The secret behind fresh supermarket bananas

Supermarkets keep bananas fresh using a controlled environment. They maintain a cool temperature of 13°C to 15°C and high humidity of 90–95%. This special care dramatically slows down ripening, keeping them perfect on the shelf.

Why do they spoil in just two days at home?

At home, the room temperature is usually above 25°C, which speeds up ripening. Bananas release ethylene gas, and when kept in a bunch or with other fruits like apples and tomatoes, this gas gets trapped and makes them turn black even faster.

Is a blackened banana spoiled?

A black peel doesn't mean the banana is spoiled! It's often just a 'chilling injury' from the fridge, and the fruit inside is actually sweeter. Only throw it away if it smells bad, has mould, or is unusually mushy and leaking.
