Patent ID: 8343565

Claim:
A method to produce an antioxidant grape extract exhibiting an ORAC value of at least 10,000 μmol TE/g, the method including the following steps: (a) drying grape material including at least one of (i) grape fruit, (ii) grape skin, and (iii) grape seed; (b) creating an active crude grape extract solution that includes polyphenols and monomeric phenols, as well as inactive ingredients, by dissolving dried said grape material in ethanol; (c) employing means for separating from said solution created at step (b) at least a fraction of said active crude grape extract without substantially retaining said inactive ingredients; and (d) refining, at least once, active crude grape extract separated at step (c) to collect an extract solution containing polyphenols with a concentration about 70% to about 95% by weight and containing monomeric phenols with a concentration of about 10% to about 45% by weight, to produce said antioxidant grape extract exhibiting an ORAC value of at least 10,000 μmol TE/g.
