Bananas are a convenient and naturally sweet breakfast option, but they can go bad quickly, often within just a few days of purchase. A simple storage hack can make a significant difference, and it comes down to where they are kept.
Why fruit bowls cause bananas to rot
Katherine McPhillips, a writer for The Express, learned she had been storing bananas incorrectly, which is why they rotted so fast. She explained that putting bananas in a fruit bowl is actually the worst place for them in the kitchen, as they will begin rotting if stored next to other fruit. Most fruit produces ethylene, an invisible gas that ripens fruit to make it taste sweeter, but too much of it in the air speeds up the ripening process.
When bananas are grouped with other fruit, the ethylene triggers spoilage rather than proper ripening, preventing them from staying fresh. Bananas naturally release the largest quantities of ethylene, which is why they must be kept separate from other fruit to avoid widespread rotting and decomposition.
The worktop experiment
McPhillips discovered this after accidentally leaving bananas on a kitchen worktop corner for several days following a shopping trip. She noticed they remained much fresher and retained their yellow colour, so she has since kept them in a bowl far away from any other fruit.
This method preserves banana freshness for at least seven days. To extend their quality further, wrapping the stems with tin foil helps. McPhillips found that bananas release ethylene gas through their stems, and covering them significantly reduces this.
Why tin foil works best
Lower ethylene levels in the surrounding air kept bananas fresh for a minimum of 10 days in her experiment, with many lasting up to 14 days or beyond. Tin foil provides the best protection, as cling film creates an overly tight seal that may trap moisture and lead to mould. Baking paper is too breathable, allowing ethylene to escape readily, making it ineffective. Tin foil creates a proper seal while keeping out moisture.
McPhillips has used this method for months, and the minor adjustment has kept bananas bright yellow for weeks instead of days, helping her save on her food shop.
