Which fruits should not be frozen in the refrigerator in general

After opening the durian, if you find that the flesh has changed color, some blackened, and the smell emitted is also disgusting, then it can be concluded that the durian is bad. At the same time, if the durian has the smell of wine and smells particularly pungent, it can also be concluded that such a durian has gone bad.

1. Bananas. If the banana is stored below 12, it will be black and rotten, and the refrigerator compartment is zero degrees. Some tropical fruits, such as blue-colored bananas, are less cold-tolerant when they are bought and are not stored in the refrigerator.

Otherwise, not only will they not ripen properly, but they will also rot and become inedible.

2. Tomatoes.

After the tomatoes are frozen at low temperature, the flesh will be blister-like, soft or spalled, and there will be black spots on the surface, undercooked, no umami, and even rancidity. It is recommended to store in a dry and low temperature place to maximize flavor preservation.

3. Durian. Durian has the property of ripening, it should be stored in a cool place, the ripe fruit will be cracked, then the pulp can be taken out, put in a fresh-keeping bag and stored in the refrigerator, after chilling, it will have the taste of ice cream. If the flesh of the fruit becomes rancid, it means that the durian has spoiled, and it is advisable to continue to eat it if you do not slow down.

4. Mango. Mango is a tropical fruit, loves drought, and is most afraid of low temperatures, so it is best not to put mango in the refrigerator, otherwise the peel will turn black, so it is not advisable to overdo it every time you buy mango, if you can't eat it all at once, it is best to pick some slightly green mangoes when buying, and let it ripen naturally at 20-25 conditions.

5. Papaya. Papaya is also a fruit that cannot be stored in the refrigerator, because as long as the papaya touches the water, black spots will appear, and although the refrigerator has the effect of absorbing water, once the refrigerator is taken out, the temperature difference will cause moisture on the surface of the papaya, and stale black spots will appear. The correct way to store papaya should be:

Wrap the papaya in newspaper and store it in a cool place. In this way, the papaya can be stored for a long time, and the fresh state is always guaranteed.

6. Rambutan.

When rambutan is stored at 1 -2 levels, the color of the exocarp will become darker, and the endocarp will have some spots like burns, and such fruits are often no longer edible. Rambutan should be bought and eaten immediately, should not be hidden for a long time, and will change color after 3 days at room temperature.

Tropical fruits should not be put in the refrigeratorFor example, bananas, pineapples, mangoes, papayas, lemons, etc. are stored at a temperature higher than the refrigerator temperature, in fact, these fruits can be stored in a cool place indoors, and if they are stored in the refrigerator for a long time, the peel will be dented, easy to spot or brown.

For example, the best storage temperature of mango is about 10 -13, and the peel will turn black if the temperature is lower than 8; Unpeeled pineapples can generally be stored for a month at a temperature of 11-13, and they are easy to spoil when put in the refrigerator; Bananas are best stored between 8 and 23, and the high temperature is easy to overripe and black, while the temperature is lower than 5, it is easy to have frostbite and blacken; The optimal storage temperature of papaya is around 7.

Guava can be stored for 2-3 weeks at 5-10 temperature, and the temperature is lower than 5, and the guava will cause flesh damage and decay due to freezing; Passionflower is also very sensitive to temperature, cold can suffer from frost damage at low temperatures, mold at high temperatures, and its best storage temperature is about 6.

1. Put the fruit into a plastic bag or fresh-keeping bag, and then put it in the refrigerator, which can slow down the speed of fruit deterioration and prolong the storage period.

Use plastic bags or fresh-keeping bags to store fruits, open the mouth of the bag every two or three days to change the air, and then tie the mouth to reduce the occurrence of rotting and deterioration. Wrapping the fruit tightly with plastic wrap can also play a role in extending the shelf life of the fruit, but every two or three days, the plastic wrap should be replaced.

2. Different fruits need to be stored separately.

Some fruits produce ethylene when stored, which has the effect of ripening. For example, apples, pears, bananas, etc., it is best to store them separately from other fruits, so as not to accelerate the ripening and aging of the fruits, affecting the quality.

Fruits that cannot be put in the refrigerator are: bananas, dragon fruit, mangoes, papaya, kiwifruit.

