What is the fastest way to ripen kiwi fruits?

Place unripe kiwi fruits in a paper bag with a banana or apple. These fruits produce ethylene gas, which tells the kiwis to ripen. Simply leave the bag on your kitchen counter at room temperature, keeping it away from light or heat. Most firm kiwi fruits will ripen in 1 to 2 days.

  1. Kiwi fruit continues to ripen after it’s picked—if you bought some firm, unripe fruits, they’ll soften and sweeten up at home. Just place the kiwis in a bowl on your countertop and keep them away from direct sunlight and heat, as this can cause them to rot quickly or get discolored. [1]
    • How long does it take the kiwis to ripen? Most firm kiwi fruits will ripen on the counter in 3 to 5 days if stored at room temperature.
    • Most kiwi fruits that you find in the grocery store, like the green and golden flesh varieties, ripen perfectly fine off the vine.
    • If you're growing your own kiwi fruit plant , check the variety you have to determine whether you should leave your fruit on the vine until it's ripe or harvest it while it's hard.
  2. The quickest way to ripen a firm kiwi fruit is to store it near fruits that produce ethylene gas, like bananas, apples, and pears. This exposes the kiwis to more ethylene, which tells them to ripen faster. Simply place the kiwis in a paper bag with the other fruits and keep them on your counter at room temperature. [2]
    • How long does it take the kiwis to ripen? Most firm kiwi fruits will ripen in 1 to 2 days when kept in a paper bag with a banana or other fruit that produces ethylene gas. [3]
    • Keep the bag out of direct sunlight and away from heat sources, as this can cause the fruits to rot quickly.
    • Do not place the kiwi in a plastic bag. This can reduce air flow and trap moisture, causing the fruits to rot and grow mold.

How to Tell If Kiwi Fruits Are Ripe

  1. Watermark wikiHow to Ripen Kiwi Fruit
    According to Dulaney, the best way to tell if a kiwi fruit is ripe is to give it a gentle squeeze with your thumb. If the kiwi is mostly firm with a little give and softness, it’s perfectly ripe.
    • Avoid kiwi fruits that are very soft or mushy, advises Marrow Private Chefs, as this is a sign that they’re overripe and will go bad quickly.
    • Remember, if you pick a kiwi that’s very firm and unripe, it’ll soften and sweeten up if you leave it on your counter at room temperature.
  2. 2
    Smell the kiwi for a sweet, fruity scent. When kiwi fruits ripen, they have a noticeable and pleasant fruity smell. If the scent is very faint or nonexistent, the fruit is probably unripe. And if the kiwis smell fermented, sickly sweet, or slightly sour, they’re most likely overripe and starting to rot. [4]
  3. Look for a kiwi fruit that doesn't have any dark spots, bruises, mushy areas, or tears in the skin. The fruit should be plump and round without any wrinkles, flat spots, or sunken areas. [5]
    • Most kiwi fruit varieties that you find in the store have brown, fuzzy skin. However, there are some varieties that have red or green skin.
  4. Watermark wikiHow to Ripen Kiwi Fruit
    If you have a lot of fruit to spare, cut a kiwi open and look at the seeds. A kiwi is unlikely to ripen if its seeds are still green or yellow—the seeds must be black. Black seeds indicate the kiwi has enough sugar to ripen properly. [6]
  5. Watermark wikiHow to Ripen Kiwi Fruit
    Make sure to eat the kiwi fruit when they're at their peak ripeness, or within about 1 to 2 days when left on your counter. Because kiwis continue to ripen at room temperature, they can get overripe and start to rot quickly.

Storing Kiwi Fruits

  1. Watermark wikiHow to Ripen Kiwi Fruit
    If you have some hard kiwi fruits that you’re not ready to ripen yet, simply keep them in your fridge. The cool temperatures slow down the ripening process, so the fruits will stay good for about 1 month. Just place the kiwis in your crisper drawer away from fruits that produce ethylene gas, like apples and pears. [7]
    • Storing the kiwis near fruits that produce ethylene gas can cause them to ripen quicker, so they won’t keep as long in your fridge.
  2. If the kiwi fruits are ripe but you’re not ready to eat them yet, simply stick them in your fridge’s crisper drawer. They’ll keep well for about 5 to 10 days. Just keep them away from apples, pears, and other fruits that produce ethylene gas so they don’t get overripe quickly. [8]
    • Feel free to store the kiwi fruits loosely or place them in a plastic bag. Keeping them in a bag might help extend their freshness by reducing dehydration.
  3. 3
    Keep cut kiwi fruit in an airtight container for 2 to 7 days. If you have some leftover kiwi after cutting it, simply place the pieces in a glass or plastic storage container. Then, set the container in your fridge’s crisper drawer. The fruit will keep well for about 2 to 7 days. [9]
    • If the kiwi fruit starts to look mushy and smells off or acidic, it’s probably gone bad , so compost it or throw it away.

  1. Watermark wikiHow to Ripen Kiwi Fruit
    If you have extra kiwi fruits on hand that you aren’t planning on eating right away, slice them up and freeze them. Frozen kiwi slices make great garnishes in drinks or additions to smoothies and other healthy treats. Or, let the slices thaw in the fridge overnight and enjoy them as a snack. [10]
    • Remove the skin from the kiwis and cut them into slices or chunks.
    • Sprinkle sugar on the slices to keep them firm and flavorful (optional).
    • Put the slices on a lined baking sheet and slide the sheet into the freezer.
    • Let the slices freeze for 1 to 2 hours.
    • Transfer the frozen kiwi slices into plastic freezer bags.
    • Write the date on the bag and store the slices in the freezer for up to 1 year.
    • Note : You can freeze kiwi fruits when they’re ripe or unripe. Just know that unripe kiwis usually taste less sweet and more sour than ripe fruits.
  2. If you don’t want to spend time chopping up kiwi fruits, you can freeze them whole, too. Simply place whole kiwi fruits in a plastic freezer bag, write the date on the bag, and store them in the freezer for up to 1 year. [11]
    • It can be difficult to peel the skin from frozen kiwi fruits, so consider removing it before you freeze the kiwis.
    • Add whole frozen kiwi fruits to smoothies, sorbets, and popsicles. Just know that they might take longer to blend up than sliced kiwi.
    • If you want to thaw the frozen kiwi fruits, simply place them in your fridge overnight.

      Tips

      • Kiwi fruits are good sources of vitamins and minerals, including vitamins C and E, potassium, magnesium, and copper. Kiwi fruits have few calories, are high in fiber, and contain no fat or sodium. [13]
      • Kiwis must be exposed to ethylene gas after they’re picked to start the initial ripening. If the growers and shippers don't begin to ripen the fruit, the starches aren't converted to sugars quickly enough, and the fruit shrivels.
