Does banana contain fat and starch?
Bananas are a good source of dietary starch. Different types of bananas have different percentages of starch content. As bananas ripen the starch changes to dextrin and glucose. Cooking bananas (plantains) are about 25% starch, which is much more starch that 'eating' bananas have, which can be in the range of 5% to 6% of the edible part of the fruit.

Why don't some fruits have starch?
Some do. Plaintains and breadfruit are very high in starch, as is the good old banana!

Where does chemical digestion begin for starches?

Are green bananas a starch?
Certain enzymes in bananas convert starch in the banana into sugar, which is part of the ripening process and what makes the fruit sweeter and softer as it ripens. Therefore, the greener the fruit is the more starch it will contain.
When a green banana turns yellow a sit ripens. What kind of change is taking place?
What causes a banana's peel to turn brown or black and what causes the fruit to ripen are two different things. A banana's peel turns brown due to an enzyme (polyphenyl oxidase), which is naturally found in the banana. The enzyme polymerises phenols in the banana skin into polyphenols. Polyphenols are similar to melanin, the pigment responsible for the color in our skin. This is what blackens the skin of the bananas.The enzyme that makes bananas sweet is called amylase. Amylase breaks down the starch in the banana fruit. When the starch is broken into its smaller sugar components, called glucose, the banana tastes sweet. The enzyme that softens the banana is called pectinase. Pectinase breaks down the cell walls in the banana fruit so that it is less firm.

How does starch delays the ripening of banana?
Placing a banana in a refrigerator will stop the ripening process, and doing so will prevent the further ripening of the fruit, even after it has been removed from the refrigerator. Therefore, store the fruit in a refrigerator only after it has reached the desired stage of ripeness. The skin of a banana turns brown or black faster in the refrigerator, but the banana meat itself does not ripen that much more. In fact, it is recommended that ripened bananas be frozen to preserve them even longer. The cold temperature of a refrigerator encourages an enzyme (polyphenyl oxidase), which is naturally found in the banana, to polymerise phenols in the banana skin into polyphenols. Polyphenols are similar to melanin, the pigment responsible for the color in our skin. This is what blackens the skin of the bananas. Despite the color, the cold temperature will keep bananas firmer than a banana that has been left at room temperature for the same amount of time. The enzymes that break the starch into sugar, which makes the banana soft and ripe, work better at room temperature.
