|Coconut palm (Cocos nucifera)|
The coconut tree (Cocos nucifera) is a member of the palm tree family (Arecaceae) and the only living species of the genus Cocos. The term "coconut" (or the archaic "cocoanut") can refer to the whole coconut palm, the seed, or the fruit, which botanically is a drupe, not a nut. The term is derived from the 16th-century Portuguese and Spanish word coco meaning "head" or "skull" after the three indentations on the coconut shell that resemble facial features.
Coconuts are known for their versatility of uses, ranging from food to cosmetics. The inner flesh of the mature seed forms a regular part of the diets of many people in the tropics and subtropics. Coconuts are distinct from other fruits because their endosperm contains a large quantity of clear liquid, called "coconut milk" in the literature, and when immature, may be harvested for their potable "coconut water", also called "coconut juice".
Mature, ripe coconuts can be used as edible seeds, or processed for oil and plant milk from the flesh, charcoal from the hard shell, and coir from the fibrous husk. Dried coconut flesh is called copra, and the oil and milk derived from it are commonly used in cooking – frying in particular – as well as in soaps and cosmetics. The hard shells, fibrous husks and long pinnate leaves can be used as material to make a variety of products for furnishing and decorating. The coconut also has cultural and religious significance in certain societies, particularly in India, where it is used in Hindu rituals.

The name coconut derives from seafarers during the 16th and 17th century for its resemblance to a head. 'Coco' and 'coconut' apparently came from 1521 encounters by Portuguese and Spanish explorers with Pacific islanders, with the coconut shell reminding them of a ghost or witch in Portuguese folklore called coco (also côca).
One of the earliest mentions of the coconut dates back to the "One Thousand and One Nights" story of Sinbad the Sailor; he is known to have bought and sold coconut during his fifth voyage. Thenga, its Malayalam name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it jawz hindī, translating to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written around 545, there is a reference to the argell tree and its drupe.
In March 1521, a description of the coconut was given by Antonio Pigafetta writing in Italian and using the words "cocho"/"cochi", as recorded in his journal after the first European crossing of the Pacific Ocean during the Magellan circumnavigation and meeting the inhabitants of what would become known as Guam and the Philippines. He explained how at Guam "they eat coconuts" ("mangiano cochi") and that the natives there also "anoint the body and the hair with coconut and beniseed oil" ("ongieno el corpo et li capili co oleo de cocho et de giongioli").
The origin of the plant is, after many decades, still the subject of debate. It has generally been accepted that the coconut originated in the India–Indonesia region and float-distributed itself around the world by riding ocean currents. The similarities of the local names in the Malaysia–Indonesia region is also cited as evidence that the plant originated in the region. For example, the Polynesian and Melanesian term niu and the Tagalog and Chamorro term niyog is said to be based on the Malay word nyiur or nyior.
O. F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on his belief that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this as one part of his hypothesis to support his theory that the Pacific Islanders originated as two migration streams from the Canadian Pacific coast (themselves recent migrants from Asia) to Hawaii, and on to Tahiti and New Zealand in a series of hops, and another migration from South America via sailing balsa-wood rafts.
The oldest fossils known of the modern coconut dating from the Eocene period from around 55 million to 37 million years ago were found in Australia and India, but older palm fossils such as some of nipa fruit have been found in the Americas. A partial well preserved and detailed fossil palm frond of †Cocos robustifolia from the lower Oligocene has been described from a collection made from 1857 to 1889 in Santa Giustina and Sassello in Central Liguria, Italy. A species with strawberry-sized nuts (Cocos zeylanica) lived in New Zealand in the Miocene. Since 1978, the work on tracing the probable origin and dispersal of Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem — without human intervention — and required a thick husk and slow germination to survive and disperse.
Cocos nucifera is a large palm, growing up to 30 m (98 ft) tall, with pinnate leaves 4–6 m (13–20 ft) long, and pinnae 60–90 cm (2–3 ft) long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On fertile soil, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 to 20 years to reach peak production.
