Now every household has bought a refrigerator, which can help us a lot, such as keeping fresh the fruits and vegetables we just bought and putting leftovers that some people can't finish, for fear of waste. Can these be put in? Does eating affect your health? Let's take a look at the fruits and vegetables suitable for the refrigerator.

Fruits and vegetables suitable for refrigerator 1 can be stored in the refrigerator:

① Fruits: Except melons, oranges and bananas, all kinds of fruits should be put in separate drawers in the refrigerator, separated from vegetables. Don't wash it too early when you buy it home, because too much water will accelerate the decay and deterioration of fruits. It is best to keep the whole lemon at room temperature, but the cut lemon should be kept in the refrigerator.

2 leafy vegetables are easy to wilt when stored at room temperature. To keep leafy vegetables fresh, you can put them in the refrigerator. However, it is best to control the temperature of the refrigerator between 0-4℃, do not clean it before storage, put a fresh-keeping bag outside, or store it in a fresh-keeping box to achieve the effect of fresh-keeping.

(3) If peaches and apples are freshly picked, it is best to leave them at room temperature for half a day to a day, and then wrap them in kraft paper or wrap them in plastic wrap and put them in the refrigerator to avoid affecting the taste.

4 persimmon peppers, etc. The suitable storage temperature is between -2℃ and 65438 00℃. The lowest suitable temperature of this kind of fruits and vegetables is -2℃, which can be stored in the refrigerator, but it is not suitable for a long time, only suitable for two or three days.

⑤ The storage temperature of vegetables is about 0℃, such as Chinese cabbage, lettuce, spinach, celery, cauliflower, onion, cabbage, carrot, peach, grape, apple, strawberry and so on. This kind of fruit and vegetable can be safely stored in the refrigerator, and it doesn't matter if it is kept for a few more days.

Can't be stored in the refrigerator:

Garlic, onion, ginger and pepper are mostly condiments, so it is best to keep their original appearance when preserved. Garlic is preserved in a similar way to onion. It can be placed in a net bag and hung in a cool and ventilated place indoors, or it can be placed in a special ceramic cylinder with air holes.

2 Cucumber and green pepper: Cucumber and green pepper will freeze and "hurt" if they are put in the refrigerator for a long time-turn black, soften and taste bad. Cucumbers also have sticky hairs. Because the temperature of refrigerator storage is generally around 4℃ to 6℃, the suitable storage temperature of cucumber is 10℃ to 12℃, and the suitable storage temperature of green pepper is 7℃ to 8℃. So it shouldn't last long.

③ Some tropical fruits, such as bananas, pineapples, papayas and mangoes. There is a relatively high optimum storage temperature, so there is no need to put them in the refrigerator. As long as it is kept in a cool place at room temperature. If the storage temperature is too low, the peel will droop or produce spots or browning. Bananas, for example, will soon turn black in the refrigerator.

④ Cucumber: The suitable storage temperature of cucumber is between 10 ~ 12℃. If you put the cucumber in the refrigerator and soak the skin in water within three days, the unique flavor of the cucumber will be lost.

⑤ Medicinal materials: Perilla, celery, coriander and other medicinal materials should be preserved in the same way as flowers, and the stem ends should be trimmed and put into water bottles. Cover it loosely with a plastic bag, which will keep it fresh for at least a week.

Fruits and vegetables suitable for refrigerator 2. Green leafy vegetables wither easily. To keep them fresh, it is indeed a way to put them in the refrigerator, but it is best to control the temperature of the refrigerator between 0 and 4 degrees Celsius, put a fresh-keeping bag outside or keep them in a fresh-keeping box, so as to achieve the effect of fresh-keeping. Remember that it is best not to wash before storage, and the storage time should not be too long, otherwise the dishes will be easily covered.

Tuber vegetables, such as potatoes, cucumbers and carrots, are not so delicate. Just keep it at room temperature, there is no need to put it in the refrigerator. It should be noted that tomatoes are not suitable for storage in the refrigerator. Because tomatoes are frozen at low temperature, the meat will bubble, the umami will disappear, it is not easy to cook, and it will be rancid and rotten in serious cases. )

Mango, persimmon, banana and other jam fruits.

The so-called jam fruits are those fruits that can be peeled and have jam-like pulp. Berry fruits will lose their fragrance and their skins will deteriorate at low temperature.

For example, we all know that bananas are easy to turn black and rot when placed below 12℃, and fresh litchi will turn black and taste when placed at 0℃ for one day. Citrus fruits, such as oranges, lemons and oranges. It is easy to penetrate into the pulp at low temperature, and the pulp will be bitter, which is not suitable for refrigerator. Citrus fruits are best stored at room temperature around 15 degrees.

