Abstract: An antioxidant additive includes one, two, or all three of Matcha, Rooibos and Goji Berry. In a method of making a fused antioxidant additive that includes at least two components, the at least two components are fused together in a fusion process, wherein the at least two components are added to a fusion chamber and stirred together until the volume of the contents of the fusion chamber has decreased by a sufficient amount, thereby indicating that the at least two components have fused to each other. The fused antioxidant additive has unique properties that allow it to be added to coffee beans during roasting. During the coffee roasting process, the fused antioxidant additive is added to the roasting chamber after first crack. Coffee roasted in this manner has an unexpectedly high degree of antioxidant power.
