Bananas produce ethylene gas through the stem, and wrapping up creates a barrier which contains the gas at the source and prevents it from affecting the rest of the bananas.

The clingfilm will greatly slow down the ripening process and help extend a banana’s shelf life by several days.

Rose said: “Keep [the wrap] on until you are ready to eat it and this will keep your banana for about four or five days looking good and tasting great.”

In Rose’s comment section, many people praised the storage method and said it had worked for them.

One user said: “It does work! Great advice.” While another person wrote: “I’ve been doing this for years and it keeps them fresh.”

Someone else added: “I do this and aluminium foil [works] the same.”

Another commentator added: “Smart! It’s always fun to learn something new.”

However, one user named Richard also shared that any bananas that become ripe can be sliced and frozen to use for breakfast and cut down on food waste.

He said: “You can slice them, and freeze the slices on a tray or plate. Once frozen, put the slices in a sealed bag and keep them in the freezer. Add slices to your oatmeal.”
