US 8,075,929 B2 · Grape extract, dietary supplement thereof, and processes therefor

Abstract

The present invention relates to a novel grape extract, and processes for making such, that is useful for, inter alia, treating pre-hypertension, Metabolic Syndrome and/or the conditions that comprise Metabolic Syndrome. The processes of the present invention produce a highly concentrated polyphenol product by maximizing extraction of monomeric and oligomeric procyanidins and minimizing extraction of polymeric procyanidins. The grape extract of the present invention comprises between about 5-15% monomers, about 5-20% dimers, about 3-10% trimers, about 2-10% tetramers, and about 2-10% pentamers by weight. The grape extract of the present invention can be formulated into dietary supplements, including capsules, tablets, powders, solutions, gels, suspensions, creams, gels, and the like. These dietary supplements in, for instance, powder or solution form, may be added to nutraceuticals, foods and/or beverages to form functional nutraceutical, food, and/or beverage products.

Dependent claims

A process for making a polyphenol extract from grapes comprising the steps of:

(1) contacting a member selected from the group consisting of whole grapes, grape seeds, grape pomace, and mixtures thereof with water at an elevated temperature to obtain a crude grape-water extract;
(2) treating the crude grape-water extract with a tannase enzyme at an elevated temperature to obtain a polyphenol grape extract;
(3) acidifying the polyphenol grape extract to a pH of about 1.5 to 2.5 to obtain an acidified polyphenol extract;
(4) cooling the acidified polyphenol extract;
and (5) filtering the cooled acidified polyphenol extract to obtain a filtered polyphenol extract.