The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconuts. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (micropyles) or "eyes" that are clearly visible on its outside surface once the husk is removed.
The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. This type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.
Coconut palms continue to produce roots from the base of the stem throughout their lives. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that is 60 to 70 years old.
Roots are usually less than about 75 mm (3 inches) in diameter and uniformly thick from the tree trunk to the root tip.
The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some[which?] dwarf varieties are self-pollinating.
Coconuts could not reach inland locations without human intervention (to carry seednuts, plant seedlings, etc.) and early germination on the palm (vivipary) was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid "meat" or liquid "water" that provides the fruit its food value. Although these modifications for domestication would reduce the fruit's ability to float, this ability would be irrelevant to a cultivated population.
Among modern C. nucifera, two major types or variants occur: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera. The first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm-to-husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, thus creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries' adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.
Variants of C. nucifera are also categorized as tall (var. typica) or dwarf (var. nana). The two groups are genetically distinct, with the dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The tall variety is outcrossing while dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the tall group. The dwarf subspecies is thought to have mutated from the tall group under human selection pressure.

It is often stated that coconuts can travel 110 days, or 3,000 miles (4,800 km), by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size that forms the basis of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki:
"The nuts we had in baskets on deck remained edible and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it."
He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, the coconut variety Heyerdahl chose for his long sea voyage likely was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore, Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.
Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. If they were naturally distributed and had been in the Pacific for a thousand years or so, then we would expect the eastern shore of Australia, with its own islands sheltered by the Great Barrier Reef, to have been thick with coconut palms: the currents were directly into, and down along this coast. However, both James Cook and William Bligh (put adrift after the Bounty mutiny) found no sign of the nuts along this 2,000 km (1,200 mi) stretch when he needed water for his crew. Nor were there coconuts on the east side of the African coast until Vasco da Gama, nor in the Caribbean when first visited by Christopher Columbus. They were commonly carried by Spanish ships as a source of sweet water.
This provides substantial circumstantial evidence that deliberate voyagers were involved in carrying coconuts across the Pacific Ocean (possibly the Austronesian peoples) and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (C. nucifera L.) has shed light on the movement. However, admixture, the transfer of genetic material, evidently occurred between the two populations.
Given that coconuts are ideally suited for inter-island group ocean dispersal, obviously some natural distribution did take place. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut. This, together with their use of the South American sweet potato, suggests that Austronesian peoples may have sailed as far east as the Americas.
The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant, and highly water resistant. It is claimed that they evolved to disperse significant distances via marine currents. However, it can also be argued that the placement of the vulnerable eye of the nut (down when floating), and the site of the coir cushion are better positioned to ensure that the water-filled nut does not fracture when dropping on rocky ground, rather than for flotation.
Specimens have been collected from the sea as far north as Norway (but it is not known where they entered the water). In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years (the Caribbean native inhabitants do not have a dialect term for them, but use the Portuguese name), but evidence of their presence on the Pacific coast of South America antedates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26° N and 26° S except for the interiors of Africa and South America.
The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1,500–2,500 mm [59–98 in] annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (at least 70–80%) for optimum growth, which is why they are rarely seen in areas with low humidity. However, they can be found in humid areas with low annual precipitation such as in Karachi, Pakistan, which receives only about 250 mm (9.8 in) of rainfall per year, but is consistently warm and humid.
Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C (82 and 99 °F), and survival as long as winter temperatures are above 4–12 °C (39–54 °F); they will survive brief drops to 0 °C (32 °F). Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C (25 °F). They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.
The conditions required for coconut trees to grow without any care are:
- Mean daily temperature above 12–13 °C (54–55 °F) every day of the year
- Mean annual rainfall above 1,000 mm (39 in)
- No or very little overhead canopy, since even small trees require direct sun
The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.
Coconuts are susceptible to the phytoplasma disease, lethal yellowing. One recently selected cultivar, the 'Maypan', has been bred for resistance to this disease. Yellowing diseases affect plantations in Africa, India, Mexico, the Caribbean and the Pacific Region.
