SOLUTION: Plum vinegar is concentrated at 30-90°C under reduced pressure with a vacuum concentrator 1 provided with a rotary coil heating apparatus, the precipitate is separated and recovered as plum salt by a solid-liquid separator 2, the concentrated plum vinegar filtrate is further subjected to electrodialytic desalting with an electrodialyzer 3 to obtain concentrated and desalted plum vinegar. The pH of the plum vinegar is raised beforehand to 2.5-3.0 to suppress the change in the taste and flavor of the concentrated plum vinegar and prevent the corrosion of the equipment.
