|The fruit developing on the plant|
Solanum ovigerum Dunal
Eggplant (US,Australia,New Zealand, anglophone Canada), aubergine (UK,Ireland, Quebec, and most of mainland Western Europe) or brinjal (South Asia, Malaysia, South Africa) is a plant species in the nightshade family Solanaceae. Solanum melongena is grown worldwide for its edible fruit.
Most commonly purple, the spongy, absorbent fruit is used in several cuisines. Typically used as a vegetable in cooking, it is a berry by botanical definition. As a member of the genus Solanum, it is related to the tomato, chili pepper, and potato, although they are new world and the eggplant, like nightshade, is old world. Like the tomato, its skin and seeds can be eaten, but, like the potato, it is usually eaten cooked. Eggplant is nutritionally low in macronutrient and micronutrient content, but the capability of the fruit to absorb oils and flavors into its flesh through cooking expands its use in the culinary arts.
It was originally domesticated from the wild nightshade species thorn or bitter apple, S. incanum, probably with two independent domestications: one in South Asia, and one in East Asia. In 2018, China and India combined accounted for 87% of the world production of eggplants.
The eggplant is a delicate, tropical perennial plant often cultivated as a tender or half-hardy annual in temperate climates. The stem is often spiny. The flowers are white to purple in color, with a five-lobed corolla and yellow stamens. Some common cultivars have fruit that is egg-shaped, glossy, and purple with white flesh and a spongy, "meaty" texture. Some other cultivars are white and longer in shape. The cut surface of the flesh rapidly turns brown when the fruit is cut open (oxidation).
Eggplant grows 40 to 150 cm (1 ft 4 in to 4 ft 11 in) tall, with large, coarsely lobed leaves that are 10 to 20 cm (4 to 8 in) long and 5 to 10 cm (2 to 4 in) broad. Semiwild types can grow much larger, to 225 cm (7 ft 5 in), with large leaves over 30 cm (12 in) long and 15 cm (6 in) broad. On wild plants, the fruit is less than 3 cm ( in) in diameter; in cultivated forms: 30 cm (12 in) or more in length are possible for long, narrow types or the large fat purple ones common to the West.
The plant species is believed to have originated in India, where it continues to grow wild, or in Africa. It has been cultivated in southern and eastern Asia since prehistory. The first known written record of the plant is found in Qimin Yaoshu, an ancient Chinese agricultural treatise completed in 544 C.E. The numerous Arabic and North African names for it, along with the lack of the ancient Greek and Roman names, indicate it was grown throughout the Mediterranean area by the Arabs in the early Middle Ages, who introduced it to Spain in the 8th century. A book on agriculture by Ibn Al-Awwam in 12th-century Arabic Spain described how to grow aubergines. Records exist from later medieval Catalan and Spanish.
The aubergine is unrecorded in England until the 16th century. An English botany book in 1597 described the madde or raging Apple:
This plant groweth in Egypt almost everywhere... bringing foorth fruite of the bignes of a great Cucumber.... We have had the same in our London gardens, where it hath borne flowers, but the winter approching before the time of ripening, it perished: notwithstanding it came to beare fruite of the bignes of a goose egge one extraordinarie temperate yeere... but never to the full ripenesse.
Because of the plant's relationship with various other nightshades, the fruit was at one time believed to be extremely poisonous. The flowers and leaves can be poisonous if consumed in large quantities due to the presence of solanine.
The eggplant has a special place in folklore. In 13th-century Italian traditional folklore, the eggplant can cause insanity. In 19th-century Egypt, insanity was said to be "more common and more violent" when the eggplant is in season in the summer.
The plant and fruit have a profusion of English names.
The name eggplant is usual in North American English and Australian English. First recorded in 1763, the word "eggplant" was originally applied to white cultivars, which look very much like hen's eggs (see image). Similar names are widespread in other languages, such as the Icelandic term eggaldin or the Welsh planhigyn ?y.
The white, egg-shaped varieties of the eggplant's fruits are also known as garden eggs, a term first attested in 1811. The Oxford English Dictionary records that between 1797 and 1888, the name vegetable egg was also used.
Whereas eggplant was coined in English, most of the diverse other European names for the plant derive from the Arabic word binj?n (Arabic: ?).Binj?n is itself a loan-word in Arabic, whose earliest traceable origins lie in the Dravidian languages. The Hobson-Jobson dictionary comments that 'probably there is no word of the kind which has undergone such extraordinary variety of modifications, whilst retaining the same meaning, as this'.
In English usage, modern names deriving from Arabic binj?n include:
The Dravidian word was borrowed into the Indic languages, giving ancient forms such as Sanskrit and Pali v?ti?-ga?a (alongside Sanskrit v?tigama) and Prakrit v?i?a?a. According to the entry brinjal in the Oxford English Dictionary, the Sanskrit word v?tin-g?na denoted 'the class (that removes) the wind-disorder (windy humour)': that is, v?tin-g?na came to be the name for eggplants because they were thought to cure flatulence. The modern Hindustani words descending directly from the Sanskrit name are baingan and began.
