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: When frozen, they will be soaked in water and soft and rotten, with brown round spots. Bread should not be put in the refrigerator.
During the baking process of bread, the starch linear parts in the flour have aged, 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.
When green peppers are stored in the refrigerator for a long time, they will have frostbite "injuries" - blackening, softness, and flavor change. 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.
As we all know, in daily life, the use of refrigerators provides great convenience to people. But there is still such a phenomenon, the dishes just made at night, not finished, put in the refrigerator to refrigerate, and then eat after heating the next day, actually have diarrhea, what is the reason?
In fact, the principle of storing food in the refrigerator is to slow down the growth and reproduction of microorganisms, but 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.
The refrigerator compartment temperature is generally 4 -10. Meals are taken out of the refrigerator and heated immediately, which requires a gradual heating process, from 4 -40 is just the appropriate temperature for bacteria to multiply, and gradual heating is equivalent to creating a good environment for bacteria to multiply.

Yes, you can, refrigerate, don't freeze it, but you can also eat tomatoes with ice in the freezer before eating.

Tomatoes should not be kept in the refrigerator for refrigeration. Tomatoes have loose cells inside, thin cell walls, and more free water. The cells in the refrigerator are prone to freezing and swelling, causing the cells to burst and deteriorate.
If the tomatoes are left in the refrigerator for a few days, there will be dark spots on the surface, and the endoplasm will blister or peel. Tomatoes at this time not only do not have umami, but also taste very poor and lose their nutritional value. Such tomatoes cannot be eaten and can seriously cause bacterial food poisoning.
After buying it, wash it, dry the surface, choose a large bottle, cut the tomatoes into cubes, put the bottle in the steamer and cook for 20 minutes, close the lid with heat, take it out to cool, and then store it in a cool place, and take it out again when the vegetables are scarce. Cooking and soup are very good choices. It tastes good.

Tomatoes should not be kept in the refrigerator. Once the tomatoes are stored in the refrigerator at low temperature, they will lose their original umami, and the flesh quality will also change significantly, if it is blistered for a long time, and it should not be cooked when cooking, and some will rot, so tomatoes are not suitable for refrigeration and preservation. Tomatoes are stored in the refrigerator for a longer time, and nutrients will be lost more.
Tomato preservation explainedDry tomatoes into a plastic bag, add cold water to the basin, drain the air in the bag, put it into the water, squeeze the air that has not been squeezed out, tie the bag tightly, and then put it into the water to soak, so after processing, it is equivalent to the tomato in a vacuum environment, you can avoid deterioration and rot, but during the preservation period, you should look at it every few days, if there is water on the surface of the tomatoes, you need to take it out and dry it, and replace the bag, which can be stored for a long time, and it will not rot for a month.

Tomatoes don't always last long. Learn this trick, it's simple and practical! It's summer, but it's getting hotter and hotter, and it's getting harder and harder to keep food at home.
Lots of friends like it. Foods that are often eaten are kept in the fridge, but there are many things that are not suitable for storage in the refrigerator, including tomatoes, which many of us love to eat. Today's little girl is here to tell you why they are not suitable for storage in the refrigerator.
First of all, when the tomatoes are left at a low temperature for a while, the flesh will become soft and rotten. If the temperature is too low, black spots and blisters may appear, and in some cases, it will rot. The second is that tomatoes can easily lose their original flavor when kept in the refrigerator.
Whether we eat them raw or boiled, they lose their original sweet and sour taste. Today's little girl will tell you how to keep tomatoes fresh. Because many friends often ask Bian Xiao in private that tomatoes cannot be stored for a long time, and then, today Bian Xiao teaches you this trick, which is very simple and practical.
Let's take a look. What we need to know is to prepare a clean plastic bag, in good condition, and a basin of water, and turn the tomatoes upside down. Put it in a plastic bag.
At this time, it is important to note that tomatoes are placed head-down. Otherwise, tomatoes are easily ripe. Then we put the tomatoes in the water, and then squeeze out the air inside the plastic bag to make the plastic bag into a vacuum.
We tie the plastic bag tightly so that the tomatoes are kept in a vacuum. Then, this prevents the tomatoes from coming into contact with the air, but if you put them in water, it gives the tomatoes a room temperature environment, because there are a lot of places that summer. Its temperature has directly exceeded 30 degrees Celsius, so it is directly beyond the normal temperature range, so I have to use this method.
All we have to do is put this basin in a cool place and change the water every two days. In this way, the tomatoes will be fresh for half a month. After that, it's time for the tips to save tomatoes that Riko will share with you.
Didn't you learn? Really practical.

Tomatoes should not be put in the refrigerator.
After the tomatoes are frozen at low temperature, the flesh is blister-like, soft or spalled, there are black spots on the surface, undercooked, no umami, and in serious cases, they are rancid and rotten. Therefore, tomatoes should not be kept in the refrigerator.
Unlike other fruits, tomatoes are not suitable for low temperature storage, the reason why this is so is because in a low temperature environment, tomatoes are easy to be frozen, and the skin of tomatoes will be frozen and cracked at low temperatures, which will cause tomatoes to deteriorate and become soft and rotten, and the longer they are stored in a low temperature environment, the easier it is to cause the loss of nutrients in tomatoes.
Tomato buying tips
1. Pick the tomatoes and look at their color. Generally speaking, the redder the tomatoes, the better they taste. Of course, this red is a natural red, not an artificial redness.
Since the redder the tomato, the higher its ripeness and the less fully developed it is, so the nutrition and taste can keep up. Of course, pale red tomatoes are also good to eat, if you like to eat them with a more sour taste.
2. Select tomatoes and look at their appearance. If the shape of the tomato is round and slightly elastic, this type of tomato is not only fresh, but also has a better taste. If you come across a prismatic shape or a spot on the skin, the quality will be greatly reduced.

