The present invention provides a novel process for extraction, purification and concentration of polyphenol substances from whole grapes, grape seeds and grape pomace without the need for membrane filtration. Aspects of several embodiments of the novel processes include hot water extraction, a dual pH treatment of the hot water extracts, and the uses of a copolymer of trimethylolpropane trimethacrylate as an adsorbent resin to maximize the concentration and purification of the beneficial polyphenolic substances.
