Grape seed extracts and related systems and methods of manufacture

A system for processing a grape seed extract, the system comprising:

• a source for a grape seed extract source material;
• a first filter configured to filter the grape seed extract source material to obtain a first retentate and a first permeate;
• a first dryer configured to dry the first retentate to obtain a first grape seed extract comprising a first mean degree of polymerization;
• a second filter configured to filter the first permeate to obtain a second retentate and a second permeate;
• a second dryer configured to dry the second retentate to obtain a second grape seed extract comprising a second mean degree of polymerization less than the first mean degree of polymerization;
• a purifier configured to purify the second permeate to obtain a purified liquid;
• and
• a third dryer configured to dry the purified liquid to obtain a third grape seed extract comprising a third mean degree of polymerization less than the second mean degree of polymerization.
