Here are several ways to soften kiwi fruits that are hotly discussed across the internet:
| method | Operation steps | time required | Effect evaluation |
|---|---|---|---|
| Place at room temperature | Keep kiwis at room temperature and away from direct sunlight | 3-5 days | The most natural method, but it takes longer |

2. The scientific principle of kiwi fruit softening
The process of kiwi fruit softening is actually the post-ripening process of the fruit, which is mainly related to the release of ethylene gas. Ethylene is a natural plant hormone that promotes fruit ripening. Here are the different ways to promote ethylene release from kiwi fruits:
| method | scientific principles |
|---|---|
| Fruit ripening method | Fruits such as apples and bananas release large amounts of ethylene, which accelerates the ripening of kiwi fruits. |
| Rice ripening method | Rice can absorb moisture around the kiwi, creating an airtight environment that promotes ethylene accumulation. |
| paper bag sealing method | Sealed environment prevents ethylene from escaping and increases local ethylene concentration |
| Warm water soaking method | Appropriate heating can activate the enzyme activity in kiwi fruit and accelerate the ripening process. |
3. How to judge whether kiwi fruit is ripe
During the ripening process, we need to learn to judge whether the kiwi fruit has reached the ideal maturity:
| Judgment index | mature characteristics |
|---|---|
| touch | Press gently and there will be slight elasticity at both ends. |
| Aroma | Distinctive fruity aroma |
| Appearance | The color of the peel becomes slightly darker |
| weight | It feels a little heavier than when I first bought it |
4. Precautions
In the process of ripening kiwi fruits, you need to pay attention to the following points:
1. Do not place kiwi fruit in the refrigerator to ripen. Low temperature will inhibit the effect of ethylene and delay the ripening process.
2. Avoid exposing kiwi fruits to direct sunlight. High temperatures may cause the fruit to deteriorate.
3. The ripened kiwi fruit should be eaten as soon as possible or stored in the refrigerator.
4. If the kiwi fruit has become soft but smells of alcohol, it means it is overripe and should not be eaten.
