A dessert banana with peel partly removed (partially "peeled"). The peel is the yellow outer "skin".
Discarded banana peels
A banana peel, known as a banana skin in British English, is the outer covering of the banana fruit.
As bananas, whether eaten raw or cooked, are a popular fruit consumed worldwide, with yearly production over 145 million tonnes in 2011, there is a significant amount of banana peel waste being generated as well.
Banana peels are used as feedstock as they have some nutritional value. Banana peels are widely used for that purpose on small farms in regions where bananas are grown. There are some concerns over the impact of tannins contained in the peels on animals that consume them. Banana peels are used as feedstock for cattle, goats, pigs, poultry, rabbits, fish and several other species.
The specific nutrition contained in peel depends on the stage of maturity and the cultivar; for example plantain peels contain less fibre than dessert banana peels, and lignin content increases with ripening (from 7 to 15% dry matter). On average, banana peels contain 6-9% dry matter of protein and 20-30% fibre (measured as NDF). Green plantain peels contain 40% starch that is transformed into sugars after ripening. Green banana peels contain much less starch (about 15%) when green while ripe banana peels contain up to 30% free sugars.
Banana peel is also part of the classic physical comedyslapstickvisual gag, the "slipping on a banana peel". This gag was already seen as classic in 1920s America. It can be traced to the late 19th century, when banana peel waste was considered a public hazard in a number of American towns.