Cucumber. Reasons why tomatoes can't be put in the refrigerator:
After the tomatoes are frozen at low temperature, the flesh is blister-like, soft or spalled, there are black spots on the surface, undercooked, no umami, and in serious cases, they are rancid and rotten.
Cucumbers and refrigerators that are stored for a long time will cause frostbite to turn black, soft, and tasteless. Cucumbers also grow and are sticky. Because the storage temperature in the refrigerator is generally about 4 to 6, and the suitable storage temperature of cucumbers is 10 to 12, it is not suitable for long-term storage.
Note: It's not just these two foods that don't fit in the fridge for storage, but also fruits. Mangoes, persimmons, bananas and other jam fruits.
The so-called sauce fruits are those fruits that can be peeled and the flesh is paste-like, and berry fruits will lose their flavor and deteriorate the skin under low temperature conditions. For example, we all know that bananas are easy to turn black and rot when placed below 12, and fresh lychees will turn black and the flesh will change flavor if left in an environment of 0 for a day. Citrus fruits such as oranges, lemons, and oranges, in the case of low temperatures, the oil from the skin is easy to penetrate into the pulp, and the flesh is easy to bitter, so it is not suitable to put it in the refrigerator, and citrus fruits are best stored at room temperature of about 15 degrees.
Like strawberries, bayberry, mulberry.
Ready-to-eat fruits are best bought and eaten immediately, as putting them in the refrigerator will not only affect the taste, but also be easy to mildew.

Cucumbers and tomatoes are vegetables that we often use in our daily life, but they have a relatively short shelf life and are susceptible to spoilage due to the influence of the external environment. So, is putting cucumbers and tomatoes in the fridge effective in extending their shelf life?
First of all, we need to understand the characteristics of cucumbers and tomatoes. Cucumber is a vegetable with a high moisture content that is susceptible to softening or spoilage due to water evaporation or excessive moisture; Tomatoes, on the other hand, are a vegetable rich in vitamin C and carotene, but their surface is easily damaged by friction or pressure, resulting in bacteria easily invading and accelerating spoilage.
Secondly, we need to understand the characteristics of the refrigerator. The temperature in the refrigerator is lower than room temperature, which can effectively slow down the metabolism of food and thus prolong the freshness of food. However, due to the low humidity in the refrigerator, cucumbers and tomatoes tend to lose their moisture marks, causing them to become dry, weak, and have a poor taste.
Based on the above characteristics, we can conclude that cucumbers and tomatoes can be kept fresh in the refrigerator, but the following points need to be noted:
1.Cucumbers and tomatoes should be placed separately so that they do not affect each other and cause spoilage;
2.Cucumbers and tomatoes should be placed away from the air conditioning outlet to avoid being affected by too much cold air and losing moisture;
3.Cucumbers and tomatoes should not be left for too long, and it is best to eat them within 1-2 weeks so as not to lose their nutritional value and taste.
In conclusion, putting cucumbers and tomatoes in the refrigerator can effectively extend their shelf life, but you need to pay attention to the location and time to avoid affecting their nutritional value and taste.

1. Tomatoes and cucumbers can be kept fresh in the refrigerator;
2. Tomatoes can be stored in the refrigerator, but the storage time should not be too long. If tomatoes are left in the refrigerator for too long, they will appear dark spots or rot on the surface. Tomatoes can also be placed with the fruit pedicle facing down and stored indoors in a cool place.
3. Cucumbers should be stored in the refrigerator. The temperature in the refrigerator is generally around 4°C to 6°C, while the suitable temperature for cucumber storage is 10°C to 12°C. Due to the high water content of cucumbers, if they are refrigerated for a long time, they will cause frostbite, blackening, softness, and flavor.
You can wrap the cucumber in plastic wrap and put it in the fresh-keeping room of the refrigerator, generally for 1-2 days.

Hello dear, you can try the following first step: add an appropriate amount of water to the pot, about the cucumber and tomatoes, add a spoonful of salt, and then stir to melt. Step 2:
Soak cucumbers and tomatoes in water for about 10 minutes, at which point you will notice that there are many small bubbles attached to the cucumbers and tomatoes, which can continue to maintain the metabolic activity of cucumbers and tomatoes. Keep cucumbers and tomatoes fresh and not spoiled. Step 3:
Remove the cucumbers and tomatoes without controlling the moisture, then put them in a plastic bag and store them in a cool place. Salt water can prevent the water in cucumbers from being lost, and it can also prevent the reproduction of microorganisms, so that cucumbers and tomatoes can be kept fresh for about 20 days. I hope mine can help you.

Yes, it is generally not recommended to put it in the refrigerator. Tomatoes in the refrigerator can easily cause frostbite due to low temperatures, which will make the flesh blister-like or split, and become very soft and rotten, and there is no umami, so it is not recommended to store tomatoes in the refrigerator.
Tomatoes contain a lot of acids and sugars, and if they are left in the refrigerator for a long time, these substances will be destroyed and the nutrients of tomatoes will be lost.
Tomatoes are nutritious, sweet and sour, and can be eaten raw, cold or fried, making them an indispensable dish on the table.
Fresh tomatoes can be put into plastic food bags, tied tightly, and stored in a cool place at room temperature, which can generally be stored for about 5 days.
Fresh blueberries need to be stored at a temperature of less than 10 percent, even during transportation. However, the fruit must go through a pre-cooling process to remove the heat from the field to effectively prevent rotting. The main methods of pre-cooling are vacuum cooling, cold water cooling, and cold air cooling. >>>More
