Bananas

Banana is the common name for a fruit and also the herbaceous plants of the genus Musa which produce this commonly eaten fruit. They are native to the tropical region of Southeast Asia. Bananas are likely to have been first domesticated in Papua New Guinea.^[1] Today, they are cultivated throughout the tropics.^[2]

Banana plants are of the family Musaceae. They are cultivated primarily for their fruit, and to a lesser extent for the production of fibre and as ornamental plants. As the banana plants are normally tall and fairly sturdy they are often mistaken for trees, but their main or upright stem is actually a pseudostem (literally "fake stem"). For some species this pseudostem can reach a height of up to 2–8 m, with leaves of up to 3.5 m in length. Each pseudostem can produce a bunch of yellow, green or even red bananas before dying and being replaced by another pseudostem.

The banana fruit grow in hanging clusters, with up to 20 fruit to a tier (called a hand), and 3–20 tiers to a bunch. The total of the hanging clusters is known as a bunch, or commercially as a "banana stem", and can weigh from 30–50 kg. The fruit averages 125 g, of which approximately 75% is water and 25% dry matter content. Each individual fruit (known as a banana or 'finger') has a protective outer layer (a peel or skin) with a fleshy edible inner portion. Both skin and inner part can be eaten raw or cooked. Western cultures generally eat the inside raw and throw away the skin while some Asian cultures generally eat both the skin and inside cooked. Typically, the fruit has numerous strings (called 'phloem bundles') which run between the skin and inner part. Bananas are a valuable source of vitamin B₆, vitamin C, and potassium.

Bananas are grown in at least 107 countries.^[3] In popular culture and commerce, "banana" usually refers to soft, sweet "dessert" bananas. The bananas from a group of cultivars with firmer, starchier fruit are called plantains. Bananas may also be cut and dried and eaten as a type of chip. Dried bananas are also ground into banana flour.

Although the wild species have fruits with numerous large, hard seeds, virtually all culinary bananas have seedless fruits. Bananas are classified either as dessert bananas (meaning they are yellow and fully ripe when eaten) or as green cooking bananas. Almost all export bananas are of the dessert types; however, only about 10–15% of all production is for export, with the United States and European Union being the dominant buyers.

Bananas come in a variety of sizes and colors when ripe, including yellow, purple, and red. Bananas can be eaten raw though some varieties are generally cooked first. Depending upon cultivar and ripeness, the flesh can vary in taste from starchy to sweet, and texture from firm to mushy. Unripe or green bananas and plantains are used for cooking various dishes such as banana pudding and are the staple starch of many tropical populations. Banana sap is extremely sticky and can be used as a practical adhesive. Sap can be obtained from the pseudostem, from the fruit peelings, or from the fruit flesh.

Most production for local sale is of green cooking bananas and plantains, as ripe dessert bananas are easily damaged while being transported to market. Even when transported only within their country of origin, ripe bananas suffer a high rate of damage and loss.^{[citation needed]}

The commercial dessert cultivars most commonly eaten in temperate countries (species Musa acuminata or the hybrid Musa × paradisiaca, a cultigen) are imported in large quantities from the tropics. They are popular in part because, being a non-seasonal crop, they are available fresh year-round. In global commerce, by far the most important of these banana cultivars is 'Cavendish', which accounts for the vast bulk of bananas exported from the tropics. The Cavendish gained popularity in the 1950s after the previously mass produced cultivar, Gros Michel, became commercially unviable due to Panama disease, a fungus which attacks the roots of the banana plant.

The most important properties making 'Cavendish' the main export banana are related to transport and shelf life rather than taste; major commercial cultivars rarely have a superior flavor^{[citation needed]} compared to the less widespread cultivars. Export bananas are picked green, and then usually ripened in ripening rooms when they arrive in their country of destination. These are special rooms made air-tight and filled with ethylene gas to induce ripening. Bananas can be ordered by the retailer "ungassed", however, and may show up at the supermarket still fully green. While these bananas will ripen more slowly, the flavor will be notably richer^{[citation needed]}, and the banana peel can be allowed to reach a yellow/brown speckled phase, and yet retain a firm flesh inside. Thus, shelf life is somewhat extended.

The vivid yellow color normally associated with supermarket bananas is in fact a side-effect of the artificial ripening process. Cavendish bananas that have been allowed to ripen naturally on the plant have a greenish-yellow appearance which changes to a brownish-yellow as they ripen further. Although both the flavor and texture of "tree ripened" bananas is generally regarded as superior to any type green-picked fruit, once natural ripening has commenced the shelf life is typically only 7–10 days, making commercial distribution impractical. For most people the only practical means of obtaining such fruit is growing it themselves, however this is also somewhat problematic, as the bananas all tend to ripen at once and have very poor keeping properties.

The flavor and texture of bananas are also affected by the temperature at which they ripen. Bananas are refrigerated to between 13.5 and 15 °C (57 and 59 °F) during transportation. At lower temperatures, the ripening of bananas permanently stalls, and the bananas will eventually turn gray as cell walls break down. The skins of ripe bananas will quickly turn black in the 4°C environment of a domestic refrigerator, although the fruit inside remains unaffected.

It should be noted that Musa × paradisiaca is also the generic name for the common plantain, a coarser and starchier variant not to be confused with Musa acuminata or the Cavendish variety.

In addition to the fruit, the flower of the banana plant (also known as banana blossom or banana heart) is used in Southeast Asian, Tamil, Bengali, and Kerala (India) cuisine, either served raw with dips or cooked in soups and curries. The tender core of the banana plant's trunk is also used in Bengali and Kerala cooking, and notably in the Burmese dish mohinga. Bananas fried with batter is a popular dessert in Malaysia, Singapore, and Indonesia. Banana fritters can be served with ice cream as well. Bananas are also eaten deep fried, baked in their skin in a split bamboo, or steamed in glutinous rice wrapped in a banana leaf in Burma where bunches of green bananas surrounding a green coconut in a tray form an important part of traditional offerings to the Buddha and the Nats. The juice extract prepared from the tender core is used to treat kidney stones.

The leaves of the banana plant are large, flexible, and waterproof. They are used many ways, including as umbrellas and to wrap food for cooking or storage.^[14] Banana leaves are also used to serve food in India and other Asian countries.

Banana chips are a snack produced from dehydrated or fried banana or plantain slices, which have a dark brown color and an intense banana taste. Bananas have also been used in the making of jam. Unlike other fruits, it is difficult to extract juice from bananas because when compressed a banana simply turns to pulp.

Seeded bananas (Musa balbisiana), the forerunner of the common domesticated banana,^[15] are sold in markets in Indonesia.

In India, juice is extracted from the corm and used as a home remedy for the treatment of jaundice, sometimes with the addition of honey.
