Spray-on coating keeps bananas fresh
A spray-on coating made from a substance found in crab shells can prevent bananas ripening too fast and keep them fresh for up to 12 days, scientists claim.
Bananas become mushy and sickly sweet notoriously quickly because unlike most fruits, the rate at which they “breathe” through their skin does not slow down after they ripen.
Instead of remaining ripe for several days this means the fruit continues to produce sugars from its pulp, allowing the bacteria on its skin to multiply which causes the banana to rot – Daily Telegraph writes.
