Meals should generally be placed at home, according to the kitchen room temperature of about 10 degrees, it should be able to be put on the 3rd day and will not spoil (that is, it is burned today, put it for a day tomorrow, and must be eaten the day after tomorrow); After a long time, it will definitely deteriorate.

The key points for preserving meals are, firstly, to sterilize them as thoroughly as possible, secondly, to store them in a sealed manner, and thirdly, to store them at low temperatures. Usually, you can prepare some glass crisper boxes, disinfect them thoroughly (steam or boil them in water for 5 minutes), and then cover them tightly and set them back. Meals that cannot be eaten should be thoroughly heated and sterilized (steamed for 5 minutes or more), and then put into a sterilized fresh-keeping box and stored in the deep refrigerator of the refrigerator, which can be kept basically safe to eat for about a week.

In addition, meat, such as stewed meat, can be stored in the freezer, thawed and heated when eaten.

If it is in the Northeast, then there is no problem with winter meals for three days.

If it's winter in Hainan, it will be bad if you leave it for a day.

So, how long do winter meals last? Decisions should be made based on the actual place, and decisions should be made according to the temperature.

In summer, meals can be stored at room temperature for about 4 hours. The temperature is high in summer, and the food is easy to spoil, but if the indoor temperature is not too high, it is generally no problem to eat the meal in the morning at noon, but it may spoil at night, and even if it can be eaten, the nutrients in the food are not as much as in the morning.

Summer is the second season of the year, from the beginning of summer to the beginning of autumn, and the most significant climate feature of summer is high temperatures.

In summer, the monsoon region in the southeast of China is hot and rainy, the southwest high-altitude area is cool and has little precipitation, and the northwest region.

Hot and dry. In China, the summer solstice is always on June 21 or 22 of the Gregorian calendar, when the sun shines directly on the Tropic of Capricorn.

In summer, leftovers can be stored for about 2 to 4 hours at room temperature. It is recommended that the cooked rice should not exceed 2 hours at room temperature, and it needs to be eaten as soon as possible or placed in the refrigerator for refrigeration, if it is at room temperature for more than 4 hours, it is recommended to heat it fully before eating, and if it spoils, throw it away directly.

In summer, the climate is hot, the temperature at room temperature is too high, if you can't finish the cooked rice, try not to put it at room temperature, the leftovers are easy to react with the air and deteriorate.

Harmful bacteria in the air will generally attach to some high protein within 2 hours.

High-fat leftovers multiply and produce harmful substances, so it is best to keep them in the refrigerator within 2 hours of cooking.

It is best not to put leftovers in aluminum utensils, because aluminum is easy to form alumina film in the air, which has adverse effects on the body, and can be stored in porcelain and then used plastic wrap.

Put it in the refrigerator.

Winter leftovers can be left for 5-6 hours. The storage time of leftovers should be not separated meals, eat in the morning and lunch, eat in the afternoon and eat in the evening, try to solve it within 5 or 6 hours, and it is best not to eat overnight dishes.

Some overnight dishes are not only not highly nutritious, but also produce nitrites.

The amount of nitrite produced in stored vegetables increases with longer storage time and higher temperature, while if vegetables are refrigerated in the refrigerator (2--6 degrees Celsius.

then the increase in nitrite is less. It is worth mentioning that the amount of nitrite produced by different types of vegetables under the same storage conditions is not consistent.

In general, stem and leaf vegetables are the highest, melon vegetables are slightly lower, and root and cauliflower vegetables are in the middle. Therefore, if you buy different kinds of vegetables at the same time, you should eat stems and leaves first, such as Chinese cabbage, spinach, etc. If you are going to cook more vegetables and eat them hot on the second day, you should try to make less stem and leaf vegetables and choose melon vegetables.

Leftovers should be cooled promptly and stored in the refrigerator

For stews and stir-fried vegetables with soup, it is generally necessary to wait for them to cool and then cover them with plastic wrap.

Put it in the refrigerator for storage, and put it in the refrigerator in time, even in winter, it can not be placed outside for a long time, otherwise it is easy for bacteria to invade, but the refrigerator has a certain antibacterial effect. The second is that different leftovers should be stored separately, vegetables and vegetables should be put together, and meat and meat should be put together to avoid cross-infection of bacteria.

