The papaya // or // (frae Carib via Spanyie), papaw, or pawpaw is the fruit o the plant Carica papaya, the sole species in the genus Carica o the plant faimily Caricaceae. It is native tae the tropics o the Americaes, perhaps frae soothren Mexico an neighbourin Central Americae. It wis first cultivatit in Mexico several centuries afore the emergence o the Mesoamerican classical ceevilizations.
The papaya is a lairge, tree-like plant, wi a single stem growin frae 5 to 10 m (16 to 33 ft) tall, wi spirally arranged leaves confined tae the tap o the trunk. The laicher trunk is conspicuously scarred where leaves an fruit wur borne. The leaves are lairge, 50–70 cm (20–28 in) in diameter, deeply palmately lobed, wi seven lobes. Unusually for such lairge plants, the trees are dioecious. The tree is usually unbranched, unless lopped. The flouers are similar in shape tae the flouers o the Plumeria, but are much smawer an wax-like. Thay appear on the axils o the leaves, maturin intae lairge fruit - 15–45 cm (5.9–17.7 in) lang an 10–30 cm (3.9–11.8 in) in diameter. The fruit is ripe when it feels saft (as saft as a ripe avocado or a bit safter) an its skin haes attained an amber tae orange hue.

Common names[eedit | eedit soorce]
Carica papaya plants an their fruits are kent bi different names aroond the Inglish-speakin warld:
- North Americae an Belize: papayas
- Unitit Kinrick: The fruit is usually cried papaya but is also kent as papaw or pawpaw 
- Africae: pawpaw or papaw 
Cultivation[eedit | eedit soorce]
Originally frae soothren Mexico (particularly Chiapas an Veracruz), Central Americae, an northren Sooth Americae, the papaya is nou cultivatit in maist tropical kintras. In cultivation, it graws rapidly, fruitin within three years. It is, however, heichly frost-sensitive, limitin its production tae tropical lands.
Pests an diseases[eedit | eedit soorce]
- Main airticle: Leet o papaya diseases
Papayas are susceptible tae the papaya ringspot virus (PRV), which causes prematur moltin an malformation o the leaves. In the 1990s, the virus threatened tae wipe oot Hawaii's papaya industry completely.
The papaya is also susceptible tae the fruit flee, a smaa, wasp-like insect that lays its eggs in young fruit.
Cultivars[eedit | eedit soorce]
Twa kinds o papayas are commonly grawn. Ane haes sweet, reid (or orangish) flesh, an the ither haes yellae flesh; in Australie, these are cried "reid papaya" an "yellae papaw", respectively. Either kynd, picked green, is cried a "green papaya."
In 2011 Philippine researchers reportit thay bi intergeneric hybridisation atween carica papaya an Vasconcellea quercifolia thay haed developed conventionally bred, nongenetically engineered papaya that are provin resistant tae PRV.
Genetically modified cultivars[eedit | eedit soorce]
In response tae the PRV ootbreak in Hawaii, genetically altered papaya wur generated an broucht tae mercat (includin 'SunUp' an 'Rainbow') that hae some papaya ringspot virus (PRV) DNA incorporatit intae the DNA o the plant are resistant tae PRVs. This wis so successful that bi 2010, 80% o Hawaiian papaya plants wur genetically modified.
Uises[eedit | eedit soorce]
Meat tenderizin[eedit | eedit soorce]
Baith green papaya fruit an the tree's latex are rich in papain, a protease uised for tenderizin meat an ither proteins. Its ability tae break doun tough meat fibers wis uised for thoosands o years bi indigenous Americans. It is nou includit as a component in powdered meat tenderizers.

Papaya fruit is a soorce o nutrients such as provitamin A carotenoids, vitamin C, folate an dietary fiber. Papaya skin, pulp an seeds also contain a variety o phytochemicals, includin lycopene an polyphenols. In preliminary research, danielone, a phytoalexin foond in papaya fruit, shawed antifungal activity against Colletotrichum gloesporioides, a pathogenic fungus o papaya.
The ripe fruit o the papaya is usually eaten raw, withoot skin or seeds. The unripe green fruit can be eaten cuiked, usually in curries, salads, an stews. Green papaya is uised in Sootheast Asie cuikin, baith raw an cuiked. In Thai cuisine, papaya is uised tae mak Thai salads such as som tam and Thai curries such as kaeng som when still not fully ripe. In Indonesian cuisine, the unripe green fruits an young leaves are boiled for uise as pairt o lalab salad, while the flouer buds are sautéed an stir-fried wi chillies an green tomatoes as Minahasan papaya flouer vegetable dish. Papayas hae a relatively heich amoont o pectin, which can be uised tae mak jellies. The smell o ripe, fresh papaya flesh can strike some fowk as unpleasant.
The black seeds o the papaya are edible an hae a sharp, spicy taste. Thay are sometimes groond an uised as a substitute for black pepper.
In some pairts o the warld, papaya leaves are made intae tea as a treatment for malaria. Antimalarial an antiplasmodial activity haes been notit in some preparations o the plant, but the mechanism is nae unnerstood an no treatment method based on these results haes been scientifically proven.
Yerbal medicine[eedit | eedit soorce]
Papaya is mercatit in tablet fairm tae remedy digestive problems.
Papain is also applied topically in kintras where it graws for the treatment o cuts, rashes, stings an burns. Papain ointment is commonly made frae fermented papaya flesh, an is applied as a gel-like paste. Harrison Ford wis treatit for a ruptured disc incurred durin filmin o Indiana Jones an the Temple o Doom bi papain injections.
Allergies an side effects[eedit | eedit soorce]
Papaya is frequently uised as a hair conditioner, but should be uised in smaa amoonts. Papaya releases a latex fluid when nae quite ripe, which can cause irritation an provoke allergic reaction in some fowk.
The latex concentration o unripe papayas are speculatit tae cause uterine contractions, which mey lead tae a miscarriage. Papaya seed extracts in large doses hae a contraceptive effect on rats an monkeys, but in smaw doses hae no effect on the unbairn ainimals.
Excessive consumption o papaya can cause carotenemia, the yellowin o soles an palms, which is itherwise harmless. However, a very lairge dose would need tae be consumed; papaya contains aboot 6% o the level o beta carotene foond in carrots (the maist common cause o carotenemia).
