Mango
The mango is a juicy stone fruit (drupe) belonging to the genus Mangifera, consisting of numerous tropical fruiting trees, cultivated mostly for edible fruit. The majority of these species are found in nature as wild mangoes. They all belong to the flowering plant familyAnacardiaceae. The mango is native to South Asia,[1][2] from where it has been distributed worldwide to become one of the most cultivated fruits in the tropics. The center of diversity of the Mangifera genus is in India.[1]
While other Mangifera species (e.g. horse mango, Mangifera foetida) are also grown on a more localized basis, Mangifera indica—the "common mango" or "Indian mango"—is the only mango tree commonly cultivated in many tropical and subtropical regions.
It is the national fruit of India, Pakistan, and the Philippines, and the national tree ofBangladesh.[3]
Description

Mango trees grow up to 35–40 m (115–131 ft) tall, with a crown radius of 10 m (33 ft). The trees are long-lived, as some specimens still fruit after 300 years.[4] In deep soil, the taproot descends to a depth of 6 m (20 ft), with profuse, wide-spreading feeder roots; the tree also sends down many anchor roots, which penetrate several feet of soil. The leaves are evergreen, alternate, simple, 15–35 cm (5.9–13.8 in) long, and 6–16 cm (2.4–6.3 in) broad; when the leaves are young they are orange-pink, rapidly changing to a dark, glossy red, then dark green as they mature. The flowers are produced in terminalpanicles 10–40 cm (3.9–15.7 in) long; each flower is small and white with five petals 5–10 mm (0.20–0.39 in) long, with a mild, sweet odor suggestive of lily of the valley. Over 400 varieties of mangoes are known, many of which ripen in summer, while some give double crop.[5] The fruit takes three to six months to ripen.
The ripe fruit varies in size and color.Cultivars are variously yellow, orange, red, or green, and carry a single flat, oblong pit that can be fibrous or hairy on the surface, and which does not separate easily from the pulp. Ripe, unpeeled mangoes give off a distinctiveresinous, sweet smell. Inside the pit 1–2 mm (0.039–0.079 in) thick is a thin lining covering a single seed, 4–7 cm (1.6–2.8 in) long. The seed contains the plant embryo. Mangoes have recalcitrant seeds; they do not survive freezing and drying.[6]
Etymology
The mango illustrated by Michael Boym in the 1656 book Flora Sinensis.
The English word "mango" (plural "mangoes" or "mangos") originated from the Malayalamword māṅṅa via Portuguese (also manga) during spice trade with Kerala in 1498.[7][8]The word's first recorded attestation in a European language was a text by Ludovico di Varthema in Italian in 1510, as manga; the first recorded occurrences in languages such as French and postclassical Latin appear to be translations from this Italian text. The origin of the "-o" ending in English is unclear.[9] Mango is also mentioned byHendrik van Rheede, the Dutch commander of Malabar (Northern Kerala) in his bookHortus Malabaricus, a compendium of the plants of economic and medical value in the Malabar, published in 1678.[10] When mangoes were first imported to the American colonies in the 17th century, they had to bepickled because of lack of refrigeration. Other fruits were also pickled and came to be called "mangoes", especially bell peppers, and by the 18th century, the word "mango" became a verb meaning "to pickle".[11]
Cultivation

Mangoes have been cultivated in South Asia for thousands of years[12] and reached East Asia between the fifth and fourth centuries BC. By the 10th century AD, cultivation had begun in East Africa.[12] The 14th-centuryMoroccan traveler Ibn Battuta reported it atMogadishu.[13] Cultivation came later toBrazil, Bermuda, the West Indies, and Mexico, where an appropriate climate allows its growth.[12]
The mango is now cultivated in most frost-free tropical and warmer subtropical climates; almost half of the world's mangoes are cultivated in India alone, with the second-largest source being China.[14][15][16] Mangoes are also grown in Andalusia, Spain (mainly inMálaga province), as its coastal subtropical climate is one of the few places in mainland Europe that permits the growth of tropical plants and fruit trees. The Canary Islands are another notable Spanish producer of the fruit. Other cultivators include North America (in South Florida and California's Coachella Valley), South and Central America, theCaribbean, Hawai'i, south, west, and central Africa, Australia, China, South Korea, Pakistan, Bangladesh, and Southeast Asia. Though India is the largest producer of mangoes, it accounts for less than 1% of the international mango trade; India consumes most of its own production.[17][18][19]
Many commercial cultivars are grafted on to the cold-hardy rootstock of Gomera-1 mango cultivar, originally from Cuba. Its root system is well adapted to a coastal Mediterranean climate.[20] Many of the 1,000+ mango cultivars are easily cultivated using grafted saplings, ranging from the "turpentine mango" (named for its strong taste of turpentine[21]) to the huevos de toro.[citation needed] Dwarf or semidwarf varieties serve as ornamental plants and can be grown in containers. Awide variety of diseases can afflict mangoes.
Cultivars
Main article: List of mango cultivars
There are many hundreds of named mangocultivars. In mango orchards, several cultivars are often grown in order to improve pollination. Many desired cultivars aremonoembryonic and must be propagated bygrafting or they do not breed true. A common monoembryonic cultivar is 'Alphonso', an important export product, considered as "the king of mangoes".[22]
Cultivars that excel in one climate may fail elsewhere. For example, Indian cultivars such as 'Julie', a prolific cultivar in Jamaica, require annual fungicide treatments to escape the lethal fungal disease anthracnose in Florida. Asian mangoes are resistant to anthracnose.
The current world market is dominated by the cultivar 'Tommy Atkins', a seedling of 'Haden'that first fruited in 1940 in southern Florida and was initially rejected commercially by Florida researchers.[23] Growers and importers worldwide have embraced the cultivar for its excellent productivity and disease resistance, shelf life, transportability, size, and appealing color.[24] Although the Tommy Atkins cultivar is commercially successful, other cultivars may be preferred by consumers for eating pleasure, such as Alphonso.[22][24]
Generally, ripe mangoes have an orange-yellow or reddish peel and are juicy for eating, while exported fruit are often picked while underripe with green peels. Although producing ethylene while ripening, unripened exported mangoes do not have the same juiciness or flavor as fresh fruit.
Like other drupaceous fruits, mangoes occur in both freestone and clingstonevarieties.[citation needed]
Production
In 2013, world production of mangoes (data including mangosteens and guavas) was nearly 43 million tonnes, with India accounting for 42% (18 million tonnes) of the total (table).[25] China and Thailand were the next largest producers (table).

