The “one kitchen item” in this viral banana-storage tip is usually plastic wrap.
🍌 Does it really add 10 days?
Not reliably. Bananas produce ethylene, a natural ripening gas. Wrapping the stems/crown can reduce ethylene escaping from that area and may slow ripening, but the effect varies with temperature, variety, and how ripe the bananas were when purchased.
For longer-lasting bananas:
-
Wrap the stems individually with a small piece of plastic wrap.
-
Keep unripe bananas at room temperature.
-
Keep them away from other ripe fruit, which can increase exposure to ethylene.
-
Once they’re ripe enough, refrigerate them. The peel may darken, but the inside can remain good for considerably longer.
So the headline’s “10 days longer” is an exaggeration, not a guarantee. The stem-wrapping trick can help, but proper temperature and timing matter more.
