Synsepalum dulcificum – Wikipedia

Plant from West Africa with a taste-modifying berry
Synsepalum dulcificum is a plant within the Sapotaceae household, native to tropical Africa. It’s recognized for its berry that, when eaten, causes sour meals (corresponding to lemons and limes) subsequently consumed to style sweet. This impact is because of miraculin. Common names for this species and its berry embrace miracle fruit,[3] miracle berry, miraculous berry,[3] candy berry,[4][5][6] and in West Africa, the place the species originates, agbayun (in Yoruba),[7][8] taami, asaa, and ledidi.
The berry itself has a low sugar content material [9] and a mildly candy tang. It incorporates a glycoprotein molecule, with some trailing carbohydrate chains, known as miraculin.[10] When the fleshy part of the fruit is eaten, this molecule binds to the tongue’s taste buds, inflicting bitter meals to style candy. At impartial pH, miraculin binds and blocks the receptors, however at low pH (ensuing from ingestion of bitter meals) miraculin binds proteins and turns into capable of activate the candy receptors, ensuing within the notion of candy style.[11] This impact lasts till the protein is washed away by saliva (as much as about half-hour).[12]
The names miracle fruit and miracle berry are shared by Gymnema sylvestre and Thaumatococcus daniellii,[3] that are two different species used to change the perceived sweetness of meals.
Historical past[edit]
The berry has been utilized in West Africa for a very long time. It is part of the food plan of the Yoruba people.[7] Outsiders started studying this fruit since a minimum of the 18th century, when a European explorer, the Chevalier des Marchais, offered an account of its use there. Des Marchais, who was looking out West Africa for a lot of totally different fruits in a 1725 tour, observed that native individuals picked the berry from shrubs and chewed it earlier than meals.
Within the Nineteen Eighties in the USA, an try was made to commercialize the fruit for its means to masks non-sweet meals as candy with out a caloric value, however turned compromised when the Food and Drug Administration categorised the berry as a food additive and required proof of security.[9][13][14] For a time within the Seventies, US dieters may buy a tablet type of miraculin.[15] This curiosity had a revival in food-tasting occasions at which tasters eat bitter and bitter meals, corresponding to lemons, radishes, pickles, hot sauce, and beer, then expertise the perceived change to sweetness with miraculin.[16]
Traits[edit]
It’s a shrub that grows 1.8–4.5 m (5.9–14.8 ft) in peak and has dense foliage.[17][18] Its leaves are 5–10 cm (2.0–3.9 in) lengthy, 2.0–3.7 cm (0.79–1.46 in) vast, and glabrous under. They’re clustered on the ends of the branchlets. The flowers are white. It carries pink, 2 cm (0.79 in) lengthy fruits. Every fruit incorporates one seed.[5]
Cultivation[edit]

The plant grows finest in soils with a pH as little as 4.5 to five.8, in an surroundings free from frost and in partial shade with excessive humidity. It’s tolerant of drought, full sunshine, and slopes.[5]
The seeds want 14 to 21 days to germinate. A spacing of 4 m (13 ft) between vegetation is usually recommended.[5]
The vegetation first bear fruit after rising about 3–4 years,[5] and produce two crops per 12 months, after the tip of the rainy season. This evergreen plant produces small, pink berries, whereas white flowers are produced for a lot of months of the 12 months.
The seeds are in regards to the measurement of coffee beans.
In Africa, leaves are attacked by lepidopterous larvae, and fruits are infested with larvae of fruit flies. The fungus Rigidoporus microporus has been discovered on this plant.[5]
Transgenic tomato vegetation have been developed in analysis initiatives that produce miraculin.[19][20]
Makes use of and regulation[edit]
In tropical West Africa, the place this species originates, the fruit pulp is used to sweeten palm wine.[21] Traditionally, it was additionally used to enhance the flavour of soured cornbread,[8] however has been used as a sweetener and flavoring agent for numerous drinks and meals, corresponding to beer, cocktails, vinegar, and pickles.[22]
Since 2011, the USA FDA has imposed a ban on importing Synsepalum dulcificum (specifying ‘miraculin’) from its origin in Taiwan, declaring it as an “unlawful undeclared sweetener”. Nonetheless the ban doesn’t apply when it’s imported from different international locations.[23] In 2021, the corporate Baïa Meals Co. in Spain was granted to place Dried Miracle Berry in the marketplace within the EU.

The berries include miraculin, a rogue glycoprotein that tips the tongue’s taste-bud receptors into believing a bitter meals is definitely candy. Individuals in components of west Africa have been utilizing the berries to sweeten bitter food and drinks for hundreds of years, however it’s only not too long ago that the worldwide meals trade has cottoned on.
