PURIFICATION OF POLYPHENOLS

The present invention relates to a A process for providing a fraction enriched in polyphenols from a starting material, the process comprises the steps of: (i) solubilizing the starting material in an aqueous solvent; (ii) adjusting pH to below pH 3 (preferably about pH 1); (iii) contacting the star...

Beschreibung
Zusammenfassung:	The present invention relates to a A process for providing a fraction enriched in polyphenols from a starting material, the process comprises the steps of: (i) solubilizing the starting material in an aqueous solvent; (ii) adjusting pH to below pH 3 (preferably about pH 1); (iii) contacting the starting material with a chromatographic resin; (iv) desorbing the polyphenols from the chromatographic resin to provide an eluate comprising the polyphenols; (v) adjusting pH of the eluate to above pH 3.5 (preferably pH 4); and (vi) separating the eluate from the eluted polyphenols to obtain the fraction enriched in polyphenols. The invention furthermore related to products comprising such polyphenols enriched fractions.
