Can you eat winter leftovers, and how many days can you keep winter leftovers?

Generally, stem and leaf vegetables have the highest nitrate content, melon vegetables are slightly lower, and root and cauliflower vegetables are in the middle. Therefore, if you buy a lot of vegetables at the same time, you should eat leafy vegetables first, such as Chinese cabbage, spinach, etc. If you are going to cook more vegetables and eat them hot the next day, you should try to make less stem and leaf vegetables and choose melon vegetables.

Overnight dishes do not refer to the dishes that have been put overnight, but refer to the dishes that have been placed for more than 8 hours, 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, which has a carcinogenic effect and cannot be removed by heating.

Extended Materials. Thrift is thrifty, but as everyone knows, overnight dishes not only have serious nutrient loss, but also produce substances that are harmful to the body. It is important to remind everyone that vegetables and seafood should not be eaten overnight, and meat must be steamed and cooked thoroughly when eating, so as to prevent food from being stored for a long time, spoiling, and causing food poisoning.

It is said that the low incidence of stomach cancer is related to the habit of not eating overnight vegetables. Since some green leafy vegetables contain more nitrates, if they are left for too long after cooking, the nitrate will be reduced to nitrite under the decomposition of bacteria, which has carcinogenic effects and cannot be removed by heating.

Healthy way to eat: Usually stem and leaf vegetables have the highest nitrate content, melon vegetables are slightly lower, and root and cauliflower 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 the next day, you should try to make less stem and leaf vegetables and choose melon vegetables.

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.

If it is a vegetable for the overnight dish in winter, it is recommended not to eat it again. There is oil and salt in the fried dish, and after one night, the vitamins in the dish are oxidized, which greatly increases the nitrite content, and becomes nitrite after entering the stomach, although nitrate is not a direct carcinogen, but it is a major hidden danger to health.

After nitrite enters the stomach, it produces a substance called NC (N-nitroso compound) when certain conditions are met, which is one of the risk factors for gastric cancer. It's winter, and some families think that the weather is cold and leftovers don't need to be put in the refrigerator, which is also wrong. Now, the widespread use of refrigerators in cities has reduced the nitrite content of people's intake from food, but it does not mean that vegetables can be put in the refrigerator with complete confidence; Over time, the nitrite content will still increase.

Therefore, vegetables must be eaten in time, and they should not be left for too long if they are not finished, resulting in an increase in nitrite content.

Winter leftovers need to be put in the refrigerator, the refrigerator temperature is more balanced, and the space is small, which can reduce the contact between food and bacteria, winter leftovers need to be completely heated and sterilized, and then sealed with plastic wrap and stored in the refrigerator, the storage time can not exceed 3 days at most, and it should be eaten as soon as possible.

Do you need to put winter leftovers in the refrigerator.

1. It needs to be stored.

Winter leftovers need to be put in the refrigerator, the space in the refrigerator is smaller, the air mobility is weaker, which can inhibit the spread of bacteria, and the temperature environment in the refrigerator is more balanced, while the room temperature will have some fluctuations, which may accelerate the deterioration of food, so winter leftovers need to be stored in the refrigerator.

2. Refrigeration method.

Winter leftovers need to be put into a pot to heat up completely before refrigeration, and then put them in a crisper box, wrap them completely with plastic wrap and put them in the refrigerator for storage.

3. Storage time.

Winter leftovers are stored in the refrigerated area for up to 3 days, so leftovers should be eaten as soon as possible, and after being left for a long time, it may cause the loss of nutrients in the food, and it needs to be completely heated before eating the refrigerator food before eating, so as not to affect human health.
