Being production method of the bean milk which produces the bean milk from the germination induction processing soybeans, it designates that it offers the production method of the bean milk whose it is possible to adjust the flavor of the bean milk which is obtained as purpose. This invention, germination induction processing process and the germination induction processing soybeans which at least germination it induces process the soybeans the , regards the production method of the bean milk which includes about the homogeneous chemical engineering which process, and excludes the empty from Kure empty partition stage or Kure which obtain Kure homogeneity processes. The germination induction processing process which germination it induces processes the soybeans, in soybean partition stage and the said dipping process which are made to put in a state where the soybeans which are soaked with dipping process and the said dipping process which make the soybeans the dipping water soak which at least includes the kalium ion or the phosphoric acid ion at specified density are separated from the aforementioned dipping water and/or after the said soybean partition stage, the vapor contact process which makes the vapor contact where oxygen is included in the soybeans and, is the germination induction processing process which is included.発芽誘導処理大豆類から豆乳を製造する豆乳の製造方法であって、得られる豆乳の風味を調整することが可能な豆乳の製造方法を提供することを目的とする。本発明は、少なくとも大豆類を発芽誘導処理する発芽誘導処理工程と、発芽誘導処理大豆類を磨砕して呉を得る磨砕工程、及び、呉からおからを除くおから分離工程又は呉を均質化処理する均質化工程を含む豆乳の製造方法に関する。大豆類を発芽誘導処理する発芽誘導処理工程は、少なくともカリウムイオン又はリン酸イオンを所定の濃度で含む浸漬水に大豆類を浸漬させる浸漬工程と、該浸漬工程で浸漬された大豆類を前記浸漬水から分離した状態にさせる大豆分離工程と、該浸漬工程中及び/又は該大豆分離工程後、大豆類に酸素が含まれる気体を接触させる気体接触工程と、を含む発芽誘導処理工程である。
