NATURAL COLOR CONCENTRATES AND ANTIMICROBIAL NUTRACEUTICAL FROM PLANTS

摘要

An active coloring concentrate can be prepared from the juice of cranberries and blueberries by treating juice or homogenate with an appropriate binding matrix. Assorted ion exchange resins such as cholestyramine are effective binding matrices, but the currently preferred material is a food grade of cross-linked polyvinyl pyrollidone. The binding matrices are used to concentrate active materials from cranberry and a colored solid is produced. This substance shows anti-bacterial and anti-viral properties. It can be readily consumed as a therapeutic or nutraceutical, used as a coloring agent, or it can be used topically. Significant amounts of active concentrate can be produced from cranberry presscake which is normally a waste material.
