A process for demineralizing and decolorizing fruit juice and must is disclosed. Here fruit juice and must is chromatographed on strongly acid cation exchangers in the salt form.

Process for decolorizing and demineralizing fruit juice and must

A process for the preparation of a bifunctional anion exchange resin by partial quaternization of a weakly basic anion exchanger containing tertiary amino groups which process comprises (a) partially loading the weakly basic anion exchanger with a strong acid and (b) quaternizing the partially loaded anion exchanger by means of a customary alkylating agent.

An apparatus for the countercurrent treatment of liquids with adsorbents in an adsorption-filter the space of which is divided by trays which are permeable to liquids into at least 2 chambers, in which before and/or during the charging of the adsorbent in the upward flow, the regeneration of the charged adsorbent in the downward flow and the backwasting in the upward flow particular levels to which the industrial chambers are filled are established by transferring adsorbent from one chamber to the adjacent chamber.
