Neoculin, a sweet protein found in the fruit of Curculigo latifolia, has the ability to change sourness into sweetness. Neoculin turns drinking water sweet, indicating that non-acidic compounds may induce the sweetness. We report that ammonium chloride and certain amino acids elicit the intense sweetness of neoculin. Neoculin can thus sweeten amino acid-enriched foods.
