PROBLEM TO BE SOLVED: To solve the problem that, though attention is paid on hydrogen atoms as molecules bringing out health promotion including an anti-inflammatory action, even if high concentration hydrogen water is ingested, whether an effective amount of the molecule atoms can reach the small intestine and further the large intestine is doubtful, then, to provide a method for utilizing a health promotion action where they are administrated not directly to the human being or animals but to a probiotic forming intestinal flora before the intake, and the functions of bacterial strains are activated before the intake, and better intestinal flora formation is expected.SOLUTION: Provided is a method where, before a probiotic is ingested or before a probiotic is added to a food of a fermented food raw material, hydrogen water is added to the probiotic or the raw material, and hydrogen molecules are acted to act the hydrogen molecules on the probiotic.SELECTED DRAWING: NoneCOPYRIGHT: (C)2018,JPO&INPIT【課題】水素分子は、抗炎症作用をはじめとした生体作用によって健康増進をもたらす分子として注目されているが、高濃度水素水を摂取しても、小腸さらには大腸まで有効量の水素分子が到達できるかどうか疑わしい。そこで、直接ヒトや動物ではなく、腸内フローラを形成するプロバイオティクスに摂取前に投与し、摂取前に菌株の機能を活性化して、よりよい腸内フローラ形成を期する健康増進作用の利用方法を提供する。【解決手段】プロバイオティクスを摂取する前に、あるいはプロバイオティクスを発酵食品原料の食品に加える前に、プロバイオティクスあるいは原料に水素水を加え、水素分子を作用させ、プロバイオティクスに水素分子を作用させる方法。【選択図】なし
