An overnight meal refers to how long it takes, and an overnight meal refers to how many hours

How many hours does an overnight dish refer to.

Overnight dishes don't just refer to the part of the dinner that has been left overnight.

In fact, leftovers from the day, such as a meal made at 12 noon, can also be counted as an overnight dish by 20 pm. The same leftovers that have gone through 8 hours need to be treated equally. Otherwise, you may have eaten an overnight meal and you don't know it yet.

What are some overnight dishes that you can't eat?

1 Leafy greens?

Fertilizers and insect pesticides used to grow vegetables contain nitrate, and when green leafy vegetables are reheated, nitrate can easily turn into a carcinogen, nitrite.

After eating, nitrosamines, another carcinogen, are synthesized from proteins in the stomach.

Causes great damage to the body, especially dark green vegetables such as: spinach, nine-story tower.

Chinese cabbage, green cabbage....etc., may contain a lot of nitrates, so be especially careful when eating leftovers!

2 Meat, eggs and soups?

Meat and egg food is rich in nutrients, and it is also very easy to breed bacteria, and often we will make a little more of these foods and put them in the refrigerator, and then heat them up next time we eat them, in fact, this will not resist bacterial growth, especially hard-boiled eggs are more prone to bacteria, and soup foods can be covered with plastic wrap.

Wrap it up and store it, but it shouldn't be too long

3 Seafood?

Fish, shellfish placed for too long, it is easy to produce bacteria and toxins, if you add the protein degradant after overnight, there will be more damage to the liver and kidneys, it is recommended to eat as much as you thaw, if you buy too much at a time, use a fresh-keeping bag, fresh-keeping box, put it in the freezer, reduce the chance of eating the virus

4 Tremella, mushrooms?

Whether it is wild or cultivated white fungus, mushrooms, etc., it is easy to leave a lot of nitrates. If you put it for a long time, you can only throw it away, otherwise it may cause gastrointestinal discomfort

5 Lo-mei? Everyone usually braised pork.

Dry, braised pork, will cook a big pot before each meal and then take it out to heat it up, right, but have you noticed that the same pot of braised pork becomes saltier and saltier the more you eat, and the more white rice is served, this is because in the heating process, the water evaporates and leaves soy sauce, salt and sugar....Eating too much will not only make you fat, but also release nitrite in the process of repeated cooking, increasing the risk of cancer!

Overnight meals are generally meals made at night or noon, and leftovers or uneaten meals are eaten at night and are uniformly called overnight meals the next day.

How long should it be more than 12 hours?

An overnight dish is a dish that takes more than 8 to 10 hours.

Overnight vegetables are dishes that have been placed overnight, because some green leafy vegetables contain more nitrates, if they are left for too long after cooking, under the decomposition of bacteria, nitrate will be reduced to nitrite, and heating can not be removed.

According to scientific determination, some overnight vegetables, especially overnight green leafy vegetables, not only have their nutritional value destroyed, but also produce disease-causing nitrite. The amount of nitrite in stored vegetables increased with the extension of storage time and the increase of temperature, while the increase of nitrite was less if the vegetables were refrigerated in the refrigerator (2-6 degrees Celsius). And "overnight" is not the key to nitrite production, and heating does not increase carcinogen levels.

Of course, many kinds of vitamins in vegetables will be destroyed when heated, and vegetables that have been heated many times are more unpalatable. From the perspective of "delicious", "overnight dishes" are indeed poor; From a nutritional point of view, there is no benefit to reheating too often.

As long as it is more than 8 hours, it will be an overnight meal. In the leftover food, there will be a variety of viruses and bacteria that are harmful to human health, and the test found that although some leftover foods do not have pathogenic bacteria in them, they cannot eat leftovers for a long time, and once the environment changes, they will also produce pathogenic bacteria, which endanger human health.