Instant fruits, such as strawberries, bayberry, mulberry, etc. , it is best to buy it immediately. Putting them in the refrigerator will not only affect the taste, but also easily mildew. Apples and watermelons can stay in the refrigerator for a short time to extend the shelf life.

The suitable storage temperature of Chinese cabbage, celery, onion and carrot is about 0℃.

The suitable storage temperature of cucumber, eggplant and tomato is between 7.2 ~ 10℃.

1, tomato

After being frozen at low temperature, tomatoes are blistered, soft, rotten or cracked, with dark spots on the surface, tasteless and sour.

I remind you: six points to pay attention to when storing food in refrigerator.

1, hot food must not be put into the running refrigerator.

2. The food should not be too full or too tight, and there should be a gap to facilitate cold air convection, reduce the load of the unit, prolong the service life and save electricity.

3. Food should not be mixed raw and cooked to maintain hygiene. According to the requirements of food storage time and temperature, the space in the box is reasonably utilized. Don't put the food directly on the surface of the evaporator, but put it in a vessel to avoid freezing on the evaporator, which is inconvenient to take out.

Fresh fish and meat should be packed in plastic bags and then stored in the refrigerator. Vegetables and fruits should be dried on the outer surface, placed at the bottom of the box and stored at zero temperature.

5. Bottled liquid drinks should not be put into the freezer to avoid freezing and cracking the packaging bottles. It should be stored in the refrigerator or on the door, preferably at around 4℃.

6. Refrigerators that store food should not store chemicals at the same time.

2. Fresh litchi

When fresh litchi is stored at 0℃ for one day, the peel turns black and the pulp turns sour.

3. Chocolate

Once the chocolate is put in the refrigerator, once it is taken out, it will form a layer of frost on its surface at room temperature, which is easy to go moldy and deteriorate and lose its original flavor.

Tip: In many families, the refrigerator has almost become a "safe" for food. Whether it is raw or cooked, vegetables or meat, as long as you throw it into the refrigerator, you will feel that everything is fine and the food quality is guaranteed. In fact, refrigerators have many kinds of "sins" of "dereliction of duty" when they cheat people's trust.

Breeding bacteria: In a low temperature environment, the metabolism of food itself will only slow down and will not stop. Most bacteria don't die of low temperature. On the contrary, many microorganisms grow and reproduce easily at low temperature. At the same time, the high humidity in the refrigerator is not conducive to food preservation.

Stealing nutrition: the refrigerator is the "black hand" to steal food nutrition, especially those vegetables and fruits rich in vitamins. Studies have confirmed that the vitamin C content of cucumber will be reduced by 30% when stored in a refrigerator at 4℃ for 24 hours.

Destroy delicious food: refrigerator is the killer of delicious food. Fresh bread, fresh and attractive bananas and lychees, as well as bean paste, ham and canned meat with unique flavor, often lose their color and taste after being put into the refrigerator, and some peculiar smells will be absorbed if they are not done well.

Refrigerator disease: The food directly taken out of the refrigerator will lead to rapid contraction and spasm of gastric mucosal blood vessels, causing stomach discomfort and even stomach diseases, while those microorganisms that breed in a low temperature environment will cause acute enteritis and even dysentery. Yersinia enteritis is called "refrigerator enteritis", which can survive and reproduce at a low temperature of -40℃, and the refrigerator is their paradise.

Hiding evils and accommodating filth: No matter raw or cooked, no matter what kind, all kinds of food and harmful chemicals produced by the decomposition of food itself, tea, coffee, tobacco, cosmetics and even films all gather in the refrigerator, carrying various smells, producing thousands of bacteria and fungi in Qian Qian, and the refrigerator has gradually become a place to hide evils and accommodate filth.

Making poison: Many people like to buy in bulk and store vegetables in the refrigerator within a week. This practice is very dangerous. Vegetables originally contain nitrate, which will form nitrite under the action of nitrate reductase. This substance is toxic and will lead to lack of oxygen. Vegetables cooked in the refrigerator are also producers of nitrite. The leftovers that people eat are polluted by bacteria and enzymes in saliva, and nitrite forms faster.

4. Ham

When ham is stored in the refrigerator at low temperature, the water will freeze, the fat will precipitate, the leg meat will agglomerate or loosen, and the meat will become stale and perishable.

5.bananas

Bananas will turn black and rot if stored below 12℃.

Here are four ways to keep food fresh in the refrigerator.