The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including the African armyworm (Spodoptera exempta) and Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.
Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages both seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the Philippine coconut industry managed by some 3.5 million farmers.
The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating; it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with Neem-based pesticides can give some relief, but is cumbersome and labor-intensive.
In Kerala, India, the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil, and the coconut leaf caterpillar. Research into countermeasures to these pests has as of 2009[update] yielded no results; researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode, continue to work on countermeasures. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called the compact area group approach to combat coconut mites.
Production and cultivation
|Coconut production, 2016
(millions of tonnes)
Coconut palms are grown in more than 90 countries and territories of the world, with a total production of over 59 million tonnes in 2016 (table). Most of the world production is in tropical Asia, with Indonesia, the Philippines, and India collectively accounting for over 72% of the world total (table).
Coconut palms are normally cultivated in hot and wet tropical climates. They need year round warmth and moisture to grow well and fruit. Coconut palms are hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.
In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Thailand has been raising and training pig-tailed macaques to pick coconuts for around 400 years.
Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Puducherry, Andhra Pradesh, Goa, Maharashtra, Odisha, West Bengal and, Gujarat and the islands of Lakshadweep and Andaman and Nicobar. As per 2014–15 statistics from Coconut Development Board of Government of India, four southern states combined account for almost 90% of the total production in the country: Tamil Nadu (33.84%), Karnataka (25.15%), Kerala (23.96%), and Andhra Pradesh (7.16%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining productions. Though Kerala has the largest number of coconut trees, in terms of production per hectare, Tamil Nadu leads all other states. In Tamil Nadu, Coimbatore and Tirupur regions top the production list.
In Goa, the coconut tree has been reclassified by the government as a palm (like a grass), enabling farmers and real estate developers to clear land with fewer restrictions. With this, it will no more be considered as a tree and no permission will be required by the forest department before cutting a coconut tree.
The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem and coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.
The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea, and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa, and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional seagoing dhow vessels in which nails were never used. The knowhow of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.
The coconut cultivars grown in Oman are generally of the drought-resistant Indian 'West Coast tall' variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.
The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla. The annual rainy season known locally as khareef or monsoon makes coconut cultivation easy on the Arabian east coast.
Coconut trees also are increasingly grown for decorative purposes along the coasts of the United Arab Emirates and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary lifestyles and heavy-handed landscaping, a decline in these traditional farming and soil-fixing techniques has occurred.
In the United States, coconut palms can be grown and reproduced outdoors without irrigation in Hawaii, southern and central Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.
In Florida, wild populations of coconut palms extend up the East Coast from Key West to Jupiter Inlet, and up the West Coast from Marco Island to Sarasota. Many of the smallest coral islands in the Florida Keys are known to have abundant coconut palms sprouting from coconuts that have drifted or been deposited by ocean currents. Coconut palms are cultivated north of south Florida to roughly Cocoa Beach on the East Coast and the St/Petersburg on the West Coast.
Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.
The 1889 book 'The Useful Native Plants of Australia records that the Cocus nucifera "nut is so well known that the following few notes concerning it will be sufficient. As an article of food the kernel is of great importance to the inhabitants of the tropics. In the Laccadives it forms the chief food, each person consuming four nuts per day, and the fluid, commonly called milk, which it contains, affords them an agreeable beverage. While young they yield a delicious substance resembling blancmange. Among other products of this palm may be mentioned " toddy," which when fermented is intoxicating ; strong arrack is also distilled from it, besides which it yields vinegar and "jaggery" or sugar."

Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited; therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.
In the winter, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1 1⁄2 to 3 feet [46 to 91 cm]) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rainwater quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as few as one or two mature fruits), as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.
Conversely, trees growing in close proximity to the sea almost universally yield much more fruit, as they are able to tap directly into the seawater which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success, as they are also able to tap directly into a constant supply of water.
Substitutes for cooler climates
In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are similar to the coconut, but smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C (64 °F) and need a daily temperature above 22 °C (72 °F) to produce fruit.
The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".
