Bananas possess marked nutritional value. They supply a large quantity of carbohydrates to the human body and an unripe banana has more starch than sugars. The fiber extracted from the pseudostem and peduncle parts of banana plants constitutes cellulose, hemicellulose, pectin and lignin.
The components of banana fruit include moisture, protein, fat, carbohydrates, fiber, ash and minerals like calcium, iron and phosphorus. The fruit is also comprised of vitamins like ascorbic acid, beta carotene, thiamine, niacin and riboflavin. The fat and protein contents of bananas are lower compared to the levels of carbohydrates and some minerals like phosphorus and calcium. The percentage of the chemical components differ in various cultivars of bananas.
