| 20090197942 | Method For Producing Polyphenol-Rich Composition - An object of the present invention is to provide a method for producing polyphenol-containing compositions and purifying polyphenols safely and simply. By contacting a polyphenol-containing solution to a specific polysaccharide to support polyphenols with the polysaccharide, a polyphenol-containing composition usable as an additive for foods and drinks can be obtained. In addition, polyphenol can be purified by contacting polysaccharide-supported polyphenols with solvent to elute polyphenols into the solvent and then powderizing the polyphenols after removing the solvent. | 08-06-2009 |