The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut, but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite. Shredded or flaked coconut is used as a garnish on some foods. Some countries in Southeast Asia use special coconut mutant called Kopyor coconut (Kopyor in Indonesia) or macapuno (in the Philippines) as dessert drinks.

Per 100-gram serving with 354 calories, raw coconut meat supplies a high amount of total fat (33 grams), especially saturated fat (89% of total fat), moderate content of carbohydrates (15 grams), and protein (3 grams). Micronutrients in significant content (more than 10% of the Daily Value) include the dietary minerals, manganese, copper, iron, phosphorus, selenium, and zinc (table).
Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. It is consumed throughout the humid tropics, and has been introduced into the retail market as a processed sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.
Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a total fat content of 24%, most of which (89%) is saturated fat, with lauric acid as a major fatty acid. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.
Another product of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.
Toddy and nectar
The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".
The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 litres (66 imp gal; 79 US gal) of toddy per year, while a 40-year-old tree may yield around 400 litres (88 imp gal; 110 US gal).
Heart of palm and coconut sprout
Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo. Coconut haustorium, a spongy absorbent tissue formed from the distal portion of embryo during coconut germination, facilitates absorption of nutrients for the growing shoot and root.
Coconut is an indispensable ingredient in Indonesian cuisine. Coconut meat, coconut milk, and coconut water are often used in main courses, desserts, and soups throughout the archipelago. On the island of Sumatra, the famous rendang, the traditional beef stew from West Sumatra, chunks of beef are cooked in coconut milk along with other spices for hours until thickened. In Jakarta, soto babat or beef tripe soup also uses coconut milk. On the island of Java, the sweet and savoury tempe bacem is made by cooking tempeh with coconut water, coconut sugar, and other spices until thickened. Klapertart is the famous Dutch-influenced dessert from Manado, North Sulawesi, that uses young coconut meat and coconut milk.
In 2010, Indonesia increased its coconut production. It is now the world's largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear, as well as on the scouting pins and flags.
The Philippines is the world's second-largest producer of coconuts; the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments, and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsî, palitaw and buko pie. Coconut jam is made by mixing muscovado with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands, and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product—nata de coco (coconut gel).
In Vietnam, coconut is grown abundantly across central and southern Vietnam, and especially in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho, chè, and curry (cà ri).
In southern India, the most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also a main side dish served with idli, vadai, and dosai. Coconut ground with spices is mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Solkadhi, a drink made from coconut milk and kokum, is usually consumed after meals. Narali paak is another sweet dish, created with coconut and sugar. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka, sweets are prepared using coconut and dry coconut copra.
Commercial, industrial, and household use
Coconut has a number of commercial and traditional cultivars. They can be sorted mainly into tall cultivars, dwarf cultivars, and hybrid cultivars (hybrids between talls and dwarfs). Some of the dwarf cultivars such as 'Malayan dwarf' have shown some promising resistance to lethal yellowing, while other cultivars such as 'Jamaican tall' are highly affected by the same plant disease. Some cultivars are more drought resistant such as 'West coast tall' (India) while others such as 'Hainan Tall' (China) are more cold tolerant. Other aspects such as seed size, shape and weight, and copra thickness are also important factors in the selection of new cultivars. Some cultivars such as 'Fiji dwarf' form a large bulb at the lower stem and others are cultivated to produce very sweet coconut water with orange-coloured husks (king coconut) used entirely in fruit stalls for drinking (Sri Lanka, India).
Coir (the fiber from the husk of the coconut) is used in ropes, mats, doormats, brushes, and sacks, as caulking for boats, and as stuffing fiber for mattresses. It is used in horticulture in potting compost, especially in orchid mix.
