Fruits and veggies naturally emit an odourless, harmless, and tasteless gas called ethylene, and some produce it in greater quantities than others. When ethylene-producing foods are stored next to ethylene-sensitive foods, the gas will speed up the ripening process of the other produce. This is great if you need to ripen a piece of produce, for example, pair an apple with an unripe avocado. However, if you don't want to speed up the ripening (or decay) process, store or keep the following fruits and veggies separate.
Produce That Creates Ethylene Gas: Apples, apricots, avocados, ripening bananas, blueberries, cantaloupe, citrus fruit (not grapefruit), figs, grapes, green onions, ripe kiwi fruit, mangoes, melons, mushrooms, nectarines, papayas, passionfruit, peaches, pears, peppers, pineapple, plums, prunes, tomatoes and watermelon.
Produce That Is Damaged by Ethylene Gas: Asparagus, broccoli, brussels sprouts, cabbage, carrots, cauliflower, cucumbers, eggplant, green beans, kale, kiwi fruit, leafy greens, lettuce, parsley, peas, peppers, potatoes, romaine lettuce, spinach, squash,sweet potatoes.