1. Bananas. If the banana is rotated below 12 to store, the banana will turn black and rot. Bananas are tropical fruits, and the suitable storage temperature is about 12, while the temperature of the refrigerator is generally 0 4, so if you put bananas in the refrigerator, it is easy to suffer from cold injury, reduce nutrition, and even cause rot.

2. Dragon fruit.

Dragon fruit is a green, healthy fruit. Dragon fruit is best bought and eaten fresh, and the shelf life can exceed 2 weeks at room temperature of 25 -30.

3. Mango. Mango is known as the "king of tropical fruits", mango likes warmth and is not frost-tolerant, so it cannot be put in the refrigerator. Fresh mango is wrapped in a clean napkin and stored in a cool and ventilated place, and it should be eaten as soon as possible, otherwise it will have black spots.

4. Papaya. Papaya is also a fruit of the Thermoki belt, and like bananas, it is very green when it is first picked and turns yellow after two days. Papaya is similar to mango, it is wrapped in a napkin or newspaper and placed in a cool and ventilated place.

When you buy it, you can pick a little cyan and put it home for 2 days to mature.

5. Kiwi.

When the kiwifruit is first picked, it is very hard and the taste is also very sour, and it is usually put in a bag to "cover it", that is, it will become soft and sweet when it is ripened by itself. To preserve dragon fruit, it should also be placed in a cool and windy place, not at low temperature or high temperature.

There are some fruits that require the temperature at which they should be stored, and the lower the better. For example, the following kinds of fruits, it is best not to put them in the refrigerator to refrigerate, the temperature is too low will make them spoil faster.

1. Mango. Mango is a tropical fruit.

Generally, it is stored in an environment of 10 to 13 degrees Celsius.

, relatively intolerant to low temperatures. The temperature in the refrigerator is generally lower than 5 degrees, if the mango is not ripe and directly put in the refrigerator for refrigeration, it may not be completely ripe, and the taste is not good. And when exposed to low temperatures for a long time, the skin of mangoes is prone to black spots, which leads to rot.

2. Bananas. Bananas are also tropical fruits, which are prone to black spots and rot when stored at low temperatures, and their sweetness will decrease after being stored in the refrigerator. Therefore, it is best to store it at room temperature, but remember to store it in a cool place, too high a temperature will also make the banana rot.

3. Lychee. It is best not to store lychees in the refrigerator, as too low a temperature will cause the skin of lychees to be frostbitten and the flesh to become tasteless. In some places, lychees are stored in the freezer so that they can be eaten in winter.

However, if you have frozen lychees, you should know that if you have frozen lychees, you will lose a lot of sweetness when you put them in a low-temperature environment for a long time, and the skin will become very dry, and most of the lychee flavor will change. 

4. Kiwi.

Kiwifruit itself is a relatively shelf-stable fruit. If the temperature is not higher than 30 degrees, it can be kept at room temperature for a long time. But if we put the kiwi fruit in the refrigerator and refrigerate it, we will find that the color of the kiwi skin will become darker, and the inside will be more perishable.

You can't see anything from the outside, but when you peel it off, you can see that the flesh is soft and rotten, and there is a lot of water loss, so it is not so sweet. If you buy unripe kiwifruit and put it in the refrigerator to refrigerate, it is easy to cause the kiwifruit to not be fully ripe, even if it is left for a long time, the flesh inside is still hard.

5. Papaya. Papaya is also a tropical fruit, and there is a very important condition in its storage conditions: it cannot come into contact with water, and after papaya comes into contact with water, if it is not eaten in time, the peel will appear black spots.

Although the low temperature of the refrigerator will not cause any damage to the papaya, we all know that the refrigerator is relatively low, and after the papaya is taken out of the refrigerator, the temperature difference between indoor and outdoor will be relatively large, which can easily lead to moisture on the surface of the papaya. There is also a lot of moisture in the refrigerator, which can easily get on the skin of the papaya, so that the papaya will appear dark spots and slowly begin to rot from the inside. If you want to preserve papaya, you only need to wrap it in newspaper or kitchen paper to avoid eye contact with moisture in the air, and then store it in a cool place for a longer time.

6. Pineapple. The environment in which pineapple grows is generally relatively hot, and if it is stored in an environment below 6 degrees for a long time, the flesh will easily change, and it will taste particularly loose, and at the same time, the sweetness will decrease, and the taste will not be very good.