The Indic word v?ti?-ga?a was then borrowed into Persian as b?ding?n. Persian b?ding?n was borrowed in turn into Arabic as binj?n (or, with the definite article, al-binj?n). From Arabic, the word was borrowed into European languages.
The Spanish word alberenjena was then borrowed into French, giving aubergine (along with French dialectal forms like albergine, albergaine, albergame, and belingèle). The French name was then borrowed into British English, appearing there first in the late eighteenth century.
Through the colonial expansion of Portugal, the Portuguese form bringella was borrowed into a variety of other languages:
Thus although Indian English brinjal ultimately originates in languages of the Indian Subcontinent, it actually came into Indian English via Portuguese.
The Arabic word binj?n was borrowed into Greek by the eleventh century CE. The Greek loans took a variety of forms, but crucially they began with m-, partly because Greek lacked the initial b- sound and partly through folk-etymological association with the Greek word (melas), 'black'. Attested Greek forms include ? (matizanion, eleventh-century), ? (melintzana, fourteenth-century), and (melintzanion, seventeenth-century).
These forms also gave rise to the Caribbean English melongene.
The Italian melanzana, through folk-etymology, was adapted to mela insana ('mad apple'): already by the thirteenth century, this name had given rise to a tradition that eggplants could cause insanity. Translated into English as 'mad-apple', 'rage-apple', or 'raging apple', this name for eggplants is attested from 1578 and the form 'mad-apple' may still be found in Southern American English.
It has been known as 'Jew's apple', apparently in relation to a belief that the fruit was first imported to the West Indies by Jewish people.

Different cultivars of the plant produce fruit of different size, shape, and color, though typically purple. The less common white varieties of eggplant are also known as Easter white eggplants, garden eggs, Casper or white eggplant. The most widely cultivated varieties--cultivars--in Europe and North America today are elongated ovoid, 12-25 cm (-10 in) long and 6-9 cm (- in) broad with a dark purple skin.
A much wider range of shapes, sizes, and colors is grown in India and elsewhere in Asia. Larger cultivars weighing up to a kilogram (2.2 pounds) grow in the region between the Ganges and Yamuna Rivers, while smaller ones are found elsewhere. Colors vary from white to yellow or green, as well as reddish-purple and dark purple. Some cultivars have a color gradient--white at the stem, to bright pink, deep purple or even black. Green or purple cultivars with white striping also exist. Chinese cultivars are commonly shaped like a narrower, slightly pendulous cucumber. Also, Asian cultivars of Japanese breeding are grown.
Bt brinjal is a transgenic eggplant that contains a gene from the soil bacterium Bacillus thuringiensis. This variety was designed to give the plant resistance to lepidopteran insects such as the brinjal fruit and shoot borer (Leucinodes orbonalis) and fruit borer (Helicoverpa armigera).
On 9 February 2010, the Environment Ministry of India imposed a moratorium on the cultivation of Bt brinjal after protests against regulatory approval of cultivated Bt brinjal in 2009, stating the moratorium would last "for as long as it is needed to establish public trust and confidence". This decision was deemed controversial, as it deviated from previous practices with other genetically modified crops in India. Bt brinjal was approved for commercial cultivation in Bangladesh in 2013.
Raw eggplant can have a bitter taste, with an astringent quality, but it becomes tender when cooked and develops a rich, complex flavor. Rinsing, draining, and salting the sliced fruit before cooking may remove the bitterness. The fruit is capable of absorbing cooking fats and sauces, which may enhance the flavor of eggplant dishes.
Eggplant is used in the cuisines of many countries. Due to its texture and bulk, it is sometimes used as a meat substitute in vegan and vegetarian cuisines. Eggplant flesh is smooth. Its numerous seeds are small, soft and edible, along with the rest of the fruit, and do not have to be removed. Its thin skin is also edible, and so it does not have to be peeled. However, the green part at the top, the calyx, does have to be removed when preparing an eggplant for cooking.
Eggplant can be steamed, stir-fried, pan fried, deep fried, barbecued, roasted, stewed, curried, or pickled. Many eggplant dishes are sauces made by mashing the cooked fruit. It can be stuffed. It is frequently, but not always, cooked with fat.
Korean and Japanese eggplant varieties are typically thin-skinned.
In Chinese cuisine, eggplants are known as qiézi (). They are often deep fried and made into dishes such as yúxi?ng-qiézi ("fish fragrance eggplant") or di s?n xi?n ("three earthen treasures"). Elsewhere in China, such as in Yunnan cuisine (in particular the cuisine of the Dai people) they are barbecued or roasted, then split and either eaten directly with garlic, chilli, oil and coriander, or the flesh is removed and pounded to a mash (typically with a wooden pestle and mortar) before being eaten with rice or other dishes.