In recent years, it is often said that eating overnight meals can cause cancer, because many people in life often do more when cooking, leaving leftovers, and losing them is also wasted, so many people put it in the refrigerator and save it, and eat it again the next day, but everyone does not know that eating overnight meals often is more harmful to the human body, so what is the harm of eating overnight meals?

An overnight dish is not only a dish that has been left overnight, but should be counted as an overnight dish if it is placed for more than 8 10 hours. There are two reasons for the increase in toxic components in food, one is that chemicals in food produce carcinogens, such as nitrite, which cannot be removed by heating. The second is that in the process of placement, foreign bacteria are contaminated twice.

There are two major safety problems in the nocturnal diet, one is the multiplication of microorganisms, which will cause food to spoil; Second, the increased nitrite content can cause food poisoning and is carcinogenic.

Just like the truth of overnight tea, tea belongs to the leaves, nitrate content is relatively high, but generally a cup of tea, to put 1-2 grams of tea, the total nitrate content is relatively small, the total nitrate in a cup of tea is only 6 mg, even if all converted into nitrite will not cause poisoning, overnight water toxicity is pure rumor, unfounded, fungus does contain more nitrate, but that is the number of dried products, after soaking, the nitrate content has become 1 10, far lower than the content of many leafy vegetables.

Still, overnight food is a higher threat to food safety than freshly cooked food. So, eat as fresh food as possible, and cut the leftover food into small pieces as long as it is well preserved. The best thing to do is to set it out at the end of cooking, cut the leftovers into small pieces, put them in a clean crisper box, and wait until the temperature is not hot before putting the leftovers in the refrigerator.

For fungus, if you soak too much at a time, as long as you change the new water and put it in the refrigerator, you can avoid the smell and smell, and you can continue to cook and eat it after washing it the next day; Regarding overnight water, pour a glass of boiled water the night before, just cover the cup to avoid dust in the air, and you can still drink it the next morning, but overnight tea will not cause poisoning, but because its fragrance and taste are not as good as new bubbles, there is a risk of microorganisms exceeding the standard, so it is best not to drink.

Under normal circumstances, stem and leaf vegetables have the highest nitrate content, melon vegetables are lower, and root and cauliflower are more. So, if you buy a lot of vegetables at the same time, first eat leafy vegetables, such as Chinese cabbage, spinach, etc. If you are going to cook more dishes that are hot the next day, you should try to make less stem and leaf vegetables and more melon vegetables.

Eating overnight seafood is harmful to the liver and kidneys.

Seafood, such as crabs, fish, shrimps, etc., will produce degradable proteins overnight, damaging liver and kidney function. If you do buy too much, you can put the raw seafood in a crisper bag or crisper and put it in the refrigerator to freeze it before cooking it next time.

Recently, there have been remarks on the Internet about "overnight dishes cause cancer".

Generally, you should not eat it again after eight hours, because as time goes by, the taste of the rice is not as good as before, and it is easy to be contaminated by other bacteria, so you should not eat it again after more than one night or 6 or 8 hours.

"Overnight dishes"It doesn't just refer to dishes that have been left overnight, if they are left out for more than 8-10 hours, they should be counted as overnight. There are two reasons for the increase in toxic ingredients in food, the first is that the chemicals in food produce carcinogens, such as nitrite, which cannot be removed even by heating.

The danger of overnight dishes is that they can breed bacteria and produce nitrites, which can cause infection or poisoning in humans.

Overnight meals are generally about eight hours long and produce a lot of nitrites. Harmful to the body.

It is recommended not to eat leftovers after 6 hours. The storage time of leftovers is generally 5 to 6 hours, and it is recommended that it is best not to skip meals, let alone overnight, for the following reasons:

1.If leftovers are left for too long, especially some overnight dishes, such as green leafy vegetables, etc., they will lose their nutritional value in the first place, and nitrite will also be produced, and the longer they are left and the higher the temperature, the more nitrite will be produced, and nitrite is a carcinogen.

