CONCENTRATED AND DESALTED PLUM VINEGAR AND ITS PRODUCTION |
摘要 |
PROBLEM TO BE SOLVED: To provide a high-performance low-cost desalting process for producing concentrated and desalted plum vinegar and plum salt having high utility value as a new resource from surplus plum vinegar generated as a by-product of pickled plum and almost completely discarded hitherto as a waste, preventing the discard of the vinegar to environment, satisfying the other conditions and free from degradation problem. SOLUTION: Plum vinegar is concentrated at 30-90 deg.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. |