In Japanese cuisine, eggplants are known as nasu or nasubi and use the same characters as Chinese (). An example of it use is in the dish hasamiyaki (?) in which slices of eggplant are grilled and filled with a meat stuffing. Eggplants also feature in several Japanese expression and proverbs, such as "Don't feed autumn eggplant to your wife" (?, akinasu ha yomi ni kuwasuna) and "Always listen to your parents" (, oya no iken to nasubi no hana ha sen ni hitotsu mo muda ha nai, literally: "not even one in a thousand of a parents' opinion or an eggplant flower are in vain").

In the Philippines, eggplants are of the long and slender purple variety. They are known as talong and is widely used in many stew and soup dishes, like pinakbet. However the most popular eggplant dish is tortang talong, an omelette made from grilling an eggplant, dipping it into beaten eggs, and pan-frying the mixture. The dish is characteristically served with the stalk attached. The dish has several variants, including rellenong talong which is stuffed with meat and vegetables. Eggplant can also be grilled, skinned and eaten as a salad called ensaladang talong. Another popular dish is adobong talong, which is diced eggplant prepared with vinegar, soy sauce, and garlic as an adobo.

Eggplant is widely used in its native India, for example in sambar (a tamarind lentil stew), dalma (a dal preparation with vegetables, native to Odisha), chutney, curry, and achaar (a pickled dish). Owing to its versatile nature and wide use in both everyday and festive Indian food, it is often described as the "king of vegetables". Roasted, skinned, mashed, mixed with onions, tomatoes, and spices, and then slow cooked gives the South Asian dish baingan bharta or gojju, similar to salat? de vinete in Romania. Another version of the dish, begun-pora (eggplant charred or burnt), is very popular in Bangladesh and the east Indian states of Odisha and West Bengal where the pulp of the vegetable is mixed with raw chopped shallot, green chilies, salt, fresh coriander, and mustard oil. Sometimes fried tomatoes and deep-fried potatoes are also added, creating a dish called begun bhorta. In a dish from Maharashtra called bharli vangi, small brinjals are stuffed with ground coconut, peanuts, onions, tamarind, jaggery and masala spices, and then cooked in oil. Maharashtra and the adjacent state of Karnataka also have an eggplant-based vegetarian pilaf called 'vangi bhat' ..
Eggplant is often stewed, as in the French ratatouille, or deep-fried as in the Italian parmigiana di melanzane, the Turkish karn?yar?k, or Turkish, Greek, and Levantine musakka/moussaka, and Middle Eastern and South Asian dishes. Eggplants can also be battered before deep-frying and served with a sauce made of tahini and tamarind. In Iranian cuisine, it is blended with whey as kashk e bademjan, tomatoes as mirza ghassemi, or made into stew as khoresht-e-bademjan. It can be sliced and deep-fried, then served with plain yogurt (optionally topped with a tomato and garlic sauce), such as in the Turkish dish patl?can k?zartmas? (meaning fried aubergines), or without yogurt, as in patl?can ?ak?uka. Perhaps the best-known Turkish eggplant dishes are imam bay?ld? (vegetarian) and karn?yar?k (with minced meat). It may also be roasted in its skin until charred, so the pulp can be removed and blended with other ingredients, such as lemon, tahini, and garlic, as in the Arab baba ghanoush and the similar Greek melitzanosalata. A mix of roasted eggplant, roasted red peppers, chopped onions, tomatoes, mushrooms, carrots, celery, and spices is called zacusc? in Romania, and ajvar or pinjur in the Balkans.
A Spanish dish called escalivada in Catalonia calls for strips of roasted aubergine, sweet pepper, onion, and tomato. In Andalusia, eggplant is mostly cooked thinly sliced, deep-fried in olive oil and served hot with honey (berenjenas a la Cordobesa). In the La Mancha region of central Spain, a small eggplant is pickled in vinegar, paprika, olive oil, and red peppers. The result is berenjena of Almagro, Ciudad Real. A Levantine specialty is makdous, another pickling of eggplants, stuffed with red peppers and walnuts in olive oil. Eggplant can be hollowed out and stuffed with meat, rice, or other fillings, and then baked. In Georgia, for example, it is fried and stuffed with walnut paste to make nigvziani badrijani.
In tropical and subtropical climates, eggplant can be sown in the garden. Eggplant grown in temperate climates fares better when transplanted into the garden after all danger of frost has passed. Eggplant prefers hot weather, and when grown in cold climates or in areas with low humidity, the plants languish or fail to set and produce mature fruit. Seeds are typically started eight to 10 weeks prior to the anticipated frost-free date. S. melongena is included on a list of low flammability plants, indicating that it is suitable for growing within a building protection zone.
