[Scientific Power] Whether the fruit needs to be put in the refrigerator, it turned out to be a technical work

Summer and autumn is the fruit harvest period. The fruit is dazzling. At this time, I believe that everyone will buy more fruits to taste at home, and even use the fruits to stuff the refrigerator. However, different types of fruits are different and may not be suitable in the refrigerator. Some fruits are even faster because they are placed in the refrigerator.

So, which fruits need to put the refrigerator? Which fruits do not need? Let's explore the scientific principles.

First of all, tropical fruits are not suitable for the preservation of the refrigerator. The temperature of about 4 ° C in the refrigerator is a bit too low to them, and it will be quickly frozen, such as bananas, oranges, papaya, mango, and kiwi. The faster the refrigerator is, the faster the refrigerator is.

Bananas, mango, and papaya are tropical fruits, and they are in line with the "fear of cold constitution" that cannot put the refrigerator. Both are because the temperature of the refrigerator is too low, it is not suitable for saving, and the normal temperature can be stored. In the summer, bananas with a maturity of 8-9 can be stored at least one week at room temperature. However, if it is stored in the refrigerator, the banana peel will quickly change from yellow, grow a lot of dark spots, the sweetness will become lower, and the taste is not good.

Mango is also similar. It is best for the environment to store between 10 and 13 degrees Celsius. If the mango is not mature, put it directly in the refrigerator, which may not be completely mature, and the taste will not taste good. And if mango is in a low temperature environment for a long time, its epidermis is also prone to black spots, which will lead to decay. The same is true for papaya. Put a large amount of black spots in the refrigerator, and the flesh will rot due to frostbite. Therefore, papaya is best wrapped in dry newspapers and stored it in a cool vent.

Orange and kiwi are special. They are not tropical fruits, but they are not suitable for putting in the refrigerator due to their own characteristics. Orange peel is rich in oil and taste bitter. If it is kept at room temperature, the orange can volatilize the fat through breathing. However, if the oranges are preserved, the fat of its skin cannot be volatile, and finally it enters the flesh. The orange will not taste sweet and it will be bitter.

Kiwi is more resistant to storage itself. If the temperature is not higher than 30 degrees, it can be maintained for a long time at normal temperature. But if the kiwi is refrigerated in the refrigerator, the color of the epidermis will become darker, and it will be easier to rot.

Of course, there are also some fruits that are very suitable for putting in the refrigerator. For example, watermelon, litchi, longan, cantaloupe, etc. are suitable for placing in a refrigerator above 0 ° C, and like apples, Sydney, grapes, strawberries, etc., can be placed in 0 in 0 In the temperature around ℃. In general, everyone must recognize the attributes of different fruits to determine whether to put the fruits in the refrigerator.
