As these processes continue and the cells within a banana denature, it eventually becomes rotten and pretty unappealing to eat.

Considering all of these chemical changes in composition within the fruit as it ripens and rots, is it possible to revive a gross old banana using rice and heat?

Debate has previously raged on how to store and best extend the life of bananas – should they be left at room temperature or stored in the fridge? Storing bananas in a cold environment drastically slows the conversion of starch to sugars, which means that the flesh stays good for longer. However, when they are placed in the fridge, an enzyme (polyphenyl oxidase) combines with phenols in the peel to create polyphenols, which causes the outer skin to turn brown. So although the fruit inside is still tasty and ripe, the skin looks rotten.

What conclusions did we draw from our investigation? We actually did try this ourselves in the office, and were left with nothing but a still-rotten banana. Perhaps unsurprisingly, we simply have another case of the internet leading us up the garden path for reasons that only the individuals coming up with this rubbish will know.

You can't revive a rotten banana. This leaves us with two hypotheses – by placing the banana in the fridge, the banana flesh is preserved but the skin goes brown (which is what we're seeing in this video). Placing the banana in the rice removes moisture from the skin, and gently heating the banana back to a normal temperature may reverse the effects of cooling on the skin, restoring the color.

...That, or it's simply lighting or computer trickery.
