Polyphenolics Receives Patent for Unique Manufacturing Extraction Process

Patented process gives MegaNatural™ Gold Grape Seed Extract greater bioavailability and solubility

The U.S. Patent and Trademark Office has issued Patent No.6,544,581 to Canandaigua Wine Company, in connection with its Polyphenolics business, for its unique manufacturing extraction process. The process gives the company's MegaNaturalTM Gold Grape Seed Extract a much lower average molecular weight than any other grape seed extract on the market, increasing its heart-healthy benefits.

The lower molecular weight makes MegaNatural™ easier for the body to absorb, improving its bioactivity and its ability to prevent LDL oxidation. It also makes MegaNatural™ Gold extremely water soluble, an ideal quality for the beverage industry.

"We are extremely pleased with this innovation," explained Anil Shrikhande, Ph.D., President of Polyphenolics, "since this process allows us to use an aqueous extraction of procyanidins from grape materials without the use of organic solvents used by other processors."

"We are very excited about this new patented process," said Ron Martin, Vice President of Sales. "This puts us in the unique position of being able to provide our customers with a consistent, high quality product that yields better cardiovascular protection per gram than other similar products on the market."

The patented process isolates and concentrates the bioactive phenolic and flavonoid substances in the rubired and white varietal grape seeds used in the process. This powdered extract contains phenols at a concentration several times that found in commercial concord grape juice.

Polyphenolics, a division of Canandaigua Wine Company, manufactures, markets and sells ingredients for the pharmaceutical, nutritional and beverage industries. For more information call (219) 243-9825 or visit