The stiff midribs of coconut leaves are used for making brooms in India, Indonesia (sapu lidi), Malaysia, the Maldives, and the Philippines (walis tingting). The green of the leaves (lamina) is stripped away, leaving the veins (long, thin, woodlike strips) which are tied together to form a broom or brush. A long handle made from some other wood may be inserted into the base of the bundle and used as a two-handed broom. The leaves also provide material for baskets that can draw well water and for roofing thatch; they can be woven into mats, cooking skewers, and kindling arrows as well. Two leaves (especially the younger, yellowish shoots) woven into a tight shell the size of the palm are filled with rice and cooked to make ketupat. Dried coconut leaves can be burned to ash, which can be harvested for lime. In India, the woven coconut leaves are used as pandals (temporary sheds) for marriage functions especially in the states of Kerala, Karnataka, and Tamil Nadu.
Copra is the dried meat of the seed and after processing produces coconut oil and coconut meal. Coconut oil, aside from being used in cooking as an ingredient and for frying, is used in soaps, cosmetics, hair oil, and massage oil. Coconut oil is also a main ingredient in Ayurvedic oils. In Vanuatu, coconut palms for copra production are generally spaced 9 m (30 ft) apart, allowing a tree density of 100 to 160 per hectare (40 to 65 per acre).
Husks and shells
The husk and shells can be used for fuel and are a source of charcoal. Activated carbon manufactured from coconut shell is considered extremely effective for the removal of impurities. The coconut's obscure origin in foreign lands led to the notion of using cups made from the shell to neutralise poisoned drinks. The cups were frequently engraved and decorated with precious metals.
A dried half coconut shell with husk can be used to buff floors. It is known as a bunot in the Philippines and simply a "coconut brush" in Jamaica. The fresh husk of a brown coconut may serve as a dish sponge or body sponge. A coco chocolatero was a cup used to serve small quantities of beverages (such as chocolate drinks) between the 17th and 19th centuries in countries such as Mexico, Guatemala, and Venezuela.
In Asia, coconut shells are also used as bowls and in the manufacture of various handicrafts, including buttons carved from dried shell. Coconut buttons are often used for Hawaiian aloha shirts. Tempurung, as the shell is called in the Malay language, can be used as a soup bowl and—if fixed with a handle—a ladle. In Thailand, the coconut husk is used as a potting medium to produce healthy forest tree saplings. The process of husk extraction from the coir bypasses the retting process, using a custom-built coconut husk extractor designed by ASEAN–Canada Forest Tree Seed Centre in 1986. Fresh husks contain more tannin than old husks. Tannin produces negative effects on sapling growth. In parts of South India, the shell and husk are burned for smoke to repel mosquitoes.
Half coconut shells are used in theatre Foley sound effects work, struck together to create the sound effect of a horse's hoofbeats. Dried half shells are used as the bodies of musical instruments, including the Chinese yehu and banhu, along with the Vietnamese đàn gáo and Arabo-Turkic rebab. In the Philippines, dried half shells are also used as a music instrument in a folk dance called maglalatik.
In World War II, coastwatcher scout Biuku Gasa was the first of two from the Solomon Islands to reach the shipwrecked and wounded crew of Motor Torpedo Boat PT-109 commanded by future U.S. president John F. Kennedy. Gasa suggested, for lack of paper, delivering by dugout canoe a message inscribed on a husked coconut shell, reading “Nauru Isl commander / native knows posit / he can pilot / 11 alive need small boat / Kennedy.” This coconut was later kept on the president's desk, and is now in the John F. Kennedy Library.
Coconut trunks are used for building small bridges and huts; they are preferred for their straightness, strength, and salt resistance. In Kerala, coconut trunks are used for house construction. Coconut timber comes from the trunk, and is increasingly being used as an ecologically sound substitute for endangered hardwoods. It has applications in furniture and specialized construction, as notably demonstrated in Manila's Coconut Palace.
Hawaiians hollowed the trunk to form drums, containers, or small canoes. The "branches" (leaf petioles) are strong and flexible enough to make a switch. The use of coconut branches in corporal punishment was revived in the Gilbertese community on Choiseul in the Solomon Islands in 2005.

In the Ilocos region of the northern Philippines, the Ilocano people fill two halved coconut shells with diket (cooked sweet rice), and place liningta nga itlog (halved boiled egg) on top of it. This ritual, known as niniyogan, is an offering made to the deceased and one's ancestors. This accompanies the palagip (prayer to the dead).
