banana use as fast food in the world

Bananas are a staple starch for many tropical populations. Depending upon cultivar and ripeness, the flesh can vary in taste from starchy to sweet, and texture from firm to mushy. Both the skin and inner part can be eaten raw or cooked. The primary component of the aroma of fresh bananas is isoamyl acetate (also known as banana oil), which, along with several other compounds such as butyl acetate and isobutyl acetate, is a significant contributor to banana flavor.[91][92][93]
During the ripening process, bananas produce the gas ethylene, which acts as a plant hormone and indirectly affects the flavor. Among other things, ethylene stimulates the formation of amylase, an enzyme that breaks down starch into sugar, influencing the taste of bananas. The greener, less ripe bananas contain higher levels of starch and, consequently, have a "starchier" taste. On the other hand, yellow bananas taste sweeter due to higher sugar concentrations. Furthermore, ethylene signals the production of pectinase, an enzyme which breaks down the pectinbetween the cells of the banana, causing the banana to soften as it ripens.[94][95]
Bananas are eaten deep fried, baked in their skin in a split bamboo, or steamed in glutinous rice wrapped in a banana leaf. Bananas can be made into jam. Banana pancakes are popular amongst backpackers and other travelers in South Asia and Southeast Asia. This has elicited the expression Banana Pancake Trail for those places in Asia that cater to this group of travelers. Banana chips are a snack produced from sliced dehydrated or fried banana or plantain, which have a dark brown color and an intense banana taste. Dried bananas are also ground to make banana flour. Extracting juice is difficult, because when a banana is compressed, it simply turns to pulp. Bananas feature prominently in Philippine cuisine, being part of traditional dishes and desserts like maruyaturón, and halo-halo or saba con yelo. Most of these dishes use the Saba or Cardaba banana cultivar. Bananas are also commonly used in cuisine in the South-Indian state of Kerala, where they are steamed (puzhungiyathu), made into curries,[96] fried into chips (upperi)[97] or fried in batter (pazhampori).[98] Pisang goreng, bananas fried with batter similar to the Filipinomaruya or Kerala pazhampori, is a popular dessert in MalaysiaSingapore, and Indonesia. A similar dish is known in the United Kingdom and United States as banana fritters.
Plantains are used in various stews and curries or cooked, baked or mashed in much the same way as potatoes, such as the Pazham Pachadi prepared inKerala.[96]
Seeded bananas (Musa balbisiana), one of the forerunners of the common domesticated banana,[99] are sold in markets in Indonesia

afrika bananas

East Africa

Most farms supply local consumption. Cooking bananas represent a major food source and a major income source for smallhold farmers. In east Africa, highland bananas are of greatest importance as a staple food crop. In countries such as UgandaBurundi, and Rwanda per capita consumption has been estimated at 45 kilograms (99 lb) per year, the highest in the world.[citation needed]

Modern cultivation

All widely cultivated bananas today descend from the two wild bananas Musa acuminata and Musa balbisiana. While the original wild bananas contained large seeds, diploid or polyploid cultivars (some being hybrids) with tiny seeds are preferred for human raw fruit consumption.[61] These are propagated asexually from offshoots. The plant is allowed to produce two shoots at a time; a larger one for immediate fruiting and a smaller "sucker" or "follower" to produce fruit in 6–8 months. The life of a banana plantation is 25 years or longer, during which time the individual stools or planting sites may move slightly from their original positions as lateral rhizome formation dictates.[citation needed]
Cultivated bananas are parthenocarpic, i.e. the flesh of the fruit swells and ripens without its seeds being fertilized and developing. Lacking viable seeds, propagation typically involves farmers removing and transplanting part of the underground stem (called a corm). Usually this is done by carefully removing a sucker (a vertical shoot that develops from the base of the banana pseudostem) with some roots intact. However, small sympodial corms, representing not yet elongated suckers, are easier to transplant and can be left out of the ground for up to two weeks; they require minimal care and can be shipped in bulk.[citation needed]
It is not necessary to include the corm or root structure to propagate bananas; severed suckers without root material can be propagated in damp sand, although this takes somewhat longer.[citation needed]
In some countries, commercial propagation occurs by means of tissue culture. This method is preferred since it ensures disease-free planting material. When using vegetative parts such as suckers for propagation, there is a risk of transmitting diseases (especially the devastating Panama disease).[citation needed]
As a non-seasonal crop, bananas are available fresh year-round.[citation needed]
