A banana will turn brown whether or not it is in a refrigerator. However, a banana will turn brown faster in a cold space, such as refrigerator, than if left in a space that is at room temperature.

The skin of a banana turns brown or black faster in a 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.

A banana does not turn brown faster in a refrigerator.

An enzyme in the banana cells carry out oxidation which coats the banana with a rusty color.

The enzymatic activity slows down near lower temperatures and speeds up in higher temperatures.

Therefore, again, a banana does not turn brown faster in a refrigerator.

However, if you were referring to a Freezer, a faster browning effect can be noticed.

When a banana is frozen, the water in each cell expands because water tends to expand as a solid. This expansion breaks the rigid cell walls and when thawed, the banana is at a less stable condition. Faster decomposition.

Bananas have only 1 cell wall, which is weak too. Thus, when it is kept in the fridge for a long time, the water in the cell wall gets frozen Since the volume of ice is gr8ter than that of water, it cracks the cell wall. thus the banana becomes black.

added that it also freezes a protein of banana which is responsible for color.

Does cold make a banana turn brown faster?

In a word, yes. The skin turns brown or black faster in the cold of a 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.


Why do you not put bananas in the refrigerator?

Actually, you can put bananas in a refrigerator to help keep them from over-ripening. Some say refrigerating a banana changes its taste, but it is better than having it over-ripen or even rotting. 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.