A coconut (Sanskrit: nalikera) is an essential element of rituals in Hindu tradition. Often it is decorated with bright metal foils and other symbols of auspiciousness. It is offered during worship to a Hindu god or goddess. Narali Purnima is celebrated on a full moon day which usually signifies the end of monsoon season in India. The word ‘Narali’ is derived from naral implying ‘coconut’ in Marathi. Fishermen give an offering of coconut to the sea to celebrate the beginning of a new fishing season. Irrespective of their religious affiliations, fishermen of India often offer it to the rivers and seas in the hopes of having bountiful catches. Hindus often initiate the beginning of any new activity by breaking a coconut to ensure the blessings of the gods and successful completion of the activity. The Hindu goddess of well-being and wealth, Lakshmi, is often shown holding a coconut. In the foothills of the temple town of Palani, before going to worship Murugan for the Ganesha, coconuts are broken at a place marked for the purpose. Every day, thousands of coconuts are broken, and some devotees break as many as 108 coconuts at a time as per the prayer.
In Hindu wedding ceremonies, a coconut is placed over the opening of a pot, representing a womb. Coconut flowers are auspicious symbols and are fixtures at Hindu and Buddhist weddings and other important occasions. In Kerala, coconut flowers must be present during a marriage ceremony. The flowers are inserted into a barrel of unhusked rice (paddy) and placed within sight of the wedding ceremony. Similarly in Sri Lanka, coconut flowers, standing in brass urns, are placed in prominent positions.
The Zulu Social Aid and Pleasure Club of New Orleans traditionally throws hand-decorated coconuts, the most valuable of Mardi Gras souvenirs, to parade revelers. The "Tramps" began the tradition circa 1901. In 1987, a "coconut law" was signed by Governor Edwin Edwards exempting from insurance liability any decorated coconut "handed" from a Zulu float.
The coconut is also used as a target and prize in the traditional British fairground game "coconut shy". The player buys some small balls which he throws as hard as he can at coconuts balanced on sticks. The aim is to knock a coconut off the stand and win it.
Myths and legends
Some South Asian, Southeast Asian, and Pacific Ocean cultures have origin myths in which the coconut plays the main role. In the Hainuwele myth from Maluku, a girl emerges from the blossom of a coconut tree. In Maldivian folklore, one of the main myths of origin reflects the dependence of the Maldivians on the coconut tree.
According to an urban legend, more deaths are caused by falling coconuts than by sharks annually.
The leftover fiber from coconut oil and coconut milk production, coconut meal, is used as livestock feed. The dried calyx is used as fuel in wood-fired stoves. Coconut water is traditionally used as a growth supplement in plant tissue culture and micropropagation. The smell of coconuts comes from the 6-pentyloxan-2-one molecule, known as δ-decalactone in the food and fragrance industries.
Tool and shelter for animals
Researchers from the Melbourne Museum in Australia observed the octopus species Amphioctopus marginatus use tools, specifically coconut shells, for defense and shelter. The discovery of this behavior was observed in Bali and North Sulawesi in Indonesia between 1998 and 2008. Amphioctopus marginatus is the first invertebrate known to be able to use tools.
A coconut can be hollowed out and used as a home for a rodent or small birds. Halved, drained coconuts can also be hung up as bird feeders, and after the flesh has gone, can be filled with fat in winter to attract tits.
Cocamidopropyl betaine (CAPB) is a surfactant manufactured from coconut oil that is increasingly used as an ingredient in personal hygiene products and cosmetics, such as shampoos, liquid soaps, cleansers and antiseptics, among others. CAPB may cause mild skin irritation, but allergic reactions to CAPB are rare and probably related to impurities rendered during the manufacturing process (which include amidoamine and dimethylaminopropylamine) rather than CAPB itself.
Many varieties of coconuts C. nucifera are being cultivated in many countries. These vary by the taste of the coconut water and color of the fruit, as well as other genetic factors.
