摘要： The object of the present invention is to provide a fermentation product excellent in flavoring quality by a method in which the fermentation time can be reduced and the long-term operation is feasible in producing the fermentation product such as alcoholic beverages in the fluidized-bed reactor. The present invention relates to a process for producing a fermentation product wherein an immobilized microorganism is arranged in a fluidized bed reactor provided with a fluidized bed part, a liquid circulating part and a gas exhaust part, and a raw-material solution is fed to the reactor to conduct fermentation, characterized in that a part of a fermented solution is drawn out from the fluidized bed part and the fermented solution is returned again to the reactor whereby a fluidized bed is formed while fermentation is conducted, and the fermentation product is put out from the reactor while new raw-material solution is fed to the reactor so that the above fermentation is repeatedly carried out.