Food
Mangoes are generally sweet, although the taste and texture of the flesh varies across cultivars; some have a soft, pulpy texture similar to an overripe plum, while others are firmer, like a cantaloupe or avocado, and some may have a fibrous texture. The skin of unripe, pickled, or cooked mango can be consumed, but has the potential to cause contact dermatitis of the lips, gingiva, or tongue in susceptible people.
Cuisine

Mangoes are widely used in cuisine. Sour, unripe mangoes are used in chutneys, athanu,pickles,[26] side dishes, or may be eaten raw with salt, chili, or soy sauce. A summer drink called aam panna comes from mangoes. Mango pulp made into jelly or cooked with red gram dhal and green chillies may be served with cooked rice. Mango lassi is popular throughout South Asia,[27] prepared by mixing ripe mangoes or mango pulp withbuttermilk and sugar. Ripe mangoes are also used to make curries. Aamras is a popular thick juice made of mangoes with sugar or milk, and is consumed with chapatis or pooris. The pulp from ripe mangoes is also used to make jam called mangada. Andhra aavakaayais a pickle made from raw, unripe, pulpy, and sour mango, mixed with chili powder,fenugreek seeds, mustard powder, salt, andgroundnut oil. Mango is also used in Andhrato make dahl preparations. Gujaratis use mango to make chunda (a grated mango delicacy).
Mangoes are used in preserves such asmoramba, amchur (dried and powdered unripe mango), and pickles, including a spicy mustard-oil pickle and alcohol. Ripe mangoes are often cut into thin layers, desiccated, folded, and then cut. These bars are similar to dried guava fruit bars available in some countries. The fruit is also added to cereal products such as muesli and oat granola. Mangoes are often prepared charred in Hawaii.
Unripe mango may be eaten with bagoong(especially in the Philippines), fish sauce, or with dash of salt. Dried strips of sweet, ripe mango (sometimes combined with seedlesstamarind to form mangorind) are also popular. Mangoes may be used to make juices, mangonectar, and as a flavoring and major ingredient in ice cream and sorbetes.
Mango is used to make juices, smoothies, ice cream, fruit bars, raspados, aguas frescas,pies, and sweet chili sauce, or mixed withchamoy, a sweet and spicy chili paste. It is popular on a stick dipped in hot chili powder and salt or as a main ingredient in fresh fruit combinations. In Central America, mango is either eaten green mixed with salt, vinegar,black pepper, and hot sauce, or ripe in various forms. Toasted and ground pumpkin seed (pepita) with lime and salt are eaten with green mangoes.[citation needed]
Pieces of mango can be mashed and used as a topping on ice cream or blended with milk and ice as milkshakes. Sweet glutinous rice is flavored with coconut, then served with sliced mango as a dessert. In other parts of Southeast Asia, mangoes are pickled withfish sauce and rice vinegar. Green mangoes can be used in mango salad with fish sauce and dried shrimp. Mango with condensed milk may be used as a topping for shaved ice.
Food constituents
Nutrients
The energy value per 100 g (3.5 oz) serving of the common mango is 250 kJ (60 kcal), and that of the apple mango is slightly higher (330 kJ (79 kcal) per 100 g). Fresh mango contains a variety of nutrients (right table), but only vitamin C and folate are in significant amounts of the Daily Value as 44% and 11%, respectively.[28][29]
Phytochemicals
Numerous phytochemicals are present in mango peel and pulp, such as the triterpene,lupeol which is under basic research for its potential biological effects.[30] An extract of mango branch bark called Vimang, containing numerous polyphenols,[31] has been studied in elderly humans.[32]
Mango peel pigments under study includecarotenoids, such as the provitamin Acompound, beta-carotene, lutein and alpha-carotene,[33][34] and polyphenols, such asquercetin, kaempferol, gallic acid, caffeic acid, catechins and tannins.[35][36] Mango contains a unique xanthonoid calledmangiferin.[37]
Phytochemical and nutrient content appears to vary across mango cultivars.[38] Up to 25 different carotenoids have been isolated from mango pulp, the densest of which was beta-carotene, which accounts for the yellow-orange pigmentation of most mango cultivars.[39] Mango leaves also have significant polyphenol content, includingxanthonoids, mangiferin and gallic acid.[40]
The pigment euxanthin, known as Indian yellow, is often thought to be produced from the urine of cattle fed mango leaves; the practice is described as having been outlawed in 1908 because of malnutrition of the cattle and possible urushiol poisoning.[41]This supposed origin of euxanthin appears to rely on a single, anecdotal source, and Indian legal records do not outlaw such a practice.[42]
Flavor
Major flavor chemicals of 'Alphonso' mango from India
The flavor of mango fruits is constituted by several volatile organic chemicals mainly belonging to terpene, furanone, lactone, andester classes. Different varieties or cultivars of mangoes can have flavor made up of different volatile chemicals or same volatile chemicals in different quantities.[43][44] In general, New World mango cultivars are characterized by the dominance of δ-3-carene, a monoterpene flavorant; whereas, high concentration of other monoterpenes such as (Z)-ocimene and myrcene, as well as the presence of lactones and furanones, is the unique feature of Old Worldcultivars.[44][45][46] In India, 'Alphonso' is one of the most popular cultivars. In 'Alphonso' mango, the lactones and furanones are synthesized during ripening; whereas terpenes and the other flavorants are present in both the developing (immature) and ripening fruits.[47][48][49][50] Ethylene, a ripening-related hormone well known to be involved in ripening of mango fruits, causes changes in the flavor composition of mango fruits upon exogenous application, as well.[51][52] In contrast to the huge amount of information available on the chemical composition of mango flavor, the biosynthesis of these chemicals has not been studied in depth; only a handful of genes encoding the enzymes of flavor biosynthetic pathways have been characterized to date.[53][54][55][56]
Potential for contact dermatitis
Contact with oils in mango leaves, stems, sap, and skin can cause dermatitis andanaphylaxis in susceptible individuals.[57]Mango oil contains mangiferin and a resinolcalled mangiferol.[citation needed] Those with a history of contact dermatitis induced byurushiol (an allergen found in poison ivy,poison oak, or poison sumac) may be most at risk for mango contact dermatitis.[58] Cross-reactions may occur between mango allergens and urushiol.[59] During the primary ripening season of mangoes, contact with mango plant parts is the most common cause of plant dermatitis in Hawaii.[60]However, sensitized individuals are still able to safely eat peeled mangos or drink mango juice.[60]
Cultural significance

