In the kitchen, it's frustrating when some fruits ripen and rot faster than others. The reason? Certain fruits known as climacteric continue ripening after harvest, releasing ethylene gas that speeds up the process in nearby produce. Bananas, for example, are climacteric fruits—buy them green, and they'll ripen perfectly at home. But stored with non-climacteric fruits, those sensitive neighbors spoil prematurely.
Climacteric fruits vary in ethylene output. High producers include passion fruit, apricot, avocado, nectarine, guava, kiwi, mango, melon, papaya, peach, apple, pear, and plum. Moderate emitters: banana, fig, lychee, and tomato.
Non-climacteric fruits produce minimal ethylene and stay fresh longer post-harvest, including pineapple, raspberry, persimmon, blackberries, blueberries, and watermelon.
Keep climacteric fruits apart from each other and non-climacteric varieties to maintain freshness. Pro tip: Place unripe avocados near bananas to ripen them faster intentionally. To fight rot, add half a cork to your fruit bowl—it absorbs excess moisture effectively.
