The refrigerator is to reduce the speed of various chemical reactions in food through an artificial low-temperature environment, which is conducive to preserving the quality of food. In ordinary life, frequent opening and closing of the refrigerator door can cause the temperature in the refrigerator to rise, and bacteria in the food will grow, and the refrigerator will also produce a kind of germs ———psychrophiles" that contaminate the food. This fungus can grow in a 0 4 environment, hide in a variety of foods such as meat products, dairy products, vegetables, seafood, etc., and multiply fastest at 4 6 hours, which is the temperature of the refrigerator room.
Therefore, the refrigerator should be cleaned and disinfected regularly, especially in summer.
It's important to note that not all food is suitable for fridge storage. Some foods are in the refrigerator, which will shorten the shelf life; Some foods can be stored for a long time without being kept in the refrigerator, such as biscuits, candies, honey, pickles, yellow sauce, preserved fruits, powdered foods, dried foods, etc. They either have very low water content and microorganisms cannot multiply; Or the concentration of sugar and salt is too high, there is very little free water, and microorganisms cannot multiply.
At the same time, tropical fruits such as mangoes and bananas are suitable for storage at about 12 years old, and they can be stored in a cool place at room temperature. If you put them in the refrigerator, they will be damaged by freezing and deteriorate prematurely.

I know bananas, chocolates, fresh lychees, tomatoes.

tropical fruits such as tomatoes and bananas;
Foods that are not perishable and do not need to be kept fresh.

Don't put these 10 foods in the fridge:
1. Starchy foods.
Starchy foods such as steamed buns, flower rolls, and bread cannot be put in the refrigerator, which will speed up the speed of drying and hardening, and if you can't eat them for a short time, you can seal them and put them in the freezer to freeze. In addition, bread and biscuits should not be stored together, so that the moisture in the bread will be transferred to the biscuits, making the biscuits soft and the bread hard, which is not good for both.
2. Chocolate.
After the chocolate is taken out in the refrigerator, the surface is prone to white frost, which not only loses its original mellow taste, but also facilitates the reproduction of bacteria. Rui Lily says that the best temperature for storing chocolate is 5 to 18 . In summer, when the room temperature is too high, it can be sealed in a plastic bag and then stored in the refrigerator.
When taking it out, do not open it immediately and allow it to slowly warm to room temperature before serving.
3. Fish. The fish in the refrigerator should not be stored for too long, the refrigeration temperature of the household refrigerator is generally -15, and the best refrigerator can only reach -20, and aquatic products, especially fish, when the storage temperature does not reach -30 below, the fish body tissue will be dehydrated or other changes, such as crucian carp refrigerated for a long time, it is easy to appear rancidity of the fish body, changes in meat quality, inedible.
4. Medicinal materials. Medicinal materials should not be placed in the refrigerator, the medicinal materials are put in the refrigerator, mixed with other foods for a long time, not only all kinds of bacteria are easy to invade the medicinal materials, but also easy to get damp, destroying the medicinal properties of the medicinal materials, so for some valuable medicinal materials, such as ginseng, deer antler, gastrodia, codonopsis, etc., if you need to store them for a long time, you can put them in a clean glass bottle, and then put in an appropriate amount of glutinous rice that is fried until it is dark yellow with a simmer, and put it in after cooling, seal the bottle cap tightly, and put it in a cool and ventilated place.
5. Tomatoes.
After the tomatoes are frozen at low temperature, the flesh is blister-like, soft and rotten, or there are spalling phenomena, there are black spots on the surface, undercooked, no umami, and in serious cases, it is rotten.
6. Cucumber and green pepper.
Cucumbers and green peppers will turn black, soft, and taste when stored in the refrigerator for a long time. Cucumbers also grow sticky hair. Because the storage temperature in the refrigerator is generally about 4 to 6, while the suitable storage temperature for cucumbers is 10 to 12, and green peppers are 7 to 8, so it should not be stored for a long time.
7. Bananas. If the banana is stored in a place below 12, it will make the banana black and rotten.
8. Fresh lychee.
If the lychee is left in an environment of 0 for one day, the skin will turn black and the flesh will become flavorful.
9. Strawberries. When strawberries are stored in the refrigerator, not only will the flesh be foamy and the taste will be greatly reduced, but they will also be susceptible to mildew.
10. Green leafy vegetables.
Leafy greens not only spoil the leaves faster when they are kept in the refrigerator, but they may also produce toxic nitrites due to enzymes and bacteria.

