ActiPureÔ
The ActiPureTM is a patented (patent #5,912,363) natural
extraction process. This process involves a hot water extraction of polyphenolic compounds
(OPCs) from dry grape seeds. Extracted OPCs are selectively purified using food grade
membrane filters and adsorption resins. Active compounds adsorbed on the resin are
reversibly removed using an ethanol/water solution. Food grade membrane filters are
employed to concentrate the OPCs before drying. The finished product consists of a red
powder containing over 80 percent polyphenolics (measured as gallic acid equivalents) and
a potency of greater than 250 Porter units.
Porter refers to an analytical procedure consisting of a
colormetric test to measure OPC content. |
