Abstract
The present invention relates to a method for the removal of polyphenols and proteins simultaneously from a beverage by contacting the beverage with an ion exchanger that is capable of adsorbing both types of substances. The characteristic feature of the ion exchanger to be used is that it is a water-insoluble porous hydrophilic matrix to which ion exchanging groups are covalently bound.
Claims23
A method for stabilizing a beverage containing haze causing substances, comprising the following steps:
- a) contacting the beverage with a water-insoluble porous hydrophilic matrix to which ion exchanging groups are covalently bound, which is capable of adsorbing both haze forming proteins and polyphenolic compounds, and removing a portion, but not all, of the haze forming proteins and/or polyphenolic compounds;
- b) recovering the beverage from the matrix;
- c) regenerating the matrix;
- and
- d) reusing the matrix from step c) in step a).
A method for stabilizing a beverage containing haze causing substances, comprising the following steps:
- a) contacting a clarified beverage with a water-insoluble porous hydrophilic matrix to which ion exchanging groups are covalently bound, which is capable of adsorbing both haze forming proteins and polyphenolic compounds, and removing a portion, but not all, of the haze forming proteins and/or polyphenolic compounds;
- b) recovering the beverage from the matrix;
- c) regenerating the matrix;
- and
- d) reusing the matrix from step c) in step a).
A method for stabilizing a beverage containing haze causing substances, comprising the following steps:
