Bananas, one of the UK's most popular fruits, often turn brown before they can be eaten. Food storage experts say that wrapping the stems in cling film, a common kitchen item costing less than £1, can keep them fresh for up to five days longer.
How Cling Film Slows Ripening
The trick works by reducing ethylene gas released from the stem. According to Dole, bananas naturally produce ethylene gas as they ripen, with most gas escaping through the stems. Wrapping the crown of the bunch with cling film slows this process.
The United States Department of Agriculture (USDA) states that bananas continue to ripen after picking due to ethylene gas. Proper storage makes a noticeable difference in freshness.
Best Practices for Banana Storage
Dole recommends tightly wrapping the stems of a bunch with cling film or plastic wrap to keep bananas fresh for three to five extra days. For best results, wrap each banana stem individually after separating them from the bunch.
Love Food Hate Waste advises storing bananas at room temperature while green or yellow. Refrigeration darkens the peel more quickly, though the fruit inside often remains edible. Keep bananas away from other fruit like apples, pears, and avocados, which also release ethylene gas and can speed up ripening.
Additional Tips to Extend Freshness
Experts recommend storing bananas in a cool, dry place away from direct sunlight or heat sources. Hanging them on a banana hook or allowing air circulation can reduce bruising and extend freshness. Even if skins develop brown spots, the fruit inside is often safe to eat. The USDA notes that overripe bananas can be frozen for smoothies, banana bread, or baking, reducing food waste.
