出する方法。【選択図】なし
