Abstract: 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.

Abstract: The present invention concerns a beverage preparation capsule (11) defining a closed chamber for enclosing a mass of soluble and/or extractable food material, for use in a beverage preparation machine, comprising: (i) a capsule body with side walls (12), a bottom wall (13) open with a dispensing opening (14), said capsule body walls comprising an injection-moulded oil-based or biomass-based thermoplastic material, which is not a gas-barrier material, (ii) a gas and moisture impermeable top membrane (15), pierceable by injection means (N) of the machine which are adapted to inject an extraction liquid under pressure inside said chamber, and (iii) a gas and moisture impermeable bottom membrane (16) sealed inside the capsule body near the bottom wall (13), (iv) means (18) adapted to open said chamber by relative engagement with the bottom membrane under the effect of the liquid pressure increase in the chamber during injection of said liquid, characterized in that the inside or outside surface of the capsule bod
