Abstract
Abstract A coated straw useful for improving the taste of acidic liquids including carbonated beverages or fruit juices. The inside surface of the straw end inserted in the liquid is coated with a mixture of nontoxic alkaline material and sugar and a separate section of the inside surface is coated with taste-modifying stable miraculin. The amount of alkaline material is sufficient to render nonacid the liquid in the first mouthful.
