The starches are converted to sugars.
A starch is actually a long chain of sugar molecules. As the fruit ripens, the starches break apart into the sugar molecules. This is why they become sweeter as they ripen.
A banana takes on a slight bend as it ripens. A green, unripe banana is usually straighter.
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.
Ethylene causes the ripening process, which also causes the color change.
i think bananas
The answer is no. There are no substances in bananas, so there is no precipitation.
ethylene
Because it is losing water content, which had caused the tissue of the banana skin to swell.
I am not really know maybe one year.-_-
Because when they are kept in the fridge, fruits such as apples will lose water, and their sugar will crystalise, causing themselves to become sweeter.
A banana will slowly inflate a sealed balloon or plastic bag because it gives off gases (notably ethylene) as it ripens. However, if a banana is too ripe, it may oxidize and remove oxygen from the air.
Fruit gets sweeter as it ripens due to fermentation. The starches within the fruit are slowly converted to sugar as it sits.
