U.S. Department of Agriculture (USDA) researchers found a sap oozing from the stem of frost grape, a native U.S. grapevine, which has piqued their interest. This sap has an uncanny similarity to gum Arabic, a common thickening agent and emulsifier used in cake frosting, candies, paints, cosmetics and other products.
