Flavy Ion Exchange Systems with weak anion exchange resins are used to adjust the sugar/acid ratio of fruit juices (fruit acid reduction). If cation and anion exchange resins are applied it is possible to completely deionise juices and by-products for recovering the fruit sugars. By adding a polishing step with adsorption resins, colourless fruit sugar solutions can be produced.

Clarified juice is passed through selected combinations of ion exchange resins. Charged components are retained on the respective resin by ionic forces, releasing an equally charged ion (e.g. H+, OH-) into the product. When the deionising capacity of the resins is exhausted, the juice is displaced from the columns and the resins are independently regenerated with acids, bases or salts, preparing them for the next juice process cycle.
Optional adsorptive polymer vessels can be added for improved colour and organic molecules reduction.
