Eating or using banana peels might be weird to many, but its left abundance is of huge importance to both plant and humans. Nothing in banana is a waste because both the main banana content and its coverings contain huge nutrient values.
Banana peels are good, edible and probably used to its tossing into trash. While a banana’s main flesh is soft and sweet, the skin is fibrous, thick and slightly bitter. A banana peel can be eaten either when blend it into smoothies, fried, baked, or boiled for about 10 minutes. When boiled it breaks down the skin’s fiber and loosens up its tough texture, making it easier to chew and digest.
All fruit contain natural plant hormone called ethylene that makes fruits ripe, when released.
When ethylene is released, it digests the sugars and fiber in the banana skin, converting complex sugars into simple sugars and breaking it down to pectin.
