Place it in a cold space, such as a refrigerator. The skin 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.

∙ 12y agoTo make bananas ripen, you could leave a bunch in the sun on your kitchen bench for a few hours, but not overnight or they go brown. When you purchase them at the supermarket, leave them in the plastic bag for a few hours.
Bananas ripen faster with moisture and heat. Too much heat and moisture though will send them brown.
