Miraculin is a glycoprotein that is known for its ability to alter the perception of taste. It is found in the fruit of the West African plant Synsepalum dulcificum, also known as the miracle fruit. Miraculin has a number of synonyms, including miracle berry protein, dulcin, and taste-modifying protein. Other synonyms for miraculin include berry sweetness protein, sweetness inducer, and sweetener protein. The protein is also sometimes referred to as the miracle fruit protein. Regardless of what it is called, miraculin has the unique ability to transform sour and bitter flavors into sweet ones. This makes it a valuable ingredient in some food products and a fascinating topic of research for scientists who are interested in exploring the complex and multifaceted nature of taste perception.
