Abstract
Methods for concentrating phenolics in a solution and compositions related to the concentrated phenolics are provided In particular, methods and compositions are described relating to concentrated phenolics obtained from cranberry feedstock extracts combined with fumaric acid as beverage additives Additionally, methods for obtaining phenolics from feedstocks using resin absorption and elution are described.
Claims26
A method of extracting phenolics comprising:
- (i) obtaining a liquid feedstock comprising cranberry juice obtained by counter current extraction;
- (ii) contacting the feedstock with a resin that binds phenolics, and that does not substantially bind to sugar and organic acids, for a time and under conditions sufficient for phenolics in the feedstock to bind to the resin, wherein the resin has a surface area of greater than or equal to about 300 m2/g;
- (iii) contacting the resin with a wash solution, wherein the wash solution does not substantially reduce the amount of phenolics bound to the resin;
- (iv) contacting the resin with an elution solution comprising a solvent, wherein the elution solution substantially decreases the amount of phenolics bound to the resin;
- and
- (v) collecting the elution solution.

An extract comprising at least anthocyanins and proanthocyanidins (PACs) and at least one of the following:
- a ratio of anthocyanins to PACs of about 1:5;
- a PACs oligomeric profile that is substantially the same as the PACs oligomeric profile in cranberry juice or cranberries;
- a ratio of PACs to total phenolics that is substantially the same as the ratio of PACs to total phenolics in cranberry juice or cranberries;
- a ratio of PACs to anthocyanins that is not the same as the ratio of PACs to anthocyanins in cranberry juice or cranberries;
- phenolics with an average molecular weight of less than 14,000 Daltons;
- less than about 5% organic acids;
- and/or
- less than about 5% sugars.
(canceled)
A composition comprising isolated fumaric acid and isolated phenolics, wherein the isolated phenolics comprises proanthocyanidins (PACs) and wherein the ratio of fumaric acid to PACs is between about 4000:1 to about 100:1.
(canceled)
A composition comprising isolated fumaric acid and isolated phenolics, wherein the isolated phenolics comprises proanthocyanidins (PACs) and wherein the ratio of fumaric acid to PACs is between about 10:1-50:1.
