Composition of banana peel.

                     

Banana peel is the outer covering of banana .Peels form 18-30%of the total fruit and are a waste product.Peels are good sources of cartenoids ,polyphenols and certain bio active compounds which impart beneficial effects on human health. On average banana peels contain 6-9% dry matter of protein and 20-30% fibre(measured as NDF).40% starch is found in green plantains .This starch get converted into sugars when they are fully riped. 30% free sugar  is found in ripe bananas and about 15%  starch.Leucine ,valine phenylalanine and threonine are essential amino acid present in considerable quantities .Lysine was the limiting amino acid .The content of lipid varies from 2-10% and was rich in polysaturated fatty acids ,particularly linoleic acid and alpha linoleic acid .Potassium is the most significant element.Starch is more in plantain peel than in banana peel. As the maturation proceeds ,increase in sugar content occur with the decrease in starch due to degradation of starch under the action of endogenous enzymes.

 .Chemical composition of banana peel is carbohydrate ,fiber,potassium ,maganese, iron,sodium. Traces of polyphenoles ,ether extractives and tannic acid is also present in banana depending upon which species of it is used.Many experiments have shown that banana peels have good antioxident potential and can be used for water purification ,for the removal of many toxic metals like copper,lead,cadmium ,chromium and nano particles etc.Banana peels have good compatility to adsorb dyes methylene blue ,ethylene blue and bromophenol before disposal in the water these dyes should be treated with compatible adsorbent to remove their toxicity.
