St. Patrick’s Day is a day when we celebrate the Irish in all (or at least 35 million) of us. We honor our Irish ancestors, relatives and friends by dressing in green, visiting an Irish pub, or participating in a festive parade.
Food manufacturers also observe St. Patrick’s Day through the creative use of food coloring, which is regulated by the U.S. Food and Drug Administration. Pigments used to color food and derived from vegetables, minerals or animals are exempt from certification. A natural source of green food coloring would be grape skin extract.
