How does it work? The protein Miraculin, resides within the pulp of the fruit and as it is consumed the protein binds to all of the 10,000 taste buds that are on the tongue. Within each taste bud are around 50-100 taste cells. Transduction of the taste buds occurs when chemicals are in contact with the receptor sites located on the tips of taste cells. The electrical signals produced are then transmitted from the tongue to multiple nerves, ending up to the thalamus and the frontal lobe. This being a part of processing after the receptors are activated. As the Miraculin coats each taste bud, when a stimulus is introduced it actually alters the shape of the taste bud and only allows the receptors to identify acids as sugars which temporarily changes perception.
