How are the seeds stored prior to extraction?
After the seeds are separated from the skins and stems, they are dried to less than 8% moisture and stored in a cool, dry location until processed. What solvents do you use in your extraction process? Water and beverage grade ethanol are the only extraction solvents used. Do you use sulfur dioxide during the processing of your grape skin extracts? Unlike enocianina grape skin extracts from Europe, Polyphenolics does not add sulfur dioxide during the extraction of our grape skins. Therefore, Polyphenolics’ GSKE and GSKE-40 skin extracts contain less than 100 ppm and 75 ppm of sulfur dioxide, respectively, while competitors’ extracts may contain up to 5500 ppm of sulfur dioxide. What is ORAC and how is it done? ORAC stands for Oxygen Radical Absorbance Capacity. In this assay the ability of a substance to subdue oxygen free radicals in vitro or “total antioxidant capacity” is determined. The method is spectrofluorometric, performed by an outside lab (automated), and it is based on the ti