Some tropical fruits, such as bananas, mangoes, etc., are not suitable for putting in the refrigerator, because the temperature of the refrigerator is too low, the temperature of the general refrigerator is between 0 and 6 degrees, which will "frostbite" the fruit, that is, some friends will say that bananas are put in the refrigerator for two days, and there are many small black spots on the skin, as well as mangoes, and mango will also appear black spots on the mango peel for a few days in the refrigerator, which will not only accelerate the decay, but also the taste of the pulp will change, affecting the taste, and the best storage method is generally Put it in a cool and dark place.
Some friends often put chocolates in the refrigerator, including me, who didn't know before, but now I know that I will never put them again.
You will find that after the chocolate is put in the refrigerator for a period of time, when you take it out again, there will be a layer of hoarfrost on the surface of the chocolate, which is the ** I took above, which is the sugar in the chocolate absorbs the water, and then the water evaporates and leaves the sugar crystals, which will affect the taste of the chocolate, and it will become rough and not silky, so the best storage temperature for chocolate is between 12 and 18 degrees, and it is stored in the dark.
In fact, these baked foods are not suitable for putting in the refrigerator, and they will not play the role of preservation, but will absorb moisture and accelerate deterioration.
Some friends will also put honey in the refrigerator, in fact, honey itself has a strong ability to keep fresh and preservative, generally stored at room temperature, if you put it in the refrigerator, honey will crystallize and agglomerate, it is difficult to take out, and it will also affect the taste, either put it in a container and seal it again, or it is recommended to store it at room temperature, generally honey will not deteriorate for two or three years.
Most people's habit is to freeze the fish, the fish can not be frozen for too long, because the minimum temperature of the general refrigerator freezer is minus 15 to 20 degrees, and aquatic products, especially fish, must be stored at minus 30 degrees, so that the fish tissue will not be dehydrated, or other changes, if you put it for too long, the fish will deteriorate, affecting the taste, so don't put it for too long.
Red wine should not be put in the refrigerator for too long, because the best storage temperature of red wine is about 12 degrees, constant temperature is appropriate, do not alternate between hot and cold, and the temperature of the refrigerator is not constant, the working principle of the refrigerator is intermittent, the temperature changes repeatedly, will damage the quality of red wine, affect the taste, the humidity in the refrigerator is also large, and it is not conducive to the preservation of cork, so it is best to store unopened red wine in an environment of about 12 degrees.

Don't put these foods in the refrigerator, they are very harmful to your body after eating! Regret to know.
-
What kind of food should not be put in the refrigerator? Well, it's the food that can't be passive. Well, for example, it's better not to put some vegetables that have been fried in the refrigerator, because there are a lot of bacteria in the refrigerator, so if you fry it and put the ingredients in it, a lot of things will stick to it, and it will be very unhygienic to eat.
-
There are many foods that should not be put in the refrigerator, such as mangoes, bananas and tomatoes. Pasta and steamed buns should not be put in the refrigerator.
-
1.Honey; 2.Chocolate; 3.Some tropical fruits such as mangoes, bananas, papayas, avocados, passion fruits, etc.
-
Things that should not be put in the refrigerator are:
1) Bananas: Stored in an environment below 12 will make them black and rotten.
3) Cucumber: If you leave it in the refrigerator for three days, the skin will become water-soaked and lose the flavor it holds.
4) Tomatoes: After freezing, some or all of the fruits will be soaked in water and soft and rot, showing brown round spots.
It is better not to put bread in the refrigerator: the starch straight chain part of the flour has aged during the baking process, which is why the bread develops an elastic and soft structure. As the bread is left for a longer period of time, the amylopectin in the bread slowly associates, and the soft bread gradually hardens, a phenomenon called "aging".
The rate at which "aging" is temperature dependent. It ages faster at low temperatures (above the freezing point), while bread hardens faster when it is stored in the refrigerator.
Cucumbers and green peppers should not be stored in the refrigerator for a long time: If green peppers are stored in the refrigerator for a long time, they will have frostbite "injury" - blackening, softness, and taste. Cucumbers also grow sticky hair.
Because the temperature stored in the refrigerator is generally about 4 to 6, while the suitable storage temperature for cucumbers is 10 to 12, and green peppers are 7 to 8. Therefore, it is not suitable to exist for a long time.
Another place to be clear is that the principle of storing food in the refrigerator is to slow down the growth and reproduction of microorganisms, and cannot kill microorganisms. The most suitable reproduction temperature for most microorganisms is around 37 degrees Celsius, and some can multiply rapidly above 20 degrees Celsius, although the vast majority of microorganisms grow slowly below 10 degrees Celsius, but there are still some bacteria that can survive or even multiply at lower temperatures.
Therefore, inappropriate storage temperature, high food temperature, raw and cooked cross-storage, etc., all affect the refrigeration effect and reduce the "insurance coefficient" of the refrigerator.

Tropical fruits are not suitable for refrigerator storage.
-
Are there some foods that can't be put in the fridge?
-
Bananas and lychees in the refrigerator will accelerate spoilage, bread and cakes in the refrigerator will accelerate drying, and chocolate in the refrigerator for a long time will also cause a bad taste.