2.If it is a high-fat and high-protein leftover, it is not allowed to eat, because harmful bacteria in the air will quickly attach to the leftovers and multiply rapidly, resulting in harmful substances.

Today we will discuss, how many hours apart is an overnight dish?

An overnight dish is not an overnight dish, but theoretically more than 5-8 hours is already considered an overnight dish. The reason for this is that they are severely infected by bacteria. It is easy to have an effect on the body's digestive system.

Therefore, it is better to throw away the leftovers that you can't eat. If you don't throw it out, wrap it in plastic wrap and put it in the refrigerator in time.

Let's talk about it in detail.

First, from a food science point of view, overnight is not a problem. The essence of the problem is what happens to the preservation of the prepared dish, and we are concerned about the conversion of nitrates into nitrite in the vegetables. This transformation process can be achieved by the original reductase enzymes in the vegetable, but when the vegetable is heated and cooked, these enzymes lose their activity and this path is truncated.

Second, the other pathway is the action of bacteria. Originally, the vegetables were cooked, and the bacteria in them were almost killed. But in the process of eating, some bacteria on the chopsticks will enter the leftovers; During storage, some airborne bacteria may also enter.

Cooked vegetables are more suitable for bacterial growth, and under the right conditions, they can grow in large quantities, and nitrates can be converted to nitrite during the growth process.

Thirdly, such a process has nothing to do with whether it is overnight or not, but only with the conditions of preservation. How much nitrite will be produced in the final dish depends first on the vegetable itself; secondly, under what conditions cooked vegetables are stored; The third is how long it has been preserved. Overnight dishes do not refer to dishes that have been cooked overnight, and they are generally left out for 5-8 hours to be considered overnight.

Vegetables cooked in summer will spoil without overnight, so overnight dishes should be judged from the storage temperature, confidentiality, and length of time of the dishes.

Summary

Overnight dishes, especially in summer, should not be kept if they are not finished. It's better to pour it out. Because the cost is not high. Cooked food or other foods that are relatively easy to preserve should also be stored in the refrigerator to avoid the growth of bacteria.

Overnight dishes are generally considered real overnight dishes for more than 4 hours, and there are already bacteria in them, so don't eat them anymore, such dishes should be thrown away, because there are carcinogenic substances in the dishes.

Generally, after cooking, the interval of 12 hours is considered overnight. If it is more than 12 hours, but if it is kept in the refrigerator, you can cook it again. It is best not to eat for more than 16 hours.

Generally, if the finished dish is more than 12 hours apart, it can be called an overnight dish, and it is best not to eat the overnight dish, which is harmful to the body.

Overnight dishes are dishes that last more than 8 to 10 hours, because the food placed during this time period produces nitrous carcinogens that cannot be removed by reheating. Nitrite is very harmful to the human body, and long-term consumption will cause cancer, and serious direct food poisoning is common.

An overnight dish literally means a dish that has been left overnight, and about 12 hours have basically passed by the next morning, which is commonly known as an "overnight dish". From a scientific point of view, overnight dishes are not because of overnight problems, even if they are cooked in the morning, they are also overnight dishes when they are eaten at dinner.

Cooked seafood, vegetables, and cold foods are best not to be left for 8 to 10 hours before eating again. The protein in cooked seafood that has been left for 8-10 hours is prone to degraders and can easily damage the kidneys and liver. The chlorophyll of leafy vegetables increases tenfold with each return to the pot.

If you want to eat an "overnight dish" for the second meal, try not to choose vegetables with leaves and stems. Cold food stored in the refrigerator will produce mold and chillophilia, and it is also not recommended to eat.

Left for 8 10 hours of bright silver "overnight" tea and "overnight" decoction of vitamins are greatly lost, and the proteins and sugars in them will become nutrients for mold. Tremella mushrooms that are often eaten at home are generally planted artificially, and a lot of nitrite will be produced after a long time, and they can only be cruelly thrown away. The same is true for Zen vegetable salad, which is not only unhealthy but also tastes bad.
