The sweet transformation can last anywhere between 15 minutes to two hours depending on the product and how much you consume in that time. This effect will diminish as the pH of your tongue returns to a neutral state or you consume anything with a high temperature. High temperatures kill the Miraculin protein. For example, if you were to consume a mberry Miracle Fruit Tablet and then drank a cup of hot tea, the Miraculin coating on your tongue would disappear. The protein cannot be exposed to high temperatures and therefore cannot be cooked with either. For supertasters, the effects can last longer. They are individuals with more taste buds. They can have strong likes or dislikes for different foods because they experience stronger flavors.
