Anacardium occidentale, Linn. Cashew. Fig. 192. A large, spreading tree with milky juice, very impatient of frost, and therefore adaptable only to extreme S. Fla. in the U. S. : Lvs. oval or obovate, rounded, or even emarginate at the top : fls. rosy- tinted, fragrant, in clusters terminating the young branches: nut kidney-shaped or heart- shaped, the size of a large bean, the kernel edible. This nut (about 1 in. long) is borne on a fleshy receptacle (the cashew apple. Fig. 33) which is about 3 in. high when mature, white to yellow and red, and is sweetish-sour and edible. Gn. 11, p. 211.— A vinous liquor is made from the apple. The kernel of the nut yields oil, and is edible when roasted; the shell of the nut is exceedingly acrid, even the fumes from the roasting being highly irritant. The tree yields a gum which is the basis of a varnish, being used to protect books and woodwork from the ravages of white ante and other insects. The tree grows 20-40 ft. high. Sometimes grown under glass in collections of economic plants; prop, then by cuttings of mature wood with Lvs. retained.

The '''Cashew''' (''Anacardium occidentale''; [[syn.]] ''Anacardium curatellifolium'' [[A.St.-Hil.]]) is a [[tree]] in the [[flowering plant]] family [[Anacardiaceae]]. The [[plant]] is native to northeastern [[Brazil]], where it is called by its [[Portuguese language|Portuguese]] name ''Caju'' (the fruit) or ''Cajueiro'' (the tree). It is now widely grown in [[tropics|tropical]] [[climate]]s for its cashew "nuts" (see below) and cashew apples.

Cashew is produced in around 32 countries of the world. The world production figures of cashew crop is around 22.5 hundred thousand tons per annum. The major raw cashew producing countries with their production figures in 2005 are Vietnam (8,27,000 tons), India (4,60,000 tons), Brazil (2,51,268 tons) and Nigeria (2,13,000 tons).

World’s total area under the cultivation of cashew is around 35.1 hundred thousand hectares, India again being at the top in list of the countries regarding the maximum area utilized in cashew production. It is considered to be a high ratio of area as compared to the yield of the crop due to low productivity. The world’s average yield is 700 pounds per acre of land.

The major trading centers of cashew in India are Palasa, Kollam, Mangalore, Quilon and Kochi.

The cashew apple is used for its juicy but acidic pulp, which can be eaten raw or used in the production of [[jam]], [[chutney]], or various beverages. Depending on local customs, its juice is also processed and distilled into [[liquor]] or consumed diluted and sugared as a refreshing drink, [[Cajuína]]. Ripe cashew apples also make good [[caipirinha]]. In [[Goa]], India, the cashew apple is the source of juicy pulp used to prepare ''[[fenny]]'', a locally popular distilled liquor. The cashew apple contains much [[tannin]] and is very perishable. For this reason, in many parts of the world, the false fruit is simply discarded after removal of the cashew nut.

The urushiol must be removed from the dark green nut shells before the seed inside is processed for consumption; this is done by shelling the nuts, a somewhat hazardous process, and exceedingly painful skin rashes (similar to poison-ivy rashes) among processing workers are common. In India urushiol is traditionally used to control tamed elephants by its [[mahout]] (rider or keeper). The so-called &quot;raw cashews&quot; available in health food shops have been cooked but not roasted or browned.

Cashew nuts are a common ingredient in [[Asian cuisine|Asian cooking]]. They can also be ground into a spread called cashew butter similar to [[peanut butter]]. Cashews have a very high [[Vegetable oil|oil]] content, and they are used in some other nut butters to add extra oil. In an off-the-shelf package of cashews found in the [[United States]], a 30-gram serving contained 180 calories (750 kilojoules), 70% of which was fat.

The liquid contained within the shell casing of the cashew, known as Cashew Nut Shell Liquid (CNSL), has a variety of industrial uses which were first developed in the [[1930s]]. CNSL is fractionated in a process similar to the distillation of [[petroleum]], and has two primary end products: solids that are pulverized and used as friction particle for brake linings, and an amber-colored liquid that is [[amine|aminated]] to create [[phenalkamine]] curing agents and resin modifiers. Phenalkamines are primarily used in [[epoxy]] coatings for the marine and flooring markets, as they have intense hydrophobic properties and are capable of remaining chemically active at low temperatures.

The Cashew (Anacardium occidentale; syn. Anacardium curatellifolium A.St.-Hil.) is a tree in the flowering plant family Anacardiaceae. The plant is native to northeastern Brazil, where it is called by its Portuguese name Caju (the fruit) or Cajueiro (the tree). It is now widely grown in tropical climates for its cashew "nuts" (see below) and cashew apples.

'Anacardium occidentale', from Koehler's 'Medicinal-Plants' (1887)
Tree shape

It is a small evergreen tree growing to 10-12 m tall, with a short, often irregularly-shaped trunk. The leaves are spirally arranged, leathery textured, elliptic to obovate, 4-22 cm long and 2-15 cm broad, with a smooth margin. The flowers are produced in a panicle or corymb up to 26 cm long, each flower small, pale green at first then turning reddish, with five slender, acute petals 7-15 mm long.

What appears to be the fruit of the cashew tree is an oval or pear-shaped accessory fruit or false fruit that develops from the receptacle of the cashew flower. Called the cashew apple, better known in Central America as "marañón", it ripens into a yellow and/or red structure about 5–11 cm long.

The true fruit of the cashew tree is a kidney or boxing-glove shaped drupe that grows at the end of the pseudofruit. Actually, the drupe develops first on the tree, and then the peduncle expands into the pseudofruit. Within the true fruit is a single seed, the cashew nut. Although a nut in the culinary sense, in the botanical sense the fruit of the cashew is a seed. However, the true fruit is classified as a nut by some botanists. The seed is surrounded by a double shell containing a caustic phenolic resin, urushiol, a potent skin irritant toxin (also found in the related poison-ivy). Some people are allergic to cashews, but cashews are a less frequent allergen than some other nuts.

Other vernacular names include cajueiro, cashu, casho, acajuiba, caju, acajou, acaju, acajaiba, alcayoiba, anacarde, anacardier, anacardo, cacajuil, cajou, gajus, jocote maranon, maranon, merey, noix d’acajou, pomme cajou, pomme, jambu, jambu golok, jambu mete, jambu monyet, jambu terong, kasoy. In the Antilles, specifically Puerto Rico, it is known as pajuil and the pseudofruit is the main used part as raw fruit.


Read about Cashew in the Standard Cyclopedia of Horticulture
