The Sweet Effects of Miracle Fruit

Key Takeaways

• Miraculin is a glycoprotein responsible for the fruit’s taste-altering activity and was isolated in 1968.
• Receptor-level binding on taste buds enables acidic stimuli to be perceived as sweet rather than sour.
• The effect is time-limited, typically persisting for 30 minutes to two hours after exposure.
• Practical relevance includes noncaloric sweetness perception, potentially applicable to settings where taste modulation is desirable.