Three refrigerators are ideal: the one in the kitchen is used to store food for a short time, the one in the study is used to store cigars, films, medicines and cosmetics, and the one in the living room is mainly used to refrigerate all kinds of drinks, tea, fruits and desserts. If there is only one refrigerator, it is necessary to know the temperature difference of the refrigerator space.

Vegetables and fruits are suitable to be placed in the storage box at the lower part of the cold storage room with low temperature and high humidity; The optimum storage temperature of milk, beer and fruit juice is 2 ~ 6℃. Those fish eaten within 1 ~ 2 days should be kept in an ice greenhouse at 0℃. The meat recently eaten is suitable for freezing at -7℃, and the food does not need to be thawed to prevent nutrient loss.

Plastic wrap has many uses: after buying fresh fruits and vegetables, remove dirt and yellow leaves, immediately wrap them in plastic wrap and put them in the refrigerator.

This has four advantages:

The first is to reduce external pollution sources.

The second is to protect vitamins in vegetables and fruits.

The third is to prevent the aromatic odor from escaping and causing other foods to taste bad.

Fourthly, the contact with oxygen is reduced, which is beneficial to preservation.

Food entering the freezer is afraid of repeated freezing and thawing, because freezing and thawing will destroy the structure of cells, increase the chance of corruption and affect the taste of food. Therefore, it is necessary to repackage the food roughly according to the consumption each time, wrap it in thick and dry plastic bags and put it in the freezer.

Clean medical alcohol: You can clean the refrigerator regularly with medical alcohol and clean gauze. 75% alcohol can effectively kill all kinds of microorganisms, dissolve and remove some stains attached to the refrigerator wall. Alcohol is volatile and will not leave odor after cleaning like other commonly used chlorine-containing disinfectants.

Avoid the "second entry" of food: when taking food from the refrigerator, think about the variety and dosage in advance. Try not to put leftovers back in the refrigerator, avoid handling a lot of food in advance and store them in the refrigerator. This will not only destroy the nutritional value of food, but also increase health risks.

Fruits and vegetables suitable for refrigerator 3. These things had better not be put away.

Anyone who drinks Chinese medicine at home and uses Chinese medicine for health and diet should pay attention to it: it is best not to store Chinese medicine in the refrigerator. Storing the medicine in the refrigerator will not only affect the efficacy of the medicine, but also cause the medicinal materials to be contaminated by bacteria in the refrigerator, which is harmful to health! In particular, the "precious supplements" such as ginseng, velvet antler and bird's nest at home are really not worth the candle.

If you want to store it, just ventilate it at room temperature ~

Naked leftovers

Of course, it is ok to put the leftovers in the freezer of the refrigerator, but if the leftovers are put naked in the freezer of the refrigerator without a cover, not only the food is prone to odor, but also the risk of cross-infection of bacteria in the refrigerator will be increased.

Leftovers should be put in a sealed fresh-keeping box, or covered with plastic wrap and put in the refrigerator. Not only is it not easy to go bad, but it can also ensure that you will not eat bad stomach to a great extent.

All leafy vegetables

All leafy vegetables, including Chinese cabbage, water spinach and lettuce, are not suitable for storage in the refrigerator. After leafy vegetables are put in the refrigerator, they are easy to get frostbite and have a bad taste. Moreover, after the leafy vegetables are frozen, they will soon produce an unpleasant smell in the refrigerator, which will affect other foods in the refrigerator. Therefore, after buying leafy vegetables, it is best to cook and eat them now, and don't leave them for too long, otherwise the taste will be particularly affected.

If you want to store leafy vegetables, the best storage temperature is about 0 to 4 degrees. According to the recent temperature, just put it in a ventilated and dry place in the kitchen ~

Most fruits

All tropical fruits, including bananas, litchi, papaya and other fruits, as well as tomatoes, cucumbers and other vegetables, are not suitable for long-term storage in the refrigerator. Bananas are easy to deteriorate, turn black and rot in the refrigerator, which is shorter than the shelf life of bananas that can be preserved at room temperature. Tomatoes are easily frozen and softened in the refrigerator.

Apples, peaches, oranges, kiwis and other fruits don't need to be put in the refrigerator. Sealed, non-perishable healthy fruits can be stored for about 15-30 days even if they are not stored outdoors in the refrigerator. If stored in the refrigerator, it may be contaminated by bacteria in the refrigerator, which may be more prone to deterioration.

There is only one case where fruit needs to be put in the refrigerator.

Fruit that has been cut but not eaten.

This kind of fruit can be stored in the refrigerator for the purpose of keeping fresh and avoiding deterioration, but plastic wrap and plastic bags must be used to prevent the fruit from being exposed and corroded by bacteria in the refrigerator. And eat as soon as possible, or you will definitely have diarrhea.