Many families wash fruit and store it in the refrigerator after buying it, which is hygienic and keeps the fruit and vegetables fresh. In fact, this is not scientific. The humidity in the refrigerator is high, which can easily become a "breeding ground" for bacteria.

Generally, fruits and vegetables have a layer of wax on the surface, which has the effect of protecting them from microorganisms.

After washing vegetables and fruits, especially after cleaning them with detergent, the waxy layer on their surface will be destroyed, and bacteria can easily enter the inside of vegetables and fruits, resulting in deterioration and decay of vegetables and fruits, and will cause acute enteritis and even dysentery after eating.

Extended information: How to store food properly in the refrigerator.

1. Do not put bottled drinks in the freezer.

Do not put bottled liquid beverages in the freezer to avoid freezing and cracking the bottle. These beverages should be stored in a cooler or on a door stall at a temperature of around 4.

2. Put the food after it is sealed.

Food can be placed in separate utensils, fresh meat, fresh fish should be processed and sealed in a plastic bag, and then put in the refrigerator, vegetables and fruits should be dried with internal moisture, and then put in the refrigerator.

3. Store raw and cooked food separately.

Raw and cooked foods should be stored separately and try not to mix together, which can be a good way to ensure that the food is clean and hygienic. We should make reasonable use of the space inside the refrigerator according to the storage time and temperature requirements of the food.

4. Let the food cool before putting it in the refrigerator.

When the food is still very hot, we should not put it directly into the running refrigerator, so it is easy to indicate that the outside temperature of the food is very low and the internal temperature is very high, and the food will be easily spoiled, reducing the preservation effect of the food.

5. There should be a gap between foods.

The food stored inside the refrigerator should not be too full or too tight, and some gaps should be left in the middle, which is conducive to air circulation, and the cold air convection inside the refrigerator can well reduce its load pressure, so as to achieve the purpose of prolonging the service life of the refrigerator, and at the same time can also reduce the energy consumption of the refrigerator, killing two birds with one stone!

1. Tomatoes: The low temperature of the refrigerator will make the tomatoes wilt, so they should be stored at room temperature (if the unripe tomatoes can be placed on the windowsill to receive a little sunlight).

2. Apples: Fresh apples should be placed on your coffee table, delicious and delicious, but if you haven't eaten apples after a while, you can put them in the refrigerator if you want to keep them longer.

3. Bananas: The purchased bananas usually need to be left for a period of time to ripen thoroughly, but the low temperature environment will greatly slow down this ripening process, which also means that if you put a green banana in the refrigerator, it will be green for a long time.

4. Jam: The production of jam itself uses a variety of additives, which does not need to be stored in the refrigerator at all, and will not be broken, and the same is true for jelly.

5. Melons and fruits: uncut melons, such as melons, will taste better when stored at room temperature, and the United States Department of Agriculture has shown that melons and fruits stored at room temperature can completely preserve their antioxidants, which is more beneficial to health, but once the melons and fruits are cut, they can be stored in the refrigerator for three to four days.

6. Stone fruits: All yellow peaches, nectarines, plums, apricots and other stone fruits need to be placed at room temperature to fully ripe, if you can't eat them all at once, you can store them in the fruit box in the refrigerator for a few days.

7. Grapes: Grapes can be stored at room temperature for up to a week, be careful not to store them with high-ethylene fruits such as apples, kiwifruit, pears, etc. When eating grapes, rinse them with cool water and dry them to eat.

Fruits that can't be put in the fridge:

1. Banana: often planted in temperate and tropical areas, can be harvested all year round, rich in potassium and magnesium, and is a high-calorie fruit. The cold tolerance is poor, and the banana will be black and rotten when stored in the refrigerator.

2. Tomatoes: After tomatoes are frozen at low temperature, the flesh will be blister-like, soft or splintering, and there will be black spots, undercooked, no umami, and even rancid and rotten.

3. Longan: Longan is stored under 1 -2, and the color of the exocarp will become darker.

4. Lychee: Fresh lychee will turn its skin black and its flesh will taste when left in an environment of 0 for a day.

5. Papaya: Papaya will have black spots when it encounters water, and although the refrigerator has the effect of absorbing water, once the refrigerator is taken out, the temperature difference will cause moisture on the surface of the papaya, and stale black spots will appear.