Spacing should be 45 to 60 cm (18 to 24 in) between plants, depending on cultivar, and 60 to 90 cm (24 to 35 in) between rows, depending on the type of cultivation equipment being used. Mulching helps conserve moisture and prevent weeds and fungal diseases and the plants benefit from some shade during the hottest part of the day. Hand pollination by shaking the flowers improves the set of the first blossoms. Growers typically cut fruits from the vine just above the calyx owing to the somewhat woody stems. Flowers are complete, containing both female and male structures, and may be self- or cross-pollinated.
Many of the pests and diseases that afflict other solanaceous plants, such as tomato, capsicum, and potato, are also troublesome to eggplants. For this reason, it should generally not be planted in areas previously occupied by its close relatives. However, since eggplants can be particularly susceptible to pests such as whiteflies, they are sometimes grown with slightly less susceptible plants, such as chili pepper, as a sacrificial trap crop. Four years should separate successive crops of eggplants to reduce pest pressure.
Common North American pests include the potato beetles, flea beetles, aphids, whiteflies, and spider mites. Good sanitation and crop rotation practices are extremely important for controlling fungal disease, the most serious of which is Verticillium.
(millions of tonnes)

In 2018, world production of eggplants was 54 million tonnes, led by China with 63% of the total and India with 24% (table).
Raw eggplant is 92% water, 6% carbohydrates, 1% protein, and has negligible fat (table). It provides low amounts of essential nutrients, with only manganese having a moderate percentage (11%) of the Daily Value. Minor changes in nutrient composition occur with season, environment of cultivation (open field or greenhouse), and genotype.
The potato tuber moth (Phthorimaea operculella) is an oligophagous insect that prefers to feed on plants of the family Solanaceae such as eggplants. Female P. operculella use the leaves to lay their eggs and the hatched larvae will eat away at the mesophyll of the leaf.
Case reports of itchy skin or mouth, mild headache, and stomach upset after handling or eating eggplant have been reported anecdotally and published in medical journals (see also oral allergy syndrome).
A 2008 study of a sample of 741 people in India, where eggplant is commonly consumed, found nearly 10% reported some allergic symptoms after consuming eggplant, with 1.4% showing symptoms within two hours. Contact dermatitis from eggplant leaves and allergy to eggplant flower pollen have also been reported.
Individuals who are atopic (genetically predisposed to developing certain allergic hypersensitivity reactions) are more likely to have a reaction to eggplant, which may be because eggplant is high in histamines. A few proteins and at least one secondary metabolite have been identified as potential allergens. Cooking eggplant thoroughly seems to preclude reactions in some individuals, but at least one of the allergenic proteins survives the cooking process.
The eggplant is quite often featured in the older scientific literature under the junior synonyms S. ovigerum and S. trongum. Several other names that are now invalid have been uniquely applied to it:
A number of subspecies and varieties have been named, mainly by Dikii, Dunal, and (invalidly) by Sweet. Names for various eggplant types, such as agreste, album, divaricatum, esculentum, giganteum, globosi, inerme, insanum, leucoum, luteum, multifidum, oblongo-cylindricum, ovigera, racemiflorum, racemosum, ruber, rumphii, sinuatorepandum, stenoleucum, subrepandum, tongdongense, variegatum, violaceum, viride, are not considered to refer to anything more than cultivar groups at best. However, Solanum incanum and cockroach berry (S. capsicoides), other eggplant-like nightshades described by Linnaeus and Allioni, respectively, were occasionally considered eggplant varieties, but this is not correct.
The eggplant has a long history of taxonomic confusion with the scarlet and Ethiopian eggplants (Solanum aethiopicum), known as gilo and nakati, respectively, and described by Linnaeus as S. aethiopicum. The eggplant was sometimes considered a variety violaceum of that species. S. violaceum of de Candolle applies to Linnaeus' S. aethiopicum. An actual S. violaceum, an unrelated plant described by Ortega, included Dunal's S. amblymerum and was often confused with the same author's S. brownii.
Like the potato and S. lichtensteinii, but unlike the tomato, which then was generally put in a different genus, the eggplant was also described as S. esculentum, in this case once more in the course of Dunal's work. He also recognized the varieties aculeatum, inerme, and subinerme at that time. Similarly, H.C.F. Schuhmacher and Peter Thonning named the eggplant as S. edule, which is also a junior synonym of sticky nightshade (S. sisymbriifolium). Scopoli's S. zeylanicum refers to the eggplant, and that of Blanco to S. lasiocarpum.
Eggplant, which originated in Africa, first shows up in history in Southeast Asia, and it was possibly brought to Iran in the same period from India via the Turks of Central Asia.Cite journal requires
