Banana

Description
Bananas are the most popular fresh fruit in the United States. They have a peel that comes off easily, they ripen after they've been picked, there is a generous supply all year, and they are inexpensive. Bananas have both a high amount of carbohydrates as well as potassium, which also makes them the fruit of choice for many athletes. (Wellness Encyclopedia of Food and Nutrition, 1992).

A banana plant is a herb in the genus, Musa, which because of its size and structure, is often mistaken for a tree. It is cultivated for its fruit, which also bears the same name. Bananas are of the Family Musaceae and closely related to plantains. Globally, bananas rank fourth after rice, wheat and maize in human consumption; they are grown in 130 countries worldwide, more than for any other fruit crop. Bananas are native to tropical southeastern Asia.

The main or upright growth is called a pseudostem, which when mature will obtain a height of 2–8 m (varies by cultivar), with leaves of up to 3.5 m in length. Each pseudostem produces a single bunch of bananas, before dying and being replaced by a new pseudostem. The base of the plant is a rhizome (known as a corm). Corms are perennial, with a productive lifespan of 15 years or more.

The term banana is applied to both the plant and its elongated fruit (technically a false berry) which grow in hanging clusters, with up to 20 fruit to a tier (called a hand), and 5-20 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 125g, of which approximately 75% is water and 25% dry matter content. Bananas are a valuable source of Vitamin A, Vitamin C, and potassium.

In 2003, India led the world in banana production, representing approximately 23% of the worldwide crop, most of which was for domestic consumption. The four leading banana exporter countries were Ecuador, Costa Rica, Philippines, and Colombia; accounted for about two thirds of the worlds exports; with each exporting more than 1 million tons. Ecuador alone provided more than 30% of global banana exports according to FAO statistics.

Bananas are classified either as dessert bananas (meaning they are yellow and fully ripe when eaten) or as green cooking bananas/plantains. Almost all export bananas are of the dessert variety; however, only about 10-15% of all production is for export, with the U.S. and EU being the dominant buyers.

Bananas and plantains constitute a major staple food crop for millions of people in developing countries. In most tropical countries green (unripe) bananas used for cooking represent the main cultivars. Cooking bananas are very similar to potatoes in how they are used. Both can be fried, boiled, baked or chipped and have similar taste and texture when served. Nutritionally one green cooking banana has about the same nutritional and calorie content as one potato.

The vast majority of producers are small-scale farmers growing the crop either for home consumption or for local markets. Because bananas and plantains will produce fruit year-round, they provide an extremely valuable source of food during the hunger season (that period of time when all the food from the previous harvest has been consumed, and the next harvest is still some time away). It is for these reasons that bananas and plantains are of major importance to food security.

Selection
Avoid bananas with brown spots that seem very soft. Select those bananas with a nice color, specific for the variety. Choose fruit that is firm and free of bruises. Best eating quality has been reached when the solid yellow skin color is speckled with brown. Bananas with green tips or with practically no yellow color have not developed their full flavor. Bananas are overripe when they have a strong odor.

Storage
To further ripen bananas leave at room temperature for a couple of days. Once ripe you can store in the refrigerator for 3 to 5 days. The peel may turn brown in the refrigerator, but the fruit will not change.

Varieties
The very popular yellow banana of Cavendish is the banana we see in grocery stores. However, Plantains, Finger Bananas and Red Bananas are also popular varieties. Most have a soft texture when ripe.
