It is related to the
lycheeand the longan, and is an evergreen treethat grows about 10 metres tall, with a short trunkand a dense crown. The leaves are pinnate,cite book | first= | last= | authorlink= | coauthors=Vinken Pierre; Bruyn GW | year=1995 | title=Intoxications of the Nervous System | edition= | publisher=Elsevier Science B.V. | location=Amsterdam, Netherlands | id=ISBN 0-444-81284-9 ] leathery, compound, 15–30 centimetres long, with 6–10 elliptical obovate-oblong leaflets. Each leaflet is 8–12 centimetres long and 5–8 centimetres broad.
flowers are unisexualand fragrant.

When it ripens, it turns from green to a bright red to yellow-orange, and splits open to reveal three large, shiny black seeds, surrounded by soft, creamy or spongy, white to yellow flesh— arilli.The fruit typically weighs 100–200 grams.
The scientific name honours
Captain William Blighwho took the fruit from Jamaicato Englandin 1793 and introduced it to science. The fruitwas imported to Jamaica from West Africa(probably on a slave ship) before 1778.cite web | author= | year=| title=This is Jamaica | format=HTML | work=National Symbols of Jamaica | url= http://www.jis.gov.jm/special_sections/This%20Is%20Jamaica/symbols.html | accessdate=2006-06-04] Since then it has become a major feature of various Caribbean cuisines, and is also cultivated in tropical and subtropical areas elsewhere around the world. The term 'ackee' originated from the Twilanguage.cite book | first=Allan | last=Metcalf | authorlink= | coauthors= | year=1999 | title=The World in So Many Words | edition= | publisher= | location= | id=ISBN 0-395-95920-9 ] Other names and variant spellings include Ackee, Akee, akee apple, Achee, or "vegetable brain".
Cultivation and uses
Ackee was first introduced to
Jamaicaand later to Haiti, Cuba, Puerto Rico, Barbadosand others. It was later introduced to Floridain the United States.
The oil of the ackee
arils contains many important nutrients, especially fatty acids. Linoleic, palmitic and stearic acids are the primary fatty acids found in the fruit.cite web | author= | year=| title=Jamaican Ackee | format= | work=| url=http://wwwchem.uwimona.edu.jm:1104/lectures/ackee.html | accessdate=2006-06-02] Ackee oil makes an important contribution to the diet of many Jamaicans.

Preparing Ackees for consumption
The fruit of the Ackee is not edible in its entirety. Only the inner, fleshy yellow arils are consumed. The shiny black seeds at the tips of the arils, and the bright red pod enclosing 3 or 4 arils are discarded. Ackees must be harvested, prepared and cooked properly. Ackee pods should be allowed to ripen and open naturally on the tree before picking. Prior to cooking, the ackee arils must be cleaned, washed, boiled and the water discarded: unripe ackees and the inner red tissue of the ripe ackee arils contain potent alkaloid toxins (Hypoglycins A and B) which can produce a syndrome of vomiting, seizures and fatal hypoglycemia known as Jamaican vomiting sickness. Though it may be poisonous when improperly prepared, ackee has high nutritional value and is rich in essential fatty acids, vitamin A, zinc, and protein. They also make delicious fare when sauteed with onions, tomatoes and salted codfish in the Jamaican national dish and perennial dinner favorite "ackee and saltfish".
Biochemistry of Ackee poisoning
The unripened or inedible portions of the fruit contain the
toxins hypoglycin A and hypoglycin B. Hypoglycin A is found in both the seeds and the arilli, while hypoglycin B is found only in the seeds. Hypoglycinis converted in the body to methylenecyclopropyl acetic acid(MCPA). Hypoglycin and MCPA are both toxic. MCPA inhibits several enzymes involved in the breakdown of acyl CoAcompounds. Hypoglycin binds irreversibly to coenzyme A, carnitineand carnitine acyltransferases I and IIcite book | first= Parveen J.| last= Kumar | authorlink= | coauthors= | year=2006 | title= Clinial Medicine | edition= 5| publisher=Saunders (W.B.) Co Ltd | location= | id=ISBN 978-0702025792 ] reducing their bioavailability and consequently inhibiting beta oxidationof fatty acids. Beta oxidation normally provides the body with ATP, NADH and acetyl CoAwhich is used to supplement the energy produced by glycolysis. Glucose stores are consequently depleted leading to hypoglycemia.cite book | first= Vishwanath | last= SarDesai | title=Introduction to Clinical Nutrition | publisher=Marcel Dekker Inc. | location=New York | year=2003 | id=ISBN 0-8247-4093-9]
The ackee fruit is
cannedand is a major export product in Jamaica. In 2005 the ackee industry was valued at $400 million in the island.cite web | title=Viable Ackee Industry must be Protected- BSJ Inspector | work= | url=http://www.jis.gov.jm/agriculture/html/20060506T100000-0500_8777_JIS_VIABLE_ACKEE_INDUSTRY_MUST_BE_PROTECTED__BSJ_INSPECTOR.asp | accessdate=2006-06-02] The importing of canned ackee into the U.S. has at times been restricted due to unripe ackee arilli being included. However, it is currently allowed, provided that the amount of hypoglycin present meets the standards of the Food and Drug Administration.In 2005 the first commercial shipments of canned ackee from Haiti were approved by the US-FDA for shipment to the US market.

The canning plant in
Port-au-Princeis supplied with fruit from three commercial orchards on the outskirts of the city.
