摘要：
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.
