PROBLEM TO BE SOLVED: To provide a production method for efficiently culturing an enzyme food with a high yield by further devising a method for dry culture of rice bran by using rice bran as a substrate and culturing with Aspergillus oryzae.SOLUTION: There is provided a method for culturing a brown-rice enzyme by using rice bran, etc., as a substrate and culturing with Aspergillus oryzae, where powder of rice bran, etc., is processed into particles, then the particles are steamed, inoculated with Aspergillus oryzae, and cultured in a culture chamber, includes: a first step of stacking the rice bran inoculated with the Aspergillus oryzae on a culture bed at a predetermined thickness a second step of rising the temperature of the stacked rice bran to start fermentation a third step of keeping the temperature of the stacked rice bran to a suitable level for the purpose of continuing the fermentation action a fourth step of providing binding force between each rice bran by the adhesive force due to the fermentation action of the Aspergillus oryzae a fifth step of dividing the rice bran in clumps and a sixth step of fermenting the clumps of the rice bran so that the rice bran is wrapped by the Aspergillus oryzae in a color of substantially white.COPYRIGHT: (C)2013,JPO&INPIT【課題】米糠を基質とし、麹菌によって培養する米糠の乾式培養養をさらに工夫を凝らし、効率よく、歩留まりよく行うための製造方法を提供する。【解決手段】米糠等の基質に麹菌を培養し、玄米酵素を培養する方法であって、米糠等の粉末を粒子状に加工し、蒸し、麹菌を接種し、培養室で培養する培養法に於いて、培養床に、所定の厚さに該麹菌を接種した米糠を積層する第1の工程、該積層した米糠の品温を高め、発酵開始させる第2の工程と、該発酵作用を継続するために適度な品温を維持する第3の工程と、該米糠が、該麹菌の発酵作用による粘着力によって、米糠相互の結合力を持つ第4の工程と、該米糠を塊状に分ける第5の工程と該塊状になった米糠を麹菌によって略白く包むように発酵させる第6の工程によって培養した米糠等の培養方法。【選択図】なし
