Abstract:
A novel grape seed extract is enriched in procyanidins, has total polyphenols of less than 70%, and has a low degree of polymerization (dp). Other fractions of the extract have minimal polyphenols, fiber, and protein, but contain more than 90% sugars. In some specific examples, the individual extracts are obtained by sequential ultrafiltration of a water extract of the grape seeds. A first ultrafiltration provides a first permeate (Fraction A) enriched in sugars which is useful as a flavorant, and a first retentate. The first retentate is reconstituted and subjected to a second ultrafiltration at a higher molecular weight cutoff to produce a second permeate (Fraction B) that is enriched in low molecular weight polyphenols, and a second retentate (Fraction C) that is enriched in seed fiber. The Fractions are individually suitable for different nutraceutical products, or can be combined with each other in any combination and/or with other nutraceutical agents to enhance vascular and cognitive health.

Claim (Index 10):
The extract of  claim 1 , made by the method of:\n (a) mixing washed grape seeds with heated water at a temperature below 100\u00b0 C.; (b) enzymatically treating and filtering the mixture of step (a) with a filter having pores in the range of 1-10 microns to substantially remove insoluble plant material in the extract and produce a clarified extract; (c) processing the clarified extract of step (b) by ultrafiltration with a membrane having a molecular weight cutoff of 1-5 kDa to produce a first permeate [Fraction A] and a first retentate, wherein the first permeate [Fraction A] is comprised of at least 80% sugars by dry weight; (d) reconstituting the first retentate of step (c) in water and processing by ultrafiltration with a membrane having a molecular weight cutoff in the range of 100-500 kDa to produce a second permeate [Fraction B] containing polyphenols with a mean degree of polymerization (mdp) of less than 3, and a second retentate [Fraction C] enriched in fiber and polyphenols, wherein the polyphenols in Fraction C have a mdp of greater than 5.