Dragon fruit, mango, lychee, longan, papaya, rambutan, banana, etc. are all very popular. However, once these fruits are put in the refrigerator after being bought, dark spots begin to appear within a few days, and most of them are more sensitive to cold and are not suitable for refrigeration. The peel is dented and some black-brown spots appear, indicating that the fruit is frostbitten.
Frostbitten fruits are not only destroyed in nutrients, but also spoil easily. After a few more days, the flesh turns brown in color and begins to rot, and such fruit is often no longer edible.
Tropical fruits are best stored in a cool place away from light, and if they must be placed in the refrigerator, they should be placed in a warm trough of vegetables and fruits, and the storage time should not exceed two days. Some tropical fruits that are not ripe when they are bought, such as bananas that are blue in color, are less cold-tolerant, so it is best not to put them in the refrigerator for Chinese dishes. Green leafy vegetables are easy to wilt, to keep it fresh, putting it in the refrigerator is indeed a way, but the temperature of the refrigerator is best controlled between 0 4 degrees Celsius, and then put a fresh-keeping bag outside, or put it in a fresh-keeping box for storage, in order to achieve the fresh-keeping effect.
Remember not to wash it before storage, and it should not be left for too long, otherwise the dish will be easy to rot.
Tuber vegetables like potatoes, cucumbers, carrots, etc., are not so squeamish, and they can be stored at room temperature and do not need to be kept in the refrigerator. It is important to note that tomatoes are not suitable for refrigerator storage. Because after the tomatoes are frozen at low temperature, the flesh will be blister-like, the umami will disappear, it is not easy to cook, and in severe cases, it will be rancid and rotten.
Chocolate should also not be kept in the refrigerator.
-
As far as I know, cut watermelon, peaches, leeks, etc., are those fruits and vegetables that are easy to skewer, and they are not easy to put in the refrigerator, in fact, I also think that any fruits and vegetables should not be stored in the refrigerator for a long time.

1. Bananas: If you put them in the refrigerator, they will turn black and taste bad. 2. Bread:
The loss of moisture will affect the taste, and it is best not to store it in the refrigerator during the season when it is not easy to get moldy, and it must be stored in the freezer when it is placed in the refrigerator. 3. Eggs: If you put eggs in the refrigerator, they will absorb the flavor in the refrigerator, and the eggs will be damaged.
4. Mayonnaise: Mayonnaise is easy to decompose below 9 degrees, and fungi are easy to multiply, so it is best to store it at room temperature. 5. Potatoes and turnips:
If the potatoes are stored in the refrigerator, they will greatly affect the taste, so they should be stored in an indoor without sunlight. If the radish is kept in the refrigerator for a long time, the color and taste will be affected. 6. Carrots and tofu:
If the carrot is stored in the refrigerator, the moisture in it will freeze, which will affect the texture and lose nutrients. Tofu is best to eat immediately after purchase. 7. Canned food:
When canned food is made, it is made for long-term preservation, so it doesn't make sense to keep it in the refrigerator. After opening the can, the remaining contents are stored in other containers. 8. Tomatoes:
After the tomatoes are frozen at low temperature, the flesh is blister-like, soft and rotten, or there is a phenomenon of spallation, there are black spots on the surface, undercooked, no umami, and in serious cases, it is rancid and rotten. 9. Ham: If the ham is stored in the refrigerator at low temperature, the moisture in it will freeze, the fat will precipitate, the leg meat will clump or loose, the meat will become tasteful, and it is easy to spoil.
10. Chocolate: After the chocolate is frozen in the refrigerator, once it is taken out, a layer of hoarfrost will form on its surface at room temperature, which is very easy to mold and deteriorate and lose its original taste. 11. Cucumber, green pepper:
Cucumbers and green peppers that have been stored in the refrigerator for a long time will cause frostbite "injury" - blackening, softness, and flavor change. Cucumbers also grow and are sticky. Because the temperature stored in the refrigerator is generally about 4 to 6, while the suitable storage temperature for cucumbers is 10 to 12, and green peppers are 7 to 8.
Therefore, it is not suitable to exist for a long time. 12、.Fresh lychee:
If the fresh lychee is left in an environment of 0 for one day, the skin will turn black and the flesh will become flavorful. Most tropical fruits such as dragon fruit, mango, lychee, longan, papaya, and rambutan are afraid of cold and should not be refrigerated in the refrigerator. Frostbitten fruits are not only destroyed in nutrients, but also spoil easily.
After a few more days, the flesh will rot.

Don't leave anything for too long, because the food stays in the refrigerator for a long time, and a substance in the refrigerator is not good for the food, which will make the food not fresh, and eating too much will cause a stomachache. This is because a substance in the refrigerator stains the food with bacteria. Therefore, if the same thing is going to be left for too long, it is recommended to put plastic wrap or put it in the freezer. >>>More
