METHOD FOR REDUCING THE SACCHARIDE CONTENT OF JUICE CONCENTRATES

1 . A method for reducing the saccharide content in juice concentrates having an initial saccharide concentration of more than 20% (w/v), comprising the steps:

a) contacting the juice concentrate with at least one microorganism,

b) fermenting the juice concentrate,

c) contacting the juice concentrate with a gaseous composition,

d) contacting the gaseous composition with an adsorber, wherein the adsorber comprises a zeolite,

wherein steps c) and d) are carried out simultaneously at least for a time.

2 . The method as claimed in claim 1 , wherein steps b), c) and d) are carried out simultaneously at least for a time.

3 . The method as claimed in claim 1 , wherein the juice concentrate has a saccharide concentration of more than 20 and up to 75% (w/v).

4 . The method as claimed in claim 1 , wherein the juice concentrate has a saccharide concentration of from 30 to 55% (w/v).

5 . The method as claimed in claim 1 , wherein, after step d) has been carried out, the gaseous composition is repeatedly contacted in the form of step c) with the juice concentrate.

6 . The method as claimed claim 1 , wherein the at least one microorganism is selected from the group consisting of yeasts and bacteria and mixtures thereof.

7 . The method as claimed in claim 1 , wherein the zeolite is selected from the group consisting of MFI zeolites, silicalites and beta zeolites and mixtures thereof.

8 . The method as claimed in claim 1 , wherein the fermentation of the juice concentrate according to step b) is carried out under anaerobic or microanaerobic conditions.

9 . The method as claimed in claim 1 , wherein the adsorber additionally comprises at least one binder selected from the group consisting of silica, silicates, bentonite, PTFE and mixtures thereof.

10 . A use of the method as described in claim 1 , for producing a juice concentrate with a reduced saccharide content.
