How to Store Bananas in a Jar to Keep Them Fresh Longer
Say goodbye to mushy, overripe bananas! This simple jar method helps slow down ripening by controlling ethylene gas and humidity.
What You’ll Need
✅ Ripe but firm bananas (yellow with minimal brown spots)
✅ A large glass jar (like a mason jar) with a lid
✅ Paper towel (optional)
Steps to Store Bananas in a Jar
-
Separate the Bananas
-
Break them into individual bananas (this reduces ethylene gas buildup).
-
-
Wrap the Stems (Optional)
-
Cover each stem with plastic wrap or foil (this further blocks ethylene release).
-
-
Place in the Jar
-
Stand the bananas upright in the jar.
-
Add a dry paper towel at the bottom to absorb excess moisture.
-
-
Seal and Store
-
Close the jar tightly and store in a cool, dark place (not the fridge—cold turns them black!).
-
For longer storage, keep the jar in the fridge after 2 days (the peel may darken, but the fruit stays fresh).
-
Why This Works
-
Ethylene gas (which ripens bananas) is trapped in the jar, slowing the process.
-
The controlled humidity prevents mold and rot.
-
No more fruit flies—the jar keeps pests away!
Bonus Tip: For overripe bananas, peel and store them in a sealed jar in the freezer for smoothies or baking.
How Long Do They Last?
-
Room temperature (jar method): 5–7 days (vs. 2–3 days normally).
-
Fridge (after jar method): Up to 2 weeks.
Perfect for: Meal prep, avoiding waste, or keeping bananas ready for banana bread! 🍌
