Store tomatoes stem end down to keep them from spoiling as quickly. This prevents air from entering and moisture from exiting the scar where the tomato once attached to the vine. Storing them at room temperature rather than in the fridge also makes them last longer.
Keep Bananas Yellow Longer
Keep bananas fresher, longer by wrapping the end of the bunch with plastic wrap. Better yet, separate each banana. The plastic wrap blocks ethylene gases from releasing out of the stem, which makes ripening process faster.
Speed Up Ripening
If you want to speed up ripening, place your fruit in a paper bag. In the bag, concentrated ethylene gas helps it ripen quicker.
