Kiwi fruit is best when it matures in the vine, but certain varieties are just as good when it is matured at home. The trick is to choose a good kiwi to start with. Then, just place it on the kitchen counter and wait for the fruit to reach its peak of flavor and juiciness. See the steps below to learn how to ripen a kiwi the right way.
Method 1 of 2: Ripen the Kiwi
Step 1. Choose a fruit free of bruises
Look for a kiwi that doesn't have dark marks or cuts in the skin. Feel the fruit and choose one that is firm.
- Most of the kiwi varieties found in the supermarket ripen perfectly outside the vineyard.
- If you're growing your own kiwifruit and want to know how to ripen them, check out what variety they are, to see whether you should leave the fruit in the vineyard until ripe or pick it when it's still green.
Step 2. Check the seeds
If you have a lot of fruit to spend, cut one and look at the seeds. The kiwi will not ripen if the seeds are still green or yellow – they should be black. Black seeds indicate that the fruit has enough sugar to ripen properly.
Step 3. Place the kiwi fruit in the refrigerator until it is time to ripen
Green kiwi fruit lasts in the refrigerator for at least four months. Store them alone so they don't come into contact with fruits that produce ethylene, the gas that makes them ripen.
Step 4. Place the kiwi fruit you want to ripen at room temperature
Just put them in a bowl or on the counter and wait a few days. The fruit will ripen in three to five days if left at room temperature.
Do not place kiwi fruit in direct sunlight. This causes them to fade and rot very quickly
Step 5. Accelerate ripening by exposing the kiwi to ethylene
Place it near apples, bananas or pears. This exposes the kiwi to the ethylene produced by other fruits. Keep ripening kiwi fruit out of direct sunlight and away from sources of heat.
To make the kiwi fruit ripen even faster, place it in a paper bag or a ventilated plastic bag along with an apple, banana, or pear. Place the bag at room temperature for one to two days
Step 6. See if the kiwi is ripe by pressing it with your thumb
The fruit is ripe if it yields to light pressure. Ready-to-eat kiwi fruit is plump and fragrant.
Step 7. Eat the ripe kiwi fruit right away
Be sure to eat them when they are at their peak, otherwise they will start to rot.
Method 2 of 2: Store Ripe Kiwifruit
Step 1. Keep ripe kiwi fruit in the refrigerator for up to seven days
You can extend the storage time for another week if it is placed in a plastic bag. The casing reduces dehydration and prolongs freshness.
Step 2. Freeze the entire kiwi fruit
Simply place the whole fruit in a freezer container and leave it there for several months.
Step 3. Freeze sliced kiwi fruit
Kiwi slices are great to garnish or spice up smoothies and other healthy treats. If you have a lot of kiwis, you can slice them to freeze.
- Slice the kiwi and sprinkle the slices with sugar to keep them firm and tasty.
- Place the sugary slices on a baking sheet and place in the freezer.
- Transfer the frozen kiwi slices from the baking sheet to plastic bags. Store in the freezer.
- Kiwifruit needs to be exposed to ethylene gas after being harvested to begin the ripening process that consumers complete after taking them home. If growers and suppliers don't start ripening the fruit, starches aren't converted to sugars quickly enough and the fruit wilts.
- Kiwi fruit is a good source of vitamins and minerals, including vitamins C and E, potassium, magnesium and copper. It is low in calories, high in fiber and contains no fat or sodium.