The mango is the national fruit of India,[61][62]Pakistan, and the Philippines. It is also thenational tree of Bangladesh.[63][64] In India, harvest and sale of mangoes is during March–May and this is annually covered by news agencies. [22]
The Mughal emperor Akbar (1556–1605 AD) is said to have planted a mango orchard having 100,000 trees in Darbhanga, eastern India.[65] The Jain goddess Ambika is traditionally represented as sitting under a mango tree.[66] In Hinduism, the perfectly ripe mango is often held by Lord Ganesha as a symbol of attainment, regarding the devotees' potential perfection. Mango blossoms are also used in the worship of the goddessSaraswati. No Telugu/Kannada New Year's Day called Ugadi passes without eating ugadi pachadi made with mango pieces as one of the ingredients.
Dried mango skin and its seeds are also used in Ayurvedic medicines.[26] Mango leaves are used to decorate archways and doors in Indian houses and during weddings and celebrations such as Ganesh Chaturthi. Mango motifs and paisleys are widely used in different Indian embroidery styles, and are found in Kashmiri shawls, Kanchipuram silksarees, etc. Paisleys are also common to Iranian art, because of its pre-IslamicZoroastrian past.
In Tamil Nadu, the mango is referred to as one of the three royal fruits, along withbanana and jackfruit, for their sweetness and flavor.[67] This triad of fruits is referred to asma-pala-vazhai.
Fruit drinks that include mango are popular in India, with brands such as Frooti, Maaza, andSlice. These leading brands include sugar and artificial flavors, so they do not qualify as "juice" under Food Safety and Standards Authority of India regulations.[68]
In the West Indies, the expression "to go mango walk" means to steal another person's mango fruits. This is celebrated in the famous song, "The Mango Walk".
In Australia, the first tray of mangoes of the season is traditionally sold at an auction for charity.[69]
Mangoes, although they were almost unheard of in China before, were popularized during the Cultural Revolution as symbols ofChairman Mao's love for the people.[71]
