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.

Juice extraction using multiple pairs of juice extractors and comminutors which reduce the food pieces into successively smaller pieces with juice extraction occurring after each comminuting step. Coarse food pieces are pressed with extracted juice directed to a juice holding tank. The pressed coarse chop food pieces fall into the hopper of a second comminutor which performs a medium chop on the now pressed but still coarse chopped food pieces. The medium chopped food pieces are then fed from the second comminutor into the juice extraction chamber of a second juice extractor whereupon the medium chopped food pieces are pressed with extracted juice directed to a juice holding tank. Any number of comminutor and juice extraction pairs may be used in serial fashion to optimize the percentage of juice extracted in a minimum amount of time.
