Many people are under the misconception that all fruits continue to ripen after they are picked.
Fruits that STOP ripening when picked:
Blackberries, Blueberries, Cherries, All Citrus: Clementines, Grapefruits, Lemons, Limes, Oranges, Tangerines
Cucumbers, Eggplants, Figs, Grapes, Olives, Peppers, Pineapples, Pomegranates, Raspberries, Strawberries, Summer squash, Watermelons
The truth is that some stop ripening the moment they are harvested and will rot, mold or dry out once they’ve been picked.
Fruits that CONTINUE to ripen after harvesting:
Apples, Apricots, Avocados (only start to ripen when off the tree), Bananas, Cantaloupes, Guava, Honeydew melons
Kiwis, Mangoes, Nectarines, Papayas, Passion fruit, Peaches, Pears, Persimmons, Plums, Quince, Tomatoes
Commercial growers use ethylene gas to quicken the ripening process and enhance the color of the peel.
-Fruits that stop ripening when picked are best preserved on the tree or bush until ready to eat. Once picked, they should be eaten as soon as possible.
-Fruits that continue to ripen have a longer shelf life and can be picked once they have matured to their optimum size but are still not quite ripe. These fruits produce their own ethylene gas that continues the ripening process.
