Abstract
Abstract A mouthpiece construction having a tip and a mouthpiece adapted to fit with a straw. The tip is coated with an effervescent taste-modifying composition comprising an effective amount of room temperature stable taste modifying principle known as miraculin obtained from the ripe fruit of Synsepalum dulcificum Daniell, and a non-toxic alkaline material capable of forming carbon dioxide when dissolved in an aqueous acidic solution. The coating is sealed from the atmosphere and the interior of the mouthpiece. The mouthpiece has a lengthwise passageway which fits with the interior of a straw and radial passageway which connects the lengthwise passageway and the peripheral surface of the mouthpiece. The radial passageways are positioned so that liquid passing out of them contacts the coating.
