"Can bananas go in the fridge?" and "Do apples spoil the fruit next to them?" are questions asked the world over. Fruit divides into kinds that ripen after picking and kinds that do not, and that difference decides how to store it.
| Ripens after picking (ripen at room temperature, then chill) | Does not ripen after picking (chill from purchase) |
|---|---|
| Bananas, avocados, kiwis, peaches, pears, mangoes, melons, persimmons (some) | Strawberries, grapes, cherries, citrus, apples (already ripe), pineapples, watermelon (room temperature is fine until cut) |
| Fruit | Storage guide | Note |
|---|---|---|
| Bananas | Room temperature; once ripe, the fridge is fine (the skin turns black, the inside is still edible) | Chilling injury below 13°C (55°F) |
| Apples | Fridge (in a plastic bag) | Give off a lot of ethylene. Keep apart from other fruit |
| Strawberries | Fridge, 2–3 days. Wash just before eating | Spoil easily |
| Citrus | Cool room temperature to fridge | Prevent drying out |
| Avocados | Ripen at room temperature → fridge | Once cut, lemon juice slows browning |
[Verify] Check the ripening classification and the explanation of ethylene against MAFF and NARO (National Agriculture and Food Research Organization) material, and the temperature figures against each source.
The skin turning black is chilling injury; the flesh stays as ripe as it was. Chilled once ripe, bananas keep several days longer than at room temperature.
Apple ethylene speeds ripening, so keep apples away from fruit that must not over-ripen (strawberries, grapes). Put them with avocados or kiwis you want to ripen quickly and they become useful.
Washing removes the protective surface layer, and the moisture makes fruit spoil faster. Strawberries and grapes in particular should be washed just before eating.
Bacteria multiply readily on a cut surface. Under the Ministry of Health, Labour and Welfare's approach to food-poisoning prevention, cut fruit goes in the fridge and should not sit out for more than 2 hours. Eat cut fruit the same day.
Freezing does not greatly reduce vitamin C and the like; for long storage, nutrients are generally described as better kept frozen than chilled. Bananas, berries and mangoes are frozen for smoothies and so on, which also cuts food waste.
