bananas will brown faster in a refrigerator because of the cold air.
The skin turns brown or black in the refrigerator, but the banana meat itself does not ripen that much. 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.
There are three main factors involved in the ripening and browning process, they are: enzymes, oxygen and phenols. Enzymes are protein-like substances that speed up or initiate chemical reactions. Phenols are defensive mechanisms the plant uses to fend off insects and microbes. The specific enzyme is called polyphenoloxidase. When the banana is attacked, the phenols are activated in the presence of oxygen by this enzyme. In this process the brown color is produced as a side effect. The first time the banana is attacked is when it is cut from the tree. Exposure to cold air, certain gases, and physical damage of the fruit will hasten the process.

in the refrigerator
It does not matter what brand. Bananas turn brown faster in the refrigerator.
Because banana's grow in a hot country so do not cold conditions such as fridges or freezers!
because the refrigerator keeps it fresh and at one temperature. the counter changes temperature. Acetylene gas in the confinement of refrigerator hastens the browning process in banana.

a banana peal is what you get when you peal a banana
because the refrigerated heat carbons take out the orginated cells quicker.
The stuff that makes the banana Brown wants to make the fruit more brown but it fails
The banana in the refrigerator browned faster than the banana on the counter. The cold temperature makes a banana's skin brown faster. The banana in the refrigerator is still firm though, where as the banana on the counter is softer.
Take two bananas on the same stem, separate them and place one in the refrigerator and the other on the counter to see which will brown faster.
Apples will ripen faster on the counter than in the fridge.