Storing food at the right temperature can inhibit the growth of microorganisms in food and reduce the risk of food safety. If food is stored at room temperature, microorganisms can multiply rapidly, causing food spoilage. Therefore, cooked food should not be stored at room temperature for more than 2 hours, and all cooked food should be cooled and refrigerated in time, preferably at a temperature below 5 degrees Celsius.

Stews depend on the temperature and the ingredients of the food.

For example, in winter, it is 6 degrees today, and today it is minus 6 degrees, of course, the lower the temperature, the better it can be stored. But it also depends on the ingredients, such as vegetables in the stew, such as bean sprouts, Chinese cabbage, radish greens, etc., the taste is particularly bad after freezing, and the vegetables should not be eaten overnight, so as not to cause physical harm. Vegetables that have been left overnight cannot be eaten.

Not even in winter. But if it is meat dishes such as pork, chicken, beef, etc., it is still left for a few days, and the weather is cold for a week. When the temperature is high, it can also be stored in the refrigerator, with a layer of plastic wrap on the outside.

Stews can be left for about two days in winter, and the taste becomes worse after a long time, so it is best to eat them on the same day, and it is best to eat fresh ones for the stomach.

If you put it in the refrigerator, the stew can be stored for two days in winter.

If you don't put it in the refrigerator, you can only keep it for 1 day.

The refrigerator refrigeration temperature is generally 5 degrees Celsius, and the rate of bacterial growth will be inhibited under such temperature conditions, but the refrigerator is not a safe, and some bacteria can grow even if they are thrown at 5 degrees Celsius.

The best thing is not to store, storage can not exceed three days at most, generally it is not good after one day, now there is a refrigerator can still be stored, in short, it is still fresh.

The general fresh-keeping box is not good, one is that the stir-fry can be kept fresh for up to 2 days, add more salt to the day, and then the fear of secondary pollution in the middle, the express company can not keep you fresh, unless you have sealing equipment, and then fill nitrogen.

Leftovers in the winter for a few days stew, if you don't put it in the refrigerator, if you put it outside, and it has to be a cool place on the windowsill, there should be no problem for two days, if it is a long time, then it will not work, if the floor heat in your house is very hot, then you may also put a night, put it the next day and then put it for a night, it may not work, this has to design the temperature, you put the place can not be fixed? To tell you a few days, is it with the ambient stud root temperature stud earring? But no matter how many days you put it in, since you play with the dishes, don't I suggest you put it in the refrigerator?

You can't eat it all year round, and it's risky to put it in the refrigerator as much as possible, so do you try to do as little as possible? Don't eat overnight dishes, it's better not to put it for a day, right? Can't you invite health care now?

Whether it's stir-fried or stewed, the reality is that freshly made is best.

1. In winter, if the ambient temperature is 2-6, then the rice can be sealed and stored at room temperature, and it can generally be stored for 2 days.

2. The preservation of rice in the refrigerator is generally not more than 4 days, and the shelf life of rice is limited, especially the longer the refrigeration time, the harder the rice, and mold will be produced.

3. Rice will not age in an environment below -18, so leftover rice can be stored for a long time as long as it is put in the freezer, about half a month, and heated thoroughly when it is taken out again.

In winter, meals can be stored at room temperature for 2 to 3 days, and in winter, the temperature is low, and bacteria and microorganisms grow slowly, so the preservation time of meals can be extended, and plastic wrap should be used when storing meals.

Seal tightly to avoid prolonged contact with air, nitrite will be formed after the meal has been left for a long time.

substances, which are carcinogens.

How long can winter meals last at room temperature.

Winter meals can be stored at room temperature for 2 to 3 days, because the temperature is relatively low in winter, so it can inhibit the breeding and reproduction of bacteria to a certain extent, so the preservation time of meals can be extended, but the storage time should not be too long, and it should be eaten as soon as possible.

2. How to save it.

In winter, the food can be sealed and stored if it is not eaten, first put the food in the bowl, and then use plastic wrap to seal the bowl mouth to reduce the contact between the food and the air, so as to avoid oxidation of the meal, and then store the sealed meal in a ventilated and cool place.

3. Precautions.

Meals should be cooked and eaten fresh, and if the meal is left out for a long time, nitrite substances will be produced, which can lower the hemoglobin in the body.

The ability to produce nitrosamines in the human body if leftovers are consumed for a long time.

substances, which can cause harm to human health.
