Overnight vegetables, overnight water, overnight meat and overnight eggs, which one can you eat? It's not too late to know now

Since ancient times, the Chinese have advocated frugality and regarded frugality as an excellent traditional virtue. As our living standards gradually improve, many families still stick to this good idea and will save as much as possible.

(overnight dish)

In life, this concept of thrift may run through all aspects of diet. Just like when we cook, we often carefully calculate the ingredients and try to live within our means. And now, when we eat together, we have a disc awareness, and if we can’t finish it, we choose to take it away. But these packaged dishes are often eaten the next day, turning them into overnight dishes.

Can overnight dishes be eaten? It is closely related to its type and storage conditions, and it is divided into two types here.

Green leafy vegetables

Many green leafy vegetables contain high amounts of nitrates. After frying at high temperature, a large amount of nitrate will become nitrite. If left for a long time, the vegetables will be infected with bacteria, resulting in more nitrite.

Nitrite cannot be converted to nitrate when reheated. This kind of nitrite has a carcinogenic hazard, so vegetables must not be eaten overnight.

other vegetables

For example, tomatoes, potatoes, and other vegetables can continue to be eaten after they are fully reheated the next day. Although the nutrition will be reduced, there is no major harm.

However, if it is a cold dish, the ingredients themselves are not heated at high temperature. After a long time of storage, if you eat it without heating, there are certain hidden dangers, which may cause abdominal pain, diarrhea and other phenomena, so you need to pay attention.

overnight meat

Meat dumplings contain less nitrate and are highly safe. The main problem is that raw meat is more suitable for bacterial growth, and raw meat carries more bacteria.

If it is kept at the fresh temperature of the refrigerator, a large number of bacteria will grow in raw meat after a few days, so the most effective way is to buy a small amount of meat at a time and put it in the refrigerator as much as possible to prevent the growth of bacteria.

If it is fresh meat stewed by oneself, it will not produce too many harmful substances. As long as it is stored properly and heated thoroughly during cooking, the harmful substances produced will not threaten human health.

However, industrially processed meat generally contains preservatives. The most commonly used preservative is sodium nitrite. The legal use of sodium nitrite will not cause harm to the human body, but if the source is unknown, excessive use is more dangerous.

overnight water

Generally speaking, whether the overnight water can be drunk or not depends on the storage time and environment and has little to do with the overnight itself. The content of nitrite in the water is less and will not cause cancer.

Overnight water is mainly affected by objective factors such as environment, temperature, and sanitary conditions. For example, in summer, the ambient temperature is high, and the bacteria multiply quickly for more than 8 hours, and it is easy to be polluted by bacteria in the air, and it is easy to cause gastrointestinal inflammation after drinking.

Therefore, if the raw water quality is clean and meets hygienic standards, whether it is overnight water or long-term water during the day, if it can be preserved and free from dust, bacteria, etc., you can drink it with confidence.

overnight eggs

Take boiled eggs, for example. The answer depends on the situation. If the eggs are boiled, the salmonella may not be completely killed. After a period of time, bacteria may multiply a lot, so it is best not to eat boiled eggs overnight.

There is also some knowledge about the temperature at which eggs are stored. If stored in a refrigerated environment, it can be used normally after overnight. However, if it is stored at room temperature, especially at a high temperature above 30 degrees, the eggs cooked in the morning may not be eaten at night, so it is not recommended to eat them.

Do these three things right to keep food safe overnight

●Low temperature preservation

Placed in a 4-degree refrigerator (refrigerated), it can inhibit the growth and reproduction of microorganisms, inhibit the activity of nitrate reductase, reduce the production of nitrite, and greatly reduce the production of nitrite.

●Reheat before eating

There are psychrophilic bacteria in the refrigerator, which is also the cause of food spoilage in the refrigerator. Therefore, food taken out of the refrigerator should be reheated twice before eating.

In addition, if it is fruits and vegetables, they should also be washed before eating. At the same time, the refrigerator should be cleaned regularly, and bad food should be thrown away as soon as possible. Maintaining a clean refrigerator environment is also conducive to food storage.

●Be sure to keep it sealed

Food put in the refrigerator must be sealed to reduce the chance of food being infected by bacteria. Although the temperature in the refrigerator is very low, it is not a disinfection cabinet, but there are still some bacteria that are resistant to low temperature.

Therefore, no matter what kind of food, it should be sealed before putting it in the refrigerator to prevent cross infection. Overnight dishes must be sealed before putting them in the refrigerator, which can block the probability of bacterial infection and reduce bad eating problems.
